Express.js App Delete Method

The app.delete() method routes all the HTTP DELETE requests to the specified path with the specified callback functions.

Syntax

app.delete(path, callback, [callback])

Parameters

• path − This is the path for which the middleware function is invoked. A path can be a string, path pattern, a regular expression, or an array of all these.
• callback − These are the middleware functions or a series of middleware functions that act like a middleware except that these callbacks can invoke next (route).

Example 1

Create a file "appDelete.js" and copy the following code snippet. After creating the file, use the command "node appDelete.js" to run this code.

// app.delete() Method Demo Example

// Importing the express module
const express = require('express');

// Initializing the express and port number
var app = express();
// Initializing the router from express
var router = express.Router();
var PORT = 3000;

// Creating a DELETE request
app.delete('/api', (req, res) => {
   console.log("DELETE Request Called for /api endpoint")
   res.send("DELETE Request Called")
})

// App listening on the below port
app.listen(PORT, function(err){
   if (err) console.log(err);
   console.log("Server listening on PORT", PORT);
});

Hit the following Endpoint with a DELETE request

•  http://localhost:3000/api

// app.delete() Method Demo Example

// Importing the express module
const express = require('express');

// Initializing the express and port number
var app = express();
// Initializing the router from express
