Resolving The Unhandled Or The Uncaught Exceptions In Node. js Program

When developing games and applications for specific clients and you are using Node.js program, you will surely face issues like uncaught exceptions or the unhandled exceptions. This program only runs or activates on a single process. Because Node.js runs a pattern like call backs, it is not less common to experience popular errors when developing an application.

How do you resolve unhandled exceptions in a Node.js program?

Upon resolving such kinds of errors in a Node.js program, you should always bear in mind that there are plenty of factors that have affected your program that’s why it failed. You should dig deep into the codes and check them out, here are some ways to resolve errors in a Node.js program:

• Try creating a log file first. If you have entered the codes correctly but you still got an ENOENT error, maybe you just need to create a log file first because maybe it is just the first time you logged in.
• Just let it crash. You will not resolve any errors if you didn’t try it at the first place right? Let it crash and when it failed, try to figure out the codes and parts that need improvement so the application will definitely function on the next time you try it.
• Restart your application. When nothing really worked out, restart your application and then check if there are still bugs, errors, and unhandled exceptions floating around your lines of codes. Nodes can redirect you to STERR which you can use at a later time to figure out the errors on your Node.js program.
• Let domains handle the errors. Upon using domains to resolve unhandled exceptions in a Node.js program, they can help fire away those errors and will help automatically (not all the time) clear out bugs. In Node 0.8, domains are the more sophisticated way to handle exceptions.
• Blow up. I mean it. When it seems that nothing will really happen for the next coding actions you’ll do, just delete the codes. Maybe all you need is to freshen up and start again from scratch to make your application free from errors and any unhandled exceptions.
