GitGo is a minimal Git implementation built from scratch using Go. The project focuses on understanding Git’s core functionality by implementing its fundamental features: blob storage, tree structures, commits, and basic branching.

While it doesn’t aim to replace Git, it provides a deep dive into how version control systems work under the hood. The implementation includes content-addressable storage, binary file handling, and tree-based directory management. This project served as an excellent learning experience for understanding Git internals.

While building GitGo, I learned about:

• Content-addressable storage systems
• Binary file formats and serialization
• Tree data structures for directory management
• SHA-1 based content hashing
• File system operations in Go
• Git’s internal object model (blobs, trees, commits)

The project was a great way to demystify Git’s inner workings and gain practical experience with low-level file system operations and binary data handling in Go.
