express

app.get('/:character', (req, res) => { // !'/:variable means we return dynamic value
  // * creates a constant which stores return from request parameter character

  const chosen = req.params.character;

  // What does this log?
  // * console logs the above return from request
  console.log(req.params);
  console.log(chosen);
  // * ends function response
  res.json(chosen);
  res.end();
});
The following examples illustrate defining simple routes.

Respond with Hello World! on the homepage:
//get method for retrieving data.
app.get('/', function (req, res) {
  res.send('Hello World!')
})
 Save
Respond to POST request on the root route (/), the application’s home page:
//send method for sending data.
app.post('/', function (req, res) {
  res.send('Got a POST request')
})
 Save
Respond to a PUT request to the /user route:
//put request to 
app.put('/user', function (req, res) {
  res.send('Got a PUT request at /user')
})
 Save
Respond to a DELETE request to the /user route:

app.delete('/user', function (req, res) {
  res.send('Got a DELETE request at /user')
})
Basic routing
Routing refers to determining how an application responds to a client request to a particular endpoint, which is a URI (or path) and a specific HTTP request method (GET, POST, and so on).

Each route can have one or more handler functions, which are executed when the route is matched.

Route definition takes the following structure:

app.METHOD(PATH, HANDLER)
 Save
Where:

app is an instance of express.
METHOD is an HTTP request method, in lowercase.
PATH is a path on the server.
HANDLER is the function executed when the route is matched.
