Loading node_modules with import/require

nabetti1720 commented 4 days ago

We know that bundling is better for performance, but for experimental or less performance-intensive use cases, it would be great if node_modules loading could be supported.

// index4.js
import { Event } from "event-target-shim";

globalThis.Event = Event

import { Bench } from 'tinybench';

const bench = new Bench({ time: 100 });

import mod from '../package.json';

bench
  .add('json', async () => {
    JSON.stringify(mod)
  })
await bench.warmup();
await bench.run();
console.log(bench.table());

% llrt ./src/index4.js
ReferenceError: Error resolving module 'event-target-shim' from './src/index4.js'

Resolve is very complex, for reference:

Yes, agree that this is super useful but also very complex: ESM: https://nodejs.org/api/esm.html#resolution-and-loading-algorithm CJS: https://nodejs.org/api/modules.html#all-together

Maybe we should do a basic support that doesn't handle all the edge cases?
