create a http server with a connect route in javascript

To create an HTTP server with a connect route in Javascript, we can use the Node.js built-in http module along with the connect package. Here's an example implementation:

index.tsx
const http = require('http');
const connect = require('connect');

const app = connect();

app.use('/hello', (req, res, next) => {
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World!'); 
});

// Create server
const server = http.createServer(app);

// Listen on port 8080
server.listen(8080, () => {
  console.log('Server running on port 8080');
});

In the above code, we first require the http and connect modules. We then create a connect app and define a route for "/hello". Whenever a request matches the "/hello" route, the function passed to app.use() will be executed.

Inside the route function, we set the content-type header of the response to "text/plain", and send a simple "Hello World!" message as the response.

Finally, we create a server using the http module, passing in our connect app as the request handler, and listen on port 8080.

Once the server is running, you can access the "Hello World!" message by navigating to "http://localhost:8080/hello" in your web browser.
