Upgrade to 3.0

We took advantage of the major release to fix all the problems in react-admin that required a breaking change. As a consequence, you'll need to do many small changes in the code of existing react-admin v2 applications. Follow this step-by-step guide to upgrade to react-admin v3.

Upgrade all react-admin packages

In the packages.json, upgrade ALL react-admin related dependencies to 3.0.0. This includes react-admin, ra-language-XXX, ra-data-XXX, etc.

{
    "name": "demo",
    "version": "0.1.0",
    "private": true,
    "dependencies": {
-       "ra-data-simple-rest": "^2.9.6",
+       "ra-data-simple-rest": "^3.0.0",
-       "ra-input-rich-text": "^2.9.6",
+       "ra-input-rich-text": "^3.0.0",
-       "ra-language-english": "^2.9.6",
+       "ra-language-english": "^3.0.0",
-       "ra-language-french": "^2.9.6",
+       "ra-language-french": "^3.0.0",
-       "react-admin": "^2.9.6",
+       "react-admin": "^3.0.0",
        "react": "^16.9.0",
        "react-dom": "^16.9.0",
        ...
    },

Failing to upgrade one of the ra- packages will result in a duplication of the react-admin package in two incompatible versions, and cause hard-to-debug bugs.

Increased version requirement for key dependencies

react and react-dom are now required to be >= 16.9. This version is backward compatible with 16.3, which was the minimum requirement in react-admin, and it offers the support for Hooks, on which react-admin v3 relies heavily.
react-redux requires a minimum version of 7.1.0 (instead of 5.0). Check their upgrade guide for 6.0 and 7.0
redux-saga requires a minimim version of 1.0.0 (instead of ~0.16.0). Check their list of breaking changes for redux-saga 1.0 on GitHub.
material-ui requires a minimum of 4.0.0 (instead of 1.5). Check their Upgrade guide.

`react-router-redux` replaced by `connected-react-router`

We've replaced the react-router-redux package, which was deprecated and not compatible with the latest version of react-redux, by an equivalent package named connected-react-router. As they share the same API, you can just change the import statement and it should work fine.

-import { push } from 'react-router-redux';
+import { push } from 'connected-react-router';

-import { LOCATION_CHANGE } from 'react-router-redux';
+import { LOCATION_CHANGE } from 'connected-react-router';

It's a bit more work if you're using a Custom App, as the initialization of connected-react-router requires one more step than react-router-redux.

If you create a custom reducer, here is how to update your createAdminStore file:

import { applyMiddleware, combineReducers, compose, createStore } from 'redux';
-import { routerMiddleware, routerReducer } from 'react-router-redux';
+import { routerMiddleware, connectRouter } from 'connected-react-router';
-import { reducer as formReducer } from 'redux-form';

...

export default ({
    authProvider,
    dataProvider,
    history,
    locale = 'en',
}) => {
    const reducer = combineReducers({
        admin: adminReducer,
-       form: formReducer,
-       router: routerReducer,
+       router: connectRouter(history),
        { /* add your own reducers here */ },
    });
    ...

The syntax of the routerMiddleware doesn't change.

And if you don't use the <Admin> component, change the package for ConnectedRouter:

import React from 'react';
import { Provider } from 'react-redux';
import { createHashHistory } from 'history';
-import { ConnectedRouter } from 'react-router-redux';
+import { ConnectedRouter } from 'connected-react-router';
import { Switch, Route } from 'react-router-dom';
import withContext from 'recompose/withContext';
...

`redux-form` replaced by `react-final-form`

The author of redux-form has written a new Form library for React called react-final-form to fix all the problems that redux-form had by construction. react-final-form no longer stores the form state in Redux. But the two libraries share a similar API. So in many cases, changing the imported package will suffice:

-import { Field } from 'redux-form';
+import { Field } from 'react-final-form';

The next sections highlight changes that you must do to your code as a consequence of switching to react-final-form.

Custom Form Toolbar or Buttons Must Use New `handleSubmit` Signature or must Use `onSave`

If you were using custom buttons (to alter the form values before submit for example), you'll need to update your code. In react-admin v2, the form toolbar and its buttons used to receive handleSubmit and handleSubmitWithRedirect props. These props accepted functions which were called with the form values.

The migration to react-final-form changes their signature and behavior to the following:

handleSubmit: accepts no arguments, and will submit the form with its current values immediately
handleSubmitWithRedirect accepts a custom redirect, and will submit the form with its current values immediately

Here's how to migrate the Altering the Form Values before Submitting example from the documentation:

import React, { useCallback } from 'react';
import { useForm } from 'react-final-form';
import { SaveButton, Toolbar, useCreate, useRedirect, useNotify } from 'react-admin';

const SaveWithNoteButton = ({ handleSubmit, handleSubmitWithRedirect, ...props }) => {
    const [create] = useCreate('posts');
    const redirectTo = useRedirect();
    const notify = useNotify();
    const { basePath, redirect } = props;

    const form = useForm();

    const handleClick = useCallback(() => {
        form.change('average_note', 10);

        handleSubmitWithRedirect('edit');
    }, [form]);

    return <SaveButton {...props} handleSubmitWithRedirect={handleClick} />;
};

The override of these functions has now a huge drawback, which makes it impractical: by skipping the default handleSubmitWithRedirect, the button doesn't trigger form validation. And unfortunately, react-final-form doesn't provide a way to trigger form validation manually. That's why react-admin now provides a way to override just the data provider call and its side effect called onSave.

