Public tRPC query endpoints often lack proper caching, leading to increased server load and slower response times for users.
Enable caching for all public tRPC queries by configuring responseMeta in the server setup.
High-intent search queries and answers about installing and using this skill.
Configure responseMeta callbacks in your tRPC server setup to apply Cache-Control, s-maxage, and stale-while-revalidate headers on successful public query routes, enabling CDN and browser caching.
The safest way to prevent caching authenticated tRPC requests is to configure responseMeta to explicitly skip applying Cache-Control headers for authenticated requests, errors, and mutations, preventing sensitive data leakage.
Yes, you can use responseMeta to set Cache-Control headers with tRPC fetch adapters. The caching configuration works flexibly with both @trpc/server standalone and fetch adapters for public query routes.
Stale-while-revalidate allows a CDN to serve a cached tRPC response immediately while fetching a fresh version in the background. You configure this via responseMeta callbacks alongside s-maxage directives for public queries.
You should not use HTTP caching on tRPC endpoints handling mutations, returning errors, or serving authenticated user data. Skipping Cache-Control headers on these routes prevents stale data and data leakage issues.
