Implemented Git Functionality Using JavaScript

This project is a custom implementation of Git functionality, providing a set of core Git operations using Node.js. It enables performing essential Git operations such as initializing a Git repository, managing Git objects (commit, tree, blob), staging and committing files, and cloning remote repositories directly from the command line.

Features

• Git Directory Initialization (init): Creates a basic .git directory structure with necessary subdirectories and a default HEAD file pointing to the main branch.

• Cat File (cat-file): Retrieve information about objects (like commits) stored in the Git repository using their SHA hash.

• Hash Object (hash-object): Hash files and store them as Git objects.

• List Tree (ls-tree): List the contents of a commit or tree object, showing files and directories.

• Write Tree (write-tree): Write the current state of the staged files to a new tree object.

• Commit Tree (commit-tree): Create a new commit object from a tree object, parent commit SHA, and a commit message.

• Clone Repository (clone): Clone a repository from a remote URL to a local directory.

Usage

After installation, you can use the various Git functionalities by running commands in your terminal. Here are some examples:

Usage

After installation, you can use the various Git functionalities by running commands in your terminal. Here are some examples:

• Initialize a Git Repository:

  gitjs init

• Hash a File:

  gitjs hash-object <file-path>

• Clone a Remote Repository:

  gitjs clone <repository-url> <directory>

• Commit a Tree:

  gitjs commit-tree <tree_sha> -p <commit_sha> -m "<message>"

• Write a Tree:

  gitjs write-tree <sha>

• List Tree with --name-only:

  gitjs ls-tree --name-only <sha>

• Hash a File and Store It:

  gitjs hash-object -w <filepath>

• View Git Object Information:

  gitjs cat-file -p <commitSHA>
