⚙️ Using GitHub Action on a profile repository (~10 min)

Setup a GitHub Action which runs periodically and pushes generated images to a repository.

0️ Setup a personal repository

Create a repository with the same name as your GitHub login (if it doesn't exist).

Its README.md will be displayed on your user profile:

1️ Create a GitHub personal token

💡 A GitHub personal token is required since this action will fetch data that cannot be accessed through repository-scoped tokens (like ${{ secrets.GITHUB_TOKEN }} or ${{ github.token }}) such as users, organizations, issues, pull requests, comments, commits, activity, etc.

From the Developer settings of your account settings, select Personal access tokens to create a new token.

No scopes are required, but additional one may be required depending on which features will be used. Each plugin documentation enumerates which scopes are required to make it work.

As a general rule, the following scopes may be required:

• public_repo for some plugins
• read:org for all organizations related metrics
• repo for all private repositories related metrics
  • read:user for some private repositories related metrics
• read:packages for some packages related metrics
• read:project for some projects related metrics
• gist for publishing renders to gists instead of a repository

💡 For security reasons, it is advised to always use the least amount of scopes. It is possible to prevent security issues by forking this repository and using it in your workflow instead (more information available in step 3)

A scope-less token can still display private contributions by enabling Include private contributions on my profile in account settings:

When a plugin has not enough scopes to operate (and plugins_errors_fatal is disabled), an error will be reported in the rendering like below:

2️ Put your GitHub personal token in repository secrets

Go to the Settings of your repository and to create a new secret and paste your freshly generated GitHub token there.

3️ Setup GitHub Action workflow

Create a new workflow from the Actions tab of repository and paste the following:

name: Metrics
on:
  # Schedule daily updates
  schedule: [{cron: "0 0 * * *"}]
  # (optional) Run workflow manually
  workflow_dispatch:
  # (optional) Run workflow when pushing on master/main
  push: {branches: ["master", "main"]}
jobs:
  github-metrics:
    runs-on: ubuntu-latest
    permissions:
      contents: write
    steps:
      - uses: lowlighter/metrics@latest
        with:
          token: ${{ secrets.METRICS_TOKEN }}

Default output action is to commit rendered metrics to target repository on each run.

Use output_action to change this behaviour to use either pull requests, gists or manually handle renders.

3️.1️ Choosing between @latest, @master/@main, a fork or a pinned version

There are several metrics versions that can be used in workflows:

• @latest
  • ✔️ Stable version
• @master/@main
  • ✔️ Enjoy new features and bug fixes as they're being released
  • ✔️ Helps discovering new issues
  • ➖ Jobs may fail occasionally (watch issues and discussions for bug tracking)
• @{fork}
  • ✔️ Secure as you're in control
  • ✔️ Advised when using additional scopes in personal access token
  • ➖ Manual updates (watch new releases for updates)
• @v{x}.{x}
  • ➖ Pinned versions have no real advantages

💡 Workflows are always compatible with previous version as metrics workflow-breaking changes are never introduced. In fact, even workflows from v1.0 are still compatible!

Example: using a forked version

  - uses: user/metrics@master

⚠️ Be sure to use the default branch (@master) on forks to apply any changes made!

3️.2️ Configure metrics

Read documentation for more informations about configuration. It is advised to start with 🧱 core plugin documentation.

It is also possible to use metrics.lecoq.io to play with configuration options, preview renders and finally copy the auto-generated workflow code.

4️ Add images to your profile README.md

Update profile README.md to include rendered image (filename may differ if filename option has been set, use the correct path accordingly).

Example: add rendered image with markdown

![Metrics](/github-metrics.svg)

Example: add rendered image with html for more customization

<p align="center"><img src="/github-metrics.svg" alt="Metrics" width="400"></p>

Example: add rendered image and prevent GitHub from auto linking to the image

<picture>
  <img src="/github-metrics.svg" alt="Metrics">
</picture>

Example: add rendered image when using config_display: columns

<img src="/github-metrics.svg" alt="Metrics" width="100%">
