[JITERA] Add PATCH /books/:id route to bookRoutes

Created by: chi-jitera

Overview

This pull request introduces a new PATCH endpoint for updating specific fields of a book resource. The new route is added to the existing book routes to enhance the API's functionality.

Changes

• Updated /routes/bookRoutes.js:
  • Added the PATCH route for /books/:id using the bookController.patchBook method.
  • The new route is placed logically between the PUT and DELETE routes to maintain a clear structure for HTTP methods related to resource updates.

Code Changes

const express = require('express');
const bookController = require('../controllers/bookController'); 
const router = express.Router(); 

router.post('/books', bookController.createBook);
router.get('/books', bookController.getAllBooks);
router.get('/books/search', bookController.searchBooks);
router.get('/books/:id', bookController.getBookById);
router.put('/books/:id', bookController.updateBook); // Added PATCH route
router.patch('/books/:id', bookController.patchBook); // New PATCH route
router.delete('/books/:id', bookController.deleteBook); 

module.exports = router;

This addition allows clients to partially update book resources, improving the flexibility of the API.
