JavaScript and TypeScript Monorepos

• Understanding Monorepos: Gain a deep understanding of what monorepos are and how they can simplify project management by housing multiple related packages in a single repository.
• Tooling with Yarn, Lerna, and Volta: Learn how to use tools like Yarn Workspaces for dependency management, Lerna for running scripts and managing versioning, and Volta for handling specific Node.js and Yarn versions across different projects.
• Configuring TypeScript Projects: Set up composite TypeScript projects and manage build outputs effectively, ensuring consistent configurations across multiple packages.
• Testing and Linting: Implement consistent testing with Jest and Babel across packages and centralize linting rules with ESLint, maintaining code quality throughout the monorepo.
• Release Management with Conventional Commits: Use tools like Husky and commitlint to enforce commit message conventions, and automate changelog generation and versioning with Lerna.
• Internal Package Management: Learn how to manage internal dependencies and publish them using tools like Verdaccio, ensuring smooth dependency tracking within the monorepo.
• API Documentation: Automate API documentation generation with tools like API Extractor and API Documenter, making it easier for teams to maintain and understand large codebases.

This course provides hands-on experience with managing JavaScript and TypeScript monorepos. You’ll learn how to set up and maintain a monorepo using best-in-class tools like Yarn Workspaces, Lerna, and Volta. The course also covers advanced topics like testing with Jest, handling internal dependencies, and automating API documentation, all while maintaining a clean and scalable codebase.
