JavaScript for Line of Business Applications

AngularJS two way data-binding is at the same time a great strength and its Achilles heel. Dealing with complex and/or large collections of items can significantly slow down rendering. We started looking for a solution to this problem and stumbled upon things like Thierry Nicola's post about his use of React to improve AngularJS rendering time.

When building AngularJS apps, it can be challenging to access data and services hidden deep in our application through the Javascript console in Chrome, Firefox, and IE. Here are some simple tricks we can use to inspect and control a running Angular app through the browser Javascript console, making it easy to test, modify, and even program our Angular app in real-time:

1: Access Scopes
2: Inspect the Scope Tree
3: Grab any Services
4: Access controller for directive
5: Chrome Console Features
6: Conclusion

This course will teach you the AngularJS fundamentals and the internal. The course will cover directives, binding, filters, ngRepeat, testing, isolate scopes and much much more, with real-world examples. ng-course, the best course in israel.

In order to create a single page application with good perceived latency and good user experience, the SPA engine must handle the browser native behavior in many aspects, for instance:

SEO & Bookmarkability: Sharing or bookmarking a link should always display the same content. Sending a link to a friend should get them where we were. More than that, search engines are able to index that same content.

Hybrid rendering: Ajax + server-side rendering allows disable pushState at any time, allowing progressive enhancement. The way you render the server side doesn't matter, it can be simple HTML fragments or even template views.

State retention: Scrolling, reloading or navigating through the history of the page should get back to where it was.

UI feedback: When some content is requested, it indicates to the user that something is happening.

Pending navigations: Block UI rendering until data is loaded, then displays the content at once. It's important to give some UX feedback during loading.

Timeout detection: Timeout if the request takes too long to load or when navigate to a different link while another request is pending.

History navigation: By using History API you can manipulate the browser history, so you can use browser's back & forward buttons.

Cacheable screens: Once you load a certain surface this content is cached in memory and is retrieved later on without any additional request. This can speed up a lot your application.

Page resources management: Evaluate scripts and stylesheets from dynamic loaded resources. 

Let’s go back to our Component which is the main React’s object. You can create complicated Web interfaces by combining Components. Each one of them implements render() where the temporary DOM is created and this rendering can be hierarchic. This way the Components tree is created. Each block contains of its current state and is re-rendered after any change. Changes in parent’s component are also passed to children.

Angular, Backbone and Ember all have the concept of views, events, data models and routing. We will compare their differences and outline ideal use cases.

In the past we’ve gone over how to use the great UI-Router for creating AngularJS applications. It provides great flexibility and power when defining states and nested states in your application. Today we’ll be going over three features that UI-Router provides that you might find useful when building your own applications.

Before we take dive in, if you need a quick overview of UI-Router, take a look at our starter guide and an example of UI-Router in action in a multi-step form.
