By implementing an MVVM framework, it helps to develop applications with less code and more flexibility. Because the Angular JS is fully client-side, it also helps you easily create applications or tablets for mobile devices. For example, YouTube applications on PS3 are created using JS. Hay many features available with AngularJS, here are some striking features are as follows:
2.Validation: AngularJS provides validations forms are a basic requirement for any application that accepts comentarios.
3.Dependency: AngularJS has a built-in dependency injection subsystem that helps developers by making the application easier to develop, understand and test .
4.Plantillas: AngularJS provides a way to create your own HTML templates that can be multiple partial views or even a single page.
Routing: As MVC, angular JS also provides the routing function to switch between viewpoints. story …
AngularJS made its debut in 2009 and was developed as a t to replace the Google Web Toolkit. The previous code name of the JS Angular was “Location-Filtration”. Google’s Misko Hevery and Igor Minar were the founding members of the Angular JS internal development team. Following the success, Angular JS received official support from Google and became an open source framework. Version 1.0 AngularJS was released in 2012 and version 1.5.5 is the current stable version of AngularJS (also known by its codename ‘ice manipulation’).
If you decided to use it for your application then are some of the best practices for Angular JS:
2.Module Your Angle Code: When we start writing applications, we tend to include everything in the main module. This is fine for a small application, but when it comes to managing the code for a more complex tool, which tends to increase in size over time, is a big problem. So always divide your code into appropriate modules. Divide the characteristics of your application into modules and, consequently, create your angular modules. This way you can reuse the modules on another page or view.
3. Avoid DOM manipulations: Most DOM manipulations will be available as a ready-to-use feature of Angular JS, so use these features whenever possible. The reason for this is that the AngularJS has a mechanism that ensures that all its various parts are synchronized. Now, if you manipulate the DOM, AngularJS will trigger the events automatically so that the application state is consistent, which increases the unnecessary overhead in the application. If you still have to do DOM manipulations, always try to make your manipulations within the $ scope function. $ Apply (callback) .
4. Keep business logic in templates: Always keep business logic in templates so you can easily share them between controllers and other services. In this way, we can easily perform unit tests on the models. The template is for application logic that is specific to your application and how you want to interact. Controllers should direct their code only to a method or service that updates their model, and in their model, create help classes to implement this business logic.
5.Validations in AngularJS: AngularJS provides the wonderful feature
6. Use unit tests AngularJS: Unlike other frameworks, the AngularJS provides an excellent framework for testing your models by units. Most of the time, developers do manual tests to see if the code is working or not. Sometimes, to test a small change, the manual test takes longer compared to the development of a unit test. The central team of AngularJS has developed a pair of tools, Protractor and Karma, to perform the unit tests of its AngularJS code. Thank you guys!
7. Invest in naming conventions: The most important thing when developing an application should be to set up consistent naming conventions so your code is easy to read and manageable. Any developer should be able to read your code and keep it in your absence.
8.Define your components: Do not include the components of your model, controller, and factory in a single file. Create three separate files for each one, and write each code accordingly. Something like myapp.module.js, myapp.controller.js, myappfactory.js, and so on.
9.Fields: This is one of the most important features that all developers must deal with. The scope should always be write-only on the controllers and read only on the models. Do not create properties in the scope – use the object.
