How To Host NodeJS Server on Localhost using  Termux?

 

 

Once you create your website, or design your website using HTML & CSS, you can use NodeJS to connect it with your localhost server.

But to host it on your localhost, you need to install another server package called “http-server”. This simple server package will host your website on your localhost. To install this package you need to use the following npm command on your termux:

npm install -g http-server

Remember, the name of your HTML file must be ‘index.html’ to host using this package.

How To Host NodeJS Server on Localhost using  Termux?

Down below, I have given a simple example of how you can host a HTML website on your localhost using NodeJS & Termux.

Let’s create a simple JavaScript program:

1. Create a JS file that will connect our html script with the server. Use the following nano command to create the file:

nano server.js

2. Now paste following JavaScript program in the ‘server.js’ file:

Javascript:

const http = require('http'); 
const fs = require('fs'); 

const server = http.createServer((req, res) => {
const htmlFile = fs.readFileSync('index.html', 'utf-8'); 
res.writeHead(200, { 'Content-Type': 'text/html' }); 
res.end(htmlFile); }); 

server.listen(3000, '127.0.0.1'); 
console.log('Server running at http://127.0.0.1:3000/');

 

How To Host Your Website on Localhost using  NodeJS & Termux?

3. Create an HTML program to design our Website. The name for this file should be index.html. Use  the command:

nano index.html

4. Now, paste the following simple html code in the index.html file:

HTML

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<meta name="viewport" content="width=device-width, initial-scale=1.0"> 
<title>Node.js on Termux</title> 
</head> 
<body> 
<h1>Hello from Node.js on Termux!</h1> 
</body> 
</html>

5. Now once you complete all the previous steps, you are ready to host your website on your localhost. Hit the following command to do it.

node server.js

This command will quickly start your server on your localhost (http://127.0.0.1/) & obviously it will show the port on your termux, and in most of the cases, it is 3000.

6. Now to access your website, open a browser like Chrome, Brave, Opera etc, and enter the following credential on the search box:

http://localhost:3000
