构建智能预约体验：深度解析预约系统源码的代码精髓

随着数字化时代的发展，预约系统在各行业中扮演着越来越重要的角色。本文将深入研究预约系统源码，通过代码示例分析其技术要点，为开发者提供实用的指导，助力构建智能、高效的预约体验。

技术栈综述

预约系统源码采用了现代化的技术栈，主要包括前端使用React框架，后端采用Node.js和Express框架，而数据库则选择MongoDB。以下是源码中的核心代码示例：

前端代码（React）

// AppointmentForm.js
import React, { useState } from 'react';const AppointmentForm = ({ addAppointment }) => {const [name, setName] = useState('');const [date, setDate] = useState('');const handleSubmit = e => {e.preventDefault();if (name && date) {addAppointment({ name, date });setName('');setDate('');}};return (<form onSubmit={handleSubmit}><label>Name:</label><input type="text" value={name} onChange={e => setName(e.target.value)} /><label>Date:</label><input type="date" value={date} onChange={e => setDate(e.target.value)} /><button type="submit">预约</button></form>);
};export default AppointmentForm;

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());mongoose.connect('mongodb://localhost:27017/appointments', { useNewUrlParser: true, useUnifiedTopology: true });const appointmentSchema = new mongoose.Schema({name: String,date: Date,
});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}`);
});
