Usage

Predefined Errors

http-res-errors includes predefined classes for common HTTP status codes.

import { BadRequest } from 'http-res-errors';

throw new BadRequest(`That doesn't work`);

Custom Errors

You can use the base HttpError class to return any status.

import { HttpError } from 'http-res-errors';

throw new HttpError(999, 'Something crazy!');

Middleware

Provide catch and response to HTTP errors with frameworks like ExpressJS.

Note: This works with routes that return a promise, like async functions.

import { catchHttpErrors, UnprocessableEntity } from 'http-res-errors';

app.use(catchHttpErrors);

app.get('/', async (res, req) => {
  if (!res.user) {
    throw new Unauthorized('Nice try');
  }

  // ...
});

Development

npm install
npm run build
