babel-plugin-syntax-hermes-parser

Hermes parser plugin for Babel. This plugin switches Babel to use hermes-parser instead of the @babel/parser. Since Hermes parser uses C++ compiled to WASM it is significantly faster and provides full syntax support for Flow.

Install

Using npm:

``sh
npm install --save-dev babel-plugin-syntax-hermes-parser
`

or using yarn:

`sh
yarn add babel-plugin-syntax-hermes-parser --dev
`

Usage

The plugin can be enabled via:

`
// babel.config.json
{
"plugins": ["babel-plugin-syntax-hermes-parser"]
}
`

If parser options need to be provide you can do so via the parserOpts config:

`
// babel.config.json
{
"plugins": ["babel-plugin-syntax-hermes-parser"],
"parserOpts": {
"allowReturnOutsideFunction": true
}
}
