supabase-workers-proxy

This codebase is a proof-of-concept for making API requests to Supabase inside of a Cloudflare Workers serverless function.

Supabase's JavaScript client doesn't work directly in Workers without using Webpack's externals feature to replace cross-fetch with the native fetch API in Workers, as seen here.

You can see an example of this API at supabase-workers-proxy.signalnerve.workers.dev:

• supabase-workers-proxy.signalnerve.workers.dev/users: select all users
• supabase-workers-proxy.signalnerve.workers.dev/users/:id: query for a user by id
• supabase-workers-proxy.signalnerve.workers.dev/*: all other requests are redirected to this GitHub project

To deploy your own version, clone or fork the project, replace the account_id value in wrangler.toml with your own, and then set two secrets using wrangler secret put:

• SUPABASE_API_KEY: anon/public key available in your Supabase project's "API settings"
• SUPABASE_URL: RESTful endpoint URL available in your Supabase project's "API settings"

This project is built on TypeScript using itty-router and could easily be extended to provide a RESTful interface to your Supabase data, without needing to expose any API credentials.

Note that support for more advanced features, such as proxying authenticated requests, realtime data, and the rest of the Supabase suite are not currently tested or supported. (would be cool tho - open a ticket!)
