Find dependencies to transpile with Babel.

webpack-babel-env-deps

Find dependencies to transpile with Babel.

📖 Read the docs!

A webpack helper to find dependencies of your project that require transpilation with Babel (and @babel/preset-env) by comparing your minimum Node.js engine against theirs (engines in package.json), and/or by determining their minimum Node.js engine or published ES2015/ES6+ source (module/jsnext:main in package.json) to require features provided by plugins and polyfills from @babel/preset-env.

webpack-babel-env-deps's Issues

feat: support esnext field in package.json

jest eslint config test overrides

Caching

feat: detect browserslist configs

Detect browserslist config files in dependencies, especially as package.json field (since rest may be npmignored).

Option for default transpile or not

If a package doesn't have enough info (e.g., no engines field), set whether it should transpile by default or not via an option.

Package doesn't show in babelEnvDeps.exclude()

I'm using react-dates, and when I try logging what's available in babelEnvDeps.exclude(), it's not showing up. Is there a way to enforce it?

Here is the error I was getting before I switched from exclude: [babelEnvDeps.exclude()] to exclude: /node_modules/

Error: Couldn't find preset "airbnb" relative to directory

Handle babel env disabled features.

We don't need to transpile certain babel env plugins that are disabled by the user in their Babel env settings.

We could sniff this from user's Babel config.

Or at least provide an option here to manually override considering certain babel env plugins from consideration for transpiling.

feat: function to get module names

We should support a function to just get the array of module names as strings (instead of the constructed regex) for use with something like https://github.com/module-federation/next-transpile-modules.

dist/index.js missing

It seems that in 1.6.0 dist/index.js that is defined in the "main" field in package.json is missing.

ignore nested babelrc

Allow non-semver versions

This error is thrown in my project

Error: Invalid version: "207-alpha1-SNAPSHOT"

Our version in package.json is sentimental, not in semver.

In error stack trace I can see above error comes from

/node_modules/webpack-babel-env-deps/node_modules/read-pkg/index.js:43:36

Not sure if this is related to your package or read-pkg or normalize-package-data. Feel free to close if I'm wrong here. Thanks.

consume babel-preset-env targets for except

This would allow us to except from transpilation any modules that don't meet user-specified minimum targeted node version anyway (https://github.com/babel/babel-preset-env#targetsnode).

We would treat these modules as if they were passed to except on an exclude call - that is, not include them in the whitelist of node modules that is allowed in the regex.

getPluginsThatDontSatisfyModuleRange breaks when "node" missing from definition

export function getPluginsThatDontSatisfyModuleRange(plugins, range) {
  return _.pickBy(
    plugins,
    ({ node }) => !semver.satisfies(normalizeSemver(node), range)
  )
}

assumes that the plugin has a "node" field which proposal-nullish-coalescing-operator does not have. This causes the semver module to throw an error, because "undefined.0.0" is not a valid version.

Option to exclude modules detected only by mainFields

The parameter mainFields should also take boolean false parameter which would disable modules that were detected only by presence of fields such as module or jsnext:main in the package.json.

Many libraries are shipped with both commonjs and es6 builds and thus have these parameters present in package.json. In most cases bundler such as webpack or rollup will pick up proper version of the module and process the source code, so there is no need to additionally transpile it.

By default the packages should be selected only by engines settings in package.json.

Include doesn't work with Windows paths separators like exclude does
