How to build the architecture of vue

With the continuous advancement of modern front-end technology, Vue.js has become one of the preferred frameworks for many front-end developers. As a lightweight, efficient, and componentizable JavaScript framework, Vue.js can quickly build an interactive UI interface, and the page can be built by simply splicing components.

When developing a Vue.js application, it is very important to build a good architecture. A good architecture can make the application have good scalability, maintainability and reusability. In this article, we will introduce how to build an application architecture based on Vue.js.

Step One: Divide the Structure

Before we start building the architecture, we need to split a complex Vue.js application into multiple modules. These modules can be functional modules or business modules. Generally speaking, a Vue.js application should be divided into three layers of architecture: view layer, data layer and service layer.

• View layer: responsible for displaying data and responding to user operations, and is composed of Vue components.
• Data layer: Responsible for managing the status, data and behavior of the application. You can use Vuex to manage the status of the application.
• Service layer: Responsible for managing external services and interfaces required by applications, such as RESTful API, GraphQL, etc.

Step 2: Choose a build tool

When building an application architecture, it is very important to choose the appropriate build tool. Commonly used build tools in Vue.js include Webpack, Gulp, Grunt, etc. Among them, Webpack is currently one of the most popular building tools and can be used for file packaging, code conversion, module loading and other tasks.

When building with Webpack, we need to configure some basic parameters and plug-ins, such as vue-loader, babel-loader, eslint-loader, etc. At the same time, we also need to define the entry and exit, as well as the address and loading order of the files in the webpack configuration file.

Step 3: Create Vue components

When creating an application, we need to create some regular Vue components. These components can be basic components, such as Button, Icon, Input, or composite components, such as form components, asynchronous request components, etc.

When creating components, we need to divide them by function, purpose and reusability. At the same time, we also need to implement communication and data transfer between components through props and events.

Step 4: Use Vuex for state management

In Vue.js applications, state management is a very important issue. On the premise of a single state tree, Vuex can help us manage the state of the entire application efficiently. Vuex is a state management tool developed specifically for Vue.js, with powerful features and an easy-to-use API.

When using Vuex for state management, we need to define store, state, mutation, getters and actions. The store is responsible for managing the data flow of the entire application and providing different methods and properties for components to use. state stores the state of the entire application, mutations are used to change the application state, getters are used to obtain certain objects or values ​​from the state, and actions are used to handle asynchronous operations.

Step 5: Use Axios to handle network requests

In modern web applications, handling network requests is a very important part. In Vue.js, we can use Axios for network request processing. Axios is a Promise-based HTTP library that can easily handle asynchronous requests and file uploads.

When using Axios to send a network request, we need to set the request address, request parameters, request headers and other information. At the same time, we also need to add some interceptors before and after the request to do some unified processing of the request and response.

Step 6: Use ESLint for code inspection

During the development process, we need to always maintain the standardization and readability of the code. To avoid coding errors and invalid code, we can use ESLint for code inspection. ESLint is a general JavaScript code inspection tool that can help us standardize and optimize code quality.

When using ESLint for code inspection, we need to define the code rules and add the eslint-plugin-vue plug-in to the project. At the same time, we can also constrain code standardization through Eslint-Config-Airbnb rules.

Step 7: Code splitting and on-demand loading

As the Vue.js application continues to expand, the code size will become larger and larger. To improve the performance and loading speed of your application, we can avoid loading all the code at once through code splitting and on-demand loading.

Using the asynchronous components provided by Vue.js and the Code Splitting function of Webpack, we can achieve code splitting and on-demand loading. Among them, asynchronous components use the import() method to import components, thereby dividing the components into independent code blocks. At the same time, using Webpack's Code Splitting feature, we can package components into independent files and load them when needed.

Summarize

The above are the steps to build an overall architecture based on Vue.js application. In actual project development, we also need to make appropriate adjustments and changes to the architecture according to specific circumstances. But no matter what, building a good application architecture is always one of the important steps to improve development efficiency, maintain code quality, and meet project needs.
