Delete a Book By ID (DELETE)
To delete a specific book, you send a request to the API with the book’s unique ID. The API then identifies the book with that ID in the database and removes it.
Javascript
// Delete a book by IDapp.delete('/books/:id', async (req, res) => { try { const book = await Book.findByIdAndDelete(req.params.id); if (!book) { return res.status(404) .json({ error: 'Book not found' }); } res.json({ message: 'Book deleted successfully' }); } catch (error) { res.status(500) .json({ error: error.message }); } }); |
Example: Below is the Complete Example of MongoDB CRUD operations we have discussed above:
Javascript
require('dotenv').config();const express = require('express');const mongoose = require('mongoose');const Book = require('./models/book');const app = express();const URI = process.env.MONGODB_URImongoose.connect(URI)const database = mongoose.connectiondatabase.on('err', (err) => { console.log(err)})database.once('connected', () => { console.log('Database Connected to the server'); })app.use(express.json())app.get('/', (req, res) => { res.send('Welcome to the Books API!');});// Create a new bookapp.post('/books', async (req, res) => { try { const book = new Book(req.body); await book.save(); res.status(201).json(book); } catch (error) { res.status(400) .json({ error: error.message }); }});// Get all booksapp.get('/books', async (req, res) => { try { const books = await Book.find(); res.json(books); } catch (error) { res.status(500) .json( { error: error.message } ); }});// Update a book by IDapp.put('/books/:id', async (req, res) => { try { const book = await Book.findByIdAndUpdate( req.params.id, req.body, { new: true } ); if (!book) { return res.status(404) .json({ error: 'Book not found' }); } res.json(book); } catch (error) { res.status(500).json({ error: error.message }); }});// Delete a book by IDapp.delete('/books/:id', async (req, res) => { try { const book = await Book.findByIdAndDelete(req.params.id); if (!book) { return res.status(404) .json({ error: 'Book not found' }); } res.json({ message: 'Book deleted successfully' }); } catch (error) { res.status(500) .json({ error: error.message }); } });app.listen(3000, (req, res) => { console.log('Server is listening on port 3000');}); |
