🙈 This GitHub action will automatically push empty commits to one of your repositories.

Contribution Graph Action

Maybe most of your coding happens on another version control host, like GitLab or Bitbucket. Maybe your company uses GitHub Enterprise but hasn't enabled unified contributions. Maybe you're looking for a new software development job and are worried that recruiters will prejudge you by your scarce contribution graph.
Or maybe you have other reasons. Whatever the case may be, you've come to the right place.

Quick start without leaving your browser ⚡

1. Create a new repo (preferably private unless you have no shame)
2. Click on Create a new file
   
3. In the Name your file... field, type in .github/workflows/main.yml
4. Paste in one of the YAML file contents below, depending on what you want to do. Be sure to update GIT_EMAIL.
5. Click the Commit new file button at the bottom of the page. You're all set!
   • Note that you must enable the option below in your contribution settings for private commits to count on the graph.

If you change your mind about these commits later, you can delete the repository and they'll disappear from your contribution graph.

Push a commit to GitHub once a day 🍺

# .github/workflows/main.yml

on:
  schedule:
  - cron: '0 12 * * *' # every day at noon

jobs:
  single-commit:
    runs-on: ubuntu-latest
    permissions:
      contents: write
    steps:
    - uses: bcanseco/github-contribution-graph-action@v2
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        GIT_EMAIL: [email protected] # replace me

If you need help with cron job syntax, crontab guru is a great resource.

Backfill a year of commits whenever you push to GitHub 🍻

This rolls a pseudorandom number generator between 1 and 5 (inclusive) to determine how many commits to make per-day.

# .github/workflows/main.yml

on: push

jobs:
  backfill-commits:
    runs-on: ubuntu-latest
    permissions:
      contents: write
    steps:
    - uses: bcanseco/github-contribution-graph-action@v2
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        GIT_EMAIL: [email protected] # replace me
        MAX_DAYS: 365
        MIN_COMMITS_PER_DAY: 1
        MAX_COMMITS_PER_DAY: 5

Keep reading for more cool stuff like:

• skipping weekends/weekdays
• backfilling specific time periods
• custom commit messages
• and more!

Environment variables 🌳

How do I know this is secure? 🔒

Explore the code! It's tiny and there aren't many dependencies.

Speaking of dependencies, all production npm dependencies used by this GitHub Action are automatically audited for vulnerabilities. If the badge at the top of this README is green, you're good to go.

If you're still worried about malicious code in this repository, GitHub recommends always using a specific version of any GitHub Actions you add to your repositories. Read more.

As far as data security, there's two sensitive pieces of data that this Action handles:

• GITHUB_TOKEN
• GIT_EMAIL

GITHUB_TOKEN 🔑

GitHub has a great article about the token. It's the standard way that all GitHub Actions interact with GitHub on your behalf. The permissions of this token are both short-lived and scoped to one repo only.

You don't need to create this secret yourself; GitHub handles that for you. All you need to do is provide the token in your workflow, job, or step:

env:
  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Getting 403 errors? ❌

Make sure your token has write permission for the contents scope. If you're using the examples in this README, this is already done for you.

You can alternatively set this as a repo-level default:

GIT_EMAIL 📧

This GitHub Action requires an email associated with your GitHub account. If you provide a random or throwaway email, contributions won't show up on your GitHub profile. Read more.

Chances are, your email is already public if you're making commits with it. But if you're concerned about privacy, you can do either of the following:

• Add your email as a secret and pass it in the same way as the GITHUB_TOKEN
• Use your GitHub-provided noreply email address

Discussion for CUSTOM_TEXT feature

CUSTOM_TEXT is currently out of scope for a feature request because the proposed solution of deleting the entire repo and recreating it for the correct contribution history on a repo is outside the permissions of GITHUB_TOKEN. However, I think it's a super cool idea & I'd love to explore it more.

Unfortunately though, commits made on a GitHub repository will always show on the graph even if those commits are later removed through a force push.

According to the github contribution docs the commits that are counted in the graph are "in the repository's default branch". My first thought was that the commit history could be added to a different branch that replaces the repo's default branch, then the original default branch is deleted.

However: at a glance, it does not seem that the token is allowed to delete anything whatsoever? And It's unclear if it's allowed to change the default branch of a repo. 🤔

Default branches on github are now named "main"

'backfill-commits' fails because there is no remote branch 'master' to clone in new repositories:

warning: Could not find remote branch master to clone.
fatal: Remote branch master not found in upstream origin

Basic configuration with multiple commits per day is failling

Using below config, the server is sending thousands of commits in less than 2 minutes.:

# .github/workflows/main.yml

on:
  push:
    branches: [ master ]

jobs:
  backfill-commits:
    runs-on: ubuntu-latest
    steps:
    - uses: bcanseco/github-contribution-graph-action@master
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        GIT_EMAIL: [email protected] # replace me
        MAX_DAYS: 365
        MIN_COMMITS_PER_DAY: 1
        MAX_COMMITS_PER_DAY: 5

Expected: Maximum of 5 commits.
Tested using v1.1.0 and v1.2.0

Workflow auto starts after first push

im using back fill graph action. after the fist commit the workflow starts and then ends successfully but after an interval it starts again and then again , it keeps on committing

im using this code below
` on: push

jobs:
backfill-commits:
runs-on: ubuntu-latest
steps:
- uses: bcanseco/github-contribution-graph-action@v2
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
GIT_EMAIL: [email protected] # replace me
MAX_DAYS: 365
