Approach 1 Direct Usage in Express JS
In this approach, we leverage Express JS to handle nested routes and implement the DELETE method, providing a clear and straightforward organization of code.
Syntax:
app.delete('base URL', (req, res) => {
// DELETE method logic for the base URL
})
app.delete('base URL/Nested URL', (req, res) => {
// DELETE method logic for the nested URL
})
Example: Write the following code in server.js file.
Javascript
// Server.jsconst express = require('express');const app = express();const PORT = 3000;app.delete("/resource", (req, res) => { console.log("DELETE Request Successful!"); res.send("Resource Deleted Successfully");});app.delete("/resource/:id", (req, res) => { const resourceId = req.params.id; console.log(`Deleting resource with ID: ${resourceId}`); res.send(`Resource with ID ${resourceId} Deleted Successfully`);});app.listen(PORT, () => { console.log(`Server established at ${PORT}`);}); |
How to test DELETE Method of Express with Postman ?
The DELETE method in web development plays a crucial role in handling resource deletions on the server.
