    @babel/preset-stage-2

    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 2
        ["@babel/plugin-proposal-decorators", { "legacy": true }],
        "@babel/plugin-proposal-function-sent",
        "@babel/plugin-proposal-export-namespace-from",
        "@babel/plugin-proposal-numeric-separator",
        "@babel/plugin-proposal-throw-expressions",
     
        // Stage 3
        "@babel/plugin-syntax-dynamic-import",
        "@babel/plugin-syntax-import-meta",
        ["@babel/plugin-proposal-class-properties", { "loose": true }],
        "@babel/plugin-proposal-json-strings"
      ]
    }

    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("@babel/plugin-syntax-dynamic-import"),
          [require("@babel/plugin-proposal-decorators"), { "legacy": true }],
          [require("@babel/plugin-proposal-class-properties"), { "loose": false }],
        ],
        presets: [
          // ...
        ],
      };
    };

    NOTE: Compatibility between @babel/plugin-proposal-class-properties and @babel/plugin-proposal-decorators If you are including your plugins manually and using @babel/plugin-proposal-class-properties, make sure that @babel/plugin-proposal-decorators comes before @babel/plugin-proposal-class-properties.

    When using the legacy: true option of @babel/plugin-proposal-decorators, @babel/plugin-proposal-class-properties must be used in loose: true mode.

    If you are not using @babel/plugin-proposal-decorators, loose mode is not needed.
