I need to develop an backend service of sending details of comic book. The project only has backend and no frontendI have made APIs for adding , getting and deleting the dataBut i don't know how to edit details using patch request when there is no frontendMy idea is to send request like this->
localhost3000/editcomic/:_comicID/{send the body}The body is the input in Postman which i want to sendLike if i want to change the year then i will send
{"year" : "1960}}By sending this only year will change and nothing elseHow can i do this?
comic_routes.js file
const express = require('express');const app = express();const router = express.Router();const mongoose = require("mongoose");const ComicModel = mongoose.model("ComicModel");const bodyparser = require('body-parser');const { ObjectId } = require('mongodb');/*assuming an express app is declared here*/app.use(bodyparser.json());app.use(bodyparser.urlencoded({extended: true}));router.post("/addcomic", (req, res) => { const { book, author, year , price , discount , pages , condition , description , comments } = req.body; if (!book || !author || !year) { return res.status(400).json({ error: "One or more mandatory fields are empty" }); } const comicObj = new ComicModel({ book: book, author: author, year: year , price : price , discount: discount , pages : pages , condition : condition , description : description , comments : comments}); comicObj.save() .then((newComic) => { res.status(201).json({ comic: newComic }); }) .catch((error) => { console.log(error); })});router.get("/getcomics", (req, res) => { ComicModel.find() .then((dbComics) => { res.status(200).json({ comics: dbComics }) }) .catch((error) => { console.log(error); })});router.delete("/deletecomic/:comicId", (req, res) => { ComicModel.findOne({ _id: req.params.comicId }) .populate("_id") .exec((error, comicFound) => { if (error || !comicFound) { return res.status(400).json({ error: "Comic does not exist" }); } comicFound.remove() .then((data) => { res.status(200).json({ result: data }); }) .catch((error) => { console.log(error); }) })});module.exports = router;
