Required steps to render HTML file in express JS

Step 1:- Load the express JS module of node JS with the help of the const keyword as shown below.

const express = require('express');

Step 2:- Now, call the express() method to use the packages and functionalities of express JS and assigned it to a new variable called ‘data’ as shown below.

const data = express();

Step 3:- Next, we will initialize the path module of Node JS using the const keyword as shown below.

const path = require('path');

Please note that by using the path module we can get the path of any file or folder location.

Step 4:- Now, we will use the path module to get the path of the root directory of the project with the help of the join() method as shown below.

const publicPath = path.join(__dirname);

On the above line of code, join(__dirname) is used to get the path of the project directory.

Step 5:- Now, create a public folder under the root directory of the project as shown below.

Step 6:- Now, we can access the path of the public folder inside the project directory by passing “public” as a second argument within the join() method as shown below.

const publicPath = path.join(__dirname,'public');

Step 7:- Create a simple HTML file inside the public folder as shown below.


<title>About US</title>
<h2>Welcome to about us page</h2>

Step 8:- Next, we will use the static() function of express JS modules and pass the publicPath as a parameter inside the static() function to access all the HTML files that exist in the public folder as given below.


Complete Code:- (express.js)

const express = require('express');
const data = express();
const path = require('path');
const publicPath = path.join(__dirname,'public');

Step 9:- Go to your browser URL and type http://localhost:3000/about.html and press ENTER.

Step 10:- You will see the HTML file output as shown below.

Conclusion:- I hope this tutorial will help you to understand the concept. If there is any doubt then please leave a comment below.
