Migrate to ECMAScript modules

[0x2b3bfa0]

We're using CommonJS modules instead of ECMAScript modules, but most of our dependencies are already using the latter. Let's consider migrating and then transpile our code back to CommonJS when needed, e.g. when using pkg to produce standalone binaries.

Dependents

• No native git dependency #1003
• Integrate cml publish with cml send-comment #1026 not anymore

Related

• Drop support for Node.js 12 or use a transpiler #597

Blockers

• feat: ESM modules support vercel/pkg#1323

[0x2b3bfa0]

After several¹ hours of research, I've come to the conclusion that the easiest “solution” for #1026 is downgrading dependencies to the latest CJS version available. 🙈 See 484143d..e78bbec for some failed attempts at packaging ESM binaries.

Mid-term solutions

• Wait for feat: ESM modules support vercel/pkg#1323
• Wait for bootstrap: implement run-time user-land snapshots via --build-snapshot and --snapshot-blob nodejs/node#38905 (comment).

@0x2b3bfa0 should we keep this around after the latest comments: vercel/pkg#1323 (comment)

This feels like an icebox item to me

Vercel's pkg is no longer relevant after #1051 (comment). I'd consider revisiting this eventually, but icebox is fine for now. 👍🏼
