Solved: how to send html file with express

The main problem related to sending HTML files with Express is that Express does not natively support serving static files such as HTML, CSS, and JavaScript. To serve static files, you must use a middleware such as express.static() or the express.static middleware provided by the serve-static package. This middleware will allow you to specify a directory where your static files are located and then map requests for those files to that directory.

To send an HTML file with Express, you can use the res.sendFile() method. This method takes the path of the file as its argument and sends it to the client.

app.get('/', (req, res) => { 
   res.sendFile(__dirname + '/index.html'); 

1. app.get(‘/’, (req, res) => {
// This line defines a route handler for the root path of the application. When a request is made to the root path, this callback function will be executed with req and res objects as its arguments.

2. res.sendFile(__dirname + ‘/index.html’);
// This line uses the Express method sendFile() to send an HTML file located at __dirname + ‘/index.html’ to the client as a response to their request for the root path of the application

What is a HTML file

A HTML file is a Hypertext Markup Language file, which is used to create webpages. HTML files are made up of tags and attributes that define the structure and content of a webpage. They are written in plain text, so they can be opened and edited with any text editor.

About ExpressJS

ExpressJS is a web application framework for Node.js, released as free and open-source software under the MIT License. It is designed for building web applications and APIs. It has been called the de facto standard server framework for Node.js.

ExpressJS provides a robust set of features to develop web and mobile applications. It simplifies the process of routing requests, managing middleware, rendering HTML pages and sending responses to the client side. ExpressJS also provides support for template engines like Jade, EJS and Handlebars.

The ExpressJS framework is based on JavaScript and uses an MVC (Model-View-Controller) architecture pattern that helps developers create scalable applications with ease. Additionally, it allows developers to use multiple databases such as MongoDB, Redis, MySQL etc., which makes it easier to build complex applications.
