AngularJS is an open-source JavaScript framework built and maintained by Google, which facilitates the development of web applications. AngularJS standardizes client-side applications, providing a robust and easy to implement structure in site development.
Why AngularJS?
1. Easy to understand
2. Sponsored by Google
3. Guidelines
4. Well documented
5. Thought for REST
6. Very fast
7. Pattern MVW
8. Dependency Injection
9. Compatible with JQuery (uses a lite version of jquery)
AngularJS is the right choice for any web application, especially if spectacular visual effects are preferred. The result is a fluid and fast site. This is why the Single Page Apps and web applications for mobile devices. AngularJS integrates easily with Bootstrap, enabling responsive applications that can be accessed from both your computer browser and mobile devices. So, it’s easy to create a single web app to see perfectly on any device you’re accessing – PC, tablet, phone, plasma. One of the most significant advantages of AngularJS is the development and maintenance team of the platform, which is made up of dedicated engineers from Google. This gives it benefits such as the performance, robustness, and scalability of the code and makes the platform integrate with web projects. Another good result is the regular updating of the platform with the latest developments in web development. Although AngularJS was taken over by Google in 2010, the platform is still open-source which is an advantage, as it remains free to use and distribute. The structure of applications developed with Angular is intuitive and the framework is flexible enough to ease and speed up the development of projects.
The platform requires an MVVM (Model View View Model) structure, a pattern that takes over the modularity of MVC concepts and makes it extremely easy to integrate HTML templates with Javascript-based data processing (through two-way data binding ). The modules created at the Javascript level in Angular are easy to integrate because the framework comes with the dependency injection capability, which also contributes to the scalability of the code. The page load speed is low because most of the communication with the server is asynchronous and the server calls are low, most of the visual interface being moved to the client (in the browser).
AngularJS enables the creation of responsive applications and improves the user experience on the site thanks to its flexible platform, can easily be integrated with other Enterprise-level Testing (Unit Testing) frameworks as well as with UI design frameworks. As the application is stable and tested, a final optimization of the version to be released in production can be done by simply integrating a publishing automation system.
The ultimate result is a fluid, slim application, developed in a short time, which combines a wide variety of visual effects and exceptional graphics animations. It is easy to maintain and benefits from a high loading speed.
AngularJS is performance, intuitive, attractive and perfectly matches mobile platforms. AngularJs introduces the concept of the directive, this is nothing but a tag that exposes the concept of HTML, a directive is “own tag/attribute” HTML itself. I chose to introduce the directives for the first time because they are the most important in the framework + as the whole angular “spins” around these directives.
All directives provided by the angular start with the keyword “ng” and the examples are a lot (ng-app, ng-controller, ng-model, ng-click, etc.)
Scope
The goal is nothing more than a storage of information (taken from the model) as controllers, directives, etc can use later information.
If you ask why this “$ scope” is so important then I’m going to tell you a few interesting things, it has its own patron and observer, in other words when a property has been changed the whole object will be notified. Hence the beautiful features such as modifying an input lead to changing an entire “real-time” interface.
The goals are hierarchical, with the other purpose a child has all the information from the parent, but in the corner, it is not mandatory that the goals be “hated” they can be isolated.
Modules
Modules can be seen as different/independent parts of an application, a module is the parent application itself that will be defined by ng-app, for example, a user module can be created which can then be injected into another application they need to log in and register, and only some tags like <logging> </ logs>, <registration> </ record>
Data Binding
The term binding date refers to synchronizing the data between the view and the model. In most cases the templating system works in one sense, in other words, the model influences the data view so the propagation of the data is from model to view. In the corner, there is the concept of “two-way data binding” which means any change to the pattern will affect the view, and any changes to the view will be propagated in the model. In other words, data between view and model is automatically synchronized.
Templates
As I think you are expecting the templates (the view) are written in HTML, but not just that, it is mixed with directives (attributes and filters), the display of data in $ scope in view is done by ” {}} “