The onSave value should be a function expecting 2 arguments: the form values to save, and the redirection to perform.

Here's how to migrate the Using onSave To Alter the Form Submission Behavior example from the documentation:

import React, { useCallback } from 'react';
import {
    SaveButton,
    Toolbar,
    useCreate,
    useRedirect,
    useNotify,
} from 'react-admin';

const SaveWithNoteButton = props => {
    const [create] = useCreate('posts');
    const redirectTo = useRedirect();
    const notify = useNotify();
    const { basePath } = props;

    const handleSave = useCallback(
        (values, redirect) => {
            create(
                {
                    payload: { data: { ...values, average_note: 10 } },
                },
                {
                    onSuccess: ({ data: newRecord }) => {
                        notify('ra.notification.created', 'info', {
                            smart_count: 1,
                        });
                        redirectTo(redirect, basePath, newRecord.id, newRecord);
                    },
                }
            );
        },
        [create, notify, redirectTo, basePath]
    );

    // set onSave props instead of handleSubmitWithRedirect
    return <SaveButton {...props} onSave={handleSave} />;
};

`FormDataConsumer` Children No Longer Receives `dispatch`

In react-admin v2, you could link two inputs using the FormDataConsumer component. The render prop function received the dispatch function that it could use to trigger form changes.

The migration to react-final-form changes this render prop signature a little as it will no longer receive a dispatch function. However, it's possible to use the useForm hook from react-final-form to achieve the same behavior:

import React, { Fragment } from 'react';
-import { change } from 'redux-form';
+import { useForm } from 'react-final-form';
import { FormDataConsumer, REDUX_FORM_NAME } from 'react-admin';

+const OrderOrigin = ({ formData, ...rest }) => {
+    const form = useForm();
+
+    return (
+        <Fragment>
+            <SelectInput
+                source="country"
+                choices={countries}
+                onChange={value => form.change('city', value)}
+                {...rest}
+            />
+            <SelectInput
+                source="city"
+                choices={getCitiesFor(formData.country)}
+                {...rest}
+            />
+        </Fragment>
+    );
+};

const OrderEdit = (props) => (
    <Edit {...props}>
        <SimpleForm>
            <FormDataConsumer>
-                {({ formData, dispatch, ...rest }) => (
-                    <Fragment>
-                        <SelectInput
-                            source="country"
-                            choices={countries}
-                            onChange={value => dispatch(
-                                change(REDUX_FORM_NAME, 'city', value)
-                            )}
-                             {...rest}
-                        />
-                        <SelectInput
-                            source="city"
-                            choices={getCitiesFor(formData.country)}
-                             {...rest}
-                        />
-                    </Fragment>
-                )}
+                {formDataProps => {
+                    <OrderOrigin {...formDataProps} />
+                }}
            </FormDataConsumer>
        </SimpleForm>
    </Edit>
);

Validators Should Return Non-Translated Messages

Form validators used to return translated error messages - that's why they received the field props as argument, including the translate function. They don't receive these props anymore, and they must return untranslated messages instead - react-admin translates validation messages afterwards.

// in validators/required.js
-const required = () => (value, allValues, props) =>
+const required = () => (value, allValues) =>
    value
        ? undefined
-       : props.translate('myroot.validation.required');
+       : 'myroot.validation.required';

In case the error message depends on a variable, you can return an object { message, args } instead of a message string:

-const minLength = (min) => (value, allValues, props) => 
+const minLength = (min) => (value, allValues) => 
    value.length >= min
        ? undefined
-       : props.translate('myroot.validation.minLength', { min });
+       : { message: 'myroot.validation.minLength', args: { min } };

React-admin core validators have been modified so you don't have to change anything when using them.

import {
    required,
    minLength,
    maxLength,
    minValue,
    number,
    email,
} from 'react-admin';

// no change vs 2.x
const validateFirstName = [required(), minLength(2), maxLength(15)];
const validateEmail = email();
const validateAge = [number(), minValue(18)];

export const UserCreate = (props) => (
    <Create {...props}>
        <SimpleForm>
            <TextInput label="First Name" source="firstName" validate={validateFirstName} />
            <TextInput label="Email" source="email" validate={validateEmail} />
            <TextInput label="Age" source="age" validate={validateAge}/>
        </SimpleForm>
    </Create>
);

Migration to react-final-form Requires Custom App Modification

We used to implement some black magic in formMiddleware to handle redux-form correctly. It is no longer necessary now that we migrated to react-final-form. Besides, redux-form required a reducer which is no longer needed as well.

