Babylon is a JavaScript parser used in <a href="https://github.com/babel/babel">Babel</a>.
|
||||
</p>
|
||||
|
||||
- ES6 enabled by default.
|
||||
- Comment attachment.
|
||||
- Support for JSX and Flow.
|
||||
- Support for experimental language proposals.
|
||||
|
||||
## Credits
|
||||
|
||||
Heavily based on [acorn](https://github.com/marijnh/acorn) and [acorn-jsx](https://github.com/RReverser/acorn-jsx),
|
||||
thanks to the awesome work of [@RReverser](https://github.com/RReverser) and [@marijnh](https://github.com/marijnh).
|
||||
|
||||
Significant diversions are expected to occur in the future such as streaming, EBNF definitions, sweet.js integration, interspacial parsing and more.
|
||||
|
||||
## API
|
||||
|
||||
### `babylon.parse(code, [options])`
|
||||
|
||||
## Options
|
||||
|
||||
- **allowImportExportEverywhere**: By default, `import` and `export`
|
||||
declarations can only appear at a program's top level. Setting this
|
||||
option to `true` allows them anywhere where a statement is allowed.
|
||||
|
||||
- **allowReturnOutsideFunction**: By default, a return statement at
|
||||
the top level raises an error. Set this to `true` to accept such
|
||||
code.
|
||||
|
||||
- **allowSuperOutsideMethod** TODO
|
||||
|
||||
- **sourceType**: Indicate the mode the code should be parsed in. Can be
|
||||
either `"script"` or `"module"`.
|
||||
|
||||
- **sourceFilename**: Correlate output AST nodes with their source filename. Useful when generating code and source maps from the ASTs of multiple input files.
|
||||
|
||||
- **plugins**: Array containing the plugins that you want to enable.
|
||||
|
||||
### Example
|
||||
|
||||
```javascript
|
||||
require("babylon").parse("code", {
|
||||
// parse in strict mode and allow module declarations
|
||||
sourceType: "module",
|
||||
|
||||
plugins: [
|
||||
// enable experimental async functions
|
||||
"asyncFunctions",
|
||||
|
||||
// enable jsx and flow syntax
|
||||
"jsx",
|
||||
"flow"
|
||||
]
|
||||
});
|
||||
```
|
||||
|
||||
### Plugins
|
||||
|
||||
- `jsx`
|
||||
- `flow`
|
||||
- `asyncFunctions`
|
||||
- `classConstructorCall`
|
||||
- `doExpressions`
|
||||
- `trailingFunctionCommas`
|
||||
- `objectRestSpread`
|
||||
- `decorators`
|
||||
- `classProperties`
|
||||
- `exportExtensions`
|
||||
- `exponentiationOperator`
|
||||
- `asyncGenerators`
|
||||
- `functionBind`
|
||||
- `functionSent`
