What is babel-preset-env?

babel-preset-env is a smart preset that allows you to use the latest JavaScript without needing to micromanage which syntax transforms (and optionally, browser polyfills) are needed by your target environment(s). It automatically determines the Babel plugins and polyfills you need based on your supported environments.

What are babel-preset-env's main functionalities?

Automatic Polyfilling

Automatically includes polyfills for the features you use based on your target environments. The 'useBuiltIns' option set to 'usage' ensures that only the necessary polyfills are included.

{
  "presets": [
    [
      "@babel/preset-env",
      {
        "useBuiltIns": "usage",
        "corejs": 3
      }
    ]
  ]
}

Targeting Specific Environments

Allows you to specify the environments you want to support. The 'targets' option lets you define the browsers or Node.js versions you want to transpile your code for.

{
  "presets": [
    [
      "@babel/preset-env",
      {
        "targets": {
          "browsers": [
            "> 1%",
            "last 2 versions",
            "not ie <= 8"
          ]
        }
      }
    ]
  ]
}

Debugging

Enables debug mode to print useful information about the targets and plugins being used. This helps in understanding what transformations are being applied.

{
  "presets": [
    [
      "@babel/preset-env",
      {
        "debug": true
      }
    ]
  ]
}
