most React developers don't know why their promises break silently. they wrap everything in .catch() and wonder why errors still slip through. the problem: - .catch() only catches errors up to that point - errors after the chain slip through unhandled - processData() throws but catch doesn't see it the fix : check response status: and one rule: proper error boundaries. check status. validate data. catch at the end. #reactjs #typescript #webdevelopment #buildinpublic #javascript
Clear explanation 👏 . API integration is not about integrating with endpoint. Every single API integration need to check with 200 / 500 / 404 / 401 Error status. Most importantly It need to validated with network throttle.
Great post! Understanding promise chaining, especially how errors propagate, is key. It’s also important to understand how error handling differs between promise chains and async/await, since the control flow can change how errors are caught and handled.
Good point, but slightly off. .catch() isn’t the problem—fetch not rejecting on HTTP errors is. Always check res.ok and keep error handling consistent.
