The tinystruct framework

A simple framework for Java development. Simple thinking, Better design, Easy to be used with better performance!

Prerequisites

• Java Development Kit (JDK) 17 or higher
• Maven (for dependency management)
• A text editor or IDE (IntelliJ IDEA, Eclipse, VS Code, etc.)

Getting Started with tinystruct archetype

You can follow this archetype to create a tinystruct-based project quickly: https://github.com/tinystruct/tinystruct-archetype

Installation and Getting Started Manually

• Add the dependency into your pom.xml.

<dependency>
  <groupId>org.tinystruct</groupId>
  <artifactId>tinystruct</artifactId>
  <version>1.7.35</version>
</dependency>

To use the framework as a standalone command-line tool, build the optional jar that bundles all dependencies (about 50 MB, not part of the release):

./mvnw package -Pstandalone        # Windows: mvnw.cmd package -Pstandalone
java -jar target/tinystruct-1.7.35-jar-with-dependencies.jar --help

• Extend the AbstractApplication in Java:

package tinystruct.examples;


import org.tinystruct.AbstractApplication;
import org.tinystruct.ApplicationException;
import org.tinystruct.system.annotation.Action;

public class example extends AbstractApplication {

    @Override
    public void init() {
        // TODO Auto-generated method stub
    }

    @Override
    public String version() {
        return "1.0";
    }

    @Action("praise")
    public String praise() {
        return "Praise the Lord!";
    }

    @Action("say")
    public String say() throws ApplicationException {
        if (null != getContext().getAttribute("--words"))
            return getContext().getAttribute("--words").toString();

        throw new ApplicationException("Could not find the parameter <i>words</i>.");
    }

    @Action("say")
    public String say(String words) {
        return words;
    }

    @Action(value = "hello", mode = Mode.HTTP_GET)
    public String helloGet() {
        return "GET";
    }

    @Action(value = "hello", mode = Mode.HTTP_POST)
    public String helloPost() {
        return "POST";
    }

}

Handling over 86,000 requests per second with low average latency (~17.44ms), indicating the endpoint is highly efficient under heavy load. this shows the raw power and efficiency of the tinystruct framework. But it's not just about the performance numbers. It's about the philosophy behind it.

What makes tinystruct framework modern?

1. No main() method required Applications can be started directly using CLI commands like bin/dispatcher, with no boilerplate code needed. This removes unnecessary ceremony from the development lifecycle.

2. Unified design for CLI and Web Unlike Spring Boot which is primarily web-centric, tinystruct treats CLI and Web as equal citizens. This makes it perfect for AI tasks, script automation, and hybrid applications — all from the same codebase.

3. Built-in lightweight HTTP server Whether it’s Netty or Tomcat, tinystruct integrates the server lifecycle inside the framework. There's no need for separate containers or complicated configuration files. Just import what you need and run.

4. Minimal configuration philosophy Configuration is minimized to the essentials. You don't need to wire up hundreds of beans, and there's no excessive XML or YAML involved. This improves developer productivity and reduces bugs.

5. Annotation-based routing The framework provides a clean and intuitive routing mechanism using @Action, eliminating the need for overly complex controller hierarchies.

6. Performance-first architecture There’s almost zero overhead. No reflection-based bean scanning, no auto-wiring maze, no unnecessary interceptors unless explicitly enabled. This translates into faster response times and smaller memory footprint.

7. Developer empowerment without complexity With tinystruct, developers are free to focus on real business logic rather than fighting with framework mechanics. It's designed to be transparent, predictable, and extensible — all without sacrificing control or performance.
