Backend

PostgreSQL

The API targets PostgreSQL through EF Core 8 and Npgsql.EntityFrameworkCore.PostgreSQL.

Local development is aligned with ../docker-compose.dev.yml and appsettings.Development.json:

Host=localhost;Port=5433;Database=vtuber_star_awards_dev;Username=vtsa_dev;Password=change-me-local-only

For production or shared deployments, keep checked-in appsettings empty and provide your own value through:

VTSA_POSTGRES
ConnectionStrings__Postgres

The API reads its connection string from:

• environment variable VTSA_POSTGRES
• environment variable ConnectionStrings__Postgres

Presentation/demo data is controlled separately:

VTSA_SEED_MODE=demo

• demo, presentation or sample: seed local presentation data.
• none, off, disabled or an unset value in Production: do not seed presentation data.
• Backend/appsettings.Development.json defaults to demo; Backend/appsettings.json defaults to none.

If Docker is available locally, start a dev database from the repository root with:

docker compose -f docker-compose.dev.yml up -d

Commands

Restore and build:

dotnet restore
dotnet build

Create a migration:

dotnet ef migrations add InitialCreate

Generate a SQL migration script:

dotnet ef migrations script 0 20260617060000_InitialCreate --output Migrations/InitialCreate.sql

Apply migrations once PostgreSQL is running:

dotnet ef database update

Fallback bootstrap if dotnet ef is not usable in the current environment:

psql "$VTSA_POSTGRES" -f Migrations/InitialCreate.manual.sql

Run the API:

ASPNETCORE_ENVIRONMENT=Development dotnet run --urls http://127.0.0.1:5084

Check the API and database wiring:

curl http://127.0.0.1:5084/api/health
curl http://127.0.0.1:5084/api/health/database

Development auth/session:

curl -X POST http://localhost:5084/api/auth/dev-login \
  -H "Content-Type: application/json" \
  -d '{"twitchUserId":"jayuhime_admin","displayName":"Jayuhime Admin","role":"admin"}'

Demo admin login for public presentations:

VTSA_DEMO_LOGIN_ENABLED=true
VTSA_DEMO_ADMIN_LOGIN=jayuhime_admin
VTSA_DEMO_ADMIN_EMAIL=admin@example.local
VTSA_DEMO_ADMIN_PASSWORD=<set-secure-demo-password>
VTSA_DEMO_ADMIN_TWITCH_ID=jayuhime_admin
VTSA_DEMO_ADMIN_DISPLAY_NAME=Jayuhime Admin

The frontend route is /login. VTSA_DEMO_ADMIN_LOGIN may be a username or an email-style identifier; the backend also accepts the configured email, Twitch ID, and display name for admin flexibility. Disable the demo login for release with VTSA_DEMO_LOGIN_ENABLED=false.

Frontend app-wide demo gate:

VITE_DEMO_GATE_ENABLED=true

• true: if /api/public/site-status is unavailable, the Vue app still starts at /login until a session exists.
• unset or false: if /api/public/site-status is unavailable, public pages such as / remain visible without the initial demo login.

When /api/public/site-status is reachable, the backend demoLoginEnabled flag is authoritative.
