Essential development skills and best practices for VUE3 beginners

Vue3, as the latest Vue version, has many new features and improvements. For beginners, after initially mastering some development skills and best practices, they can better apply Vue3 for development. This article will introduce the necessary development skills and best practices for VUE3 beginners so that they can better start applying Vue3 for development.

1. Vue3 development skills

1. Use Vue official tool library

The Vue community has a wealth of plug-ins and tools, but not all plug-ins and tools can be officially recognized. The Vue official tool library provides some officially recommended plug-ins and libraries to help developers develop better. For example, Vue Router and Vuex, etc.

2. Modular organization code

In Vue3, the component uses a new API, so the code structure of the component should also be improved accordingly. Modular organization of code can better improve the maintainability and readability of the code. It is recommended to put the HTML, CSS and JavaScript code of each component in the same file.

3. Using the Composition API

The Composition API is one of the new features provided by Vue3, which provides a better way to organize and reuse code. Use the Composition API to better divide code blocks and improve code maintainability. Therefore, in Vue3, it is recommended to use the Composition API to write components.

4. Using TypeScript

TypeScript is a type-safe superset of JavaScript that can help developers prevent many code errors. Vue3 officials strongly recommend developers to use TypeScript to write Vue projects. TypeScript can be seamlessly integrated with Vue3 and improve code readability and maintainability.

5. Using asynchronous components

The async component feature has been added to Vue3. Using asynchronous components can improve the performance of your application because components are only loaded when needed. You can use the Vue.lazy() method and the Suspense component to implement asynchronous component loading.

6. Using Vue Devtools

Vue Devtools is a Vue development plug-in that can view and debug Vue applications in the browser. Vue Devtools can provide real-time data flow and component tree view to facilitate developers to debug and view the status of Vue applications.

2. Vue3 best practices

1. Using templates

In Vue3, templates use a new compiler and syntax. Use templates to better organize and manage your app's views and improve your app's readability and maintainability. It is recommended to use Vue3 templates to write application views, and use Vue instructions and template syntax to implement the data binding and logic of the views.

2. Keep the component simple

When writing Vue components, it is recommended to keep the component simple and split the component into smaller components as much as possible. This increases the reusability of components and allows for better organization and management of code. At the same time, keeping components simple can also reduce code duplication and coupling of components.

3. Using Vue3’s responsive system

Vue3’s responsive system provides more efficient data response, which can effectively reduce application performance overhead. Using Vue3's reactive system can better maintain and manage the state of the application, and reduce repeated code about state.

4. Code separation

Code separation is a method of optimizing application performance by reducing unnecessary code loading and rendering. In Vue3, you can use the Vue.load() method to load components asynchronously to achieve code separation.

5. Organizing code based on routing

Vue Router is Vue's routing management library, which can help developers manage application routing. Vue Router also provides some hooks and life cycles that can be used to organize and manage application code.

6. Writing unit tests

Writing unit tests can improve the maintainability and reliability of the application. Vue3 provides some APIs and tools for writing unit tests. It is recommended that developers make full use of these APIs and tools to write test cases.

Summary

In Vue3, you can develop better by using Vue official tool library, modular organization of code, using Composition API, using TypeScript, asynchronous components, and using Vue Devtools. . At the same time, best practices such as keeping simple components, using Vue3's responsive system, code separation, organizing code based on routing, and writing unit tests can improve the maintainability and reliability of the application. I hope the above suggestions can help beginners better apply Vue3 for development.
