To put babylon into ESTree-compatible mode the new plugin `estree` can be enabled. In this mode the parser will output an AST that is compliant to the specs of [ESTree](https://github.com/estree/estree/) + +We highly recommend everyone who uses babylon outside of babel to use this plugin. This will make it much easier for users to switch between different ESTree-compatible parsers. We so far tested several projects with different parsers and exchanged their parser to babylon and in nearly all cases it worked out of the box. Some other estree-compatible parsers include `acorn`, `esprima`, `espree`, `flow-parser`, etc. + +To enable `estree` mode simply add the plugin in the config: +```json +{ + "plugins": [ "estree" ] +} +``` + +If you want to migrate your project from non-ESTree mode to ESTree, have a look at our [Readme](https://github.com/babel/babylon/#output), where all deviations are mentioned. + +Add a parseExpression public method ([#213](https://github.com/babel/babylon/pull/213)) (jeromew) + +Babylon exports a new function to parse a single expression + +```js +import { parseExpression } from 'babylon'; + +const ast = parseExpression('x || y && z', options); +``` + +The returned AST will only consist of the expression. The options are the same as for `parse()` + +Add startLine option ([#346](https://github.com/babel/babylon/pull/346)) (Raphael Mu) + +A new option was added to babylon allowing to change the initial linenumber for the first line which is usually `1`. +Changing this for example to `100` will make line `1` of the input source to be marked as line `100`, line `2` as `101`, line `3` as `102`, ... + +Function predicate declaration ([#103](https://github.com/babel/babylon/pull/103)) (Panagiotis Vekris) + +Added support for function predicates which flow introduced in version 0.33.0 + +```js +declare function is_number(x: mixed): boolean %checks(typeof x === "number"); +``` + +Allow imports in declare module ([#315](https://github.com/babel/babylon/pull/315)) (Daniel Tschinder) + +Added support for imports within module declarations which flow introduced in version 0.37.0 + +```js +declare module "C" { + import type { DT } from "D"; + declare export type CT = { D: DT }; +} +``` + +### :eyeglasses: Spec Compliance + +Forbid semicolons after decorators in classes ([#352](https://github.com/babel/babylon/pull/352)) (Kevin Gibbons) + +This example now correctly throws an error when there is a semicolon after the decorator: + +```js +class A { +@a; +foo(){} +} +``` + +Keywords are not allowed as local specifier ([#307](https://github.com/babel/babylon/pull/307)) (Daniel Tschinder) + +Using keywords in imports is not allowed anymore: + +```js +import { default } from "foo"; +import { a as debugger } from "foo"; +``` + +Do not allow overwritting of primitive types ([#314](https://github.com/babel/babylon/pull/314)) (Daniel Tschinder) + +In flow it is now forbidden to overwrite the primitive types `"any"`, `"mixed"`, `"empty"`, `"bool"`, `"boolean"`, `"number"`, `"string"`, `"void"` and `"null"` with your own type declaration. + +Disallow import type { type a } from … ([#305](https://github.com/babel/babylon/pull/305)) (Daniel Tschinder) + +The following code now correctly throws an error + +```js +import type { type a } from "foo"; +``` + +Don't parse class properties without initializers when classProperties is disabled and Flow is enabled ([#300](https://github.com/babel/babylon/pull/300)) (Andrew Levine) + +Ensure that you enable the `classProperties` plugin in order to enable correct parsing of class properties.
