Using the Fetch API for Asynchronous Requests

Describe how to use the Fetch API for making asynchronous HTTP requests. What are the benefits and potential pitfalls?

#fetch#http#async

Answer

  1. Use fetch() to make network requests, returning a promise that resolves to the Response object.
  2. The API supports promises, enabling easy chaining with .then() for response handling.
  3. Benefits include simplicity and straightforward syntax compared to XMLHttpRequest.
  4. Potential pitfalls:
    • fetch does not reject on HTTP error statuses (4xx, 5xx).
    • Requires an additional check for response.ok to catch such errors.
    • Ensure to handle network errors using catch.
