Module details in AngularJS _ AngularJS

This article mainly introduces the module details in AngularJS. This article provides a module example. If you need a friend, you can refer to some angular knowledge points before talking about the angularjs module:

AngularJS is a pure client-side technology that is fully written in Javascript. It uses conventional web development technologies (HTML, CSS, and Javascript) to make web application development faster and easier.

An important method for AngularJS to simplify application development is to package some common low-level development operations for developers. AngularJS automatically handles these low-level operations. They include:

1. DOM operations
2. Set event listening
3. for input verification, AngularJS will handle most of these operations, so developers can focus more on application business logic and write less repetitive, error-prone, and low-level code.

While AngularJS simplifies development, it also brings some exquisite technologies to the client, including:

1. Separation of data, business logic, and views
2. Automatic Binding of data and views
3. General Services
4. Dependency injection (mainly used for aggregation services)
5. extensible HTML Compiler (fully written by JavaScript)
6. Easy to test
7. The client's requirements for these technologies have existed for a long time.

At the same time, you can also use AngularJS to develop single-page or multi-page applications, but it is mainly used to develop single-page applications. AngularJS supports historical browser operations, forward and backward buttons, and favorite operations in a single-page application.

Next, we will explain in detail the angularJS module.

Most applications have a primary method for instantiating, organizing, and starting applications. AngularJS applications do not use the main method, but use modules to declare how the application should be started. This method has the following advantages:

1. the startup process is declarative, so it is easier to understand.
2. In unit tests, you do not need to load all modules. Therefore, this method helps write unit tests.
3. Additional modules can be added to tests under specific circumstances. These modules can be configured to help with end-to-end testing.
4. Third-Party code can be packaged into reusable modules.
5. The module can be loaded in any successive or parallel Order (because the execution of the module itself is delayed ).
