Debugging REST APIs

Debugging is an integral part of the development process, especially when working with complex systems like REST APIs in NestJS. A well-thought-out debugging strategy not only helps in quickly identifying the root causes of issues but also ensures that the APIs remain reliable and performant. In this section, we’ll explore various techniques and tools that can significantly enhance your debugging efficiency.

Understanding the issue

The first step in debugging is to accurately understand the problem. This involves gathering as much information as possible about the issue, including error messages, request logs, and the conditions under which the issue occurs. NestJS provides built-in support for logging that can be leveraged to capture detailed information about each request and its outcome.

While NestJS has its logging mechanism, you might find it beneficial to implement custom logging for more detailed insights, especially for capturing request...
