express-error-handle

A graceful error handle for Express applications. This also patches a DOS exploit where users can manually trigger bad request errors that shut down your app.

Installation

npm i --save express-error-handle

Express express-error-handle

//If the import statement doesn't work, use require module
const {errorLog,errorHandlerNotify} = require("express-error-handle") //use require
const express = require('express');

const app = express()
const port = process.env.PORT || 5000;

app.get('/a-typical-route',async function(req, res, next) {
try{

//your code here

}
catch(error){
next(error)
}

});


app.listen(port, () => {
console.log(`Example app listening on port ${port}`)
})

//handling error using at the end of last routes
//app.use(errorLog);  //optional
app.use(errorHandlerNotify); //required
