-### Compiles and minifies for production
|
|
|
+### 集成eslint
|
|
|
+```bash
|
|
|
+yarn add --dev eslint eslint-plugin-vue
|
|
|
```
|
|
|
-npm run build
|
|
|
+项目根目录创建配置文件`.eslintrc.js`：
|
|
|
+```js
|
|
|
+module.exports = {
|
|
|
+ parser: 'vue-eslint-parser',
|
|
|
+ parserOptions: {
|
|
|
+ parser: '@typescript-eslint/parser', // Specifies the ESLint parser
|
|
|
+ ecmaVersion: 2020, // Allows for the parsing of modern ECMAScript features
|
|
|

|
|
|

|
|
|
+ // tsx: true, // Allows for the parsing of JSX
|
|
|
+ jsx: true,
|
|
|

|
|
|
+ },
|
|
|
+ // settings: {
|
|
|
+ // tsx: {

|
|

+ // }
|
|
|
+ // },
|
|
|
+ extends: [
|
|
|
+ 'plugin:vue/vue3-recommended',
|
|
|
+ 'plugin:@typescript-eslint/recommended', // Uses the recommended rules from the @typescript-eslint/eslint-plugin
|
|
|
+ 'prettier/@typescript-eslint', // Uses eslint-config-prettier to disable ESLint rules from @typescript-eslint/eslint-plugin that would conflict with prettier
|
|
|
+ 'plugin:prettier/recommended', // Enables eslint-plugin-prettier and eslint-config-prettier. This will display prettier errors as ESLint errors. Make sure this is always the last configuration in the extends array.
|
|
|
+ ],
|
|
|
+ rules: {
|
|
|
+ // Place to specify ESLint rules. Can be used to overwrite rules specified from the extended configs
|
|
|
+ // e.g. "@typescript-eslint/explicit-function-return-type": "off",
|
|
|
+ },
|
|
|
+};
|
|
|
```
|
|
|
|
|
|
-### Lints and fixes files
|
|
|
+### 集成pritter
|
|
|
+```bash
|
|
|
+yarn add --dev prettier eslint-config-prettier eslint-plugin-prettier
|
|
|
```
|
|
|
-npm run lint
|
|
|
+项目根目录创建配置文件：`.prettierrc.js`：
|
|
|
+```js
|
|
|
+module.exports = {
|
|
|
+ semi: true,
|
|
|
+ trailingComma: "all",
|
|
|
+ singleQuote: true,
|
|
|
+ printWidth: 100,
|
|
|
+ tabWidth: 2,
|
|
|
+ endOfLine:"auto"
|
|
|
+};
|
|
|
+```
|
|
|
+
|
|
|
+到这一步，一个Vue3+TSX的项目就搭建起来了，以上配置文件的具体内容就不做解释了。
|
|
|
+
|
|
|
+### 修改入口文件
|
|
|
+因为默认项目模板是以`src/main.js`为入口的，我们需要把它修改为`src/main.ts`。
|
|
|
+在`根目录的index.html`中修改入口文件的引用即可：
|
|
|
+```html
|
|
|
+... ...
|
|
|
+<body>
|
|
|
+ ... ...
|
|
|
+ <script type="module" src="/src/main.ts"></script>
|
|
|
+</body>
|
|
|
+</html>
|
|
|
+
|
|
|
```
|
|
|
|
|
|
-### Customize configuration
|
|
|
-See [Configuration Reference](https://cli.vuejs.org/config/).
|
|
|
+### 优化TS类型推断
|
|
|
+在src目录下，创建`shim.d.ts、source.d.ts`
|
|
|
+
|
|
|
+`shim.d.ts`: (这个其实不太需要，因为项目中全是通过tsx开发的)
|
|
|
+```ts
|
|
|
+declare module '*.vue' {
|
|
|
+ import Vue from 'vue';
|
|
|
+ export default Vue;
|
|
|
+}
|
|
|
+```
|
|
|
+`source.d.ts`: (优化编译器提示，声明静态资源文件)
|
|
|
+```ts
|
|
|
+declare const React: string;
|
|
|
+declare module '*.json';
|
|
|
+declare module '*.png';
|
|
|
+declare module '*.jpg';
|
|
|
+```
|
|
|
+
|
|
|
+### 集成vue-router
|
|
|
+```bash
|
|
|
+yarn add --dev vue-router@4.0.4
|
|
|
+```
|
|
|
+这里可以去`npm官网`查找最新版本
|
|
|
+在src目录下，`新建router文件夹`，并在文件夹内`创建index.ts`
|
|
|
+`index.ts`:
|
|
|
+```js
|
|
|
+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;
|
|
|
+
|
|
|
+```
|
|
|
+这里创建router的方式与之前不同，在vue3中，结合TS的类型推断，开发效率会高很多。
|
|
|
+
|
|
|
+### 集成vuex
|
|
|
+
|
|
|
+```bash
|
|
|
+yarn add --dev vuex@4.0.0
|
|
|
+```
|
|
|
+在src目录下，新建store文件夹，并在文件夹内创建`index.ts`
|
|
|
+
|
|
|
+`index.ts`:
|
|
|
+```js
|
|
|
+import { state } from './state';
|
|
|
+import { createStore } from 'vuex';
|
|
|
+
|
|
|
+export default createStore({
|
|
|
+ state,
|
|
|
+ mutations: {},
|
|
|
+ actions: {},
|
|
|
+ modules: {},
|
|
|
+});
|
|
|
+```
|
|
|
+`state.js`:
|
|
|
+```js
|
|
|
+export interface State {
|
|
|
+ title: string;
|
|
|
+}
|
|
|
+
|
|
|
+export const state: State = {
|
|
|
+ title: 'Vue(v3) 与 tsx 的结合~',
|
|
|
+};
|
|
|
+```
|
|
|
+### main.ts
|
|
|
+最终main.ts中引入store、router：
|
|
|
+```js
|
|
|
+import { createApp } from 'vue';
|
|
|
+import App from './App';
|
|
|
+import router from './router';
|
|
|
+import store from './store';
|
|
|
+
|
|
|
+createApp(App).use(router).use(store).mount('#app');
|
|
|
+```
|
|
|
+### TSX
|
|
|
+最终我们的组件代码，都会是这样的：`App.tsx`:
|
|
|
+```js
|
|
|
+import { defineComponent } from 'vue';
|
|
|
+import {RouterLink, RouterView} from 'vue-router';
|
|
|
+import './style/main.scss'
|
|
|
+
|
|
|
+export default defineComponent({
|
|
|
+ name: 'App',
|
|
|
+ setup() {
|
|
|
+ return () => (
|
|
|
+ <>
|
|
|
+ <div id="nav">
|
|
|
+ <RouterLink to="/">Home</RouterLink> |
|
|
|
+ <RouterLink to="/about">About</RouterLink>
|
|
|
+ </div>
|
|
|
+ <RouterView/>
|
|
|
+ </>
|
|
|
+ );
|
|
|
+ }
|
|
|
+});
|
|
|
+```
|
|
|
+自我感觉TSX比模板好多了，并且html、组件标签的属性都带有类型推断。
|

|
+## 结尾
|
|
|
+vue3正式版的发布，势必导致vue2的周边框架的集体更新，例如UI框架、基于Vue2的指令库等，作为这么久的白嫖党，也要为vue3社区的建设出一份力了。
|
|
|
+
|
|
|
+
|
|
|
+Vue3与TS的结合是大趋势，如果不适应TS，那还是建议使用Vue2吧。23333~
