@node-loader/import-maps

node-import-map-loader

A nodejs loader for import maps. This allows you to customize module resolution by creating a node.importmap file.

Installation

npm install --save @node-loader/import-maps

# Or, if you prefer Yarn
yarn add --save @node-loader/import-maps

Usage

Create a file node.importmap in the current working directory:

{
  "imports": {
    "my-module": "file:///Users/name/code/my-module.js"
  }
}

Now create a file that imports the mapped module:

import "my-module";

Now run node with the --experimental-loader flag:

node --experimental-loader @node-loader/import-maps file.js

Configuration

The path to your import map may be configured with the IMPORT_MAP_PATH environment variable:

IMPORT_MAP_PATH=/Users/name/some/dir/node.importmap node --experimental-loader @node-loader/import-maps file.js

Composition

If you wish to combine import maps with other NodeJS loaders, you may do so by using node-loader-core.
