Better way to deal with express error handling. The right way to deal with async errors
npm install express-zonejs-errorsYou are probably wondering...
Why oh why would I need to use a middleware to help me deal with exceptions in my code?
To understand this fundemental yet very important question we must understand 2 important things:
- How node.js deals with exceptions
- How express deals with exceptions
Simple answer: Node will terminate the process when there is an uncaught exception.
The exception can be in our sync code or in our async code node will terminate the process.
Only exception is a rejected promise which node will dismiss with a warning and an additional deperecation message that this will also terminate the process in the future.
