MEAN: What is the best way to keep a watch on a json file

Some Info:

I am creating a json file from matlab which updates every second with the latest coordinates.For writing file from matlab to json I am using JsonLab.

My problem :

The json file refreshes every second and gets updated .Now i want to show the latest data everytime on the webpage.So this requires loading the json everytime it is refreshed.I am confused about how to do this . I am using MEAN stack (MongoDB, Express, AngularJS, Node). Any help would be appreceiated.

Don't consume it with REST then. Implement http://socket.io/ and consume coordinates with web sockets live data.

You can also maybe consider using Firebase (AngularFire) if you want to have your sockets implementation to be someone else's problem.
