Request Data Handling in Express.js | req.params, req.query, req.body Explained | CRUD API
In this video, we will learn Request Data Handling in Express.js in a very simple way. If you are building APIs using Express, understanding how the server receives data from the client is extremely important.
We will understand three important parts of the request object in Express:
• req.params – used to get values from URL parameters
• req.query – used to read query parameters from the URL
• req.body – used to receive data sent in the request body
Along with the theory, we will also build a simple CRUD API using a memory array so you can see how these concepts are used in real backend applications.
This video is perfect for beginners learning Node.js and Express.js, and everything is explained in very simple English with practical examples.
By the end of this video, you will clearly understand how servers receive and process data from clients when building APIs.
