Declarative AJAX - Minimizing Complexity In Modern Web Applications

About this Presentation

Declarative programming describes what a program should achieve in terms of a problem domain, rather than describing how to achieve it using a sequence of primitive operations. It has long been considered a powerful tool for minimizing complexity of software systems. In this talk we will discuss how to apply the declarative programming paradigm to modern AJAX-based web applications using intercooler.js.

We will begin with a brief overview of intercooler.js, a library that enables a declarative approach to AJAX requests. We will discuss:

• The core HTML attributes that drive an intercooler-based web application
• Declarative mechanisms for triggering AJAX requests
• Intercooler request and response formats, including custom HTTP Headers
• CSS Transitions

Once we have covered these basics, we will examine a few typical web application UX needs and how they can be addressed using the declarative style:

• Inline editing
• Lazy loading elements on a page
• Infinite scrolling
• Bulk table operations with visual easements
• Implementing a Pause/Play UI to tail a server side resource

After this talk, the attendee should have a good grasp of how to build a modern web application using declarative programming techniques with intercooler.js
