defensive-api-handling

To handle malformed JSON or HTML error pages from an API in TypeScript, use safe JSON parsing functions that catch parsing exceptions and validate response content types before processing the data.

The best way to prevent fetch requests from hanging indefinitely is to implement fetch with timeouts, which aborts the request and triggers error handling logic if the server does not respond within a specified timeframe.

To automatically retry failed API requests with configurable delays, implement retry logic that re-executes the fetch call upon failure, applying a specified delay between each retry attempt to ensure resilience.

Yes, you can validate API responses to ensure they match expected TypeScript structures by applying type-safe response validation, which uses type guards to verify that the returned data conforms to the required schema.

An error boundary wraps API calls to catch exceptions gracefully, preventing unexpected non-200 status codes or runtime errors from crashing the application while logging the exceptions for debugging.

Your application crashes when a third-party API returns unexpected data formats because standard parsing assumes valid JSON, so implementing defensive API handling with safe parsing and error boundaries is required to maintain stability.
