Vue3 TS Vite development skills: How to quickly build a Vue3 TS Vite development environment

In modern web development, Vue.js is one of the most popular front-end frameworks one. Vue3, as the latest version of Vue.js, brings more features and performance improvements. TypeScript, as a statically typed superset of JavaScript, provides more powerful development tools and type checking capabilities. Vite is a very fast construction tool that focuses on the development environment and can help us quickly build the development environment for the Vue3 TS project. This article will introduce how to use Vite to build a Vue3 TS development environment, and provide some development tips and code examples.

Preparation

Before you begin, make sure you have the latest versions of Node.js and npm installed.

Initialize the project using Vite

First, we need to install Vite's command line tool globally. Open the terminal and run the following command:

npm install -g create-vite

After the installation is complete, we use the create-vite command to create a new project. Execute the following command in the terminal:

create-vite my-vue3-project --template vue-ts

The above command will create a Vue3 TS project named my-vue3-project and automatically initialize some basic configuration and files.

Enter the project directory:

cd my-vue3-project

Install project dependencies:

npm install

Start the project:

npm run dev

Open http://localhost:3000 in the browser , you will see a basic Vue3 TS application running.

Add Vuex and Vue Router

In many actual projects, we often use Vuex as a state management library and Vue Router for routing management. Below we will introduce how to add them to our Vue3 TS project.

First, install Vuex and Vue Router:

npm install vuex@next vue-router@next

Create a store directory in the src directory and create an index.ts file in it to initialize Vuex. The sample code is as follows:

import { createStore } from 'vuex'

// 创建一个基本的store
const store = createStore({
  state: {
    count: 0
  },
  mutations: {
    increment(state) {
      state.count++
    },
    decrement(state) {
      state.count--
    }
  }
})

export default store

Create a router directory in the src directory and create an index.ts file in it to initialize Vue Router. The sample code is as follows:

import { createRouter, createWebHistory } from 'vue-router'
import Home from '../views/Home.vue'

const routes = [
  {
    path: '/',
    name: 'Home',
    component: Home
  }
]

const router = createRouter({
  history: createWebHistory(),
  routes
})

export default router

Now, we need to introduce and use store and router in the main.ts file. The sample code is as follows:

import { createApp } from 'vue'
import App from './App.vue'
import store from './store'
import router from './router'

const app = createApp(App)

app.use(store)
app.use(router)

app.mount('#app')

TypeScript configuration

In order for TypeScript to work properly, we need to add a tsconfig.json file in the project root directory and perform some basic configurations.

Create the tsconfig.json file in the project root directory and add the following content:

{
  "compilerOptions": {
    "target": "esnext",
    "module": "esnext",
    "strict": true,
    "jsx": "preserve",
    "importHelpers": true,
    "moduleResolution": "node",
    "esModuleInterop": true,
    "experimentalDecorators": true,
    "allowSyntheticDefaultImports": true,
    "sourceMap": true,
    "typeRoots": ["./node_modules/@types", "./src/types"],
    "types": ["vite/client"]
  }
}

In this way, we have completed the initialization and basic configuration of the Vue3 TS Vite project. Now, we can develop according to actual needs and take advantage of the features and tools provided by Vue3 and TypeScript to improve development efficiency.

Summary

This article introduces how to quickly build a Vue3 TS Vite development environment, and provides some sample code and development tips. By using Vite, we can quickly create a modern Vue3 TS project environment. Using TypeScript can provide more powerful development tools and type checking capabilities, helping us write more reliable and maintainable code. I hope these tips can help you improve development efficiency and quality in your Vue3 TS project.
