TS Fetch API
Using Fetch with TypeScript
TypeScript Fetch API types responses with error handling for HTTP.
Introduction to Fetch API in TypeScript
The Fetch API provides a modern way to make HTTP requests in JavaScript and TypeScript. It is built into most modern browsers and allows you to make network requests similar to the old XMLHttpRequest. In this guide, we will explore how to use the Fetch API with TypeScript, taking advantage of type safety.
Basic Fetch Request
The basic syntax for a fetch request in TypeScript is similar to JavaScript. However, TypeScript allows us to define the types of the response, which enhances code safety and readability.
Typing the Response Data
One of the significant benefits of using TypeScript is the ability to define types for the data you expect to receive. This helps catch errors at compile time rather than runtime. Let's assume we are fetching user data and demonstrate how to type the response.
Handling Errors in Fetch Requests
Error handling is crucial when working with HTTP requests. The Fetch API provides a way to handle network errors using promises. In our examples, we use try...catch blocks to handle any errors that may occur during the fetch operation.
