基于微前端架构的企业级应用平台
开发一个基于微前端架构的企业级应用平台,包含以下功能:
// 主应用示例 (React + single-spa)
import React from 'react';
import ReactDOM from 'react-dom/client';
import singleSpaReact from 'single-spa-react';
import { registerApplication, start } from 'single-spa';
import AuthService from './services/auth-service';
import { BrowserRouter as Router } from 'react-router-dom';
// 初始化认证服务
const authService = new AuthService();
// 主应用根组件
const rootComponent = ({ isAuthenticated, user }) => (
{/* 微前端应用将在这里渲染 */}
);
// 注册主应用
const reactLifecycles = singleSpaReact({
React,
ReactDOM,
rootComponent,
errorBoundary(err, info, props) {
// 错误边界处理
return Error: {err.message};
},
});
// 注册微前端应用
function registerMicrofrontends() {
// 注册用户管理微应用
registerApplication({
name: 'user-management',
app: () => System.import('user-management'),
activeWhen: ['/users'],
customProps: {
authService,
},
});
// 注册产品管理微应用
registerApplication({
name: 'product-management',
app: () => System.import('product-management'),
activeWhen: ['/products'],
customProps: {
authService,
},
});
// 注册订单管理微应用
registerApplication({
name: 'order-management',
app: () => System.import('order-management'),
activeWhen: ['/orders'],
customProps: {
authService,
},
});
}
// 启动应用
registerMicrofrontends();
start();
// 导出生命周期函数
export const bootstrap = reactLifecycles.bootstrap;
export const mount = reactLifecycles.mount;
export const unmount = reactLifecycles.unmount;
// 微应用示例 (Vue + single-spa)
import Vue from 'vue';
import singleSpaVue from 'single-spa-vue';
import App from './App.vue';
import router from './router';
import store from './store';
import { BootstrapVue, IconsPlugin } from 'bootstrap-vue';
import 'bootstrap/dist/css/bootstrap.css';
import 'bootstrap-vue/dist/bootstrap-vue.css';
// 使用BootstrapVue
Vue.use(BootstrapVue);
Vue.use(IconsPlugin);
// 禁用生产提示
Vue.config.productionTip = false;
// 创建微前端生命周期
const vueLifecycles = singleSpaVue({
Vue,
appOptions: {
render: (h) => h(App),
router,
store,
// 接收来自主应用的props
props: ['authService'],
},
});
// 导出生命周期函数
export const bootstrap = vueLifecycles.bootstrap;
export const mount = vueLifecycles.mount;
export const unmount = vueLifecycles.unmount;
// 共享认证服务
class AuthService {
constructor() {
this.token = localStorage.getItem('token');
this.user = JSON.parse(localStorage.getItem('user'));
}
// 登录方法
async login(username, password) {
try {
const response = await fetch('/api/auth/login', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({ username, password }),
});
const data = await response.json();
if (response.ok) {
this.token = data.token;
this.user = data.user;
// 存储到localStorage
localStorage.setItem('token', this.token);
localStorage.setItem('user', JSON.stringify(this.user));
return true;
} else {
throw new Error(data.message || '登录失败');
}
} catch (error) {
console.error('登录错误:', error);
throw error;
}
}
// 登出方法
logout() {
this.token = null;
this.user = null;
// 从localStorage移除
localStorage.removeItem('token');
localStorage.removeItem('user');
}
// 检查是否已认证
isAuthenticated() {
return !!this.token;
}
// 获取当前用户
getUser() {
return this.user;
}
// 获取认证头
getAuthHeader() {
return this.token ? { Authorization: `Bearer ${this.token}` } : {};
}
// 检查权限
hasPermission(permission) {
if (!this.user || !this.user.permissions) {
return false;
}
return this.user.permissions.includes(permission);
}
}
export default AuthService;
// 共享组件库 - Button.vue
