# tRPC -- Error Handling

Make tRPC failures clear to the client and easy to trace

## What this does

When a call to your tRPC server fails, the person on the other end needs to know why, and you need to see it happen. This helps you throw errors with a clear code such as not found or unauthorized, shape how validation errors reach the client, handle all errors in one spot, and turn them into matching HTTP status codes.

### Top 3 things it does for you

- Throw an error that says what went wrong
- Show validation errors on the client
- Catch every server error in one place

## About tRPC -- Error Handling

This covers throwing typed errors with TRPCError and error codes such as NOT_FOUND, UNAUTHORIZED, BAD_REQUEST and INTERNAL_SERVER_ERROR.

It configures an errorFormatter so Zod errors can be displayed on the client, handles errors globally with an onError callback, and maps tRPC errors to HTTP status codes with getHTTPStatusCodeFromError().
