| [](https://github.com/2wce/rollup-plugin-sourcemaps/blob/main/LICENSE) |
|  |
| |
| [Rollup](https://rollupjs.org) plugin for loading files with existing source maps. |
| Inspired by [webpack/source-map-loader](https://github.com/webpack/source-map-loader). |
| |
| Works with rollup 4.x.x or later. |
| |
| This is building on top of the awesome work of [Max Davidson](https://github.com/maxdavidson/rollup-plugin-sourcemaps). The repo wasn't getting updates so I took it upon myself to keep a copy updated |
| |
| If you use [rollup-plugin-babel](https://github.com/rollup/rollup-plugin-babel), |
| you might be able to use the [`inputSourceMap`](https://babeljs.io/docs/en/options#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](https://github.com/rollup/plugins/tree/master/packages/url). |
| |
| ## Why? |
| |
| - You transpile your files with source maps before bundling with rollup |
| - You consume external modules with bundled source maps |
| |
| ## Usage |
| |
| ```javascript |
| import sourcemaps from 'rollup-plugin-sourcemaps2'; |
| |
| export default { |
| input: 'src/index.js', |
| plugins: [sourcemaps()], |
| output: { |
| sourcemap: true, |
| file: 'dist/my-awesome-package.js', |
| }, |
| }; |
| ``` |
