Let’s create book using the Book model (POST)

Javascript




// Create a new book
app.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 });
    }
});
 






                        









																																						

																								

																										
We’ve implemented try-catch blocks to handle success and error messages. The use of async-await syntax ensures a structured and readable code style, allowing us to seamlessly wait for promises and enhancing error handling. This approach contributes to a cleaner and maintainable codebase for our Books API.

																																						

																								

																										
Now add data to the body in postman and send a POST request.
