Simple and efficient global errors handler that handle errors of development and production , you don't worry about leaking informations in the production
npm i errors-handler --save
Make sur you have a .env file contain NODE_ENV=development/production
For now i use it for my self , it's very usefull but there is messings errors , so i appreciate your contributions :)
In an Express-based application:
const app = express();
const errorsHandler = require('errors-handler')
const sendError = require('errors-handler/appError');
//don't work without .env with variable NODE_ENV=production/development
require('dotenv').config();
// Setup your middlewares
// Setup your routes
app.get('/foo', async (req, res, next) => {
//Yout code here
// const doc = await Modal.find();
if(!doc) return next(new sendError('error message here' , status code number here)
res.json({
// your response here
})
});
// the global error handler middleware
app.use(errorsHandler);| Error Type | Error in Production |
