Instagram followers js

readMe.txt

You’re going to need to register an app with Instagram https://instagram.com/developer/, install node, get auth tokens and run this script. For my own account with less than 100 followers it was fine, but for my friends account with 200,000 it errors out in ways I haven’t been able to trap. And then we lost interest in it. 

http://iconosquare.com/instagram-statistics probably does a better job...

followers.js

/*
1:
Install node: http://nodejs.org/download/

2:
Get an access token from Instagram for the user: https://instagram.com/developer/authentication/

3:
Open terminal, cd into the directory where followers.js is.
eg:
cd Desktop/

4:
Run the followers js with node: node followers.js <<access token>>
eg:
node followers.js <<access token>>

5:
Wait. Eventually you'll have followers numbers. Or lots of errors :-(
