Essential development tools and techniques for VUE3 beginners

With the rapid development of front-end technology and the continuous expansion of the VUE ecosystem, VUE3 has become one of the popular frameworks for front-end development. This article will introduce beginners to the necessary tools and techniques in VUE3 development to help everyone improve development efficiency and quality.

1. Development Tools

1. Visual Studio Code

Visual Studio Code is a powerful editor that supports the development of various programming languages ​​and frameworks. For VUE development, VS Code also provides a wealth of plug-ins. For example, the Vetur plug-in provides VUE language syntax highlighting, code prompts, formatting, auto-completion and other functions, which is very suitable for beginners in VUE development. Other plug-ins include ESLint, Prettier, Debugger for Chrome, etc., which can improve code quality and debugging efficiency.

2. Vue CLI

Vue CLI is a scaffolding tool for VUE projects that can quickly generate a VUE project and provide rich configuration options and plug-ins. Using Vue CLI can avoid tedious processes such as manual configuration of webpack and babel, and improve development efficiency.

3. Chrome DevTools

Chrome DevTools is a Chrome browser development and debugging tool that can help developers quickly find the problem. During the development process, you can view the data, status, and events of Vue components through Chrome DevTools, and perform real-time debugging and editing.

4. Git and GitHub

Git is a version control tool that can easily manage code versions and changes. GitHub is a Git-based code hosting platform that allows you to upload, share and collaborate on code development. In VUE development, using Git and GitHub can realize code version management, branch management, team collaboration and other functions.

2. Development skills

1. Computed and Watch

In VUE, Computed and Watch are very useful skills that can help developers make it more convenient Handle data and status changes efficiently. Computed can automatically calculate new values ​​based on changes in data, avoiding manual repeated calculations; Watch can monitor changes in data and perform corresponding operations when the data changes. Use these two techniques to simplify your code, improve code reusability and maintainability.

2. Vuex

Vuex is a VUE state management tool used to manage shared state in VUE applications. Use Vuex to centrally manage and distribute status, making it easy to share and update status across components. At the same time, Vuex also provides convenient APIs and tools, such as mapState, mapMutations, mapActions, etc., which can simplify the VUE development process.

3. Component-based development

VUE is a component-based framework that splits a page into multiple components to manage business logic, data status, UI display and other functions respectively. . The reusability and maintainability of components are very good. Using component-based development can improve code reusability and development efficiency. When developing components, you can use Props to pass data, Emit to trigger events, and custom event listeners for communication and interaction between components.

4. One-way data flow

VUE provides the feature of one-way data flow. Data can only be passed from parent components to child components, and child components are not allowed to modify directly. The data of the parent component. Using one-way data flow can avoid data chaos and difficulty in state management, and improve the maintainability of the code.

Summary:

This article introduces the necessary tools and techniques for VUE3 development, including development tools such as Visual Studio Code, Vue CLI, Chrome DevTools, Git and GitHub, as well as Computed and Watch, Development skills such as Vuex, component development and one-way data flow. Beginners can choose corresponding tools and techniques according to their needs to improve development efficiency and code quality.
