async-catcher
async-catcher is an error catching wrapper for ES7 async/await functions in express.
Usage
var catcher = require('async-catcher')
app.get('/my/url', catcher(async function(req, res) {
throw Error('Unhandled error');
}));
In this scenario, the default handler will call Express's next()
function and pass in the unhandled error.
You may also supply a handler:
var catcher = require('async-catcher')
app.get('/my/url', catcher(async function(req, res) {
throw Error('Unhandled error');
}, function(err, req, res){
res.status(400).send('An error occurred');
}));
NOTE
This module does not inherently add async support, but plays well with the transpiled implementations from Babel and Traceur.
