default TRPCError, try/catch & dealing with DatabaseErrors
Hi there!
I'm quite new to tRPC and was hoping that someone could help me out with some general questions related to errors and errorhandling. Thanks in advance!
1. Default TRPCError
It seems like that the fallback / default error that is thrown from the trpc server is a TRPCError with code
INTERNAL_SERVER_ERROR - is this correct?
2. try/catch
If the above is true, I guess in some cases I don't even need to use a try...catch block?
Let's say I'm not checking any specific database errors or anything - then I could leave out try...catch all together - or is it considered a best practice to always just use try...catch for consistency when dealing with async operations, and then throw an INTERNAL_SERVER_ERROR manually?
3. Handling database errors
To combat the above try...catch consistency dillema, I'm thinking about implementing a general errorHandler that handles various database errors thrown by my postgres db.
This handler can then throw specific TRPCErrors depending on the the postgres errors. Additionally, I could extend the TRPCError class to include a translation string for my frontend.
Does this approach sound reasonable?0 Replies
