Contributing

I'm open to feature suggestions and happy to review code contributions. If you are planning to contribute something larger than a small, straightforward bugfix, please open an issue so we can discuss it first. Otherwise you are risking a "no" or a "yes, but let's do it differently" to an already implemented feature.

Code Style

  • Format your Python code with black.
  • Prefer simplicity over cleverness.
  • If you are fixing a bug or adding a feature, add a test. Run tests before submitting pull requests.

Adding Documentation

This project uses the Markdown format for documentation. Use the render_docs management command to generate the HTML version of the documentation. To add a new documentation page:

  1. Create the appropriate .md file under templates/docs
  2. Generate the HTML version with ./manage.py render_docs
  3. Add the page to the navigation in /templates/front/docs_single.html

Developing a New Integration

The best way to build a new integration is to pick a similar existing integration as a starting point for the new integration and replicate every aspect of it. You will need to make changes in the following files:

  • Add a new class in /hc/api/transports.py.
  • Add a new notification template in /templates/integrations/.
  • Write testcases for the new transport class in /hc/api/tests/test_notify_<kind>.py.
  • Update CHANNEL_KINDS in /hc/api/models.py.
  • Update Channel.transport() in /hc/api/models.py.
  • Create a view for provisioning the new integration in /hc/front/views.py.
  • Write a HTML template for the new view in /templates/front/add_<kind>.py, and prepare any supporting illustrations in /static/img/integrations/.
  • Add a route for the new view in /hc/front/urls.py.
  • Write testcases for the new view in /hc/font/tests/test_add_<kind>.py.
  • Update /templates/front/channels.html – add a new section in the list of available integrations, make sure an existing integration is displayed nicely.
  • Update /templates/front/event_summary.html to make sure notifications sent to the new integration are displayed nicely.
  • Add a logo in /static/img/integrations/.
  • Update the icon font (it's a little tricky to do, I can take care of that).

If you intend to contribute the new integration to the Healthchecks project (as opposed to maintaining it in a separate fork), please open an issue and discuss it first.
