HumbleShare

Self-hosted spare Steam key / gift-link share for a small group of friends. Replaces the Humble Bundle spreadsheet.

Stack: Go (Fiber) + Postgres 16 + SvelteKit 2 (Svelte 5) + Tailwind 4.

Local setup

cp .env.example .env
# set SUPERADMIN_EMAIL and AUTH_JWT_SECRET
docker compose -f docker-compose.dev.yml up --build

Dev compose puts Traefik in front (same host / path split idea as production):

• App: http://humbleshare.localhost
• Games catalog: http://humbleshare.localhost/games
• Health: http://humbleshare.localhost/health
• Login: http://humbleshare.localhost/login
• Request access: http://humbleshare.localhost/request-access
• Traefik dashboard: http://localhost:8081
• Mailpit (caught email): http://localhost:8025

*.localhost resolves to 127.0.0.1 on current browsers / macOS. Traefik routes /api/v1, /health, and /webhooks to the Go API; everything else (including the SvelteKit BFF under /api/...) goes to the web container.

On first boot the API creates a superadmin for SUPERADMIN_EMAIL. If SUPERADMIN_PASSWORD is set (Infisical /api/auth key superadmin_password), the account is created immediately. Otherwise an invite is emailed (Mailpit in dev).

Or run pieces on the host (no Traefik; hit Vite/API ports directly):

docker compose -f docker-compose.dev.yml up -d postgres mailpit
cd api && cp ../.env.example .env
make dev
cd web && npm i && npm run dev

Environment variables

Config precedence: env > CLI > optional TOML > Infisical > defaults.

When Infisical Machine Identity bootstrap env is set, secrets are loaded on startup (API: /api recursively; web: /ui recursively). Failures abort startup. Process env still overrides Infisical for operational tweaks.

Infisical paths (folder → key → env)

Path	Key	Env
/api/db	url	DATABASE_URL
/api/db	ca_cert	PEM; written to a temp file and PGSSLROOTCERT is set if unset
/api/auth	jwt_secret	AUTH_JWT_SECRET
/api/auth	superadmin_email	SUPERADMIN_EMAIL
/api/auth	superadmin_password	SUPERADMIN_PASSWORD
/api/auth/superadmin_password	password	SUPERADMIN_PASSWORD
/api/auth	cookie_secure	COOKIE_SECURE
/api/auth	session_max_age_seconds	SESSION_MAX_AGE_SECONDS
/api/auth	public_web_base_url	PUBLIC_WEB_BASE_URL
/api/mailgun	api_key, domain, from, api_base	MAILGUN_*
/api/auth/google	client_id, client_secret	GOOGLE_OAUTH_*
/api/auth/discord	client_id, client_secret	DISCORD_OAUTH_*
/api/auth/steam	api_key	STEAM_API_KEY
/api/auth/turnstile	site_key, secret_key	TURNSTILE_SITE_KEY / TURNSTILE_SECRET_KEY
/api/r2	account_id, access_key_id, secret_access_key, bucket, public_base_url, user_assets_bucket, user_assets_public_base_url	R2_* (static + user-assets buckets)
/api/steam	claim_rate_limit_per_minute / metadata_cache_ttl_seconds / rate_per_second	claim / Steam knobs
/api/sentry	dsn, environment, release, traces_sample_rate	SENTRY_* (API)
/ui/api	internal_url	API_INTERNAL_URL
/ui/auth	cookie_secure	COOKIE_SECURE
/ui/sentry	dsn, server_dsn, environment, release, traces_sample_rate	PUBLIC_SENTRY_DSN / SENTRY_* (web)

Operational knobs such as HTTP_ADDR and CORS_ORIGINS stay on env/TOML.

Bootstrap + common env

Variable	Service	Description
DATABASE_URL	API	Postgres connection string
AUTH_JWT_SECRET	API	Signs 2FA pending / invite approve / OAuth state JWTs
SUPERADMIN_EMAIL	API	First superadmin email
SUPERADMIN_PASSWORD	API	Optional; creates that account on boot (skips invite)
MAILGUN_API_KEY / MAILGUN_DOMAIN	API	Production email (ignored when SMTP_HOST is set)
SMTP_HOST / SMTP_PORT / SMTP_FROM	API	Local SMTP (Mailpit in docker-compose.dev.yml)
PUBLIC_WEB_BASE_URL	API	Browser origin for invite/OAuth links
API_INTERNAL_URL	Web	Go API base URL for the BFF
SENTRY_DSN	API (+ optional web server)	Sentry DSN; empty disables the SDK
PUBLIC_SENTRY_DSN	Web	Browser Sentry DSN (same project DSN is fine)
SENTRY_ENVIRONMENT / SENTRY_RELEASE	API + Web	Environment and release tags
COOKIE_SECURE	API + Web	true in production HTTPS
SESSION_MAX_AGE_SECONDS	API	Session cookie max-age (default 30d)
R2_ACCOUNT_ID / R2_ACCESS_KEY_ID / R2_SECRET_ACCESS_KEY	API	Shared R2 credentials
R2_BUCKET / R2_PUBLIC_BASE_URL	API	Static assets bucket + public CDN (https://assets.humbleshare.com)
R2_USER_ASSETS_BUCKET / R2_USER_ASSETS_PUBLIC_BASE_URL	API	User uploads (avatars, banners) + public CDN (https://user-assets.humbleshare.com)

Auth

1. Visitors submit Request access with an email.
2. Admins (and SUPERADMIN_EMAIL) get a Mailgun notification; approve in Admin or via the email link.
3. The requester gets an invite email, sets a password, and signs in.
4. Optional: enable TOTP 2FA and link Google / Discord / Steam from Settings.
5. Superadmin can promote other users to admin in the portal.

Sessions use an opaque humbleshare_session cookie (hashed at rest). The SvelteKit BFF proxies /api/* so the browser never talks to Go with secrets in client JS.

Humble session cookie

For Admin → Import:

1. Log into humblebundle.com in a browser.
2. DevTools → Application/Storage → Cookies → copy _simpleauth_sess.
3. Paste into the import form: Humble gift links (gift?key=…) and/or order gamekeys (downloads?key=…). Steam CD keys go in Bulk paste.
4. The cookie is sent only for that request and is never written to the database or logs.

Production

Root docker-compose.yml is the Traefik/Infisical production stack (GHCR images on an external shared-network). Build and push humbleshare-api / humbleshare-web via CI; prefer Infisical for secrets (process env remains a valid override).

Dev Traefik mirrors production router names (humbleshare-api / humbleshare-web) and priorities. Local uses plain HTTP on :80 and PathPrefix(/api/v1) so OAuth callbacks hit Go while the BFF keeps /api/*. Production labels still use the broader PathPrefix(/api) (TLS + Let's Encrypt on the external Traefik).

Design notes

• Claiming is a single conditional UPDATE … WHERE status = 'available' (see ClaimOldestAvailable). Concurrent losers get 409.
• Public game list never includes code_value. The key appears only after a successful claim (and on admin inventory).
• Game identity comes from Humble titles or manual entry; Steam metadata is resolved from the title, never from the opaque key.
• Claims store claimed_by_user_id plus a denormalized display name.
