What are Vue dependencies? Why is it important?

Vue.js is a popular JavaScript front-end framework that is widely used in the development of modern web applications. Under normal circumstances, in order to maintain the simplicity and maintainability of Vue.js code, various dependency packages are used in project development. So what are Vue dependencies? This article will explain to you in detail the concept of Vue dependency packages and why we need these dependency packages.

1. What are Vue dependency packages?

Vue.js itself only contains the Vue core library and some simple tool functions, but it does not provide other functions required by a complete web application, such as routing, data requests, state management, etc. In order to meet these needs, Vue.js uses dependency packages to introduce other frameworks and libraries.

2. Why are Vue dependency packages important?

One of the biggest benefits that Vue dependency packages bring to us is that they make our code concise and easy to maintain. In most cases, we don't have to rewrite all this complex functionality, it's already packaged into Vue dependencies for us to use. This helps speed up the development process while keeping the code clean and simple. At the same time, the Vue dependency package also provides us with many optimized options and compatibility, which can improve the user experience while ensuring the security of web applications.

3. What kind of Vue dependency packages do we need?

Although Vue.js already contains a very easy-to-use core library, we usually need other tools and libraries during the development process to implement our business logic and user needs. These frameworks and libraries can greatly improve the efficiency of our code and enhance the functionality of our applications. So what kind of Vue dependency packages do we need?

1. Vuex: State Management Tool

Vuex is a state management tool developed specifically for Vue.js applications, providing centralized storage management of all components of the application. state, making it easier to debug and optimize the state of the entire application. Keeping the state of components in your application synchronized helps centralize data management and reduce code complexity.

2. Vue Router: Route Management Tool

Vue Router is the official route management tool for Vue.js applications. It allows us to set up different components for different URLs in the application. Vue Router allows us to create single page applications (SPA) and selectively update parts of it without reloading the entire page.

3. Axios: Data request tool

Axios is a Promise-based HTTP request client that can be seamlessly integrated with Vue.js. It allows us to easily get data from the server and apply it on the page. Axios supports a variety of configuration options that allow it to work easily with other libraries while masking differences in browsers and Node.js environments.

4. Element UI: UI framework

Element UI is an open source UI framework based on Vue.js. It provides commonly used functions such as buttons, input boxes, tables, etc. User interface elements for web applications. The Element UI framework makes our web application interface development easier and can increase the visual appeal of our applications.

5. Nuxt.js: Server Rendering Framework

Nuxt.js is a server-side rendering framework based on Vue.js, which can make Vue.js applications become Faster and more robust. Nuxt.js is based on the same top-level server-side framework (such as Express or Koa) and provides default out-of-the-box optimization settings and asynchronous data retrieval. This allows us to easily develop server-based web applications and provide users with a smoother user experience.

4. Summary

In the development of modern web applications, Vue dependency packages are an indispensable part. They help us develop applications faster and provide better modularity to our code. One of the benefits of using these dependency packages is that they are very mature and optimized and can be used to implement many common business logic. Therefore, when using Vue.js to build web applications, we should learn how to use and make good use of these dependency packages.
