In Vue, modularization is to encapsulate a single function into a module (file). The modules are isolated from each other, but they can expose internal members through specific interfaces, and can also rely on other modules ( Facilitates code reuse, thereby improving development efficiency and facilitating later maintenance). The benefits of modular development: 1. Clear organization and easy maintenance; 2. All data will not be requested back at once, and the user experience is good; 3. Modules are isolated from each other, but internal members can be exposed through specific interfaces, or Depends on other modules.

What is modularity

We say that Vue projects are divided according to modules, so what are modules?

Modularization is equivalent to the navigation bar of our website, then each navigation item can be regarded as

What is modularity in vue# mentioned in the following picture

  • ##Modularization is like a large functional item, and this large functional item can contain multiple components.

  • When used, a single module corresponds to the file directory under the component under our Vue project

  • Each module can have Multiple components, these components constitute a complete module page (single page)

  • But each module must have a

    main file (module parent component), this file must be registered in the routing management (router/index.js). When registering, it must meet the following form:

export default new Router({
  mode: 'history',
  routes: [
		{
      path: '/',
      name: 'Default',
      redirect: '/home',
      component: Home    }]
    })
The remaining components can be injected in the following ways use. When using it, label the name in the name attribute of the component in the parent component (vue will convert the name named in camel case -------- (BookManager——>book-manager) )

    First, you need to import through import in the page you are using
  • Secondly, you need to register in compent. The name attribute of the component will be used when registering. Injection

Summary:

Modularization is to encapsulate a single function into a module (file). They are isolated from each other, but internal members can be exposed through specific interfaces, or they can rely on other modules (to facilitate code reuse, thereby improving development efficiency and facilitating later maintenance).

Why use modularity? The benefits of using modularity

Of course, all functions of the page can be realized without using modular development, but it will increase the pressure on server requests and reduce the user experience. When the page needs When there is too much data, one request contains all the requested data. What if the user does not need it? Is such a request still effective? Of course it has no effect, so this kind of problem can be solved by using the idea of ​​modular development

Briefly talk about the benefits of using modular development

1. Clear organization and easy maintenance

2. All data will not be requested back at once, and the user experience is good

3. Modules are isolated from each other, but internal members can be exposed through specific interfaces, or they can rely on others Module

Comparison between modularization and componentization

1. Componentization is an independent and reusable code organization unit. The component system is one of the core features of Vue. It allows developers to build large applications using small, independent and usually reusable components;

2. Component development can greatly improve application development efficiency, testability, Reusability, etc.;

3. Component usage is classified into: page components, business components, general components;

4. Vue components are based on configuration. The components we usually write are Component configuration rather than components. The framework will generate its constructors later. They are based on VueComponent and extend Vue;

5. Common componentization technologies in Vue include attribute prop, custom events, slots, etc. They are mainly Used for component communication, expansion, etc.;

6. Reasonable division of components can help improve application performance;

7. Components should be highly cohesive and low coupling;

8. Follow the principle of one-way data flow.

The difference between them is

Modularization: it is divided from the perspective of code logic; it facilitates hierarchical development of code and ensures that each functional module has a single function

Componentization: It is divided from the perspective of UI interface. The componentization of the front end facilitates the reuse of UI components [Related recommendations:
