I'm using express and I was trying to get connect-flash working, but it
wouldn't work with my redirects. So I've decided to take another approach
and that's just to roll my own middleware for session flashes. Has anyone
had any experience on doing this? I tried to scaffold it but I'm running
into the headers already being sent issue. How can I make this work?
/*
* app.js
*/
app.configure(function() {
app.use(express.cookieParser('keyboard cat'));
app.use(express.session({ key: 'sid', cookie: { maxAge: 60000 }}));
app.use(flashed);
app.use(app.router);
});
function flashed(obj, req, res, next) {
var type = obj[0],
msg = obj[1];
if (obj !== 'undefined') {
req.session.flashType = obj[0];
req.session.flashMsg = obj[1];
res.locals.flashType = req.session.flashType;
res.locals.flashMsg = req.session.flashMsg;
delete req.session.flashType;
delete req.session.flashMsg;
}
next();
}
app.get('/', function(req, res, next) {
flashed(['error', 'my default message'], req, res, next);
res.render('index');
});
