Package Exports

rollup-plugin-external-globals

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (rollup-plugin-external-globals) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

rollup-plugin-external-globals

Transform external imports into global variables like Rollup's output.globals option. See rollup/rollup#2374

Installation

npm install -D rollup-plugin-external-globals

Usage

import externalGlobals from "rollup-plugin-external-globals";

export default {
  input: ["entry.js"],
  output: {
    dir: "dist",
    format: "es"
  },
  plugins: [
    externalGlobals({
      jquery: "$"
    })
  ]
};

The above config transforms

import jq from "jquery";

console.log(jq(".test"));

into

console.log($(".test"));

Note that this plugin only works with import/export syntax. If you are using a module loader transformer e.g. rollup-plugin-commonjs, you have to put this plugin after the transformer plugin.

API

This module exports a single function.

createPlugin

const plugin = createPlugin(
  globals: Object,
  {
    include?: Array,
    exclude?: Array
  } = {}
);

globals is a moduleId/variableName map. For example, to map jquery module to $:

{
  jquery: "$"
}

include is an array of glob patterns. If defined, only matched files would be transformed.

exclude is an array of glob patterns. Matched files would not be transformed.

Virtual modules are always transformed.
