Setting Request Handlers
A Web Server receives Requests, processes them, and returns a Response. We need to establish route handling in our application to handle these Requests.
When developing modern applications we expose what are called ReSTful web services. These Requests are a GET request that gets data, a POST request that sends data securely, a PUT request that updates data, and a DELETE request that deletes data.
As well as deciding on the Requests, we also need to decide on we will respond with a Response to Requests.
Let's create a simple GET request that says "hello world"
app.get("/sayhello", (req, res, next) =>
{
res.writeHead(200, {'Content-Type': 'text/html'});
res.send("Hello World");
});
