Make sure you have poetry installed on your machine.

# make install
poetry install

# Optional: Installing dependencies only
poetry install --no-root

# Optional: Updating dependencies to their latest versions
poetry update

To run on debug mode locally on your browser:

# make dev
poetry run python3 main.py --debug=True --port=8080

Then, visit http://localhost:8080/ on your browser.

Before you begin your development work, make sure you have installed pre-commit hooks.

Some example useful invocations:

• pre-commit install: Default invocation. Installs the pre-commit script alongside any existing git hooks.
• pre-commit install --install-hooks --overwrite: Idempotently replaces existing git hook scripts with pre-commit, and also installs hook environments.
• pre-commit run: Run hooks.

Check this out.

To generate a requirements.txt file:

# This command exports the poetry lock file to other formats.
# make generate
poetry export -f requirements.txt --output requirements.txt
