Tracking: Replacing polyfill dependencies with node.js native APIs

[jasnell]

Just opening this as a way of tracking which polyfill dependencies can soon be replaced with official node.js apis...

• @mrbbot/node-fetch --> https://github.com/nodejs/undici
• @peculiar/webcrypto --> Node.js core WebCrypto impl
• event-target-shim --> Node.js core EventTarget impl
• formdata-node --> We should implement FormData in Node.js core
• web-streams-polyfill --> Node.js core Web Streams impl

Nice! 🎉 Thanks for collating these all together.

Lots of these have been implemented in version 2. 🙂

I was planning on making Node 16 required for the next major version which should be released around the same time it becomes the Active LTS. Was considering making a @miniflare/compat package that hooked into the require of built-ins to replace them with these polyfill dependencies, but I'm not sure the extra maintainence work is worth it, especially as this is primarily a development tool, so the Node version people use should be more flexible.

Hey! 👋 The first pre-release of Miniflare 2 has just been released, which replaces all these polyfill dependencies with the equivalent Node.js native APIs. The full changelog is here and it can be installed with npm i miniflare@next -D.
