🦑 Interested to get your own ?

Try it now at metrics.lecoq.io with your GitHub username !

Because some plugins required additional configuration and setup, not all of them are available at metrics.lecoq.io, for a fully-featured experience, consider using this as a GitHub Action !

📜 How to use ?

⚙️ Using GitHub Action on your profile repo (~5 min setup)

Setup a GitHub Action which is run periodically and push a generated SVG image on your repository. See all supported options in action.yml.

Assuming your username is my-github-user, you can then embed your metrics in your personal repository's readme like below :

![GitHub metrics](https://github.com/my-github-user/my-github-user/blob/master/github-metrics.svg)

💬 How to setup ?

0. Prepare your personal repository

If you don't know yet or haven't done it yet, create a repository with the same name as your GitHub username.

The README.md of this repository will be displayed on your GitHub user profile like below :

1. Setup a GitHub token

Go to Developer settings from your GitHub account settings and select Personal access tokens to create a new token.

You'll need to create a token with the public_repo right so this GitHub Action has enough permissions to push the updated SVG metrics on your personal repository.

If you choose to use a bot account, you can put public_repo rights to the bot token and invite it as a collaborator on your personal profile repository so it has push access. This way, you can use a personnal token with no rights instead and reduce security issues.

2. Put your GitHub token in your personal repository secrets

Go to the Settings of your personal repository to create a new secret and paste your GitHub token here.

3. Create a new GitHub Action workflow on your personal repo

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

name: GitHub metrics as SVG image
on:
  # Schedule the metrics update
  schedule: [{cron: "0 * * * *"}]
  # (optional) Force update a commit occurs on master branch
  # All commits tagged with [Skip GitHub Action] are automatically ignored by this GitHub action to avoid loops
  push: {branches: "master"}
jobs:
  github-metrics:
    runs-on: ubuntu-latest
    steps:
      - uses: lowlighter/metrics@latest
        with:
          # Your GitHub token
          token: ${{ secrets.METRICS_TOKEN }}
          # See https://github.com/lowlighter/metrics/blob/master/action.yml for all options

See all supported options in action.yml.

A new SVG image will be generated and committed to your repository on each run. Because of this, the amount of your commits could be virtually increased which is probably unwanted.

To avoid this, you can use a bot token instead, which will still be able to track metrics of all your public repositories. If you want to also track your private repositories metrics, you'll need to pass a personal token with full repo permissions to your personal token, and use the committer_token parameter to pass the bot account token.

If you don't want to use a bot token, you can use the plugin_selfskip which will count out all your commits from your personal repository tagged with [Skip GitHub Action] made with your account, but these commits will still be linked to your account.

If you're using a token with additional permissions, it is advised to fork this repository. If it ever gets compromised, you'll be safe. But don't forget to check it from time to time for new features !

4. Embed the link into your README.md

Edit your README.md on your repository and link it your image :

![GitHub metrics](https://github.com/my-github-user/my-github-user/blob/master/github-metrics.svg)

💕 Using the shared instance (~1 min setup, but with limitations)

For conveniency, you can use the shared instance available at metrics.lecoq.io without any additional setup.

Assuming your username is my-github-user, you can embed your metrics in your personal repository's readme like below :

![GitHub metrics](https://metrics.lecoq.io/my-github-user)

Visit metrics.lecoq.io for more informations.

💬 Restrictions and fair use

Since GitHub API has rate limitations, the shared instance has a few limitations :

• Images are cached for 1 hour
  • Your generated metrics won't be updated during this amount of time when queried
• The rate limiter is enabled, although it won't affect already cached users metrics
• Plugins which consume additional requests, token rights or other configuration are disabled.

If you're appreciating this project, consider using it as a GitHub Action or deploy your own instance.

🏗️ Deploying your own instance (~15 min setup, depending on your sysadmin knowledge)

You can setup your own instance if you choose to not use the GitHub Action or you want to allow others users to use your instance.

You'll need to create a GitHub token to setup it, however you do not need to grant any additional permissions to your token since it won't push images to any of your repositories. You may still require additional rights for some plugins if you decide to enable them though.

If you intend to share your instance, it is advised to setup either an access list to restrict which users can use it, or to configure the rate limiter to avoid reaching the requests limit of GitHub API.

See all supported options in settings.example.json.

💬 How to setup ?

0. Prepare your server

You'll need a server where you can install and configure apps.

1. Create a GitHub token

In your account settings, go to Developer settings and select Personal access tokens to create a new token. As explained above, you do not need to grant additional permissions to the token unless you want to enable additional plugins.

2. Install the dependancies

Connect to your server and ensure NodeJS is installed (see tested versions in the build workflows).

