I built a small CDN data path around the S3-compatible contract shared by AWS S3, Cloudflare R2, and MinIO to explore cache identity, request collapsing, revalidation, byte ranges, and the line between a caching proxy and a CDN.
Once integrations become business-critical, the work is no longer just calling APIs. Reliable integration systems need boundaries, state, failure handling, idempotency, observability, operations, and auditability.
External systems do not fail only during outages. They drift, evolve, and quietly violate the assumptions your product has turned into invariants.
API documentation gets you to the first request. Real integration engineering starts when your system has to own the boundary between external behavior and internal meaning.
Technical debt can be the cost of learning, growth, and product success before the architecture catches up.
ReactJS ecosystem has become huge since Facebook made the API public. More so, great libraries have been built in the declarative style adopted by React. However, real life applications require making AJAX requests to servers. And this can pose a great challenge while using React. You need to know what library to use for your AJAX processes.
