Rush Stack is a comprehensive monorepo toolchain designed for large-scale TypeScript projects. It provides a suite of integrated tools to streamline development, build orchestration, API documentation generation, and dependency management, targeting developers working with complex JavaScript/TypeScript monorepos.

How It Works

Rush Stack is built around a core set of interconnected tools. Rush acts as the build orchestrator, managing dependencies and executing build tasks across monorepo packages. Heft is the recommended build tool, offering a plugin-based architecture for tasks like compilation, testing, and linting, with specialized plugins for various frameworks and environments. API Extractor and API Documenter automate the generation of API definitions and documentation from TSDoc comments, ensuring API consistency and discoverability.

Quick Start & Requirements

• Installation: Typically managed via npm or yarn within a monorepo. Core tools like Rush can be installed globally or locally.
• Prerequisites: Node.js, npm/yarn. Specific projects may require TypeScript, Jest, Webpack, or other build-time dependencies.
• Documentation: Comprehensive documentation is available at rushstack.io.

Highlighted Details

• Monorepo Management: Rush provides robust support for managing dependencies, linking packages, and executing commands across a large monorepo.
• Extensible Build System: Heft's plugin architecture allows for deep customization of the build process, supporting various JavaScript/TypeScript workflows.
• API Management: Tools like API Extractor and API Documenter enforce API contracts and automate documentation generation, crucial for large libraries.
• Ecosystem Integration: Includes plugins for popular tools like Webpack, Jest, ESLint, and various cloud build cache providers.