Then run the following commands :

# Clone this repository (or your fork)
git clone https://github.com/lowlighter/metrics.git
# Install dependancies
cd metrics/
npm install --only=prod
# Copy the settings exemple
cp settings.example.json settings.json

3. Configure your instance

Open and edit settings.json to configure your instance using a text editor of your choice.

{
  //GitHub API token
    "token":"****************************************"
  //See https://github.com/lowlighter/metrics/blob/master/settings.example.json for all options
}

See all supported options in settings.example.json.

4. Start your instance

Start your instance once you've finished configuring it :

npm start

And you should be able to access it on the port you provided !

5. Embed the link into your README.md

Edit your README.md on your repository and include your metrics from your server domain :

![GitHub metrics](https://my-personal-domain.com/my-github-user)

6. (optional) Setup as service on your instance

If you want to ensure that your instance will be restarted after reboots or crashes, you should setup it as a service. This is described below for linux-like systems with systemd.

Create a new service file in /etc/systemd/system :

nano /etc/systemd/system/github_metrics.service

Paste the following and edit it with the correct paths :

[Unit]
Description=GitHub metrics
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
WorkingDirectory=/path/to/metrics
ExecStart=/usr/bin/node /path/to/metrics/index.mjs

[Install]
WantedBy=multi-user.target

Reload services, enable it, start it and check it is up and running :

systemctl daemon-reload
systemctl enable github_metrics
systemctl start github_metrics
systemctl status github_metrics

⚠️ HTTP errors code

The following errors code can be encountered if on a server instance :

• 400 Bad request : Query is invalid (e.g. unsupported template)
• 403 Forbidden : User is not allowed in restricted users list
• 404 Not found : GitHub API did not found the requested user
• 429 Too many requests : Thrown when rate limiter is trigerred
• 500 Internal error : An error ocurred while generating metrics images (logs can be seen if you're the owner of the instance)
• 503 Service unavailable : Maximum user capacity reached, only already cached images can be accessed for now

🔗 HTTP parameters

Generated metrics from a server instance may be configured through url parameters.

Base content is enabled by default, but you can pass ?base=0 to disable all base content or ?base.<section>=0 to disable a specific <section>. For example, to opt-out from activity, community and metadata, pass ?base.activity=0&base.community=0&base.metadata=0 to url.

Plugins are disabled by default, but you can pass ?<plugin>=1 to enable a specific <plugin>. For example, to enable music plugin, pass ?music=1 to url.

Plugin options can be passed with ?<plugin>.<option>=<value>. For example, to configure music plugin, you could add the following to url : ?music=1&music.provider=spotify&music.mode=recent&music.limit=4.

📚 Documentations

🖼️ Templates

Templates allows you to style your metrics. The default is the classic one, but you can change it for something more stylish.

Some metrics may be displayed differently, and it is possible that not all plugins are supported or behave the same from one template to another.

Consider trying them at metrics.lecoq.io !

🧩 Plugins

Plugins are features which are disabled by default but they can provide additional metrics. In return they may require additional configuration and tend to consume additional API requests.

🗃️ Base content

Generated metrics contains a few sections that are enabled by default, such as recent activity, community stats and repositories stats. This can be configured by explicitely opt-out from them.

💬 About

By default, generated metrics contains the following sections :

• header, which usually contains your username, your two-week commits calendars and a few additional data
• activity, which contains your recent activity (commits, pull requests, issues, etc.)
• community, which contains your community stats (following, sponsors, organizations, etc.)
• repositories, which contains your repositories stats (license, forks, stars, etc.)
• metadata, which contains informations about generated metrics

You can explicitely opt-out from them, if you want to keep only a few sections or if you want to use a plugin as standalone.

For example, to keep only header and repositories sections, add the following to your workflow :

- uses: lowlighter/metrics@latest
  with:
    # ... other options
    base: "header, repositories" # opt-out from "activity", "community" and "metadata"

⏱️ PageSpeed

The pagespeed plugin allows you to add the performances of the website attached to the GitHub user account :

These are computed through Google's PageSpeed API, which returns the same results as web.dev.

💬 About

This plugin may require an API key that you can generate here although it does not seem mandatory. It is still advised to provide it to avoid 429 HTTP errors.

The website attached to the GitHub profile will be the one to be audited. Expect 10 to 30 seconds to generate the results.

Add the following to your workflow :

- uses: lowlighter/metrics@latest
  with:
    # ... other options
    plugin_pagespeed: yes
    plugin_pagespeed_token: ${{ secrets.PAGESPEED_TOKEN }}

🎼 Music

The music plugin can work in the following modes :

Playlist mode

Select randomly a few tracks from a given playlist so you can suggest your favorite tracks to your visitors.

