从零搭建vue3+vite+ts项目

1. 初始化项目

npm init vite@latest

Need to install the following packages:
  create-vite@latest
Ok to proceed? (y) y
√ Project name: ... todos-list
√ Select a framework: » vue
√ Select a variant: » vue-ts

Scaffolding project in D:\Learning\todos-list...

Done. Now run:

  cd todos-list
  npm install
  npm run dev

2.. 配置路由

npm i vue-router

src/route/index.ts(没有的直接创建对应文件夹和文件即可)

import { createRouter, createWebHistory, RouteRecordRaw } from "vue-router";

// 2. 配置路由
const routes: Array = [
  {
    path: "/home", // 路由路径
    component: () => import("@/pages/home.vue"), // 对应组件
  },
];
// 1.返回一个 router 实列，为函数，里面有配置项（对象） history
const router = createRouter({
  history: createWebHistory(),
  routes,
});

// 3导出路由   然后去 main.ts 注册 router.ts
export default router;

src/main.ts

import { createApp } from "vue";

import App from "./App.vue";
// 路由
import router from "@/router";

const app = createApp(App);
app.use(router).mount("#app");

ps:  引入的地方用@报错的同学 是因为别名没有配置(下图...为其他配置项)

{
  "compilerOptions": {
    ...
    "paths": {
      "@/*": ["src/*"],
    },
    ...
  }
}

3. 配置store

2.0 版本使用的市Vuex，3.0官网推荐使用pinia

npm i pinia

src/store/index.ts(同上面路由)

import { createPinia, defineStore } from "pinia";
const store = createPinia();

export const useStore = defineStore("storeId", {
  state: () => {
    return {},
  },
  actions: {},
  getters: {},
});

export { store };

可在state return出来的对象里自定义属性，Vuex中的mutation方法 在pinia中不再使用

src/main.ts

import { createApp } from "vue";

import App from "./App.vue";
// 路由
import router from "@/router";
// store
import { store } from "@/store";

const app = createApp(App);
app.use(router).use(store).mount("#app");

在对应页面或组件中使用store
