Introduction

Mélodium is a language and runtime for building robust stream-processing, event-driven, and distributed software. Unlike conventional languages that process data step by step, Mélodium describes programs as graphs of treatments connected by data flows, where execution is driven by data availability rather than instruction order.

This book covers the purpose of Mélodium, its core concepts, and how to program and work with it. For the full API reference, see the Mélodium Standard Reference. Source code is available on the repository. The Official Project Website has news and release information.

Mélodium and this book are a work in progress, aiming to evolve and grow significantly with time. The information presented here may not always be up to date with the current state of the project. All this work is done with passion and any feedback is welcome.
