What can I use instead of Supabase Edge Functions?
Whats the problem?
- Deno is weird, scale ~hours
- VSCode deno support is not smooth, scale ~hours
- Supabase Edge Functions have had a lot of issues when running locally, ~10 hours
What are the requirements?
- I want to quickly iterate on api endpoints
- I want endpoints behind authentication
- I want to hit OpenAI endpoints
- Currently using Supabase for my managed Postgres database (most writes are client-side right now)
What are the alternatives?
Vercel Edge Functions
- Runtime is V8, aka not Node.js -> so most packages that require node apis will not work
- Max execution time 25 seconds
- Max memory 128 MB
- Code size limit
- Hobby 1 MB
- Pro 2 MB
- Enterprise 4 MB
- Other limits listed here
Evaluation:
- runtime is v limited, for faster iteration I will need to use a different service
Vercel Serverless Functions
- Runtime is Node.js v18 (default)
- Supports Go, Python, Ruby
- Configure max execution time in the function export const maxDuration = 10 // seconds
- Configure max memory in vercel.json "memory": 128 (MB) up to 3008
- Region default is Washington D.C.
- Can be configured in function export const preferredRegion = ['iad', 'lax']
How will I do authentication
Looks like Supabase has good support for this via cookie based auth with a helpful package @supabase/ssr. Lets try it out...
- first note that ssr is a replacement for the old auth-helpers-nextjs package
- lets migrate https://supabase.com/docs/guides/auth/server-side/migrating-to-ssr-from-auth-helpers
- that seems to be sorta working, but when i try to login I get signups not allowed for otp error -> never mind that was becuase I nuked the docker container and forgot to re-make my user
- I wonder how this will all deploy to vercel? now that I turned next.config.js // output: 'export', off...

On the Edge:
But do I even need Edge Functions? Perhaps I would benefit from setting up a simple node app somewhere?
