ns

JavaScript namespace tool

Features

ns provides two simple but useful features:

1. Easy namespacing with automatic nested initialisation:

// Assigns the function to window.MyApp.Security.authenticate.
// NOTE: window.MyApp and may not be initialised yet.
ns("MyApp.Security.authenticate", function(username, password) { /* .. */ } );

// Assigns the object to window.MyApp.Security.credentials.
// NOTE: Existing assignments within the namespace are kept.
ns("MyApp.Security.credentials", {username: "g105b", password: "s3cr3t123"});

// Shorthand nested namespaces for less typing:
var sec = MyApp.Security;
// Pass the credentials to the authentication function:
sec.authenticate(sec.credentials.username, sec.credentials.password);

2. Simple document-ready callback for modern browsers:

// Show the alert when the DOMContentReady event fires:
go(function() { alert("DOM is loaded!"); });

// Assign your namespaced function to load on DOMContentReady:
go(MyApp.UI.init);

// Assign multiple callbacks one after another, like this:
go(MyApp.UI.enhance);
go(MyApp.Forms.validate);
go(function() { console.log("DOM loaded!"); });

// Or assign them as an array:
go([
    MyApp.UI.enhance,
    MyApp.Forms.validate,
    function() {
        console.log("DOM loaded!");
    },
]);

// If you want to trigger the callback manually:
var callback = go(myFunc);
callback();

Testing

Tests are written using tape and can be run using Node like this:

npm install tape
node test/test-case.js
