In this article, we'll delve into the response object in Node.js – a crucial aspect of server-side programming. The response object represents the writeable stream back to the client and provides essential information about the data being sent.
Understanding and mastering the response object allows you to fine-tune your server responses, ensuring a smooth user experience.
The response header provides the browser with information about the data type being sent. Here's how to set it:
1. Delete any console.logs.
2. Useresponse.setHeaderand specify the content type (e.g., JSON or HTML).
3. Send the desired data type to the browser usingresponse.write. For example, to send HTML:response.setHeader('Content-Type', 'text/html'); response.write('<h1>Welcome to Ck Mobile Task</h1>').
After setting the header, you can send data usingresponse.write. Here's an example:
```javascript
// Set up the response object
const response = {};
// Write a welcome message
response.write('Welcome to Ck Mobile Task');
// End the response
response.end();
```
To include dynamic content in your HTML pages, use the response object like so:
```javascript
// Set up the response object
const response = {};
// Define the HTML structure
n let html = '<!DOCTYPE html>
<html lang=
