External APIs are often unreliable. Between rate limits, network issues, and service outages, failures are bound to happen. In this post, you'll learn how to build more resilient TypeScript API clients using "ts-retry-promise". We cover defensive error handling, smart retry conditions, and how to integrate retries cleanly into your service logic.
Learn how to strengthen your TypeScript applications with Zod, a powerful schema validation library. Discover how Zod enables type-safe, runtime validation with minimal boilerplate, so you can save time and effort when developing API services and data-driven applications.
Learn how to replace traditional try & catch error handling in TypeScript with the safer and more explicit Result Type pattern. This post walks through building a minimal custom Result implementation, explains the benefits of structured error handling, and shows how to adopt the neverthrow library and ESLint configuration.
This article explains how to filter arrays in TypeScript while maintaining correct types. It demonstrates how to create a type guard to ensure that the filtered array only contains the desired type. It also discusses the downsides of type guards and compares them to assertion functions.
