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

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

try...catch

block?
Let's say I'm not checking any specific database errors or anything - then I could leave out

try...catch

try...catch

all together - or is it considered a best practice to always just use

try...catch

try...catch

for consistency when dealing with async operations, and then throw an

INTERNAL_SERVER_ERROR

INTERNAL_SERVER_ERROR

manually?

3. Handling database errors
To combat the above

try...catch

try...catch

consistency dillema, I'm thinking about implementing a general

errorHandler

errorHandler

that handles various database errors thrown by my postgres db.
This handler can then throw specific

TRPCErrors

TRPCErrors

depending on the the postgres errors. Additionally, I could extend the

TRPCError

TRPCError

class to include a translation string for my frontend.

Does this approach sound reasonable?
