Kopi Error Handler

This library is used to save time for reimplementing express not found and error handler, along with a nice and pretty method to return an error response with a proper error structure.

Installation

Using npm: npm install --save kopi-error-handler

Usage (express)

const KopiErrorHandler = require('kopi-error-handler');

const app = express();
app.use((req, res, next) => KopiErrorHandler.handleNotFound(req, res, next));
app.use((error, req, res, next) => KopiErrorHandler.handleError(error, req, res, next));

Usage (create a custom error)

const KopiErrorHandler = require('kopi-error-handler');

const error = KopiErrorHandler.create({
  code: 404,
  status: 'Not Found',
  message: 'custom message',
  data: { someKey: 'some value' },
  stackTrace: true,
});
throw error;
