Online, realtime, multiplayer game of Set, from Set Enterprises, Inc., built entirely with ocaml (and reasonml).
Play the game here: https://setml.andrewtongen.net/
Outside of the websocket connection, the app server processes are completely stateless. All messages are synchronized with postgresql using listen/notify.
Server-side ocaml code is found in src/server.
Client-side reasonml code is found in src/client.
Shared modules are found in src/shared.
On the client-side, all cards are rendered to a hidden canvas with svg, and then copied to the visible canvas to update the game board.
- ocaml 4.06.1
- dune
- opam
- npm
- make
- postgresql 11
- linux (untested on macos)
git clone [email protected]/atongen/setml
cd setml
Provision a postgres db for setml and create an envfile with the connection information.
The default values look similar to this:
DB_NAME=setml_development
DB_HOST=localhost
DB_PORT=5432
DB_USER=`whoami`
DB_PASS=abcd1234
Add entries only for what you need to override.
opam pin add -yn setml .
opam install setml
make
npm install
npm start
and in separate terminal:
npm run-script webpack
You may want to refer to https://reasonml.github.io/reason-react/docs/en/installation for more information about installing bucklescript/reasonml.
With db created, envfile in place, you can run
script/reload_db.sh
to load the database schema.
Then run:
script/run.sh
to start the server.
Browse to http://localhost:7777/ to access the application.
Provision a test database in postgres (this is setml_test by convention), then run:
SETML_ENV=test script/reload_db.sh
To populate the test db schema.
Then run
make test
To run the test suite against both the server-side code and client-side code.
Docker images are provided on dockerhub.
