Lab – Routing

Objective

Learn and practice routing using Node and Express.

Specification

Create a web server that

1. Accepts and processes request messages submitted from browser, and
2. Generates and sends response messages back to browser for display.

Your web server must be able to handle

1. URL with hostname and port
   1. Request message URL: 0.0.1:3000
   2. Response message: “SUCCESS!”
2. URL with hostname, port and path echo
   1. Request message URL: 0.0.1:3000/echo
   2. Response message: “SUCCESS! echo”
3. URL with hostname, port, path foxtrot and route parameter value kilo
   1. Request message URL: 0.0.1:3000/foxtrot/kilo
   2. Response message: “SUCCESS! Received kilo via foxtrot” where the value kilo must be retrieved via the route parameter
4. Invalid/unexpected URL
   1. Request message URL: 0.0.1:3000/<any other value>
   2. Response message: “FAILED! Fix your URL.”

Hostname 127.0.0.1 can be replaced by localhost.

Port number 3000 can be replaced by any other port number that is from 1024 (2^11) to 65535 (2^17 – 1) inclusive.

Tools

Use the following:

1. js
2. js
3. js router endpoint path
4. js req.params
5. GET request
