探索听书世界的奥秘，源码背后的故事是什么？

创建一个听书应用的源码涉及多个方面，包括前端、后端和数据库，这里我将提供一个简化版的示例，以帮助你了解基本结构和实现方法。

技术栈

前端：HTML, CSS, JavaScript (使用React.js)

后端：Node.js with Express

数据库：MongoDB

前端代码 (client/src/App.js)

import React from 'react';
import './App.css';
import BookList from './components/BookList';
import { BrowserRouter as Router, Route } from 'reactrouterdom';
function App() {
  return (
    <Router>
      <div className="App">
        <Route path="/" component={BookList} />
      </div>
    </Router>
  );
}
export default App;

前端组件 (client/src/components/BookList.js)

import React, { useEffect, useState } from 'react';
import axios from 'axios';
const BookList = () => {
  const [books, setBooks] = useState([]);
  useEffect(() => {
    axios.get('http://localhost:5000/api/books')
      .then(response => setBooks(response.data))
      .catch(error => console.error('Error fetching data:', error));
  }, []);
  return (
    <div>
      <h1>Book List</h1>
      <ul>
        {books.map(book => (
          <li key={book._id}>{book.title}</li>
        ))}
      </ul>
    </div>
  );
}
export default BookList;

后端代码 (server/app.js)

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('bodyparser');
const cors = require('cors');
const bookRoutes = require('./routes/bookRoutes');
const app = express();
// Connect to MongoDB
mongoose.connect('mongodb://localhost:27017/listen_books', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => console.log('Connected to MongoDB'))
  .catch(err => console.error('Could not connect to MongoDB...', err));
app.use(cors());
app.use(bodyParser.json());
app.use('/api/books', bookRoutes);
const port = process.env.PORT || 5000;
app.listen(port, () => console.log(Listening on port ${port}...));

数据模型 (server/models/book.js)

const mongoose = require('mongoose');
const bookSchema = new mongoose.Schema({
  title: { type: String, required: true },
  author: { type: String, required: true },
  description: { type: String, required: true },
  fileUrl: { type: String, required: true } // URL to the audio file
});
module.exports = mongoose.model('Book', bookSchema);

API路由 (server/routes/bookRoutes.js)

const express = require('express');
const router = express.Router();
const Book = require('../models/book');
// Get all books
router.get('/', async (req, res) => {
  try {
    const books = await Book.find();
    res.json(books);
  } catch (err) {
    res.status(500).json({ message: err.message });
  }
});
// Add more routes here for CRUD operations (POST, PUT, DELETE) if needed
module.exports = router;

启动脚本 (listen_books.sh)

#!/bin/bash
Start the client in development mode
cd client && npm start &
Start the server in development mode
cd ../server && nodemon app.js &

安装依赖

在项目的根目录下运行以下命令来安装依赖：

npm install

这个简化版的听书应用只包含最基本的功能，即从MongoDB获取书籍列表并在前端展示，你可以根据需要扩展功能，比如添加用户认证、上传音频文件等。
