omg please yes

cc @nodejs/userland-migrations can I have first review on this one

[JakobJingleheimer]

This is a great initial implementation 🙂

I think it would be better to consolidate the config handling into a helper since all axios methods support it.

Blocker: There are some axios config options that are not supported here, and, if present in userland code, the absence of support will surely break that userland code. For instance:

transformResponse I think that can probably just be converted to an initial then() prepended to the outputted fetch?

transformRequest I think this can be handled by merely setting fetch's init.body like body: transformRequest(bodyExpression). That would probably also work for paramsSerializer.

If we don't want to handle those more exotic axios config options initially, I think that's okay, but the migration needs to detect them and abort.

[JakobJingleheimer]

Let's include the axios.request or its location (file.ext:row:col) in the warning output here so the user knows what triggered.

Also, I think maybe these should be console.error instead of warning because part of the migration failed.

I didn't get this

[JakobJingleheimer]

Which part don't you get?

[AugustinMauroy]

@JakobJingleheimer I tried to apply all of your proposal.

But why the ci didn't ran ?

[JakobJingleheimer]

It looks like CI did run?

If not, was this whilst I was fiddling with the repo permissions? (I specifically told you on slack you'd temporarily have read-only permissions for a bit, which means you couldn't do anything other than read within the repo)

it's ran after the merge commit. idk what really happened but it's work now !

it's didn't help since I dunno why windows is doing windows thing

[JakobJingleheimer]

Great tidy!

It's still missing handling for transformRequest, transformResponse, paramsSerializer, etc, which was the blocker before. It needs to either

• support them
• detect them and abort/fail the migration

Doing neither will result in broken userland code.
