CSharp

Run brew install --cask dotnet-sdk to get started. This will install the SDK along with Mono. See the C# page for more information: https://formulae.brew.sh/cask/dotnet-sdk

Multisite Docker Server via Traefik

Quickly setup multiple websites via Docker containers on a single server via Traefik.

Edit the email found in the traefik.toml file and run docker compose up -d to get started in production (LetsEncrypt will generate SSL certs for all your sites).

If you'd like to use Traefik during development, you'll want to comment out the lines that have SSL/HTTPS/443 comments/code in the docker-compose.yml file.

Hosts: You'll need to add each site url to your /etc/hosts file before it can be visited.

Package non-Python Assets into your Python Package

There are times where you may need to include non-Python assets in your Python package for distribution. This may include data files or JSON assets from a submodule for example that your Python package needs to reference. By default, Python will not include these assets in the bdist/sdist. You can either include an empty __init__.py file in that submodule (even if the project isn't Python) and rely on the magic of packages=setuptools.find_packages() in setup.py or you can explicitly include those non-Python assets by using the following steps.

1. In setup.py, include an array of locations to include. These are glob matching patterns. An example of this looks like the following:

package_data={
    'top_level_package': [
 'path/to/assets/one/*.json',
