Update a Book By ID (PUT)

GET Request:

Delete a Book By ID (DELETE):

When you want to update a specific book, you provide the book’s unique ID along with the new data in the request. The API then locates the book with the given ID in the database and replaces its existing information with the new data.

Javascript




// Update a book by ID
app.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 });
    }
});
