How to create a Vue3 project using Vue CLI?

Vue.js is a popular front-end framework, and by using Vue, you can easily build interactive user interfaces. Vue3 is the latest version of Vue.js, bringing many exciting new features and improvements. This article will detail how to use Vue CLI to create a Vue3 project, and provide some useful tips to help you get started quickly.

Part 1: Installing the Vue CLI

Before starting to create a Vue3 project, you need to install the Vue CLI tool. Vue CLI provides a command line interface to help you create, manage and build Vue.js projects more easily. Here are the steps to install Vue CLI:

Open Terminal (for macOS and Linux users) or Command Prompt (for Windows users).
Run the following command to install Vue CLI globally:
```
npm install -g @vue/cli
```
This will install the latest version of Vue CLI globally on your computer.
After the installation is complete, you can verify the installation results by running the following command:
```
vue --version
```
If the version information of Vue CLI is displayed, the installation is successful.

Part 2: Create a Vue3 project

Once you've installed the Vue CLI, it's time to create a new Vue3 project. Follow the steps below:

Open a terminal (or command prompt) and change into the directory where you want to create the project.
Create a new Vue3 project by running the following command:
```
vue create my-vue-project
```
Replace my-vue-projectwith your custom project name.
This will start an interactive project creation process. You can choose the default options, or manually choose which feature plugins to add. Press the Enter key to confirm the selection.
After the creation is complete, enter the project directory:
```
cd my-vue-project
```
You have now successfully created a Vue3 project.

Part III: Developing and Building the Project

Change into your Vue3 project directory and run the following command in a terminal to start the development server:
```
npm run serve
```
This will start a local development server, listening for changes to your code.
Open it in your browser http://localhost:8080(port 8080 by default) to preview your Vue3 project. If everything is fine, you will see a welcome page.
Next, open the project directory in your code editor and start editing src/App.vuethe file. This is your root component where things like page layout and logic can be added and modified.
As you develop, Vue CLI automatically reloads pages, allowing you to see the effects of your changes in real time.
When you're ready to deploy your project to production, you can build it with the following command:
```
npm run build
```
This will generate you an optimized, production-ready build of your project. Build results will be stored in distthe directory.
You can upload the generated file to your server, or deploy it to a static file hosting service (such as Netlify, Vercel, etc.) for live deployment.

Part IV: Common Configurations and Tips

During the development of Vue3 projects, the following are some common configurations and techniques that can help you better use Vue CLI and Vue3:

Custom configuration: You can customize vue.config.jsVue CLI's default configuration by editing the file in the project root directory. For example, you can configure a proxy server, modify the output directory, etc.
Use single-file components: Vue3 introduces the Composition API, which supports using single-file components to write more flexible and maintainable code. Components can be defined by creating .vuea file and putting HTML, CSS and JavaScript code in the same file.
Routing management: Vue Router is the official routing manager provided by Vue.js. You can use Vue Router to create dynamic single-page applications. You can add Vue Router to your Vue3 project by running:
```
vue add router
```
State management: Vue3 recommends using Vuex as the state management tool for the application. You can use Vuex to share and manage data between different components. You can add Vuex to your Vue3 project by running:
```
vue add vuex
```
Use plugins and libraries: There are many excellent plugins and libraries to choose from in the Vue3 ecosystem that can speed up the development process. You can vue addadd plugins, libraries, and other features such as Axios, Element UI, etc. by running the command.

These are just some common configurations and tricks that will help you use Vue CLI and Vue3 better. If you want to know more advanced usage, please refer to the official documentation of Vue3 or search related resources.
