rollup-plugin-rewrite-imports v2.0.0

rollup-plugin-rewrite-imports

Pass a string in to rewrite the path of ES module imports and dynamic imports if the dependency already exists in a separate node_modules directory.

Why

This is useful when you have fragmented or disconnected build routines. This can happen when part of 1 application is modularly mixed with another at run time. HAXcms leverages this plugin to allow theme developers to use the expeced approaches and methods they typically find in web component development, yet not break the site given that the build routine is shipped with that system.

This puts theme developers and platform owners on the same tooling / workflows yet work independently of one another.

Install

$ npm install rollup-plugin-rewrite-imports --save-dev

or

$ yarn add rollup-plugin-rewrite-imports --dev

How to use

rewriteImports is called in order to forcibly point to the location that we are actually building these assets into.

const path = require("path");
const autoExternal = require("rollup-plugin-auto-external");
const rewriteImports = require("rollup-plugin-rewrite-imports");
const production = true;
module.exports = function() {
  return {
    input: "src/custom.js",
    treeshake: !!production,
    output: {
      file: `build/custom.amd.js`,
      format: "esm",
      sourcemap: false
    },
    plugins: [
      rewriteImports(`../../build/es6/node_modules/`)
    ]
  };
};
