Summary - Monorepo

Combine monorepo tools to set up large repository management.

Combine monorepo management

A monorepo brings multiple projects together in one Git repository. In large repositories, you can use sparse-checkout to work with only the required directories and include other repositories using subtree or submodule.

git sparse-checkout init --cone
git sparse-checkout set frontend shared
git subtree add --prefix=vendor/tool \
  https://example.com/tool.git main

These tools address different needs: sparse-checkout limits the working area, while subtree and submodule include external repositories in the project.

Exercise Use monorepo tools together

Initialize cone mode in a monorepo and select only the apps/web and packages/shared directories. Then add the main branch of https://example.com/utils.git as a subtree in the vendor/utils directory. Print an information message at the end.

Show example solution

git sparse-checkout init --cone
git sparse-checkout set apps/web packages/shared
git subtree add --prefix=vendor/utils https://example.com/utils.git main
echo 'Monorepo yapılandırması tamamlandı'

Test yourself

You want to work with selected project directories in a monorepo while linking another library as an independent repository. Which two tools are suitable together?
- Git bisect and Git blame
- Sparse-checkout and submodule
- Git worktree and Git stash
- Subtree and Git merge
Show answer

Sparse-checkout and submodule — Sparse-checkout checks out selected directories into the working area. A submodule links another repository to the main project as an independent repository reference.

Select the monorepo working area

git sparse-checkout init --cone
git sparse-checkout ____ frontend shared

Show answer

git sparse-checkout init --cone
git sparse-checkout set frontend shared
