Starter

A catalog of project templates organized by two independent dimensions: system (the application) and system-test (the test harness). Each template is self-contained and copy-paste-ready.

System Templates

Pick based on your architecture and language:

Monolith

Language	Directory	Framework	Port	SonarCloud
Java	system/monolith/java/	Spring Boot + Thymeleaf (SSR)	8080	starter-monolith-java
.NET	system/monolith/dotnet/	ASP.NET Core Razor Pages	8080	starter-monolith-dotnet
TypeScript	system/monolith/typescript/	Next.js (SSR)	3000	starter-monolith-typescript

Multitier

Frontend

Language	Directory	Framework	Port	SonarCloud
TypeScript	system/multitier/frontend-react/	React + Nginx	8080	starter-multitier-frontend-react

Backend

Language	Directory	Framework	Port	SonarCloud
Java	system/multitier/backend-java/	Spring Boot API	8081	starter-multitier-backend-java
.NET	system/multitier/backend-dotnet/	ASP.NET Core API	8081	starter-multitier-backend-dotnet
TypeScript	system/multitier/backend-typescript/	NestJS API	8081	starter-multitier-backend-typescript

System-Test Templates

Pick based on your preferred test language (independent of system language):

Language	Directory	Framework
Java	system-test/java/	JUnit 5 + Playwright
.NET	system-test/dotnet/	xUnit + Playwright
TypeScript	system-test/typescript/	Jest + Playwright

Each system-test includes docker-compose files for both architectures in local and pipeline variants (e.g. docker-compose.local.monolith.real.yml, docker-compose.pipeline.multitier.stub.yml). Remove the files for the architecture you don't need.

CI/CD Pipelines

The .github/workflows/ directory contains runnable pipelines for all 6 matched-language combinations (system + system-test):

Monolith Java

Monolith .NET

Monolith TypeScript

Multitier Java

Multitier .NET

Multitier TypeScript

• Commit stages trigger automatically on push via path filters
• Acceptance/QA/Prod stages are workflow_dispatch (manual trigger)

Verification

verify-all — runs the full pipeline on the starter repo's own templates:
