What is Monorepo?

A Monorepo (short for “monolithic repository”) is a single version-controlled repository that stores code for multiple projects, services, or components within an organization.

Unlike having separate repositories for each project (polyrepo approach), a monorepo centralizes all codebases in one place.

Key Features of Monorepos

Centralized Codebase

All projects live in a single repository, making it easier to manage dependencies and ensure consistency.

Shared Code

Code can be shared and reused across projects without the need for external package management.

Unified CI/CD

A single pipeline can test and build multiple projects, reducing configuration overhead.

Advantages of Monorepos

Code Sharing and Collaboration

Developers can share utilities, libraries, or components across projects without duplicating efforts.

Changes in shared code are instantly reflected across all projects.

Simplified Dependency Management

Tools like Yarn Workspaces or Nx handle dependencies effectively, avoiding version mismatches.

Improved Visibility
