babel-preset-runtime

Extending @babel/preset-env

Usage

First, install Babel.

Then install babel-preset-rutime.

    # npm
    npm install babel-preset-rutime

    # yarn
    yarn add babel-preset-rutime

Then create a file named .babelrc or babel.config with following contents in the root folder of your project:

{
	"presets": ["babel-preset-rutime"]
}

Default configs of babel-preset-rutime

//  @babel/preset-env
{
	"useBuiltIns": "entry",
	"corejs": 3,
	"exclude": ["transform-typeof-symbol"]
}
// @babel/plugin-transform-runtime
{
    corejs: false,
    helpers: true,
    version: require("@babel/runtime/package.json").version,
    regenerator: true,
    absoluteRuntime: path.dirname(
			require.resolve("@babel/runtime/package.json")
		),
}

You can fully override default config

{
	"presets": [
		[
			"babel-preset-rutime",
			{
				//options of  @babel/preset-env
				"env": {},
				//options of @babel/plugin-transform-runtime
				"runtime": {}
			}
		]
	]
}

				"react": {}
