A wepback plugin to verify ECMAScript version for bundle files.

This plugin is intended to verify that bundle files don't include unsupported syntaxes, so I encourage to enable this only on a production build.

% npm install --save-dev ecma-version-validator-webpack-plugin

Add a ECMAVersionValidatorPlugin instance into a plugins field in webpack.config.js

• webpack.config.js

const { ECMAVersionValidatorPlugin } = require("ecma-version-validator-webpack-plugin");

module.exports = {
    // ...
    plugins: [
      new ECMAVersionValidatorPlugin(/* options */)
    ],
}

• options.ecmaVersion
  • This is a target ECMAScript version you expect. See the avaiable versions in the Acorn's documentation. The default version is 5(ES5).
• options.test
  • A RegExp pattern to apply this plugin. The default value is /\.(m)?js$/.