If you had your own custom Redux store, you can migrate it by following this diff:

// in src/createAdminStore.js
import { applyMiddleware, combineReducers, compose, createStore } from 'redux';
import { routerMiddleware, connectRouter } from 'connected-react-router';
-import { reducer as formReducer } from 'redux-form';
import createSagaMiddleware from 'redux-saga';
import { all, fork } from 'redux-saga/effects';
import {
    adminReducer,
    adminSaga,
    createAppReducer,
    defaultI18nProvider,
    i18nReducer,
-   formMiddleware,
    USER_LOGOUT,
} from 'react-admin';

export default ({
    authProvider,
    dataProvider,
    i18nProvider = defaultI18nProvider,
    history,
    locale = 'en',
}) => {
    const reducer = combineReducers({
        admin: adminReducer,
        i18n: i18nReducer(locale, i18nProvider(locale)),
-       form: formReducer,
        router: connectRouter(history),
        { /* add your own reducers here */ },
    });
    const resettableAppReducer = (state, action) =>
        reducer(action.type !== USER_LOGOUT ? state : undefined, action);

    const saga = function* rootSaga() {
        yield all(
            [
                adminSaga(dataProvider, authProvider, i18nProvider),
                // add your own sagas here
            ].map(fork)
        );
    };
    const sagaMiddleware = createSagaMiddleware();

    const store = createStore(
        resettableAppReducer,
        { /* set your initial state here */ },
        compose(
            applyMiddleware(
                sagaMiddleware,
-               formMiddleware,
                routerMiddleware(history),
                // add your own middlewares here
            ),
            typeof window !== 'undefined' && window.__REDUX_DEVTOOLS_EXTENSION__
                ? window.__REDUX_DEVTOOLS_EXTENSION__()
                : f => f
            // add your own enhancers here
        )
    );
    sagaMiddleware.run(saga);
    return store;
};

Custom Forms Using `reduxForm()` Must Be Replaced By The `<Form>` Component

The final-form migration documentation here explains the various changes you have to perform in your code.

-import { reduxForm } from 'redux-form'
+import { Form } from 'react-final-form'

-const CustomForm = reduxForm({ form: 'record-form', someOptions: true })(({ record, resource }) => (
+const CustomForm = ({ record, resource }) => (
+    <Form someOptions={true}>
+        {({ handleSubmit }) => (
+            <form onSubmit={handleSubmit}>
-            <Fragment>
                <Typography>Notes</Typography>
                <TextInput source="note" />
+            </form>
-            </Fragment>
+        )}
+    </Form>
+);
-));

Material-ui Icons Have Changed

If you were using Material-ui icons for your design, be aware that some icons present in 1.X versions were removed from version 4.0.

Example:

LightbulbOutline is no more available in @Material-ui/icons

But there is a quick fix for this one by using another package instead:

import Lightbulb from '@material-ui/docs/svgIcons/LightbulbOutline';

Custom Exporter Functions Must Use `jsonexport` Instead Of `papaparse`

React-admin used to bundle the papaparse library for converting JSON to CSV, as part of the Export functionality. But 90% of the papaparse code is used to convert CSV to JSON and was useless in react-admin. We decided to replace it by a lighter library: jsonexport.

If you had custom exporter on List components, here's how to migrate:

-import { unparse as convertToCSV } from 'papaparse/papaparse.min';
+import jsonExport from 'jsonexport/dist';

-const csv = convertToCSV({
-    data: postsForExport,
-    fields: ['id', 'title', 'author_name', 'body']
-});
-downloadCSV(csv, 'posts');
+jsonExport(postsForExport, {
+    headers: ['id', 'title', 'author_name', 'body']
+}, (err, csv) => {
+    downloadCSV(csv, 'posts');
+});

The `exporter` Function Has Changed Signature

In a List, you can pass a custom exporter function to control the data downloaded by users when they click on the "Export" button.

const CommentList = props => (
    <List {...props} exporter={exportComments}>
        // ...
    </List>
)

In react-admin v3, you can still pass an exporter function this way, but its signature has changed:

-const exportComments = (data, fetchRelaterRecords, dispatch) => {
+const exportComments = (data, fetchRelaterRecords, dataProvider) => {
    // ...
}

If you used dispatch to call the dataProvider using an action creator with a callback side effect, you will see that the v3 version makes your exporter code much simpler. If you used it to dispatch custom side effects (like notification or redirect), we recommend that you override the <ExportButton> component completely - it'll be much easier to maintain.

As a base, here is the simplified ExportButton code:

import {
    downloadCSV,
    useDataProvider,
    useNotify,
} from 'react-admin';
import jsonExport from 'jsonexport/dist';

const ExportButton = ({ sort, filter, maxResults = 1000, resource }) => {
    const dataProvider = useDataProvider();
    const notify = useNotify();
    const payload = { sort, filter, pagination: { page: 1, perPage: maxResults }}
    const handleClick = dataProvider.getList(resource, payload)
        .then(({ data }) => jsonExport(data, (err, csv) => downloadCSV(csv, resource)))
        .catch(error => notify('ra.notification.http_error', 'warning'));

    return (
        <Button
            label="Export"
            onClick={handleClick}
        />
    );
};

`authProvider` No Longer Uses Legacy React Context

When you provide an authProvider to the <Admin> component, react-admin creates a React context to make it available everywhere in the application. In version 2.x, this used the legacy React context API. In 3.0, this uses the normal context API. That means that any context consumer will need to use the new context API.

-import React from 'react';
+import React, { useContext } from 'react';
+import { AuthContext } from 'react-admin';

-const MyComponentWithAuthProvider = (props, context) => {
+const MyComponentWithAuthProvider = (props) => {
+   const authProvider = useContext(AuthContext);
    authProvider('AUTH_CHECK');
    return <div>I'm authenticated</div>;
}

-MyComponentWithAuthProvider.contextTypes = { authProvider: PropTypes.object }

If you didn't access the authProvider context manually, you have nothing to change. All react-admin components have been updated to use the new context API.

Note that direct access to the authProvider from the context is discouraged (and not documented). If you need to interact with the authProvider, use the new auth hooks:

useLogin
useLogout
useAuthenticated
useAuthState
usePermissions

`authProvider` No Longer Receives `match` in Params

Whenever it called the authProvider, react-admin used to pass both the location and the match object from react-router. In v3, the match object is no longer passed as argument. There is no legitimate usage of this parameter we can think about, and it forced passing down that object across several components for nothing, so it's been removed. Upgrade your authProvider to remove that parameter.

// in src/authProvider
export default (type, params) => {
-   const { location, match } = params;
+   const { location } = params;
    // ...
}

The `authProvider` Must Handle Permissions

React-admin calls the authProvider to get the permissions for each page - using the AUTH_GET_PERMISSIONS verb. While in 2.x, implementing this AUTH_GET_PERMISSIONS verb was optional, it becomes compulsory in 3.0 as soon as you provide a custom authProvider. You can simply return a resolved Promise to ignore permissions handling.

// in src/authProvider.js
-import { AUTH_LOGIN, AUTH_LOGOUT, AUTH_ERROR, AUTH_CHECK } from 'react-admin';
+import { AUTH_LOGIN, AUTH_LOGOUT, AUTH_ERROR, AUTH_CHECK, AUTH_GET_PERMISSIONS } from 'react-admin';

export default (type, params) => {
    if (type === AUTH_LOGIN) {
        // ...
    }
    if (type === AUTH_LOGOUT) {
        // ...
    }
    if (type === AUTH_ERROR) {
        // ...
    }
    if (type === AUTH_CHECK) {
        const { resource } = params;
        if (resource === 'posts') {
            // check credentials for the posts resource
        }
        if (resource === 'comments') {
            // check credentials for the comments resource
        }
    }
+   if (type === AUTH_GET_PERMISSIONS) {
+       return Promise.resolve();
+   }
    return Promise.reject('Unknown method');
};

The `authProvider` No Longer Receives Default Parameters

When calling the authProvider for permissions (with the AUTH_GET_PERMISSIONS verb), react-admin used to include the pathname as second parameter. That allowed you to return different permissions based on the page. In a similar fashion, for the AUTH_CHECK call, the params argument contained the resource name, allowing different checks for different resources.

We believe that authentication and permissions should not vary depending on where you are in the application ; it's up to components to decide to do something or not depending on permissions. So we've removed the default parameters from all the authProvider calls.

If you want to keep location-dependent authentication or permissions logic, read the current location from the window object directly in your authProvider, using window.location.hash (if you use a hash router), or using window.location.pathname (if you use a browser router):

// in myauthProvider.js
import { AUTH_LOGIN, AUTH_LOGOUT, AUTH_ERROR, AUTH_GET_PERMISSIONS } from 'react-admin';
import decodeJwt from 'jwt-decode';

export default (type, params) => {
    if (type === AUTH_CHECK) {
-       const { resource } = params;
+       const resource = window.location.hash.substring(2, window.location.hash.indexOf('/', 2))
        // resource-dependent logic follows
    }
    if (type === AUTH_GET_PERMISSIONS) {
-       const { pathname } = params;
+       const pathname = window.location.hash;
        // pathname-dependent logic follows 
        // ...
    }
    return Promise.reject('Unknown method');
};

No More Redux Actions For Authentication

React-admin now uses hooks instead of sagas to handle authentication and authorization. That means that react-admin no longer dispatches the following actions:

USER_LOGIN
USER_LOGIN_LOADING
USER_LOGIN_FAILURE
USER_LOGIN_SUCCESS
USER_CHECK
USER_CHECK_SUCCESS
USER_LOGOUT

If you have custom Login or Logout buttons dispatching these actions, they will still work, but you are encouraged to migrate to the hook equivalents (useLogin and useLogout).

If you had custom reducer or sagas based on these actions, they will no longer work. You will have to reimplement that custom logic using the new authentication hooks.

Tip: If you need to clear the Redux state, you can dispatch the CLEAR_STATE action.

Login uses children instead of a loginForm prop

If you were using Login with a custom login form, you now need to pass that as a child instead of a prop of Login.

import { Login } from 'react-admin';
const LoginPage = () => (
     <Login
-        loginForm={<LoginForm />}
         backgroundImage={backgroundImage}
-    />
+    >
+        <LoginForm />
+    </Login>
 );

i18nProvider Signature Changed

The react-admin translation (i18n) layer lets developers provide translations for UI and content, based on Airbnb's Polyglot library. The i18nProvider, which contains that translation logic, used to be a function. It must now be an object exposing three methods: translate, changeLocale and getLocale.

// react-admin 2.x
const i18nProvider = (locale) => messages[locale];

// react-admin 3.x
const polyglot = new Polyglot({ locale: 'en', phrases: messages.en });
let translate = polyglot.t.bind(polyglot);
let locale = 'en';
const i18nProvider = {
    translate: (key, options) => translate(key, options),
    changeLocale: newLocale => {
        locale = newLocale;
        return new Promise((resolve, reject) => {
            // load new messages and update the translate function
        })
    },
    getLocale: () => locale;
}

But don't worry: react-admin v3 contains a module called ra-i18n-polyglot, that is a wrapper around your old i18nProvider to make it compatible with the new provider signature:

import React from 'react';
import { Admin, Resource } from 'react-admin';
+import polyglotI18nProvider from 'ra-i18n-polyglot';
import englishMessages from 'ra-language-english';
import frenchMessages from 'ra-language-french';

const messages = {
    fr: frenchMessages,
    en: englishMessages,
};
-const i18nProvider = locale => messages[locale];
+const i18nProvider = polyglotI18nProvider(locale => messages[locale], 'fr');

const App = () => (
-    <Admin locale="fr" i18nProvider={i18nProvider}>
+    <Admin i18nProvider={i18nProvider}>
        ...
    </Admin>
);

export default App;

Tip: The Admin component does not accept a locale prop anymore as it is the i18nProvider provider responsibility. Pass the initial locale as second argument to polyglotI18nProvider instead of passing it to Admin

The Translation Layer No Longer Uses Redux

The previous implementation if the i18n layer used Redux and redux-saga. In react-admin 3.0, the translation utilities are implemented using a React context and a set of hooks.

If you didn't use translations, or if you passed your i18nProvider to the <Admin> component and used only one language, you have nothing to change. Your app will continue to work just as before. We encourage you to migrate from the withTranslate HOC to the useTranslate hook, but that's not compulsory.

-import { withTranslate } from 'react-admin';
+import { useTranslate } from 'react-admin';

-const SettingsMenu = ({ translate }) => {
+const SettingsMenu = () => {
+   const translate = useTranslate();
    return <MenuItem>{translate('settings')}</MenuItem>;
}

-export default withTranslate(SettingsMenu);
+export default SettingsMenu;

However, if your app allowed users to change locale at runtime, you need to update the menu or button that triggers that locale change. Instead of dispatching a CHANGE_LOCALE Redux action (which has no effect in react-admin 3.0), use the useSetLocale hook as follows:

import React from 'react';
-import { connect } from 'react-redux';
import Button from '@material-ui/core/Button';
-import { changeLocale } from 'react-admin';
+import { useSetLocale } from 'react-admin';

-const localeSwitcher = ({ changeLocale }) => 
+const LocaleSwitcher = () => {
+   const setLocale = useSetLocale();
-   const switchToFrench = () => changeLocale('fr');
+   const switchToFrench = () => setLocale('fr');
-   const switchToEnglish = () => changeLocale('en');
+   const switchToEnglish = () => setLocale('en');
    return (
        <div>
            <div>Language</div>
            <Button onClick={switchToEnglish}>en</Button>
            <Button onClick={switchToFrench}>fr</Button>
        </div>
    );
}

-export default connect(null, { changeLocale })(LocaleSwitcher);
+export default LocaleSwitcher;

Also, if you connected a component to the Redux store to get the current language, you now need to use the useLocale() hook instead.

-import { connect } from 'react-redux';
+import { useLocale } from 'react-admin';

const availableLanguages = {
    en: 'English',
    fr: 'Français',
}

-const CurrentLanguage = ({ locale }) => {
+const CurrentLanguage = () => {
+   const locale = useLocale();
    return <span>{availableLanguages[locale]}</span>;
}

- const mapStatetoProps = state => state.i18n.locale

-export default connect(mapStateToProps)(CurrentLanguage);
+export default CurrentLanguage;

If you used a custom Redux store, you must update the createAdminStore call to omit the i18n details:

const App = () => (
    <Provider
        store={createAdminStore({
            authProvider,
            dataProvider,
-           i18nProvider,
            history,
        })}
    >
        <Admin
            authProvider={authProvider}
            dataProvider={dataProvider}
            history={history}
            title="My Admin"
        >

`withDataProvider` No Longer Injects `dispatch`

The withDataProvider HOC used to inject two props: dataProvider, and Redux' dispatch. This last prop is now easy to get via the useDispatch hook from Redux, so withDataProvider no longer injects it.

import {
   showNotification,
   UPDATE,
   withDataProvider,
} from 'react-admin';
+ import { useDispatch } from 'react-redux';

-const ApproveButton = ({ dataProvider, dispatch, record }) => {
+const ApproveButton = ({ dataProvider, record }) => {
+   const dispatch = useDispatch();
    const handleClick = () => {
        const updatedRecord = { ...record, is_approved: true };
        dataProvider(UPDATE, 'comments', { id: record.id, data: updatedRecord })
            .then(() => {
                dispatch(showNotification('Comment approved'));
                dispatch(push('/comments'));
            })
            .catch((e) => {
                dispatch(showNotification('Error: comment not approved', 'warning'))
            });
    }

    return <Button label="Approve" onClick={handleClick} />;
}

export default withDataProvider(ApproveButton);

Resource `context` Renamed to `intent`

If you're using a Custom App, you had to render <Resource> components with the registration context prior to rendering your app routes. The context prop was renamed to intent because it conflicted with a prop injected by react-redux.

-               <Resource name="posts" context="registration" />
+               <Resource name="posts" intent="registration" />
-               <Resource name="comments" context="registration" />
+               <Resource name="comments" intent="registration" />
-               <Resource name="users" context="registration" />
+               <Resource name="users" intent="registration" />

`<ReferenceField>` `linkType` Prop Renamed to `link`

When using the <ReferenceField> component, you should rename the linkType prop to link. This prop now also accepts custom functions to return a link (see the Fields documentation).

- <ReferenceField resource="comments" record={data[id]} source="post_id" reference="posts" basePath={basePath} linkType="show">
+ <ReferenceField resource="comments" record={data[id]} source="post_id" reference="posts" basePath={basePath} link="show">

`<CardActions>` Renamed to `<TopToolbar>`

The <CardActions> component, which used to wrap the action buttons in the Edit, Show and Create views, is now named <TopToolbar>. That's because actions aren't located inside the Card anymore, but above it.

import Button from '@material-ui/core/Button';
-import { CardActions, ShowButton } from 'react-admin';
+import { TopToolbar, ShowButton } from 'react-admin';

const PostEditActions = ({ basePath, data, resource }) => (
-   <CardActions>
+   <TopToolbar>
        <ShowButton basePath={basePath} record={data} />
        {/* Add your custom actions */}
        <Button color="primary" onClick={customAction}>Custom Action</Button>
-   </CardActions>
+   </TopToolbar>
);

export const PostEdit = (props) => (
    <Edit actions={<PostEditActions />} {...props}>
        ...
    </Edit>
);

But watch out, you can't just replace "CardActions" by "TopToolbar" in your entire codebase, because you probably also use material-ui's <CardActions>, and that component still exists. The fact that react-admin exported a component with the same name but with a different look and feel than the material-ui component was also a motivation to rename it.

`<Admin>` `appLayout` Prop Renamed To `layout`

You can inject a layout component in the <Admin> component to override the default layout. However, this injection used a counterintuitive prop name: appLayout. It has been renamed to the more natural layout.

You will only have to change your code if you used a custom layout:

const App = () => (
-   <Admin appLayout={MyLayout}>
+   <Admin layout={MyLayout}>
        <Resource name="posts" list={PostList} edit={PostEdit} />
    </Admin>
);

Prop `isLoading` Renamed To `loading`

Most of the react-admin controller components that fetch data used to inject an isLoading boolean prop, set to true whenever a dataProvider call was pending. This prop was renamed to loading everywhere. Use the search and replace feature of your IDE to rename that prop.

For instance:

  <ReferenceInputController {...props}>
-     {({ isLoading, otherProps }) => (
+     {({ loading, otherProps }) => (
          <CustomReferenceInputView
              {...otherProps}
-             isLoading={isLoading}
+             loading={loading}
          />
      )}
  </ReferenceInputController>

Prop `loadedOnce` Renamed To `loaded`

The List, ReferenceArrayfield and ReferenceManyField used to inject a loadedOnce prop to their child. This prop has been renamed to loaded.

As a consequence, the components usually used as child of these 3 components now accept a loaded prop instead of loadedOnce. This concerns Datagrid, SingleFieldList, and GridList.

This change is transparent unless you use a custom view component inside a List, ReferenceArrayfield or ReferenceManyField.

const PostList = props => (
    <List {...props}>
        <MyListView />
    </List>
)

-const MyListView = ({ loadedOnce, ...props }) => (
+const MyListView = ({ loaded, ...props }) => (
-   if (!loadedOnce) return null;
+   if (!loaded) return null;
    // rest of the view
);

Deprecated components were removed

Components deprecated in 2.X have been removed in 3.x. This includes:

AppBarMobile (use AppBar instead, which is responsive)
Header (use Title instead)
ViewTitle (use Title instead)
RecordTitle (use TitleForRecord instead)
TitleDeprecated (use Title instead)
Headroom (use HideOnScroll instead)
LongTextInput (use the TextInput instead)

- import { LongTextInput } from 'react-admin';
- <LongTextInput source="body" />
+ import { TextInput } from 'react-admin';
+ <TextInput multiline source="body" />

BulkActions (use the bulkActionButtons prop instead)

- const PostBulkActions = props => (
-     <BulkActions {...props}>
-         <CustomBulkMenuItem />
-         {/* Add the default bulk delete action */}
-         <BulkDeleteMenuItem />
-     </BulkActions>
- );
+ const PostBulkActionButtons = props => (
+     <Fragment>
+         <ResetViewsButton label="Reset Views" {...props} />
+         {/* Add the default bulk delete action */}
+         <BulkDeleteButton {...props} />
+     </Fragment>
+ );

export const PostList = (props) => (
    <List 
        {...props} 
-       bulkActions={<PostBulkActions />}
+       bulkActionButtons={<PostBulkActionButtons />}>
        ...
    </List>
);

The `DisabledInput` Component Was Removed

See RFC 3518 for the rationale.

You can replace <DisabledInput> with a disabled or read-only TextInput. For example, the disabled prop:

-import { DisabledInput } from 'react-admin';
+import { TextInput } from 'react-admin';

-<DisabledInput source="id" />
+<TextInput source="id" disabled />

See material-ui TextField documentation for available options.

The SideBar Width Must Be Set Through The `theme`

The <SideBar> component used to accept size and closedSize prop to control its width.

You can now customize those values by providing a custom material-ui theme.

import { createMuiTheme } from '@material-ui/core/styles';

const theme = createMuiTheme({
    sidebar: {
        width: 300, // The default value is 240
        closedWidth: 70, // The default value is 55
    },
});

const App = () => (
    <Admin theme={theme} dataProvider={simpleRestProvider('http://path.to.my.api')}>
        // ...
    </Admin>
);

Reference Inputs No Longer Inject A `helperText` field Inside `meta`

<ReferenceInput> used to send a helperText inside the meta prop of its child whenever it was unable to retrieve referenced records. The same goes for <ReferenceArrayInput>.

