Caching GraphQL is harder than REST. REST uses fixed endpoints. GraphQL uses dynamic queries. This makes caching complex.
You need three main strategies:
โข Persisted Queries: You store query strings on the server. The client sends a hash instead of the full query. This saves bandwidth. โข Automatic Persisted Queries (APQ): The client asks the server if it knows a query hash. If not, the client sends the full query. The server then saves it for next time. โข CDN Caching: You cache responses at the edge. This puts data closer to your users.
How to implement these systems:
Start small. Build a simple version that works first. Do not build for scale you do not need yet. Over-engineering creates problems.
Test everything. Write tests for normal use and failure cases. Use automated testing to catch errors early.
Monitor your production data. Look at performance and error rates. Data tells you if your system works. Do not guess. Use facts.
Break down big problems. Large systems hide complexity. Split your work into small pieces. Each piece should be easy to test.
Keep it simple. Complexity ruins reliability. A simple system is easy to fix and easy to change.
Your plan for this week:
Audit your current system. Find one gap. Pick one small improvement to make now.
Your plan for this month:
Implement that improvement. Measure the result. Tell your team what you learned.
