import { scheduleJob } from 'node-schedule';
// 定时任务
function setupScheduledTasks() {
// 每6秒执行一次
setInterval(() => {
taskEverySixSeconds();
}, 6000);
// 每33分钟执行一次
setInterval(() => {
taskEveryThirtyThreeMinutes();
}, 33 * 60 * 1000);
// 每天的1点到5点之间执行
scheduleJob('0 * 1-5 * * *', taskEarlyMorning);
}
// 示例任务函数
function taskEverySixSeconds() {
console.log('Running task every 6 seconds');
}
function taskEveryThirtyThreeMinutes() {
console.log('Running task every 33 minutes');
}
function taskEarlyMorning() {
console.log('Running early morning task');
}
// 在main函数中调用
setupScheduledTasks();
app.all('/*', (req, res) => {
res.setHeader('Access-Control-Allow-Origin', '*');
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE');
res.setHeader('Access-Control-Allow-Headers', 'Content-Type, Authorization');
if (req.method === 'OPTIONS') {

import { verifyToken } from './auth'; // 假设你有一个auth模块来处理token验证
app.use(json(), (req, res, next) => {
const token = req.header('Authorization')?.replace('Bearer ', '');
if (token) {
try {
const userInfo = verifyToken(token); // verifyToken应该返回用户信息或抛出错误
req.userInfo = userInfo; // 将用户信息写入请求对象

npm install node-schedule
npm install cors
在这个示例中，我使用了cors中间件来处理跨域请求，而不是手动设置CORS头。这是一个更简洁的方法，因为它会自动处理预请求（preflight）和其他CORS相关的复杂性。
确保你已经定义了taskEverySixSeconds，taskEveryThirtyThreeMinutes，和taskEarlyMorning函数，它们将包含你的业务逻辑。
同时，verifyToken函数应该是你在一个单独的文件中定义的，比如auth.ts，它接受一个token，验证它，并返回用户信息或抛出错误。这里的中间件会检查请求头中的Authorization字段，并尝试解析和验证token。如果验证成功，用户信息将被附加到req.userInfo。
import { serve } from 'hyperexpress';
import { connectToDatabase } from './db';
import { setupRoutes } from './routes';
import { json } from 'hyperexpress';
import { setInterval } from 'timers';
import schedule from 'node-schedule';
import cors from 'cors';
const app = serve();
// 跨域处理
app.use(cors({
origin: '*', // 或者配置具体的允许域名
methods: 'GET, POST, PUT, DELETE',
allowedHeaders: 'Content-Type, Authorization'
}));
app.use(json());
// Token验证中间件
app.use((req, res, next) => {
const token = req.headers.authorization?.split(' ')[1]; // 获取Bearer后面的Token
if (token) {
try {
const userInfo = verifyToken(token); // 假设verifyToken是一个解析Token并返回用户信息的函数
req.userInfo = userInfo; // 将用户信息写入请求对象
next();
} catch (error) {
res.status(401).json({ error: 'Invalid token' });
}
} else {
next(); // 如果没有Token，可以选择继续或者返回错误
}
});
// 设置路由
setupRoutes(app);
// 定时任务
function setupScheduledTasks() {
// 每6秒执行一次
setInterval(() => {
taskEverySixSeconds();
}, 6000);
// 每33分钟执行一次
setInterval(() => {
taskEveryThirtyThreeMinutes();
}, 33 * 60 * 1000);
// 每天的1点到5点之间执行
const rule = new schedule.RecurrenceRule();
rule.hour = [1, 5]; // 每天的1点到5点
rule.minute = 0; // 每小时的开始
schedule.scheduleJob(rule, taskEarlyMorning);
}
// 示例任务函数
function taskEverySixSeconds() {
console.log('Running task every 6 seconds');
// 你的业务逻辑
}
function taskEveryThirtyThreeMinutes() {
console.log('Running task every 33 minutes');
// 你的业务逻辑
}
function taskEarlyMorning() {
console.log('Running early morning task');
// 你的业务逻辑
}

npm install hyperexpress @deepkit/orm @deepkit/orm-postgres-driver pg // src/entity/User.ts import { Entity, PrimaryKey, Property } from '@deepkit/orm'; @Entity() export class User { @PrimaryKey() id: number; @Property() name: string; @Property() email: string; }

4. 创建服务
创建用户服务来处理业务逻辑：
// src/service/UserService.ts import { Repository } from '@deepkit/orm'; import { User } from '../entity/User'; export class UserService { userRepository: Repository<User>; constructor() { this.userRepository = connection.getRepository(User); } async createUser(userData: Partial<User>): Promise<User> { const user = this.userRepository.create(userData); await this.userRepository.persistAndFlush(user); return user; } async findAllUsers(): Promise<User[]> { return this.userRepository.find(); } async findUserById(id: number): Promise<User | null> { return this.userRepository.findOne({ id }); } async updateUser(id: number, updatedData: Partial<User>): Promise<User | null> { await this.userRepository.update(id, updatedData); return this.userRepository.findOne({ id }); } async deleteUser(id: number): Promise<void> { await this.userRepository.removeAndFlush({ id }); } }
// src/main.ts import { serve } from 'hyperexpress'; import { connectToDatabase } from './db'; import { setupRoutes } from './routes'; import { json } from 'hyperexpress'; const app = serve(); app.use(json()); // Set up routes setupRoutes(app); async function main() { await connectToDatabase(); await app.listen(3000); console.log('Server is running on port 3000'); } main();
// src/routes.ts import { app } from './app'; import { UserService } from './service/UserService'; import { json } from 'hyperexpress'; // Helper function to set up all routes export function setupRoutes(app: ReturnType<typeof serve>) { const userService = new UserService(); app.post('/users', async (req, res) => { try { const user = await userService.createUser(req.body); res.status(201).json(user); } catch (error) { res.status(500).json({ error: error.message }); } }); // ... Other route handlers // Add the rest of the route handlers here // ... app.get('/users', async (req, res) => { // ...

在 Node.js 项目中，dependencies 文件通常指的是项目的依赖列表，它会列出项目中所有需要用到的外部模块。这个依赖列表会被记录在项目根目录下的 package.json 文件中。 { "name": "my-nodejs-project", "version": "1.0.0", "description": "A sample Node.js project", "main": "app.js", "dependencies": { "express": "^4.17.1" } }
