feat(firebase): add support for 2nd generation functions

[posva]

🔗 Linked issue

Forked from #1142

Resolves #1141
Resolves #666
Resolves #90

This PR adds a fireabse.gen option instead of firebase.v2 of the original PR to allow customizing gen 2 and gen 1 functions. It also allows passing other options for the functions. This assumes you are only using one generation at the same time (which, outside of migrations should be the case).

@JamieCurnow It was really hard for me to create a code review with all of this so I created a fork of your PR while keeping all the commits. Let me know what you think 🙂

[JamieCurnow]

@posva I've made a PR to your branch on your fork with the suggestions above:
posva#1

Hopefully this is the best way to do this? 😅

Thanks for quick PR @JamieCurnow and all followup ❤️

Let's hope we get out of this situation soon and keep improving preset directly on one main branch 😅

PS: I have sent you an email regarding to join discord server to collaborate closely.

@posva Just adding some of the suggestions from @pi0 here. I've realised that we need to also update the doc changes now to account for the gen selection and to note that the node version can be pinned via the new nodeVersion key. I'm happy to make these changes - may be easier to add me as a collaborator to your fork? Otherwise, let me know and I'll make a PR to your fork again if you want me to jump on this 🙏

[pi0]

Thanks you all for contributing on this preset ❤️ It looks amazing! To move forward i have made some minor refactors as well as docs update about development. Feel free to try it and make PRs directly into the main branch.

BTW we also need to add local tests

Hi!
I see in the Nitro docs the new 2nd gen functions, region and node version.
is it released?

Thx!!

Hi dear @snsxn. you can try with edge channel: https://nitro.unjs.io/guide/getting-started#edge-release-channel

when running firebase emulator it seems is missing region parameter.

Here is the suggestion which could help:

FirebaseFunctions.instanceFor(region: 'europe-west2').useFunctionsEmulator('localhost', 5001);
