vite + ts 项目搭建
创建项目
// 1. 全局安装vite
npm i vite -g
// 2. 创建项目
npm init vite@latest
// 3. 输入项目名称，选择模板
// 4. 按提示运行npm install ， npm run dev

看上面的截图，这里面没有vue+ts 所以后面要手动添加ts，如果有vue+ts直接选择就好。
vite.config.js
import { defineConfig } from 'vite'
// import path from 'path'
import vue from '@vitejs/plugin-vue'
import vueJsx from '@vitejs/plugin-vue-jsx'
import { resolve } from 'path'
// https://vitejs.dev/config/
export default defineConfig({
server: {
host: '0.0.0.0', //use `--host` to expose
port: 8099,
open: true
},
resolve: {
alias: {
"@": resolve(__dirname, 'src')
},
},
plugins: [vue(), vueJsx()]
})
集成ts
-
安装ts
npm i typescript -S -
创建tsconfig.json 文件
npx tsc --init -
将main.js改成main.ts，index.html引入也改成mian.ts
-
在项目根目录创建shim.d.ts文件，文件内 写入以下文件，用于ts识别.vue文件
declare module "*.vue" {
import { Component } from "vue";
const component: Compoent;
export default component;
}
tsconfig.json
{
"compilerOptions": {
"target": "es2016",
"jsx": "preserve",
"module": "esnext",
"moduleResolution": "node",
"baseUrl": "./",
"paths": {
"@/*": [
"src/*"
]
},
"strict": true,
"skipLibCheck": true
}
}
集成router
-
安装
npm install vue-router@4 -
创建router/index.ts文件
import { createRouter, createWebHashHistory, RouteRecordRaw } from 'vue-router'
import HelloWorld from '@/components/HelloWorld.vue'
const routes: Array<RouteRecordRaw> = [
{
path: '/',
name: 'home',
component: HelloWorld
}
]
const router = createRouter({
history: createWebHashHistory(),
routes
})
export default router
-
在main.ts中导入使用
import router from './router/index'app.use(router)
如果以模块（module）的形式使用router
-
在router中创建module目录
-
在module中创建一个模块的router文件
如：setting.ts
import type { RouteRecordRaw } from 'vue-router';
const routes: RouteRecordRaw[] = [
{
component: () => import('@/pages/Settting.vue'),
path: '/setting',
redirect: { name: 'authority' },
children: [
{
path: 'authority',
name: 'Authority',
component: () => import('@/pages/settting/Authority.vue'),
},
{
path: 'userList',
name: 'UserList',
component: () => import('@/pages/settting/UserList.vue'),
},
],
},
];
export default routes;
- 在router目录下创建index.ts文件，并导入模块
import type { RouteRecordRaw } from 'vue-router';
import { createRouter, createWebHashHistory } from 'vue-router';
// vite2
const routes: RouteRecordRaw[] = [];
const modules = import.meta.globEager('./module/*.ts');
for (const path in modules) {
routes.push(...modules[path].default);
}
const router = createRouter({
history: createWebHashHistory(),
routes: routes,
});
export default router;
这段代码的意思是获取当前module文件夹下的所有ts结尾的文件自动导入
const modules = import.meta.globEager('./module/*.ts'); for (const path in modules) { routes.push(...modules[path].default); }相当于在webpack中的这段代码
// 参数：1. 目录 2. 是否加载子目录 3. 加载的正则匹配 const importFn = require.context('./module/', false, /\.ts$/) importFn.keys().forEach(key => { const rt = importFn(key).default routes.push(rt); })
集成vuex
- 安装
npm install vuex@next --save
- 创建store/index.ts文件
// store.ts
import { InjectionKey } from 'vue'
import { createStore, useStore as baseUseStore, Store } from 'vuex'
export interface State {
count: number
}
export const key: InjectionKey<Store<State>> = Symbol()
export const store = createStore<State>({
state: {
count: 0
},
mutations: {
setCount(state: State, count: number) {
state.count = count;
}
},
getters: {
getCount(state: State) {
return state.count
}
}
})
// 定义自己的 `useStore` 组合式函数
export function useStore() {
return baseUseStore(key)
}
- 在main.ts中导入
import { store, key } from './store/index'
app.use(store, key)
推荐使用pinia，不再使用vuex
使用sass
- 安装
npm install -D sass
- 配置公共变量
在vite.config.js文件中添加
css:{
preprocessorOptions: {
scss: {
additionalData: `@import "style/_style.scss";`
}
}
}
集成Axios
安装npm install axios
创建request.ts
import axios from 'axios';
// 里面就是定义了一些常量 NO_PERMISSION=401 ；OK_CODE=200
import { NO_PERMISSION, OK_CODE } from '@/app/keys';
import router from '@/router';
// 可以从其他文件导入的
export interface UserInfo {
id: number;
username: string;
role: string;
email: string;
token: string;
}
const requests = axios.create({
baseURL: import.meta.env.VITE_API_URL,
timeout: 10000,
});
//拦截器
requests.interceptors.request.use((config) => {
config = config || {};
//pinia
try {
const user = JSON.parse(localStorage.getItem('user') || '') as UserInfo;
if (user.token) {
config.headers!['Authorization'] = `Bearer ${user.token}`;
}
} catch (e) {}
return config;
});
requests.interceptors.response.use(
(resp) => {
const { code, msg } = resp.data || {};
if (code !== OK_CODE) {
return Promise.reject(msg);
}
if (code === NO_PERMISSION) {
router.push({ name: 'Login' }).then();
return Promise.reject(msg);
}
return Promise.resolve(resp);
},
(error) => {
return Promise.reject(error);
}
);
export default requests;
这里有用到import.meta.env.VITE_API_URL,这是vite提供的用于区分开发和生产环境的
在根目录创建.env和.env.production分别表示开发时变量和生产时变量
# .env
VITE_API_URL=http://localhost:3031
# .env.producttion
VITE_API_URL=http://localhost:1212
创建useHttp.ts
import { Method } from 'axios';
import requests from '@/api/requests';
export interface HTTPConfig {
url: string;
method: Method;
data?: { [key: string]: unknown };
params?: { [key: string]: unknown };
}
const useHttp = <T>(config: HTTPConfig): Promise<T> => {
return new Promise<T>((resolve, reject) => {
requests({
url: config.url,
method: config.method,
data: config.data || {},
params: config.params || {},
})
.then((resp) => {
resolve(resp.data);
})
.catch((err) => {
reject(err);
});
});
};
export default useHttp;
编写接口文件
import useHttp from '@/api/useHttp';
import { BasicResp } from '@/api/types';
// BasicResp 是返回数据的外层通用的类型
export interface BasicResp<T> {
code: number;
data: T;
msg: string;
}
export interface RegParams {
username: string;
password: string;
email: string;
}
export const reqUserRegister = (params: RegParams) => {
//axios http
return useHttp<BasicResp<null>>({
url: `/v1/user`,
method: 'post',
});
};
export interface LoginParams {
username: string;
password: string;
}
export interface LoginData {
info: UserInfo;
token: string;
}
export const reqUserLogin = (params: LoginParams) => {
//axios http
return useHttp<BasicResp<LoginData>>({
url: `/v1/user/login`,
method: 'post',
data: { ...params },
});
};
