Introducing Service Weaver: A Framework for Writing Distributed Applications

Service Weaver is an open-source framework designed for building and deploying distributed applications. The framework enables developers to write their applications as modular monoliths and deploy them as a set of microservices.

The Service Weaver framework aims to improve distributed application development velocity and performance by decoupling the process of writing the application from runtime considerations such as how the application is split into microservices, what data serialization formats are used, and how services are discovered.

The core idea of Service Weaver is its modular monolith model, where developers write a single binary using only language-native data structures and method calls. They organize their binary as a set of modules, called components, which are native types in the programming language. Service Weaver allows developers to run their applications anywhere, on their local desktop environment or on their local rack of machines or in the cloud, without any changes to their application code.
