How to do global error handling for NextJS api?

Question

For getting the stack trace of the error and push it to external system such as NewRelic etc. is there a way to configure Global error handler which wraps all the APIs So that making changes to all the APIs (multiple files is not required, DRY principle).

Answer 1

You can create a resusable withErrorHandler high order function to wrap your /api handlers like so :-

import logger from 'some-logger';

const withErrorHandler = (handler) => async (req, res) => {
  try {
    return handler(req, res);
  } catch (error) {
    // logger comes here
    // your return statement based on error
  }
};

Suppose your handler looks like :-

const handler = (req,res) => {
// doing something
}

You can export it like so :-

export default withErrorHandler(handler)
