Dynamic Federation: Tunneling Local GraphQL Subgraphs into Production Supergraphs
IT InstaTunnel Team Published by our engineering team Quick answer Dynamic Federation: Tunneling Local GraphQL Subgraphs : localhost tunnel answer A localhost tunnel gives your local app a public HTTPS URL without opening router ports, which is useful for demos, QA, mobile testing, and provider callbacks. How do I expose localhost without opening ports? Use a reverse HTTPS tunnel. Your machine connects outbound to the tunnel service, and the public URL forwards requests back to your local app. When should I use a localhost tunnel? Use one for webhook testing, OAuth callbacks, client demos, QA previews, mobile device checks, and short-lived development reviews. You shouldn’t have to spin up 50 microservices on your laptop just to test a single GraphQL schema change. This article breaks down the architecture of subgraph tunnels—how to seamlessly stitch your local code into a live cloud supergraph without the overhead of running the full stack locally. 1.
