Linear and github dashboard without express server
Internal tools BFF with zero Node hosting
Frontend / Web apps hit CORS and credential limits when calling Linear and GitHub. Parallel Linear and GitHub steps without Docker or Express. Use one RealComposer edge URL with OPTIONS handling, client tokens, and vault injection.
Why Linear and github dashboard without express server is hard without an edge proxy
Calling Linear and GitHub directly from Frontend / Web risks leaked secrets, CORS blocks, or oversized JSON that slows rendering.
- Exposed API keys in Frontend / Web 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 LINEAR_API_KEY, GITHUB_TOKEN in RealComposer.
Configure edge pipeline
Add upstream steps with vault header injection and map the response fields your client needs.
Call from Frontend / Web
Use your workspace edge URL with a restricted client token.
const res = await fetch('https://realcomposer.com/v1/workspace/linear-github-dashboard-without-express', {
headers: { Authorization: 'Bearer rc_live_client_token' }
});
const data = await res.json();

Developer Questions & Troubleshooting
Is it safe to call Linear from Frontend / Web?
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.
