Pamela Chia 43bacd2f70 fix(www): use service role key for LWX edge function storage uploads (#46411)
## Summary

The three LWX edge functions consume `MISC_USE_ANON_KEY` while their
inline comments claim "SERVICE ROLE KEY": a copy-paste bug. This PR
swaps them to `MISC_USE_SERVICE_ROLE_KEY`, matching `lw11-og` (the
reference implementation that already uses the service role pattern
correctly). The secret is already configured on the project. Service
role bypasses RLS, so uploads succeed regardless of bucket policy and
the key is never exposed (edge functions are server-side).

## Changes

- `lwx-ticket/handler.tsx`: swap storage client to use
`MISC_USE_SERVICE_ROLE_KEY`
- `lwx-og/handler.tsx`: swap storage client to use
`MISC_USE_SERVICE_ROLE_KEY`
- `lwx-ticket-og/handler.tsx`: swap storage client to use
`MISC_USE_SERVICE_ROLE_KEY`

## Testing (Vercel preview)

1. Hit an LWX ticket share URL with a Twitterbot UA: `curl -A
'Twitterbot/1.0' '<preview>/launch-week/x/tickets/<username>'` — expect
HTML with OG meta tags, no edge function error.
2. Confirm the storage object got upserted at
`images/lwx/og/<type>/<username>.png` on `obuldanrptloktxcffvn`.
3. Confirm `MISC_USE_SERVICE_ROLE_KEY` is set as an edge function secret
on the project (it already powers `lw11-og`, so it should be).

### Follow-up (separate, manual)

After merge and deploy, the storage policy on the `images` bucket needs
tightening via the dashboard (no migration setup exists for this
project): revoke `INSERT`/`UPDATE`/`DELETE` policies that grant `anon`,
keep `SELECT` public. All legitimate writers (dashboard team uploads,
LWX/LW11 edge functions) use service role and will continue to work.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Kong is a cloud-native API gateway.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
