Contributing

Takahē, as an open source project, could always do with more help, and if you want to contribute we'd love help in the following areas:

  • Backend code development (Python)
  • Frontend code development (HTML, CSS and very limited JavaScript)
  • Visual design & UX (for our default UI, and the project site)
  • Illustration (for the app, project site, and outreach materials)
  • Writing (for our development and user documentation)
  • Moderation (relayed advice and guidelines from those who have done it for Mastodon or others)
  • Compliance, Trust & Safety (professional advice and guidelines on what servers will require)
  • Other ActivityPub Servers (to help debug federation issues)

If you're interested in helping out, join our Discord server or email [email protected], and mention what you'd like to help with.

All contributors are expected to abide by our Code of Conduct. We have zero tolerance for bigotry or discrimination.

If you feel like someone is breaking the code of conduct, or is making you feel unwelcome in a way not explicitly outlined in it, you can email us at [email protected].

Running Locally

If you wish to run Takahē locally, these instructions will help you do that. It is worth noting, however, that this will only really let you test the UI and local posting/follow functionality; to test ActivityPub itself and follow other people, your installation must be accessible from the internet; doing that securely is different enough per person that it is not covered here.

Using Docker Compose is the fastest way to get up and running, and you will still be able to make web changes and have them appear in real-time. Direct installation is recommended for more advanced developers or those wishing to use a PostgreSQL they already have.

These instructions are not suitable for running a production copy; for that, see :doc:`installation`.

Docker

The docker build process will take care of much of the above, but you just have to be sure that you're executing it from the project root.

First, you need to build your image:

docker compose -f docker/docker-compose.yml build

Then start the compose session:

docker compose -f docker/docker-compose.yml up

At this point, you should be able to see the Web UI at http://localhost:8000

Once your session is up and running, you can:

…make yourself a superuser account:

docker compose -f docker/docker-compose.yml exec web python3 manage.py createsuperuser

…install the test dependencies inside your container:

docker compose -f docker/docker-compose.yml exec web pip install -r requirements-dev.txt

…run the tests inside your container:

docker compose -f docker/docker-compose.yml exec web pytest

If you want to change the settings that Takahē is using, you can edit them near the top of the docker-compose file; the default set are designed for a local installation, though.

Direct installation

Takahē requires Python 3.10 or above, so you'll need that first. Clone the repo:

git clone https://github.com/jointakahe/takahe/

Then, cd into that directory and create and activate a virtual environment (you can use other options, but this is the basic example):

python3 -m venv .venv
. .venv/bin/activate

Then install the development requirements:

python3 -m pip install -r requirements-dev.txt

Enable the git commit hooks to do auto-formatting and linting (if you don't do this, our CI system will reject your PRs until they match):

python3 -m pre_commit install

Create a databse in your local PostgreSQL instance:

sudo -u postgres createdb takahe

You will need to set up some (i.e. TAKAHE_DATABASE_SERVER) development settings (you can edit .env later):

cp development.env .env

Now you can apply migrations:

python3 -m manage migrate

You can run the web interface to see it at http://localhost:8000:

python3 -m manage runserver

You will need to run Stator in order to have background actions work:

python3 -m manage runstator

Make yourself a superuser account in order to log in:

python3 -m manage createsuperuser

And you can run the tests with pytest:

python3 -m pytest

If you want to edit settings, you can edit the .env file.

Building Documentation

We are using Sphinx and reStructuredText markup language to write documentation.

To build documentation, we need to install additional libraries:

pip install -r docs/requirements.txt

After editing documentation, you can build documentation with the following command:

make docs

This outputs HTML files under the docs/_build/html/ directory. Let's launch a development server to serve HTML files:

python -m http.server 8000 --directory docs/_build/html/

Now, you can view the documentation on your browser at http://localhost:8000/.

Coding Guidelines

We have linters, typechecking and formatters enabled for the project; ensure these are set up locally by running python3 -m pre_commit install, otherwise your pull request will fail its testing phase.

Comment anything weird, unusual or complicated; if in doubt, leave a comment.

Don't use overly complex language constructs - like double-nested list comprehensions - when a simple, understandable version is possible instead. We optimise for code readability.

All features should be accessible without JavaScript if at all possible; this doesn't mean that we can't have nice JavaScript user interfaces and affordances, but all basic functionality should be accessible without it.

We use HTMX for dynamically loading content, and Hyperscript for most interactions rather than raw JavaScript. If you can accomplish what you need with these tools, please use them rather than adding JS.
