Babel preset for stage 0 plugins


7.2.1-263 years ago3 years agoMinified + gzip package size for @gerhobbelt/babel-preset-stage-0 in KB



As of v7.0.0-beta.55, we've removed Babel's Stage presets. Please consider reading our blog post on this decision for more details. TL;DR is that it's more beneficial in the long run to explicitly add which proposals to use.

For a more automatic migration, we have updated babel-upgrade to do this for you (you can run npx babel-upgrade).

If you want the same configuration as before:

  "plugins": [
    // Stage 0

    // Stage 1
    ["@gerhobbelt/babel-plugin-proposal-optional-chaining", { "loose": false }],
    ["@gerhobbelt/babel-plugin-proposal-pipeline-operator", { "proposal": "minimal" }],
    ["@gerhobbelt/babel-plugin-proposal-nullish-coalescing-operator", { "loose": false }],

    // Stage 2
    ["@gerhobbelt/babel-plugin-proposal-decorators", { "legacy": true }],

    // Stage 3
    ["@gerhobbelt/babel-plugin-proposal-class-properties", { "loose": false }],

If you're using the same configuration across many separate projects, keep in mind that you can also create your own custom presets with whichever plugins and presets you're looking to use.

module.exports = function() {
  return {
    plugins: [
      [require("@gerhobbelt/babel-plugin-proposal-decorators"), { "legacy": true }],
      [require("@gerhobbelt/babel-plugin-proposal-class-properties"), { "loose": false }],
    presets: [
      // ...
