Combine anthropic with supabase vector rag search
RAG answer pipeline in one call
To combine anthropic with supabase vector rag search, use one RealComposer pipeline with parallel steps. Anthropic completion plus Supabase vector match results composed at edge. Your Next.js / React app makes one request instead of several sequential upstream calls.
Why Combine anthropic with supabase vector rag search is hard without an edge proxy
Calling Anthropic and Supabase directly from Next.js / React risks leaked secrets, CORS blocks, or oversized JSON that slows rendering.
- Exposed API keys in Next.js / React bundles or DevTools
- Sequential upstream calls on slow mobile networks
- Third-party rate limits and surprise billing spikes
How RealComposer Solves This at the Edge
Store credentials in Secret Vault
Save ANTHROPIC_API_KEY, SUPABASE_ANON_KEY in RealComposer.
Configure edge pipeline
Add upstream steps with vault header injection and map the response fields your client needs.
Call from Next.js / React
Use your workspace edge URL with a restricted client token.
const res = await fetch('https://realcomposer.com/v1/workspace/combine-anthropic-supabase-vector-rag', {
headers: { Authorization: 'Bearer rc_live_client_token' }
});
const data = await res.json();

Developer Questions & Troubleshooting
Is it safe to call Anthropic from Next.js / React?
Only if secrets stay off the device. RealComposer injects credentials on the server edge so clients never hold production keys.
Does RealComposer add latency?
Cloudflare edge execution adds a few milliseconds; caching can answer repeat calls in under 10ms.
