How the logger works for errorhandling?

[Atomzwieback]

If i do a transaction there could sometimes happen an error but i dont know how to handle them without crashing my application due it not got catched by try/catch. I saw there is a logger from etherjs does this helps me to catch and log the error without crashing the app? If yes how to use it?

The logger just handles making sure all ethers errors conform to the same format. All errors in ethers have an error.code property which matches one of the error codes.

All errors should be catchable in the standard ways. For Promise-based things, either using await in the try block or using the .catch method are needed, but all synchronous errors just need a try..catch.

If you have a code example where you are unable to catch the error, let me know.
