Error handling

The application uses Winston to log errors. Uncaught errors are logged and handled by the global error handlers.

Error formatting

The application implements a custom error formatter to help when debugging application logs. The error formatter takes a single options argument with the following properties:

Property	Type	Description
cause	Error	A javascript Error object
message	string	A custom message to give context to the error
statusCode	number	A valid HTTP status code indicating the reason for the error

An example of using the error formatter in a middleware function:

const { wrapError } = require('./errors')

const myMiddleware = (req, res, next) => {
  try {
    someOperationThatMightFail()
  } catch (error) {
    return next(wrapError({
      cause: error,
      message: 'Error performing my operation that could fail',
      statusCode: 500
    }))
  }
  return next()
}
