What are some common Express.js errors and how can I fix them?

What are some common errors I might encounter when using Express.js?

Some common errors include 'Cannot find module', '404 Not Found', and '500 Internal Server Error'. Would you like details on any specific error?

Yes, can you explain the 'Cannot find module' error?

The 'Cannot find module' error usually occurs when Node.js can't locate a required module. This can happen if the module isn't installed or if the path is incorrect. You can fix it by ensuring the module is installed via npm or checking the import path.

What about the '404 Not Found' error?

The '404 Not Found' error indicates that the requested resource could not be found. This can happen if the route is not defined or if there's a typo in the URL. Make sure your routes are correctly set up and that the URL is accurate.
