Developing the game's web UI

Please start your favorite Julia editor and open the sixdegrees/ folder we used in the previous chapter. It should contain all the files that we've worked on already—six_degrees.jl, plus the Articles, Database, Gameplay, and Wikipedia modules.

Note

If you haven't followed through the code up to this point, you can download this chapter's accompanying support files, which are available at https://github.com/PacktPublishing/Julia-Programming-Projects/tree/master/Chapter05.

Add a new file for our web app. Since the code will be more complex this time and should integrate with the rest of our modules, let's define a WebApp module within a new WebApp.jl file. Then, we can add these first few lines of code:

module WebApp 
 
using HTTP, Sockets

const PORT = 8888 
const ROUTER = HTTP.Router() 
const SERVER = HTTP.Server(ROUTER) 
 
HTTP.serve(SERVER, HOST, PORT) 
 
end 

No surprises here—similar to the previous example, we define constants for...
