A small webapp to convert Magic: the Gathering decks into a format acceptable by Tabletop Simulator

This builds an executable, ttsmagic-server, that serves a webapp that converts Magic: the Gathering decks listed online elsewhere into Tabletop Simulator decks.

Building

The shell.nix environment includes a Rust installation that's capable of building both the server and frontend. cargo build and cargo run should both work, though the latter may require a few environment variables set before anything useful happens.

Deployment.

This application is currently deployed with Docker. There is a Nix derivation in nix/docker-image.nix that builds a minimal container for the application. The Makefile includes a deploy target that builds that derivation and uploads it to the production site. You can run make overriding the DEPLOY_HOST variable to change the server it deploys to.

The application requires a TOML-formatted file containing two secrets labeled steam_api_key and session_private_key_hex. If it's not explicitly named (either as an argument or environment variable), the app will load secrets.toml from the app root.

The application looks for the following environment variables:

Environment Variable	Required
DB_HOST	no
DB_PORT	no
DB_NAME	no
DB_USER	no
DB_PASSWORD	yes
HOST	no
REDIS_HOST	yes
REDIS_PORT	no
REDIS_USER	no
REDIS_PASSWORD	no
SECRETS_TOML	no
SENTRY_DSN	no
WEB_PORT	no
WS_PORT	no

nginx proxy

The server command expects HTTP to be served at the root directory, and the WS port to be served at /ws/. This can be achieved with nginx like this:

server {
    location / {
        proxy_pass http://127.0.0.1:$WEB_PORT/;
        proxy_http_version 1.1;
        proxy_read_timeout 300s;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $remote_addr;
    }

    location /ws/ {
        proxy_pass http://127.0.0.1:$WS_PORT/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $remote_addr;
    }
}

…with $WEB_PORT and $WS_PORT replaced with values the correct ports to connect to the app server.
