Polyglot REST-API

A simple REST API implemented across multiple technology stacks for comparison and learning.

ASP.NET Core Minimal – UserManagement

The aspnet-core-minimal/UserManagement project is a minimalist REST API for user management, built with ASP.NET Core 9.0. It provides basic endpoints for creating, retrieving, updating, and deleting users (CRUD). The API uses an in-memory repository and serves as a quick-start template or reference implementation.

Features:

• Minimal API approach with modern .NET features
• OpenAPI/Swagger integration (development only)
• Example user endpoints:
  • GET /api/users – Retrieve all users
  • POST /api/users – Create a new user
  • PUT /api/users – Update a user
  • DELETE /api/users/{userId} – Delete a user
• Dockerfile included for containerized deployment

How to run locally:

cd aspnet-core-minimal/src/UserManagement.Api
dotnet run

The API will be available at http://localhost:5100 by default.

Note:
User data is stored in memory and will be lost when the application restarts.

Spring Boot – UserManagement

The spring-boot project provides a REST API for user management, implemented with Java and Spring Boot. It offers endpoints for creating, retrieving, updating, and deleting users (CRUD operations). The application uses a simple in-memory HashMap to store user data for demonstration and development purposes.

Features:

• RESTful API using Spring Boot
• In-memory storage with Java HashMap for easy setup
• Example user endpoints:
  • GET /api/users – Retrieve all users
  • POST /api/users – Create a new user
  • PUT /api/users/{id} – Update a user
  • DELETE /api/users/{id} – Delete a user
• Dockerfile included for containerized deployment

How to run locally:

cd spring-boot
./mvnw spring-boot:run

The API will be available at http://localhost:8080 by default.

Note:
User data is stored in an in-memory HashMap and will be lost when the application restarts.

Delphi (Horse) – UserManagement

The delphi-horse project implements a REST API for user management using Delphi and the Horse web framework. Horse was installed via the boss package manager for Delphi. The API provides endpoints for creating, retrieving, updating, and deleting users (CRUD), with user data stored in memory.

Features:

• RESTful API using Delphi and Horse
• Horse framework installed via boss install horse
• In-memory storage for user data

Available endpoints:

• GET /api/users – Retrieve all users
• GET /api/users/:id – Retrieve a user by ID
• POST /api/users – Create a new user
• PUT /api/users/:id – Update a user
• DELETE /api/users/:id – Delete a user
• GET /api/info – Get API info
• GET /api/health – Health check endpoint

How to run locally:

1. Open the Delphi project in the delphi-horse folder.
2. Build and run the application.

The API will be available at http://localhost:9000 by default.

Example:

curl http://localhost:9000/api/users

Note:
User data is stored in memory and will be lost when the application restarts.