These components now use the meta: { error } prop and won't override their child helperText anymore.

Furthermore, they don't support the helperText at all anymore as this is a pure UI concern which should be handled by their child.

If you've implemented a custom child component for <ReferenceInput> of <ReferenceArrayInput>, you must now display the error in your component.

const MySelectIpnut = ({
    // ...
-   meta: { helperText }
+   meta: { error }
}) => (
    if (error) {
        // ReferenceInput couldn't check referenced records, and therefore the choices list is empty
        // display a custo merror message here.
    }
);

`helperText` Is Handled The Same Way In All Components

Somewhat related to the previous point, some components (such as <SelectArrayInput>) used to accept a helperText prop in their meta prop. They now receive it directly in their props.

Besides, all components now display their error or their helper text, but not both at the same time.

This has no impact unless you used to set the helperText manually in <SelectArrayInput>:

const Postedit = props =>
  <Edit {...props}>
      <SimpleForm>
          // ...
         <SelectArrayInput
            label="Tags"
            source="categories"
-           meta={{ helperText: 'Select categories' }}
+           helperText="Select categories"
            choices={[
             { id: 'music', name: 'Music' },
             { id: 'photography', name: 'Photo' },
             { id: 'programming', name: 'Code' },
             { id: 'tech', name: 'Technology' },
             { id: 'sport', name: 'Sport' },
            ]}
           />
      </SimpleForm>
  </Edit>

Form Inputs Are Now `filled` And `dense` By Default

To better match the Material Design specification, react-admin defaults to the filled variant for form inputs, and uses a dense margin to allow more compact forms. This will change the look and feel of existing forms built with <SimpleForm>, <TabbedForm>, and <Filter>. If you want your forms to look just like before, you need to set the variant and margin props as follows:

// for SimpleForm
const PostEdit = props =>
    <Edit {...props}>
        <SimpleForm
+           variant="standard"
+           margin="normal"
        >
            // ...
        </SimpleForm>
    </Edit>;
// for TabbedForm
const PostEdit = props =>
    <Edit {...props}>
        <TabbedForm
+           variant="standard"
+           margin="normal"
        >
            <FormTab label="Identity>
                // ...
            </FormTab>
        </TabbedForm>
    </Edit>;
// for Filter
const PostFilter = props => 
-   <Filter>
+   <Filter variant="standard">
        // ...
    </Filter>;

`<Form>` `defaultValue` Prop Was Renamed To `initialValues`

This is actually to be consistent with the underlying form library (final-form)

// for SimpleForm
const PostEdit = props =>
    <Edit {...props}>
        <SimpleForm
-           defaultValue={{ stock: 0 }}
+           initialValues={{ stock: 0 }}
        >
            // ...
        </SimpleForm>
    </Edit>;
// for TabbedForm
const PostEdit = props =>
    <Edit {...props}>
        <TabbedForm
-           defaultValue={{ stock: 0 }}
+           initialValues={{ stock: 0 }}
        >
            <FormTab label="Identity>
                // ...
            </FormTab>
        </TabbedForm>
    </Edit>;

Prefilling Some Fields Of A `<Create>` Page Needs Different URL Syntax

We've described how to pre-fill some fields in the create form in an Advanced Tutorial. In v2, you had to pass all the fields to be pre-filled as search parameters. In v3, you have to pass a single source search parameter containing a stringified object:

const AddNewCommentButton = ({ record }) => (
  <Button
    component={Link}
    to={{
      pathname: "/comments/create",
-     search: `?post_id=${record.id}`,
+     search: `?source=${JSON.stringify({ post_id: record.id })}`,
    }}
    label="Add a comment"
  >
    <ChatBubbleIcon />
  </Button>
);

That's what the <CloneButton> does in react-admin v3:

export const CloneButton = ({
    basePath = '',
    label = 'ra.action.clone',
    record = {},
    icon = <Queue />,
    ...rest
}) => (
    <Button
        component={Link}
        to={{
            pathname: `${basePath}/create`,
            search: stringify({ source: JSON.stringify(omitId(record)) }),
        }}
        label={label}
        onClick={stopPropagation}
        {...sanitizeRestProps(rest)}
    >
        {icon}
    </Button>
);

The `<AutocompleteInput>` And `<AutocompleteArrayInput>` Components No Longer Support Certain Props

We rewrote the <AutocompleteInput> and <AutocompleteArrayInput> components from scratch using downshift, while the previous version was based on react-autosuggest. The new components are more robust and more future-proof, and their API didn't change.

There are three breaking changes in the new <AutocompleteInput> and <AutocompleteArrayInput> components:

The inputValueMatcher prop is gone. We removed a feature many found confusing: the auto-selection of an item when it was matched exactly. So react-admin no longer selects anything automatically, therefore the inputValueMatcher prop is obsolete.

<AutocompleteInput
    source="role"
-   inputValueMatcher={() => null}
/>
<AutocompleteArrayInput
    source="role"
-   inputValueMatcher={() => null}
/>

Specific react-autosuggest props (like onSuggestionsFetchRequested, theme, or highlightFirstSuggestion) are no longer supported, because the component now passes extra props to a <Downshift> component.

<AutocompleteInput
    source="role"
-   highlightFirstSuggestion={true}
/>
<AutocompleteArrayInput
    source="role"
-   highlightFirstSuggestion={true}
/>

The suggestionComponent prop is gone.

