This project is a simple Node.js script that generates artificial commit history to paint the GitHub contribution graph — useful for creating pixel art or writing text (like your name!) using the green squares on your GitHub profile.
This script makes 100 commits for every day of the year 2006, using backdated Git commits. The commits are pushed to a connected Git repository and visually render patterns (e.g., text or shapes) in the GitHub contributions graph.
Node.js (v18+ recommended)
Git (installed and accessible in PATH)
A new or existing GitHub repository
index.js – the script that generates and commits changes daily.
data.json – temporary file written to with each commit.
package.json – dependency and metadata config.
- Clone a Private Repository
type 'git clone git@github.com:muxx3/commitGen.git' in your terminal
cd commitGen
- Install Dependencies
npm install
- Run the Script
node index.js
⚠ Warning: It will take time
- Push the Commits
The script automatically pushes all commits to the remote repository once complete.
Uses simple-git to automate Git.
Loops over every day of 2006.
For each day:
Writes a JSON object to a file (data.json).
Commits that file up to 100 times with backdated timestamps.
Pushes all commits to the remote repo.
Modify makeCommitsForDay(date, count) to vary commit counts per day.
Use a 2D matrix to "draw" text or shapes by mapping dates to commit intensity.
Target different years by changing START_DATE and END_DATE.

Let me know if you’d like a version with ASCII preview or an art matrix feature next.
