Q: Required Node FS module found but can't call functions I am hoping this is something simple that I'm just oblivious to, but I've been looking around for a solution to no avail. 
When I set a variable to "require('fs')," I can see that it is being defined as an object in the scope, but when I try to call something like fs.readFile, I get a function not found exception in the browser. 
var fs = require('fs');

fs.readFile("geo.csv","utf8",function(err,raw){
  //things
});

Is is possible that I'm not assigning the correct object somehow or am I possibly calling the function incorrectly?
Any help would be greatly appreciated!
(Node version is 8.0)
