slim.js

slim.js makes interactivity creation a joy. Design any view for you application and the fast implementation of slim.js will take care of the reactivity. Any property change or event triggered in your app will efficiently update your DOM only when it needs to. It is expressive as you would like it to be: anything typed inside handlebars will execute as-is, causing efficient re-render only of the affected nodes. The slim.js core is tiny (less than 3kB gzipped) - It scans the HTML and looks for handlebars syntax. Anything inside is your code. It just executes it as functions in your component's scope, only when your properties change, and only for the relevant ones. slim.js is extensible. You can add your own custom directives to the registry with a simple API, or add global plugins that execute's your code on every step of a component's lifecycle.
