rollup-plugin-sourcemaps2

Rollup plugin for loading files with existing source maps. Inspired by webpack/source-map-loader.

Works with rollup 4.x.x or later.

This is building on top of the awesome work of Max Davidson. The repo wasn't getting updates so I took it upon myself to keep a copy updated

If you use rollup-plugin-babel, you might be able to use the inputSourceMap option instead of this plugin. Conversely, if you use this plugin alongside rollup-plugin-babel, you should explicitly set the Babel inputSourceMap option to false.

If this plugin is not resolving the sourcemap URL (particularly on MS Windows), try also including the official rollup plugin @rollup/plugin-url.

Why?

• You transpile your files with source maps before bundling with rollup
• You consume external modules with bundled source maps

Usage

import sourcemaps from 'rollup-plugin-sourcemaps2';

export default {
  input: 'src/index.js',
  plugins: [sourcemaps()],
  output: {
    sourcemap: true,
    file: 'dist/my-awesome-package.js',
  },
};
