与 Vue 2 的差异​

详见： Migration Guide

Vite 配置​

vite.config.ts:

import { resolve } from "path";

function pathResolve(dir: string) {
  return resolve(__dirname, ".", dir);
}

module.exports = {
  alias: {
    "/@/": pathResolve("src"),
  },
  optimizeDeps: {
    include: ["@ant-design/icons-vue"],
  },
};

详见： Vite - Config File

前提准备​

eslint-plugin-vue​

yarn add -D eslint eslint-plugin-vue

.eslintrc.js:

module.exports = {
  extends: [
    // add more generic rulesets here, such as:
    // "eslint:recommended",
    "plugin:vue/vue3-recommended",
    // "plugin:vue/recommended" // Use this if you are using Vue.js 2.x.
  ],
  rules: {
    // override/add rules settings here, such as:
    "vue/no-multiple-template-root": "off",
  },
};

TypeScript​

yarn add -D typescript

详见：

Vue Router​

yarn add vue-router@next

Vuex​

yarn add vuex@next

Ant Design Vue​

yarn add ant-design-vue@next
# import on demand
yarn add -D babel-plugin-import

# https://github.com/vueComponent/ant-design-vue/issues/2798
yarn add @ant-design/colors

.babelrc:

{
  "plugins": [
    ["import", { "libraryName": "ant-design-vue", "libraryDirectory": "es", "style": "css" }] // `style: true` 会加载 less 文件
  ]
}

其他依赖​

yarn add -D sass

开始使用​

使用 TypeScript​

  • main.js 重命名为 main.ts

  • index.html 里把 /src/main.js 替换为 /src/main.ts

    ...
    <body>
      <div id="app"></div>
      <script type="module" src="/src/main.ts"></script>
    </body>
    </html>

使用 Vue Router​

router/index.ts:

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

const routes = [
  {
    path: "/",
    name: "Home",
    component: () => import("/@/views/Home.vue"),
  },
  {
    path: "/setting",
    name: "Setting",
    component: () => import("/@/views/Setting.vue"),
  },
];

export default createRouter({
  history: createWebHistory(),
  routes,
});

使用 Vuex​

store/index.ts:

import { createStore } from "vuex";

export default createStore({
  state() {
    return {
      count: 0,
    };
  },
  mutations: {
    increment(state) {
      state.count++;
    },
  },
  actions: {
    increment(context) {
      context.commit("increment");
    },
  },
});

添加 Views​

views/Home.vue:

<template>
  <h1>This is a home page</h1>
  <HelloWorld msg="Hello Vue 3.0 + Vite" />
</template>

<script lang="ts">
import { defineComponent } from "vue";

import HelloWorld from "/@/components/HelloWorld.vue";

export default defineComponent({
  name: "Home",
  components: {
    HelloWorld,
  },
});
</script>

views/Setting.vue:

<template>
  <div>
    <h1>This is a setting page</h1>
    <p>store count is: {{ count }}</p>
  </div>
</template>

<script lang="ts">
import { defineComponent } from "vue";

export default defineComponent({
  name: "Setting",
  computed: {
    count() {
      return this.$store.state.count;
    },
  },
});
</script>

更改 main.ts​

应用 Vue Router, Vuex, Ant Design :

import { createApp } from "vue";
import router from "/@/router";
import store from "/@/store";

import Antd from "ant-design-vue";
import "ant-design-vue/dist/antd.css";

import App from "/@/App.vue";
import "/@/styles/index.scss";

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

更改 App.vue​

使用 Ant Design 搭建首页布局，其中路由部分如下：

<a-layout-header style="background: #fff; padding: 0">
  <a-row type="flex" justify="end">
    <a-col class="mr-3">
      <a-button
        type="primary"
        shape="circle"
        size="large"
        @click="this.$router.push('/')"
      >
        <template #icon><HomeFilled /></template>
      </a-button>
    </a-col>
    <a-col class="mr-3">
      <a-button
        type="primary"
        shape="circle"
        size="large"
        @click="this.$router.push('/setting')"
      >
        <template #icon><SettingFilled /></template>
      </a-button>
    </a-col>
  </a-row>
</a-layout-header>
<a-layout-content style="margin: 0 16px">
  <div :style="{ padding: '24px', background: '#fff', minHeight: '360px' }">
    <router-view />
  </div>
</a-layout-content>

发布到 GitHub Pages​

编辑 vite.config.ts 添加 base 路径：

module.exports = {
  // otherwise, may assets 404 or visit with index.html
  base: "/start-vue3/",
  assetsDir: "",
};

编辑 router/index.ts 添加 base 路径：

export default createRouter({
  history: createWebHistory("/start-vue3/"),
  routes,
});

编译，再发布：

cd my-site
yarn build

export GIT_HASH=`git rev-parse --short HEAD`

cd dist/
git init
git remote add origin git@github-ik:ikuokuo/start-vue3.git
git checkout --orphan gh-pages
git add .
git commit -m "deploy website - based on $GIT_HASH"
git push origin gh-pages
