Strip node: prefix when converting to CJS and target < node14.18

[mattfysh]

A recent release of node-fetch exposed an issue where node:* prefix imports compiled into require() calls are not supported if < node v14.18

node-fetch/node-fetch#1367

Is there a way to check the compile target, and if the target is CJS without node:* prefix support, strip away the prefix?

Thanks Evan! :)

Simple redirect and mark it as external in onResolve callback:

var stripNodeColonPlugin = {
  name: 'strip-node-colon',
  setup({ onResolve, onLoad }) {
    onResolve({ filter: /^node:/ }, args => {
      return { path: args.path.slice('node:'.length), external: true }
    })
  }
}

i was just thinking... what if you transpile:

import fs from 'node:fs'
export const foo = 'bar'

into something like:

// main.cjs

(async () => {
  const { default: fs } = await import('node:fs')
  return { foo: 'bar' }
})()

Everything about ESM is async from the ground up. All imports, top-level await.
This is valid cjs. And cjs can load esm modules too, this node prefix works from 12.20 as long as you use dynamic import
