How To create Delete request api with Node js

How To create Delete request api with Node js

Creating a Delete Request API is a fundamental skill for backend developers. With Node.js, implementing such APIs can be efficient and scalable, catering to the needs of modern web applications. This blog, presented by CodexCoach, is designed to walk you through the process of creating a delete request API with Node.js.

Whether you’re a beginner or looking to brush up on your skills, this guide is packed with expert insights and actionable tips to enhance your learning experience.


In the realm of web development, APIs (Application Programming Interfaces) serve as the backbone, facilitating communication between different software applications. Specifically, a Delete Request API is crucial for enabling the removal of resources from a server.

With Node.js, known for its non-blocking I/O and event-driven architecture, creating efficient APIs is more accessible than ever.

Install Library in Project

First and foremost, setting up your Node.js environment is essential. Node.js comes with npm (Node Package Manager), which simplifies the process of managing libraries and dependencies.

For our project, we’ll need Express, a fast, unopinionated, minimalist web framework for Node.js, which is perfect for building APIs.

Run the following command in your project directory:

npm install express dotenv nodemon

Create server.js File

With the environment set up, it’s time to create the core of our API – the server.js file.

  1. Create the server.js file: In your project directory, create a file named server.js. This file will serve as the entry point for our application.
  2. Set up the Express server: Add the following code to server.js to initialize your Express server and define a delete request handler:
// Express.js Application for managing user data
const express = require("express");
const app = express();


const port = process.env.PORT || 3000;

// Assuming 'app' is an instance of Express
app.delete("/:id", (req, response) => {
 pool.query(`DELETE FROM users WHERE id = ?`,, (err, result) => {
   if (err) {
     console.log("error: ", err);
     response.status(400).json({ result: false, message: err });
   if (result.affectedRows === 0) {
     response.status(400).json({ result: false, message: "User not found" });
   } else {
     console.log("user delete: ", result);
       result: true,
       answer: result,
       message: `User Delete sucessfully id:- ${}`,

// Start the server
app.listen(port, () =>
 console.log(`Example app listening at http://localhost:${port}`)

3. This code snippet demonstrates a basic setup where our server listens on port 3000 and defines a route for delete requests. The /item/:id route is designed to handle the deletion of an item identified by its id.

How to Run Get Request API in Postman or Chrome or Else Application

Testing your API is an integral part of the development process. Postman is a powerful tool for testing APIs, allowing you to send requests and analyze responses without the need for a frontend interface.

1.Install Postman: Download and install Postman from their official website.

2.Open Postman: Launch Postman and create a new request by clicking the “New” button, then select “Request”.

3.Configure the Request: In the request tab:

  • Set the method to “DELETE”.
  • Enter the URL of your API endpoint. For our example, it would be http://localhost:3000/, assuming you’re deleting an item with an ID of 1.
Method :- Delete
id :- [you have to add id]
Api :- http://localhost:3000/,

4.Send the Request: Click the “Send” button. If everything is set up correctly, you should receive a response indicating the item was deleted successfully.

    This process demonstrates how to test your Delete Request API, ensuring its functionality before integration with frontend applications or deployment.

    Whether you’re building APIs for personal projects, educational purposes, or professional applications, the skills you’ve learned today are invaluable. The beauty of Node.js and Express lies in their versatility and community support, offering a plethora of libraries and tools to enhance your development process further.

    Thank you for choosing this guide to enhance your skills. Happy coding, and may your APIs be efficient, secure, and, above all, impactful.
