Can someone explain to me about the different between two ways exception error handling in code Express JS below:
const express = require('express');
const app = express();
app.get('/test', (req, res, next) => {
// the first way:
throw new Error('my error message');
// the second way:
next(new Error('my error message'));
});
app.use((err, req, res, next) => {
res.status(err.status || 500).send(err.message || 'Internal Server Error');
});
app.listen(3000, () => console.log('Welcome to ExpressJS'));
It returns the same result handled by error middleware but what is the difference here?
>Solution :
Nothing, based on the source code.
try {
fn(req, res, next);
} catch (err) {
next(err);
}
