5 Things To Know Before You Get Started With AngularJSPosted by Itay Herskovits on Sep 23, 2014
Navigating the AngularJS landscape can be a daunting experience. While the library itself is fairly robust, choices early in the adoption process can have drastic long-term effects on your software development process. Below we present five things that you should know about AngularJS. This information won’t solve every problem you’ll have with the library, but it can help you get off on the right foot.
1. AngularJS is Entirely Client-Side
2. AngularJS is Focused on Data
3. AngularJS Provides a Declarative UI
4. AngularJS Data Objects are POJO
5. AngularJS is Built for Testing
Unit and functional testing produce more robust, dependable code. AngularJS was developed with this ideal in mind, and is designed from top to bottom to make testing a relatively painless process. AngularJS uses Dependency Injection (DI) to pass information around, allowing your tests to easily override the function calls and inject appropriate mock data. This is important for writing robust unit tests that isolate the functionality being tested. There are also a number of tools built into AngularJS, such as a mock HTTP provider, that make writing larger functional tests a more dependable endeavor. Finally, there are numerous open-source tools for running test suites in AngularJS, including Karma for running tests and Jasmine for behavior-driven testing
AngularJS is a powerful tool which, when used correctly, can make your presentation layer both more maintainable and more robust. With its focus on data-presentation as a declarative effort, it more closely mimics HTML and its robust interpretations across multiple scenarios. By keeping the above items in mind, you can help direct your development organization in how it uses AngularJS to enhance your application’s data presentation, and prevent long-term pitfalls that can add unnecessary costs and complexity to the development process.
