expressjsHow can I use Express.js with TypeScript?

Express.js is a popular Node.js web application framework that can be used with TypeScript for creating web applications.

To use Express.js with TypeScript, you need to first install the necessary packages:

npm install express @types/express

Then, create a TypeScript file, such as app.ts:

import express from 'express';

const app = express();

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

app.listen(3000, () => {
  console.log('Server started!');
});

Finally, compile the TypeScript file to JavaScript and run it:

tsc app.ts
node app.js

Output example

Server started!

The code above is a basic example of how to use Express.js with TypeScript. It creates a web server that listens for requests on port 3000 and responds with "Hello World" when a request is made to the root path.

More information about using Express.js with TypeScript can be found in the official Express.js documentation and the TypeScript Express tutorial.
