YouVote

all the basic stuff is working - users can create polls, vote to them (only once per IP) and show the stats after they cast a vote

This was both a nice and a surprising hard thing to do - I learned a lot and think I'll actually use servant for my hobby projects in the future.

For production? Well nope - things like elm-export have issues that don't get updated/uploaded to hackage often, servant itself has no great answer to restful redirects (it's not part of the type - you do it by throwing errors)

getting started

if you have a bash shell available you can just use the

./make.sh

script to get started - if not just follow these steps:

make

alternatively there is an Makefile included so

make server-start

should compile everything and then fire up the server

building the server app

the first step is to get the Haskell appliction compiled:

stack build

of course you want to have stack installed for this.

Also this could take quite some time if you don't have the dependencies cached alread - so maybe get a coffee.

generating the servant-api for elm

next we need have servant generate the api.elm for us:

stack exec YouVote-codeGen

this should give you src/client/api.elm

compiling the elm application

now we can let elm generate the static/js/client.js for us:

cd src/client
elm make Main.elm --output ../../static/js/client.js
cd ../..

all done

starting

just do

stack exec YouVote

this should start a server at localhost:8080
