Format date and Subtract days using Moment.js

Try this:

var duration = moment.duration({'days' : 1});
moment().subtract(duration).format('DD-MM-YYYY');

This will give you 14-04-2015 - today is 15-04-2015

Alternatively if your momentjs version is less than 2.8.0, you can use:

startdate = moment().subtract('days', 1).format('DD-MM-YYYY');

Instead of this:

startdate = moment().subtract(1, 'days').format('DD-MM-YYYY');

var date = new Date();

var targetDate = moment(date).subtract(1, 'day').toDate(); // date object

Now, you can format how you wanna see this date or you can compare this date with another etc.

toDate() function is the point.

startdate = moment().subtract(1, 'days').format('DD-MM-YYYY');

You have multiple oddities happening. The first has been edited in your post, but it had to do with the order that the methods were being called.

.format returns a string. String does not have a subtract method.

The second issue is that you are subtracting the day, but not actually saving that as a variable.

Your code, then, should look like:

var startdate = moment();
startdate = startdate.subtract(1, "days");
startdate = startdate.format("DD-MM-YYYY");

However, you can chain this together; this would look like:

var startdate = moment().subtract(1, "days").format("DD-MM-YYYY");

The difference is that we're setting startdate to the changes that you're doing on startdate, because moment is destructive.
