Example: esm.dual

Please read /docs/esm for full details & comparisons.

Why

Unlike /examples/esm.loader, this example uses the native ESM loader whenever it's available.

Unlike /examples/esm.mjs, this example will run in all versions of Node.js – including older versions where ESM is not natively supported.

Define "type": "module" within package.json
Allows Node.js to treat .js files as ESM.
Define import statements with full file paths
Required by Node.js whenever ESM in use.
Define two test scripts:
- "test:native" – for use within Node 12+
- "test:legacy" – for use with Node < 12
