How Do I Debug JavaScript Network Requests Using The Network Tab? Have you ever wondered how developers troubleshoot network requests made by JavaScript in web applications? In this informative video, we'll explain everything you need to know about debugging JavaScript network requests using browser developer tools. We'll start by showing how to access the network tab and what types of network activities it records, including API calls and resource loads. You'll learn how to filter requests to focus on asynchronous operations like Fetch API and XMLHttpRequest, making it easier to identify issues. We'll also demonstrate how to inspect request details such as headers, payloads, responses, and timing information, which helps pinpoint slow or failed requests. Additionally, you'll discover how to resend requests with "Replay XHR" and "Copy as fetch" options to test different server responses quickly. The video covers how to interpret status codes, trace requests back to the source code, and export network data for further analysis. We’ll also discuss how to simulate slow network conditions to test your app’s performance under different scenarios. Whether you're debugging data fetching, handling errors, or optimizing performance, mastering the network tab is an essential skill for web developers.
