REST API Generator

Rrezart Prebreza — Tue, 07 Apr 2026 13:15:56 +0000

After days of work, REST API Generator is now live on a public test server.

👉 https://rest-api-generator-ag0z.onrender.com

No install. No account. Open it in your browser, write a plain-English description of your API, and get a complete Spring Boot 3 project in 30 seconds.

Example:
"Create an API for Product with name, price (decimal, min 0), belongs to Category"

What gets generated:
→ Entity (JPA, auditing, relationships)
→ DTO (Bean Validation from your prompt)
→ Service (@Transactional, pagination, filter)
→ Controller (proper HTTP status codes, @valid)
→ Repository (JpaSpecificationExecutor)
→ MapStruct Mapper
→ GlobalExceptionHandler (404, 400, 500)
→ Flyway migration SQL
→ Dockerfile + docker-compose.yml
→ Unit tests + MockMvc integration tests

I am actively improving it and I would love your feedback.

REST API Generator with Spring Boot and Spring AI

Rrezart Prebreza — Fri, 27 Feb 2026 09:33:59 +0000

Hey everyone, I started building a REST API Generator with Spring Boot and Spring AI that turns prompts into real backend projects.
Instead of starting from scratch, you can already generate:
• Controllers
• Services
• Repositories
• DTOs
• Validation
• Tests
• OpenAPI docs
• Docker setup
Still improving it, but it’s already useful for reducing boilerplate and moving faster.
Check it out on GitHub:

If you have ideas or feedback, I’d love to hear them.

JAI Router - lightweight Spring Boot routing starter (open for contributors)

Rrezart Prebreza — Tue, 02 Dec 2025 13:25:07 +0000

JAI Router is a minimal Spring Boot starter that centralizes dynamic route registration and exposes a small admin API for runtime routing. The project is ready for contributors — see CONTRIBUTING.md and issues labeled good first issue and help wanted.

Problem

Dynamic route registration is often scattered across services and hard to test.
Existing solutions introduce heavy dependencies or tightly couple to framework internals.

What JAI Router does

Provides a small, testable API to register and manage routes at runtime.
Integrates as a Spring Boot starter with minimal dependencies.
Keeps route storage and dispatching modular and easy to mock in tests.

Key features

Runtime route registration and removal.
Pluggable route matching and handler resolution.
Small API surface suitable for microservices and integration tests .

Quickstart

Clone the repo: git clone hhttps://github.com/JAI-create-spec/JAI-Router/tree/develop
Run locally: ./gradlew bootRun (Java 17)
See README.md for quick-start snippets and example endpoints.

Example usage
Register a route via the admin API and validate it with an integration test. See README.md for concrete request and response examples.

How to contribute
Read CONTRIBUTING.md for setup, tests, and branch conventions.

Pick a starter issue labeled good first issue or help wanted.

Open small PRs with tests; maintainers aim to review quickly.
