2. What We’re Going to Do
• Get our hands dirty with KnockoutJS
• Some basic knowledge of Javascript, Apex and Visualforce
would be beneficial
• We’re going to build a simple, fast, contact viewer
3. KnockoutJS?
• KnockoutJS is a Javascript framework for building quick,
single-page applications
• Requires less boilerplate that a lot of frameworks, and is
conceptually simpler than many
• Turns out it’s very easy to use with Javascript remoting!
4. KnockoutJS Architecture
• Knockout uses a Model – View – View Model (MVVM)
pattern
• The Model is our Salesforce schema and data
• The View displays data from, and triggers actions on the
view model
• The View Model is pure code that interacts with the
model, and provides data and actions for the View
5. View Model and Bindings
• The View Model has properties called observables:
self.name = ko.observable(‘Bob’);
• The View can bind to these:
<span data-bind=“text: name”/>
• When the observable value changes, the view changes!
