The Definitive Deep Dive into the .git Folder

on YouTube ↗01h 00m

" summary

Walks through every file in .git and proves how commits, trees and blobs are stored by creating a repo, adding files and inspecting zlib objects with a custom unzipper Node script, then builds and demoes a browser visualizer Git Explorer (Node/TypeScript, npm start) that color-codes commit/tree/blob nodes. Shows that one simple commit produces three objects from one commit, staging creates blob objects before commit, identical file contents dedupe to one blob, and dangling/amended commits still remain in objects.
