How do I implement an error handler using composable-middleware?
This simple example doesn't work for me:
var express = require('express');
var app = express();
var router = express.Router();
var compose = require('composable-middleware');
router.get('testroute', function(req, res, next) {
next(new Error('Test error'));
});
function errorHandlers() {
return compose()
.use(function(err, req, res, next) {
console.log('Error handled!');
});
}
router.use(errorHandlers());
I know async
also has a function called waterfall
to sync the running. This composable-middleware
also make async steps to be synced. So what is the difference between them?
I decide depending on req object which middlewares to push. Synchronously preferably.
Check this for instance:

I'm using connect-sequence
but it doesn't seem to properly call middlewares (here I'm attaching Multer and auth0).
