How to display the amount of documents in a collection in ejs? With mongodb

Question

I am trying to display the amount of available documents that are in a collection. The collection name is "merchant1".

This is the backend:

 router.get('/merchanttrading', ensureAuthenticated, (req, res) => { const user = req.user; merchant1.find({}, function (error, data) { res.render("merchanttrading", {data, user: req.user}); }) })

And this is what I am trying in the front end:

 <% for (var i = 0; i < data.length; i++) { %> <h2 id="test"><%= data[i].length%></h2> <% } %> <script> <% for (var i = 0; i < data.length; i++) { %> var documentamount = <%= data[i]%> <% } %> </script>

But this will just up ending beign blank. Rendering the entire document just works fine but what I want is to show the amount of current documents in the collection as a number and not the document itself.

Any help would be appreciated.

I have found a solution after more digging I came across this: https://www.mongodb.com/docs/manual/reference/method/db.collection.count/

Then I used that like this:

 router.get('/merchanttrading', ensureAuthenticated, (req, res) => { const user = req.user; merchant1.count({}, function (error, data) { res.render("merchanttrading", {data, user: req.user}); }) })

The solution seemed to easier then I thought and I was just over thinking it.
