Yarn Workspaces is a feature of the Yarn package manager that allows you to manage multiple packages within a single, centralized codebase. This is particularly useful for monorepo setups, where multiple packages (such as libraries or applications) are maintained in a single repository. Yarn Workspaces simplifies package management, dependencies, and overall project organization.

Setting Up Yarn Workspaces

Initialize Yarn Workspaces

• Create a new project or navigate to an existing one and run yarn init -y to create a package.json file. Add "private": true to the package.json file to signify that the project is not intended for publication.

Configure Yarn Workspaces

• Create a packages directory at the root of your project.
• Move your individual packages (subprojects) into the packages directory.

Update package.json

• In the root package.json, add the following configuration

Benefits of Yarn Workspaces:

Simplified Dependency Management:

• Manage dependencies for all packages in a centralized manner, preventing version conflicts.

Efficient Local Development:

• Changes in one package are immediately reflected in other dependent packages, streamlining local development.

Streamlined CI/CD:

• CI/CD processes are more efficient, as changes in one package can trigger necessary workflows for dependent packages.

Encourages Code Reusability:

• Promotes the creation of reusable components or libraries, easily shared among different parts of the project.

Improved Project Structure:

• Organize your project logically, enhancing maintainability and scalability.
