Elm Copenhagen Meetup March 2016

HTTP Requests / JSON Decoding task

Battleships

Batleships Game Server

(IP will be provided at the meetup)

Exercise

Build a battleship game client that will allow a player to:

• Create a new game
• Join existing game
• See the board grid (10 x 10)
• Fire shots at a grid location and see the result of the shot
• See a list of on-going games
• See details of a given game

You can start with simple Http Task, see the example in SimpleTask.elm.

Then you can move on to use StartApp, which there are some skeleton files in this repo (Main.elm, Game.elm and Board.elm - but they do not compile)

Getting started

git clone https://github.com/elmcph/battleships-client.git
cd battleships-client
npm install
export PATH=$PATH:./node_modules/.bin  # Or equivalent on Windows
# Edit SimpleTask.elm and enter the Battleships game server host/port
elm-live  SimpleTask.elm

Open [http://localhost:8000]

Local reload servers:

This example uses elm-live to compile and auto-reload. You could also use elm-server
