Errors

Errors exposed in this package extends the Error class, and have a status property containing the HTTP equivalent status. The error message defaults to a description of the HTTP status.

example

if (!product) {
  throw new NotFoundError('Product not found');
}

results in

[404] {
  "type": "NotFoundError",
  "message": "Product not found"
}

Middlewares

• The middleware notFoundMiddleware will handle the error and respond to the request in a standardized way.

• The notFoundMiddleware middleware will respond to all routes that are not specified

To use in an express application, register the middlewares after the routes:

import Express from 'express';
import { errorHandler, notFoundMiddleware } from '@colussi/errors';

const app = new Express();

app.use(...); // your routes

app.use(errorHandler);
app.all('*', notFoundMiddleware);
