[Replacement]: replace form-data with native FormData (and fetch)

[tbroyer]

Package to replace

form-data

Suggested replacement(s)

In many (if not most) cases, the native FormData (https://nodejs.org/docs/latest/api/globals.html#class-formdata, https://developer.mozilla.org/en-US/docs/Web/API/FormData) could be used instead with no change.

There are some usages of the form-data library that require some code changes though:

• using streams or directly a Buffer: those need to be turned into a Blob (possibly through node:stream/consumers)
• the submit() method: can be replaced with fetch()
• a few other specific methods that might not all have replacements (e.g. getBoundary/setBoundary)

Manifest type

native (replaceable by a built-in platform feature)

Rationale

The package mostly duplicates the native FormData

Availability

Node v18 without flags, v21 as non-experimental.
In browsers for 14 years!

Code example (optional)

makes sense 👍

we should probably see what the common usage is and show that in our migration doc
