FormData

[ronag]

Support for form data in fetch.

Do we know of any spec compliant implementation that we can re-use?

This is the library node-fetch uses: https://github.com/form-data/form-data

[Ethan-Arrowood]

There is also this on going discussion for form-data in node core: nodejs/node#38943

@Ethan-Arrowood That library uses combined-stream which is not maintained anymore has lots of bugs and we have problems with it in Got :(

[szmarczak]

Maybe @octet-stream would be interested in this. Relevant: sindresorhus/got#1810

There's at least two spec-compliant implementations for Node.js: formdata-node which has some additional APIs that are not spec-compliant, but I'm planning to get rid of them in the next major release around Node.js 12 EOL, and we also have formdata-polyfill

I also have made an encoder that can be used for multipart/form-data serialization: form-data-encoder

[octet-stream]

By the way, node-fetch has a plan to remove support of form-data package. See: node-fetch/node-fetch#1167

Not sure if spec compliant, but we've got great results with https://www.npmjs.com/package/multi-part.

We have used it with both got and undici.

[szmarczak]

unmaintained :(

Doesn't look too difficult to implement ourselves both FormData and File look rather trivial. @Ethan-Arrowood or @szmarczak would you be interested to have a go at it?
