How APIs Use HTTP Caching to Reduce Latency

In episode 59 of The API Podcast, Lucas and Luna explore how HTTP caching can dramatically reduce API latency and server load. They dive into the mechanics of Cache-Control headers, ETags, and conditional requests, using the real-world example of how GitHub's API cut response times by over 60% by implementing smart caching. The hosts discuss the difference between private and public caches, the role of CDNs, and common pitfalls like cache invalidation. They also touch on how GraphQL complicates caching and what tools like Apollo Client do to work around it. By the end, you'll understand why caching is often the single most impactful optimization for API performance. No fluff, just practical details you can apply to your own APIs. #HTTPCaching #APILatency #CacheControl #ETags #ConditionalRequests #GitHubAPI #CDN #ApolloClient #GraphQLCaching #APIoptimization #WebPerformance #RESTAPI #CacheInvalidation #Technology #FexingoBusiness #BusinessPodcast #WebAPIs #SoftwareEngineering Keep every episode free: buymeacoffee.com/fexingo
