Import Map Webpack Plugin will produce an import-map of built files.

Usage

const { ImportMapWebpackPlugin } = require("@hackney/webpack-import-map-plugin");

const webpackConfig = {
  entry: {
    main: "./src/index.js",
  },
  output: {
    filename: "[name].[contenthash:8].js",
  },
  plugins: [
    new ImportMapWebpackPlugin({
      basePath: process.env.CDN_URL || "http://localhost:8000",
      namespace: "@mtfh",
      outputFilename: `import-map.${process.env.APP_ENV || "development"}`,
    }),
  ],
};

The above will produce an import-map with the following output:

// dist/import-map.development.json
{
  "imports": {
    "@mtfh/main": "http://localhost:8000/main.74284023.js"
  }
}
