expressjsHow can I use Express.js with ESM in my project?

Express.js is a popular web application framework for Node.js. It is used to create APIs, web applications, and server-side applications. ESM (ECMAScript Modules) is a language-level module system that enables developers to use import and export statements in their code.

To use Express.js with ESM in a project, the following steps should be taken:

1. Install the esm package:

npm install esm

2. Create a index.js file and import the express package:

import express from 'express';

3. Create an instance of the express application:

const app = express();

4. Add routes to the application:

app.get('/', (req, res) => {
  res.send('Hello World!');
});

5. Start the server:

app.listen(3000, () => {
  console.log('Server is listening on port 3000');
});

6. Run the project with the esm package:

node -r esm index.js

The output should be:

Server is listening on port 3000

This is the basic setup for using Express.js with ESM in a project. For more information, please refer to the following links:
