Learn the single repository model of the monorepo approach.
What is a monorepo?
A monorepo is a development approach where multiple projects or applications are stored in a single Git repository. For example, a company's web application, mobile application, and shared libraries can exist in the same repository.
company/
├── frontend/
├── backend/
├── mobile/
└── shared/This allows projects to manage shared files and changes through a single repository.
One repository, multiple projects
When using a monorepo, each project has its own directory, but all projects share the same Git history. A single commit can contain changes affecting multiple projects.
workspace/
├── api/
│ └── index.js
├── web/
│ └── app.js
└── packages/
└── utils.jsThis model makes sharing common code and reviewing cross-project changes easier. However, cloning and maintenance costs can increase in large repositories.
Practice Create monorepo directories
Create the frontend, backend, and shared directories for a monorepo. Then list the directories using the find command.
Starter code
# Proje dizinlerini oluştur
# Dizinleri listeleSample solution
mkdir -p frontend backend shared
find . -maxdepth 1 -type d | sortExpected output
. ./backend ./frontend ./shared
