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
• UX.md: frontend UX and interaction design specification (pre-implementation baseline)

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:

   pwsh ./scripts/ci-local.ps1
   

2. Start the backend:

   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:

  dotnet test RpgRoller.Tests/RpgRoller.Tests.csproj --collect:"XPlat Code Coverage" --settings RpgRoller.Tests/coverlet.runsettings
  

• Coverage gate:

  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
