# RpgRoller

Fresh full-stack starter scaffold:

- `RpgRoller/`: ASP.NET Core backend + static frontend output (`wwwroot`)
- `RpgRoller/frontend/`: TypeScript frontend source
- `RpgRoller.Tests/`: xUnit integration-heavy test project
- `RpgRoller.sln`: solution used by local CI script

Test layout:

- `RpgRoller.Tests/Api/`: API integration tests grouped by feature concern
- `RpgRoller.Tests/Services/`: service-level tests grouped by domain concern
- `RpgRoller.Tests/Support/`: shared test harnesses/builders/helpers

## Code Organization

Backend:

- `RpgRoller/Program.cs`: thin app bootstrap only
- `RpgRoller/Hosting/`: service registration + startup initialization
- `RpgRoller/Api/`: endpoint mapping modules and auth/session filter helpers
- `RpgRoller/Services/`: game workflows with explicit method parameters (no API DTO dependencies)

Frontend:

- `RpgRoller/frontend/app.ts`: orchestration entrypoint
- `RpgRoller/frontend/app/`: split modules (`dom`, `state`, `loaders`, `render`, `events`, `actions`)
- `RpgRoller/frontend/generated/`: generated API client source
- `RpgRoller/wwwroot/`: compiled browser assets

Backend state persistence:

- EF Core with SQLite (`Microsoft.EntityFrameworkCore.Sqlite`)
- Development DB: `RpgRoller/App_Data/rpgroller.development.db`
- Default DB: `RpgRoller/App_Data/rpgroller.db`
- Database schema is created automatically on startup (`EnsureCreated`)
- Runtime state is loaded once at startup into memory and written back to SQLite on successful state changes

## Prerequisites

- .NET SDK 10.0+
- Node.js 22+ and npm
- PowerShell 7+

## Local Development

1. Run the local CI parity script:
   ```powershell
   pwsh ./scripts/ci-local.ps1
   ```
2. Start the backend:
   ```powershell
   dotnet run --project RpgRoller/RpgRoller.csproj
   ```
3. Open `http://localhost:5000` (or the port shown in the console).

To use a custom SQLite database path, set `ConnectionStrings__RpgRoller`.

## Frontend Tooling

- OpenAPI contract: `openapi/RpgRoller.json`
- TypeScript build output config: `tsconfig.frontend.json`
- API client generation + frontend compile: `npm run generate:api-client`
- Frontend lint checks: `npm run lint`
- Frontend format checks: `npm run format:check`

## Test and Coverage

- Tests:
  ```powershell
  dotnet test RpgRoller.Tests/RpgRoller.Tests.csproj --collect:"XPlat Code Coverage" --settings RpgRoller.Tests/coverlet.runsettings
  ```
- Coverage gate:
  ```powershell
  pwsh ./scripts/check-coverage.ps1 -MinLineRate 0.90 -MinBranchRate 0.70
  ```
- Coverage collector scope:
  - `RpgRoller.Tests/coverlet.runsettings` now measures the full backend assembly (`RpgRoller`), not only service namespace files.

## Implemented Backend Scope

- Auth: register, login, logout, current user context
- Session cookie: `HttpOnly`, `SameSite=Strict`, `Secure` when served over HTTPS
- Rulesets: d6 and dnd5e validation rules
- Campaigns: create/list/read
- Characters: create/update/activate/current-campaign list
- Skills: create/update with ruleset-aware dice expression validation
- Rolls: public/private skill rolls with append-only campaign log
- State stream: SSE endpoint for campaign version updates

## Implemented Frontend Scope

- TypeScript-driven UI for:
  - registration, login, logout
  - campaign creation and selection
  - character creation and activation
  - skill creation and editing
  - public/private rolling and campaign log viewing
- SSE-backed live refresh for selected campaign state/log
