🎉 Shalo - Optimize Git Size for Nx Monorepo

#### Inspired by tiktok sparo for RushJS

A typical Nx Monorepo folder structure can be complex, especially when the number of applications and their dependencies on shared libraries grows. To address this, Shalo leverages Git's shallow clone and sparse checkout functionalities to streamline operations.

!Monorepo Structure

Educating hundreds of engineers working in a monorepo about which shared packages and components their apps need can be challenging. Shalo is a CLI tool built with Node.js designed to simplify this process.

🚀 Install Shalo on Your Machine

- You can install Shalo globally using the following command:

``
npm install -g shalo
`

> ## ⚠️ Note:
> This can be used in your CI Pipelines as well

🛠️ Clone Your Repository

- To clone your repository, run:
`
shalo clone
`

- Alternatively, you can use:
`
npx shalo clone
`

📦 Install Dependencies in Your Repository

- After cloning, navigate into your repository and install the dependencies:
`
npm install


or


yarn install
`

📥 Checkout Required Apps in the Nx Monorepo

- To checkout only the apps you need, use the following command. Shalo computes the dependencies within Nx and checks out all required dependent apps in the monorepo:
`
shalo checkout -a
`

❌ Exclude Dependent Apps
- If necessary, you can exclude specific dependent apps. However, be cautious with this option, as it may break Nx builds or other Nx commands:
`
shalo checkout -a -e
`

📂 Checkout Only Folders

- If you need to checkout only specific folders without computing dependencies, you can use:
`
shalo checkout -f
`

> ## ⚠️ Note:
> After checking out the required apps, ensure that you use the shalo add command when adding more apps or folders.
> Running shalo checkout again will overwrite the apps or folders you’ve already checked out.




➕ Adding Folders to Sparse Mode


- To add additional folders (like mocks, tools, etc.) to your sparse mode monorepo, run:
`
shalo add -f
`

➕ Add Apps and Dependencies

- You can also add an Nx app along with its dependencies to the sparse repo using the following command:
`
shalo add -a
`

❌ Remove apps / folders

- To remove any app with dependencies or just the folder from sparse-checkout list, use the following command:
`
shalo remove -f
shalo remove -a
`

🔄 Disable Sparse Checkout

- To exit sparse checkout mode or to disable it and revert to using the Git CLI, execute:
`
shalo clean
`