Instead, the new <AutocompleteInput> and <AutocompleteArrayInput> components use the optionText prop, like all other inputs accepting choices. However, if you pass a React element as the optionText, you must now also specify the new matchSuggestion prop. This is required because the inputs use the optionText by default to filter suggestions. This function receives the current filter and a choice, and should return a boolean indicating whether this choice matches the filter.

<AutocompleteInput
    source="role"
-   suggestionComponent={MyComponent}
+   optionText={<MyComponent />}
+   matchSuggestion={matchSuggestion}
/>

<AutocompleteArrayInput
    source="role"
-   suggestionComponent={MyComponent}
+   optionText={<MyComponent />}
+   matchSuggestion={matchSuggestion}
/>

Besides, some props which were applicable to both components did not make sense for the <AutocompleteArrayInput> component:

allowEmpty: As the <AutocompleteArrayInput> deals with arrays, it does not make sense to add an empty choice. This prop is no longer accepted and will be ignored.
limitChoicesToValue: As the <AutocompleteArrayInput> deals with arrays and only accepts unique items, it does not make sense to show only the already selected items. This prop is no longer accepted and will be ignored.

<AutocompleteArrayInput
    source="role"
-   allowEmpty={true}
-   limitChoicesToValue={true}
/>

New DataProviderContext Requires Custom App Modification

The new dataProvider-related hooks (useQuery, useMutation, useDataProvider, etc.) grab the dataProvider instance from a new React context. If you use the <Admin> component, your app will continue to work and there is nothing to do, as <Admin> now provides that context. But if you use a Custom App, you'll need to set the value of that new DataProvider context:

-import { TranslationProvider, Resource } from 'react-admin';
+import { TranslationProvider, DataProviderContext, Resource } from 'react-admin';

const App = () => (
    <Provider
        store={createAdminStore({
            authProvider,
            dataProvider,
            i18nProvider,
            history,
        })}
    >
        <TranslationProvider>
+           <DataProviderContext.Provider value={dataProvider}>
                <ThemeProvider>
                    <Resource name="posts" intent="registration" />
                    ...
                    <AppBar position="static" color="default">
                        <Toolbar>
                            <Typography variant="h6" color="inherit">
                                My admin
                            </Typography>
                        </Toolbar>
                    </AppBar>
                    <ConnectedRouter history={history}>
                        <Switch>
                            <Route exact path="/" component={Dashboard} />
                            <Route exact path="/posts" hasCreate render={(routeProps) => <PostList resource="posts" {...routeProps} />} />
                            <Route exact path="/posts/create" render={(routeProps) => <PostCreate resource="posts" {...routeProps} />} />
                            <Route exact path="/posts/:id" hasShow render={(routeProps) => <PostEdit resource="posts" {...routeProps} />} />
                            <Route exact path="/posts/:id/show" hasEdit render={(routeProps) => <PostShow resource="posts" {...routeProps} />} />
                            ...
                        </Switch>
                    </ConnectedRouter>
                </ThemeProvider>
+           </DataProviderContext.Provider>
        </TranslationProvider>
    </Provider>
);

Note that if you were unit testing controller components, you'll probably need to add a mock dataProvider via <DataProviderContext> in your tests, too.

Custom `<Notification>` Components Must Emit UndoEvents

The undo feature is partially implemented in the Notification component. If you've overridden that component, you'll have to add a call to undoableEventEmitter in case of confirmation and undo:

// in src/MyNotification.js
import React from 'react';
import { connect } from 'react-redux';
import compose from 'recompose/compose';
import classnames from 'classnames';
import Snackbar from "@material-ui/core/Snackbar";
import { withStyles, createStyles } from "@material-ui/core";
import {
    complete,
    undo,
    translate,
    getNotification,
    hideNotification,
    Button,
+   undoableEventEmitter,
} from 'react-admin';

const styles = theme =>
  createStyles({
    confirm: {
      backgroundColor: theme.palette.background.default
    },
    warning: {
      backgroundColor: theme.palette.error.light
    },
    undo: {
      color: theme.palette.primary.light
    }
  });

class Notification extends React.Component {
    state = {
        open: false,
    };
    componentWillMount = () => {
        this.setOpenState(this.props);
    };
    componentWillReceiveProps = nextProps => {
        this.setOpenState(nextProps);
    };

    setOpenState = ({ notification }) => {
        this.setState({
            open: !!notification,
        });
    };

    handleRequestClose = () => {
        this.setState({
            open: false,
        });
    };

    handleExited = () => {
        const { notification, hideNotification, complete } = this.props;
        if (notification && notification.undoable) {
            complete();
+           undoableEventEmitter.emit('end', { isUndo: false });
        }
        hideNotification();
    };

    handleUndo = () => {
        const { undo } = this.props;
        undo();
+       undoableEventEmitter.emit('end', { isUndo: true });
    };

    render() {
        const {
            undo,

No More Tree Packages in Core

The ra-tree and ra-tree-ui-material-ui packages were removed in v3. The v2 version performed poorly, and we don't want to delay v3 to reimplement the Tree packages.

If you were using these packages just for displaying a tree, you'll have to reimplement a basic tree widget, taking the Tags list from the Simple example as an inspiration. If you were using these packages for creating and updating a tree, we recommend that you wait until the core team or another community member publishes a Tree package compatible with v3.
