How can I debug my Node.js Express application effectively?
You can use several methods to debug your Node.js Express app, such as using console.log, the Node.js debugger, or tools like Visual Studio Code.
What are the advantages of using the Node.js debugger?
The Node.js debugger allows you to set breakpoints, step through code, and inspect variables, making it easier to identify issues.
Can you explain how to set up breakpoints in Visual Studio Code?
Sure! In Visual Studio Code, you can set breakpoints by clicking in the gutter next to the line numbers. Then, start debugging by selecting 'Run' > 'Start Debugging'.
Are there any specific middleware I should use for better error handling?
Yes, using middleware like 'express-async-errors' can help catch errors in asynchronous routes, and you can also create custom error-handling middleware.
