    rollup-plugin-uglify Travis Build Status

    Rollup plugin to minify generated bundle. Uses UglifyJS under the hood. There are a few improvements over native uglify:

    • uglify is run in worker for every chunk
    • errors are displayed with babel code frame

    Note: uglify-js is able to transpile only es5 syntax. If you want to transpile es6+ syntax use terser instead

    Install

    yarn add rollup-plugin-uglify --dev

    Note: this package requires rollup@0.66 and higher

    Usage

    import { rollup } from "rollup";
    import { uglify } from "rollup-plugin-uglify";
     
    rollup({
      input: "main.js",
      plugins: [uglify()]
    });

    Options

    uglify(options);

    options - uglifyJS API options

    options.sourcemap: boolean

    Generates source maps and passes them to rollup. Defaults to true.

    options.numWorkers: number

    Amount of workers to spawn. Defaults to the number of CPUs minus 1.

    Examples

    Comments

    If you'd like to preserve comments (for licensing for example), then you can specify a function to do this like so:

    uglify({
      output: {
        comments: function(node, comment) {
          if (comment.type === "comment2") {
            // multiline comment
            return /@preserve|@license|@cc_on/i.test(comment.value);
          }
          return false;
        }
      }
    });

    Alternatively, you can also choose to keep all comments (e.g. if a licensing header has already been prepended by a previous rollup plugin):

    uglify({
      output: {
        comments: "all"
      }
    });

    See UglifyJS documentation for further reference.
