Melos

What Melos is

Melos is a command-line tool for managing Dart and Flutter projects, especially workspaces containing multiple packages. It links and installs local packages, synchronizes shared dependencies during bootstrap, and can run commands across packages at once. Filters let teams target packages by scope, category, dependencies, or whether packages changed. Melos also lists packages and dependencies, and automates versioning and changelog generation; it can publish packages to pub.dev. It supports CI/CD automation and provides a GitHub Action. Single-package projects can use it for versioning, publishing, and changelog generation too. IntelliJ integration can create project modules and run configurations, while the VS Code extension offers configuration validation, autocompletion, tasks, and package graphs. Melos is free and installs globally with `dart pub global activate melos`. Version 8.x.x requires Dart SDK 3.9.0 or newer. Publishing requires permission for every package and a machine authenticated with Pub; dry-run is enabled by default.
