global-override

Override a global value, even if it has not been set yet.

Install

npm install global-override --save

Use

Use this module to override a global value. For example you could do:

var override = require("global-override");

override("something.deep", function(oldFn){
  return function(){
    return "bar";
  };
});

global.something = {
  deep: function(){
    return "foo";
  }
};

This will override global.something.deep to return the string "bar" instead of "foo".

This is useful if you have some deep object that you want to override that might not be defined right away. global-override will wait for the object to be defined and then hook it so that you can override it yourself.
