📚 Description

Related to discussions #110 #196, a few in nuxt/framework

This PR intends to add a preset for Cloudflare Pages Functions - which is currently in Open Beta. Docs can be found at https://developers.cloudflare.com/pages/platform/functions/ .

Pages Functions are based on the modules worker type, so a different deployment preset will be needed.

update since first drafted, removed no longer relevant beta warnings

Functions are still in beta, however Direct Upload is now available for Pages, and I fixed all the issues I could find.

update again

Docs have now been updated (feedback welcome), the newest version of std-env should allow for automatic detection (only via git integration).

Have a good day.

Hey @DaniFoldi 👋

Do you need help to test / finish this one?

I'm currently investigating to migrate to Cloudflare pages and I require this preset.

[DaniFoldi]

Hi!

I started writing the docs for the preset earlier today, so it should be ready today or tomorrow - the one remaining thing after this PR will be figuring out how to give api routes the request context.

@tuarrep I believe it's ready for testing, and feel free to leave any feedback on the docs as well. (vercel had a problem deploying, but doesn't tell what the problem was, so if it's something that I messed up (probably) could someone with access let me know?

does this mean by adding ./server/api/function.js and with git integration the preset will be auto set as cloudflare_pages, and the /function directory will be created with the function.js api? I have tested it here, and while the function folder is created, no function is actually deployed on cloudflare network . Tried running CF_PAGES=1 npm run generate in this stackblitz terminal https://stackblitz.com/edit/github-dxg5qg?file=server%2Fapi%2Fcustomer.get.js

Updated : Changed cloudflare build settings to npm run build , this does seem to pick up the /server/api/[routes] and inject them into /functions/[[path]].js However, for some reasons only GET requests are working, POST requests are getting 405 Method not allowed -- anyone else have better results?

Seeing same issue with non-get requests returning 405
