This is a i18next backend to chain multiple [other backends](https://www.i18next.com/plugins-and-utils.html#backends) and caches. So you can define an additional caching backend or fallback backends.
# Getting started
Source can be loaded via [npm](https://www.npmjs.com/package/i18next-chained-backend) or [downloaded](https://github.com/i18next/i18next-chained-backend/blob/master/i18nextBackendBackend.min.js) from this repo.
```
# npm package
$ npm install i18next-chained-backend
```
Wiring up:
```js
import i18next from 'i18next';
import Backend from 'i18next-chained-backend';
i18next
.use(Backend)
.init(i18nextOptions);
```
- As with all modules you can either pass the constructor function (class) to the i18next.use or a concrete instance.
- If you don't use a module loader it will be added to `window.i18nextChainedBackend`
## Backend Options
```js
{
// array of existing i18next backends from https://www.i18next.com/plugins-and-utils.html#backends
backends: [],
// array of options in order of backends above
backendOptions: []
}
```
Options can be passed in:
**preferred** - by setting options.backend in i18next.init:
```js
import i18next from 'i18next';
import Backend from 'i18next-chained-backend';
i18next
.use(Backend)
.init({
backend: options
});
```
on construction:
```js
import Backend from 'i18next-chained-backend';
const Backend = new Backend(null, options);
```
via calling init:
```js
import Backend from 'i18next-chained-backend';
const Backend = new Backend();
Backend.init(null, options);
```
### more complete sample
```js
import i18next from 'i18next';
import Backend from 'i18next-chained-backend';
import Locize from 'i18next-locize-backend'; // load from service
import XHR from 'i18next-xhr-backend'; // have a own xhr fallback
i18next
.use(Backend)
.init({
backend: {
backends: [
Locize, // primary
XHR // fallback
],
backendOptions: [{
projectId: 'myLocizeProjectId'
}, {
loadPath: '/locales/{{lng}}/{{ns}}.json' // xhr load path for my own fallback
}]
}
});
```
