Features

• Monorepo Managers - Provides a comprehensive system for coordinating multiple related JavaScript packages within a single repository.
• Monorepo Workflow Orchestration - Manages the build, test, and publishing processes for multiple separate packages residing within a single shared repository.
• Build Orchestrators - Acts as a build orchestrator that manages parallel execution and sequencing for multi-package projects.
• Dependency Installers - Installs and links dependencies across all project packages while hoisting external libraries.
• Local Package Linking - Creates symlinks between internal packages to enable local development and testing without requiring an external registry.
• Task Dependency Linkers - Allows users to specify the execution sequence for tasks to ensure dependent packages are built before successors.
• Topological Task Sequencing - Determines execution order by analyzing package dependencies to ensure a package builds before its dependents.
• Workspace Managers - Manages local package linking and shared dependencies across a multi-package workspace.
• Parallel Execution - Runs scripts across multiple packages using parallel execution and caching to avoid repeating work.
• Symlink-Based Dependency Management - Connects internal packages using filesystem symbolic links to allow local development without publishing to a registry.
• Automated Release Management - Updates version numbers across packages using automated changelogs and commit history to generate project releases.
• Dependency Hoisting - Reduces disk usage and avoids duplicate installations by hoisting shared external libraries to a single root directory.
• Commit-Based Versioning Engines - Calculates the next semantic version number by parsing standardized commit messages from version control history.
• Build Result Caching - Implements content-hash caching to skip redundant executions of build, test, and lint tasks.
• Monorepo Orchestration - Implements dependency-aware orchestration of build, test, and lint tasks across the entire workspace.
• Parallel Task Executors - Runs independent scripts across multiple packages simultaneously while respecting dependency constraints.
• Task Execution Caches - Utilizes content-hash caching to skip redundant task executions when input files remain unchanged.
• Package Publishing - Provides mechanisms to publish multiple packages to a registry using topological ordering and trusted authentication.
• Build Configuration - Allows for the definition of standard input and target defaults to unify how packages are compiled, linted, and tested.
• Execution Scope Filtering - Restricts command execution to specific packages using directory patterns or by identifying changed files.
• Task Execution Filtering - Restricts command execution to specific subsets of the workspace using glob patterns or git-based change detection.
• Build Tools and Bundlers - Build system for managing multi-package repositories.
• Build Tools and Tooling - Build system for managing multi-package repositories.
• Monorepo Management - Tool for managing multi-package projects.
• Project Management Tools - Tool for managing multi-package repositories with git and npm.
