搭建环境
- 安装vite初始化项目
npm init vite-app vue3-pro
- 初始化完项目，通过
cd vue3-pro进行到项目里面，然后再执行npm install安装依赖 - 依赖安装完需要通过
npm run dev启动项目
D:\vscode\git-pro\vue3-pro>npm install
yarn install v1.22.5

集成typescript
- 安装并初始化
typescript,npm 5.x之后的版本中提供了一个npx命令，它可以直接执行node_modules/.bin/目录下的可执行程序，因此我们可以通过它来使用tsc命令
npm install typescript -D
npx tsc --init
2.配置 tsconfig.json

}
}
- 将main.js修改为main.ts,同时将index.html里面的引用也修改为main.ts
<!--将 <script> 修改为 <script lang="ts">-->
- 修改完之后，重启就可以访问项目了。虽然这样配置是可以了，但是打开main.ts会发现ts还没有识别vue文件 imort App from App.vue会报错: Cannot find module './App.vue'
// 项目根目录添加shim.d.ts文件
declare module "*.vue" {
import { Component } from "vue";
const component: Component;
export default component;
}
vue-router
- 可以去
npm官网查找最新版本,安装vue-router
npm install vue-router@4.0.0-beta.7
- 在
src目录下，新建router文件夹，并在文件夹内创建index.ts
// index.ts
import { RouteRecordRaw, createRouter, createWebHistory } from 'vue-router';
const routes: RouteRecordRaw[] = [
{
path: '/',
name: 'Home',
component: import('../views/Home'),
},
{
path: '/about',
name: 'About',
component: () => import('../views/About'),
},
];
const router = createRouter({
history: createWebHistory(),
routes,
});
export default router;
- 将router引入到main.ts中
import { createApp } from 'vue'
import App from './App.vue'
import './index.css'
import router from './router/index'
const app = createApp(App)
// 通过use 将 路由插件安装到 app 中
app.use(router)
app.mount('#app')
集成vuex
- 安装
vuex
npm install vuex@4.0.0-beta.4 -D
- 在
src目录下，新建store文件夹，并在文件夹内创建index.ts
// index.ts
import { state } from './state';
import { createStore } from 'vuex';
export default createStore({
state,
mutations: {},
actions: {},
modules: {},
});
// state.ts
export interface State {
title: string;
}
export const state: State = {
title: 'Vue3.0 与 vite',
};
- 引入到
main.ts中
import { createApp } from 'vue'
import App from './App.vue'
import './index.css'
import router from './router/index'
const app = createApp(App)
// 通过use 将 路由插件安装到 app 中
app.use(router)
app.mount('#app')
