在当今数字化时代，预约系统的重要性日益凸显，而预约系统源码的开放将为各行业带来更加灵活、智能的预约解决方案。本文将深入探讨预约系统源码的技术内幕，为开发者提供实用的代码示例，助力打造智能定制化的预约服务。

技术栈概览

预约系统源码采用了现代化的技术栈，其中包括前端使用React框架，后端采用Node.js和Express框架，而数据库则选用MongoDB。以下是源码的简单结构示例：

前端代码（React）

// App.js
import React, { useState, useEffect } from 'react';
import AppointmentForm from './AppointmentForm';
import AppointmentList from './AppointmentList';
import './App.css';const App = () => {const [appointments, setAppointments] = useState([]);useEffect(() => {// Fetch appointments from the server// Example API call using fetch:fetch('/api/appointments').then(response => response.json()).then(data => setAppointments(data)).catch(error => console.error('Error fetching appointments:', error));}, []);const addAppointment = newAppointment => {// Send new appointment to the serverfetch('/api/appointments', {method: 'POST',headers: {'Content-Type': 'application/json',},body: JSON.stringify(newAppointment),}).then(response => response.json()).then(data => setAppointments([...appointments, data])).catch(error => console.error('Error adding appointment:', error));};return (<div className="app-container"><h1>预约系统</h1><AppointmentForm addAppointment={addAppointment} /><AppointmentList appointments={appointments} /></div>);
};export default App;

后端代码（Node.js + Express）

// server.js
const express = require('express');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
const app = express();
const port = 3001;app.use(bodyParser.json());// Connect to MongoDB (replace 'mongodb://localhost:27017/appointments' with your MongoDB connection string)
mongoose.connect('mongodb://localhost:27017/appointments', { useNewUrlParser: true, useUnifiedTopology: true });const appointmentSchema = new mongoose.Schema({name: String,date: Date,// Add more fields as needed
});const Appointment = mongoose.model('Appointment', appointmentSchema);app.get('/api/appointments', async (req, res) => {const appointments = await Appointment.find();res.json(appointments);
});app.post('/api/appointments', async (req, res) => {const newAppointment = new Appointment(req.body);const savedAppointment = await newAppointment.save();res.json(savedAppointment);
});app.listen(port, () => {console.log(`Server is running on port ${port}`);
});
