Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure.

Simplifying Dart Mono-repo Management for Efficient Code Sharing and Collaboration

Simplifying Dart Mono-repo Management for Efficient Code Sharing and Collaboration

As the popularity of Dart projects with multiple packages (mono-repos) continues to rise, managing code bases in such environments presents unique challenges. Traditional methods of making changes and testing across repositories can become complex and time-consuming. However, Melos, a powerful command-line interface (CLI) tool, solves these problems. Developed for Dart projects, Melos enables seamless management of multiple packages within a single repository while maintaining their independence. It simplifies versioning, changelog generation, publishing, package linking, and execution of simultaneous commands across packages. In this talk, we will explore the features and benefits of Melos, highlighting its role in enhancing code sharing, collaboration, and automating complex tasks in CI/CD environments. Join us to learn how Melos can transform your Dart mono-repo management and streamline your development workflow.
