Understanding Git Monorepo

Using a Monorepo

Git monorepo manages multiple projects in one repository.

What is a Git Monorepo?

A Git monorepo is a version control strategy where multiple projects are stored within a single repository. This approach contrasts with using multiple, separate repositories for each project. Monorepos can simplify dependency management, provide a single source of truth for the entire codebase, and facilitate easier cross-project refactoring.

Benefits of a Git Monorepo

Unified Versioning: All projects share the same version history, making it easier to trace changes across different projects.
Simplified Dependency Management: Directly manage dependencies between projects without needing external package management systems.
Consistent CI/CD: Implement a uniform continuous integration and delivery process across all projects.

Setting Up a Git Monorepo

To set up a monorepo, you can create a new repository or convert an existing one to include multiple projects. Here’s a basic example on how to organize a monorepo structure:

Working with a Git Monorepo

When working with a monorepo, you can utilize Git commands to manage changes across projects. Here’s an example of how you might commit changes that affect multiple projects:

Best Practices for Git Monorepos

Modularize Code: Keep code modular to ensure that changes in one part of the monorepo don't unintentionally affect other areas.
Use CI Tools: Leverage CI/CD tools to manage builds and tests efficiently across the monorepo.
Regular Refactoring: Periodically refactor and clean code to maintain the health of the monorepo.
