Chapter 1: Introduction to Chrome's Developer Tools

In a recent announcement, Addy Osmani, a leading engineer at Google, highlighted a significant enhancement in the latest version of the Chrome browser.

As he noted, with Chrome 117, developers can now modify the content of Fetch and XHR requests, including their response headers. This functionality is particularly beneficial for simulating API responses during debugging, eliminating the need to wait for backend or API adjustments.

With this new capability, developers can directly alter the responses of live API calls right in their browser.

This feature proves invaluable; for instance, if the backend team introduces an error in a response, you can temporarily correct it in the browser for integration testing. Additionally, you can simulate various responses to evaluate how your application reacts.

Stay tuned for more updates!

Such tools greatly enhance debugging and accelerate the development process, allowing developers to avoid the lengthy task of creating mocks or proxies for APIs.

Jacelyn Yeen is the talented engineer responsible for this and several other upcoming features.

If you're eager to try this new option, consider downloading Chrome Canary. You can witness its functionality in the following video:
