node.js - Express redirect based off URL -


i'm using express & node.js.

router.get('/:year?/:month?/:day?', function(req, res) {    var date = moment();   if (req.params.year && req.params.month && req.params.day) {     var datestring = req.params.year + " " + req.params.month + " " + req.params.day;     var tempdate = moment(datestring, "dd mm yyyy");     if (tempdate.isvalid()) {       date = tempdate;     }   }     .catch(function (err) {       console.error(err);       res.send("error");     }); });

the above isn't full code route. need pointers. i'm using moment.js(http://momentjs.com/) grab current date, format , pass through url in route.get request.

however, don't want user able go past date. if date has been , user tries navigate want redirect them current date.

.then (function(){   var pastdate = function(req, res) {     if (req.query.[pastdate]) {       res.redirect('/');     } else {}   } })

i don't think the syntax correct. not sure if i'm looking on right lines in how i'd this.

thanks help.

i looked through code , looks inconsisten , don't understand you're trying do, can narrow down this:

router.get('/:year?/:month?/:day?', function (req, res) {   var year = req.params.year;   var month = req.params.month;   var day = req.params.day;      if (year && month && day) {     var requestdate = moment(day + ' ' + month + ' ' + year);     var today = moment();      if (requestdate.isvalid() && !requestdate.isbefore(today)) {       // set , valid, stuff request     } else {       // invalid date or requested date before today       // redirecting /year/month/day of day, e.g /2015/04/31       return res.redirect('/' + today.year() + '/' + today.month() + '/' + today.date());     }   } });

moment has isbefore method handy these kind of tasks.

you should use bit more variables in code it's easier work with! :)
