Namespace-It - Apply a namespace to any block of code contained inside a function, or in a javascript file.

Overview of full workflow

Grab the scope variables of a function or a file.

Usage - Step by Step

Require the namespaceit module

const NamespaceIt = require('namespaceit');

Pick any function in your code block. For example...

function someFunction() {
  const number = 1;
  const string = 'string';
  const array = [1,2];
  const object = {
    hey: 'you',
    fn: function() {
      return 1;
    }
  };
  function functionStatement() {
    return 'I\'m a function statement';
  };
  const functionExpression = function() {
    return 'I\'m a function expression';
  };
}

Initialize a new namespaceit object

const namespaceIt = new NamespaceIt('A', someFunction);

Call applyNamespace method

namespaceIt.applyNamespace();

See the magic happen

A.object.fn(); //1
A.array; //[1,2]

Clear the namespace if you want

namespaceIt.clearNamespace();
//A is no longer defined!

Limitations

• Does not currently support arrow function syntax
• Code must be properly linted with semi colons after each line
• Functions with arguments are not yet supported
• Variable declared as a reference to another variable in scope is not yet supported

Improvements

All points under Limitations are being worked on until they are no longer limitations. If this project excites you, feel free to submit a pull request.