💬 About

Select a music provider below for instructions.

Apple Music

You will need to extract the embed url of the playlist you want to share.

Connect to music.apple.com and select the playlist you want to share. From the ... menu, select Share and Copy embed code.

Paste the code in your clipboard and extract the source link from it :

<iframe allow="" frameborder="" height="" style="" sandbox="" src="https://embed.music.apple.com/**/playlist/********"></iframe>

Once you've extracted the embed url you can finish the setup by adding the following to your workflow :

- uses: lowlighter/metrics@latest
  with:
    # ... other options
    plugin_music: yes
    plugin_music_provider: apple
    plugin_music_mode: playlist
    plugin_music_playlist: https://********
    plugin_music_limit: 4 # Set the number of tracks you want to display

Spotify

- uses: lowlighter/metrics@latest
  with:
    # ... other options
    plugin_music: yes
    plugin_music_provider: spotify
    plugin_music_mode: playlist
    plugin_music_playlist: https://********
    plugin_music_limit: 4

Recently played mode

Display the track you played recently.

💬 About

Select a music provider below for additional instructions.

Apple Music

This mode is not supported for now.

I tried to find a way with smart playlists, shortcuts and other stuff but could not figure a workaround to do it without paying the 99$ fee for developper program.

So unfortunately this isn't available for now.

Spotify

Spotify does not have personal tokens, so it makes the processus a bit longer because you're required to follow the authorization workflow... Follow the instructions below for TL;DR and obtain the refresh_token.

Sign-in to the developer dashboard and create a new app. Keep your client_id and client_secret and keep this tab open for now.

Then open the settings and add a new Redirect url. Normally you use it to setup callbacks for your apps, but since we don't have one and it is mandatory as per the authorization guide, just put https://localhost.

Next forge the url for authorization with your client_id and the encoded redirect_uri you whitelisted, and access it from your browser.

https://accounts.spotify.com/authorize?client_id=********&response_type=code&scope=user-read-recently-played&redirect_uri=https%3A%2F%2Flocalhost

When prompted, authorize your application.

Next you'll be redirected to redirect_uri. Extract the generated authorization code from your url bar.

Then go back to the developer dashboard tab, open the web console of your browser and paste the following JavaScript code, with your own client_id, client_secret, authorization code and redirect_uri.

(async () => {
  console.log(await (await fetch("https://accounts.spotify.com/api/token", {
    method:"POST",
    headers:{"Content-Type":"application/x-www-form-urlencoded"},
    body:new URLSearchParams({
      grant_type:"authorization_code",
      redirect_uri:"https://localhost",
      client_id:"********",
      client_secret:"********",
      code:"********",
    })
  })).json())
})()

It should return a JSON response with the following content :

{
  "access_token":"********",
  "expires_in": 3600,
  "scope":"user-read-recently-played",
  "token_type":"Bearer",
  "refresh_token":"********"
}

Now that you've got your client_id, client_secret and refresh_token you can finish the setup by adding the following to your workflow :

- uses: lowlighter/metrics@latest
  with:
    # ... other options
    plugin_music: yes
    plugin_music_provider: spotify
    plugin_music_token: "${{ secrets.SPOTIFY_CLIENT_ID }}, ${{ secrets.SPOTIFY_CLIENT_SECRET }}, ${{ secrets.SPOTIFY_REFRESH_TOKEN }}"
    plugin_music_mode: recent
    plugin_music_limit: 4

👨‍💻 Lines

The lines of code plugin allows you to compute the number of lines of code you added and removed across all of your repositories.

💬 About

It will consume an additional GitHub request per repository.

Add the following to your workflow :

- uses: lowlighter/metrics@latest
  with:
    # ... other options
    plugin_lines: yes

🧮 Traffic

The repositories traffic plugin allows you to compute the number of pages views across your repositories.

💬 About

It will consume an additional GitHub request per repository.

Because of GitHub REST API limitation, the provided token will require full repo permissions to access traffic informations.

Add the following to your workflow :

- uses: lowlighter/metrics@latest
  with:
    # token with "repo" rights
    token: ${{ secrets.METRICS_TOKEN }}
    # ... other options
    plugin_traffic: yes

💡 Habits

The coding habits plugin allows you to add deduced coding about based on your recent activity, from up to 100 events.

💬 About

It will consume an additional GitHub request per event fetched.

Because of GitHub REST API limitation, the provided token will require full repo permissions to access private events. By default, events that cannot be fetched will be ignored so you can still use this plugin with a public token.

Add the following to your workflow :

- uses: lowlighter/metrics@latest
  with:
    # ... other options
    plugin_habits: yes
    plugin_habits_from: 100
