Benchmarking AngularJS performance

Things to optmize

• Use one-time-bind on expressions ( {{::value}} )
• Replace $scope.$apply() with $scope.$digest() whenever possible
• Move filters to controllers

Measuring Watch list

To get the total watchers on the current page, you can run this script on the browser console:

    var dbUrl = 'mongodb://username:[email protected]:port/database-name';
    MongoClient.connect(
      dbUrl,
      function(err, db) {
        if(err) throw err;
        db.collection('ItemModel').find({}).toArray(function(err, docs) {
          console.dir(docs);
          console.dir(docs.length);
          db.close();
        });

@pulkitsinghal here’s a gist of the core of it all:
https://gist.github.com/doublemarked/e4bf329d11c55baf468f

@pulkitsinghal this will log access tokens with all log messages.
Bunyan produces JSON, so you’re essentially going to need to parse
the log to fish out things, but JSON makes it easy to do that.

For simple things (like access tokens) you can also use grep
