Pragmatica Lite

A lightweight Java framework built on modern functional programming principles for robust application development.

Project Overview

Pragmatica Lite is a Java framework that provides robust error handling, functional programming constructs, and distributed systems capabilities. Built on Java 24, it leverages modern language features to create reliable and maintainable applications.

Modules

The project is organized into the following modules:

Core

Contains the essential functional programming abstractions including:

• Result types for safe error handling
• Option types for null-safety
• Promise implementations for asynchronous operations
• Functional interfaces and utilities

Common

Provides common utilities and shared components used across the framework.

Features

• Functional style - no NPE, no exceptions, type safety, etc.
• Option/Result/Promise monads with consistent and compatible APIs.
• Simple and convenient to use Promise-based asynchronous API.

Core Library

The Pragmatica Lite Core contains implementation of basic monads: Option<T>, Result<T> and Promise<T>. See module README.md for more information.

Cluster

Implementation of distributed clustering layer, based on modern leaderless Rabia consensus algorithm. See module README.md for more details.

Net-Core

Easy to use Netty-based networking layer.

Examples

Sample applications demonstrating framework usage.

Getting Started

As for now project packages are hosted at GitHub Packages. To use them use the following Maven repository:

<repositories>
    <repository>
        <id>github</id>
        <url>https://maven.pkg.github.com/siy/pragmatica-lite</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
        <releases>
            <enabled>true</enabled>
        </releases>
    </repository>
</repositories>

Then add a necessary dependency:

<dependency>
    <groupId>org.pragmatica-lite</groupId>
    <artifactId>[MODULE_NAME]</artifactId>
    <version>0.7.6</version>
</dependency>

Where [MODULE_NAME] is one of the following:

• core
• cluster
• net-core
• common
