Analytics

Overview

Stay up to date with hiero organisation activity and contributor diversity

This repository provides analytics for the Hiero repositories.

Setting Up Analytics Development

Repository Setup

Before you begin, make sure you have:

• Git installed (Download Git)
• Python 3.10+ installed (Download Python)
• A GitHub account (Sign up)

Step 1: Fork the Repository

Forking creates your own copy of the Hiero Python SDK that you can modify freely.

• Go to https://github.com/hiero-hackers/analytics
• Click the Fork button in the top-right corner
• Select your GitHub account as the destination

You now have your own fork at https://github.com/YOUR_USERNAME/hiero-hackers/analytics

Step 2: Clone Your Fork

Clone your fork to your local machine:

git clone https://github.com/YOUR_USERNAME/hiero-hackers/analytics.git
cd hiero-hackers/analytics

Replace YOUR_USERNAME with your actual GitHub username.

Step 3: Add Upstream Remote

Connect your local repository to the original repository. This allows you to keep your fork synchronized with the latest changes.

git remote add upstream https://github.com/hiero-hackers/analytics.git

What this does:

• origin = your fork (where you push your changes)
• upstream = the original repository (where you pull updates from)

Step 4: Verify Your Remotes

Check that both remotes are configured correctly:

git remote -v

You should see:

origin    https://github.com/YOUR_USERNAME/hiero-hackers/analytics.git (fetch) origin    https://github.com/YOUR_USERNAME/hiero-hackers/analytics.git (push) upstream  https://github.com/hiero-hackers/analytics.git (fetch) upstream  https://github.com/hiero-hackers/analytics.git (push)

Installation

Install uv

On macOS/Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

On macOS (using Homebrew):

brew install uv

On Windows:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Other installation methods: uv Installation Guide

Verify Installation

uv --version

Install Dependencies

uv automatically manages the correct Python version based on the .python-version file in the project, so you don't need to worry about version conflicts.

Install project dependencies:

uv sync

What this does:

• Downloads and installs the correct Python version (if needed)
• Creates a virtual environment
• Installs all project dependencies
• Installs development tools (pytest, ruff, etc.)

Environment Setup

Create a fine-grained personal access token Personal Acess Tokens Info and Create Personal Access Token. Enable it for public repositorites and do not enable any extra access.

Create a .env file in the project root, copy and save your token.

GITHUB_TOKEN=yours

You'll need this token to increase your API rate limit when interacting with Github data.

Test Setup

Run the test suite to ensure everything is working:

uv run pytest

Running the Analytics

With your GITHUB_TOKEN configured (see Environment Setup), run every analytics pipeline with a single command:

uv run hiero-analytics

What this does:

• Runs all analytics pipelines in one process (one Python start-up instead of one per pipeline), reusing the on-disk fetch cache between pipelines
• Writes charts to outputs/charts/ and data tables to outputs/data/
• Isolates failures — if one pipeline errors it is logged and the rest still run; the command exits non-zero if any failed

This is the same command the scheduled Refresh Analytics Data workflow runs.

⏱️ The first run is slow. It fetches org-wide activity from the GitHub API (subject to rate limits), so the initial run can take several minutes. Later runs are incremental and much faster (see Incremental data fetching).

Viewing the dashboard

Just want to look? The latest refresh is published to GitHub Pages — open https://hiero-hackers.github.io/analytics/ to view it in your browser, no clone or setup required. The scheduled Refresh Analytics Data workflow rebuilds and republishes it automatically.

To build it yourself, the single-file dashboard at outputs/dashboard.html is built from the generated data — it reads the tables in outputs/data/ and the charts in outputs/charts/. Because of that:

• Generate the data first, or the dashboard will be empty. Building the dashboard with no data produces a page with nothing in it. uv run hiero-analytics already builds the dashboard as its last step, so on a fresh checkout that one command gives you data and a populated dashboard.
• To rebuild only the dashboard once the data already exists (e.g. after tweaking a label), run:

uv run python -m hieroanalytics.rundashboard

• Open outputs/dashboard.html in any browser — it's fully self-contained (no server required) and shows one tab per organization that has data.

Running a single pipeline

To run just one pipeline, invoke its module directly:

uv run python -m hieroanalytics.rungficgfiorg

Available pipelines:

| Module | What it produces | |---|---| | rungficgfi_org | Good First Issue / onboarding pipeline | | rundifficultyorgforrepo | Issue difficulty distribution | | runonboardingsignalforrepo | Onboarding signal (issues vs. contributors) | | runcontributorprofiles_repo | Per-contributor profiles | | runmaintainerpipeline_org | Maintainer pipeline by governance role | | runscorecardfor_org | OpenSSF Scorecard results | | runcodeownerand_runner | CODEOWNERS presence and CI runner usage | | runhierohackers_org | Hiero Hackers org composition and activity |

Fetched GitHub data is cached under outputs/cache/ for 24 hours, so repeated runs within a day reuse it instead of re-querying the API.

Incremental data fetching

To avoid re-downloading all of GitHub history on every run, fetching is incremental:

• The first run does a full fetch and stores a dataset under outputs/data/datasets/ (this run is the slow one).
• Later runs fetch only what changed since the last run and merge it in — much faster.
• Every 30 days (or with refresh=True) it does a full re-fetch to self-heal, so missed updates or deleted items can't accumulate.

The datasets are not committed to git — they're gitignored. Persistence is handled differently per environment:

• Locally: the dataset lives on your disk under outputs/data/datasets/. Nothing to set up — just run the pipeline. To force a clean rebuild, delete that folder.
• In CI: the scheduled workflow persists the dataset between runs via actions/cache (see .github/workflows/update-analytics.yml). If the cache is ever evicted, the next run simply does one full fetch and then resumes incrementally.

Local and CI datasets are independent — each maintains its own and stays correct on its own; you never need to sync them.
