If you don't have NodeJS on your system, install it with homebrew.

brew install node

nvm is a tool for managing different versions of NodeJS. Follow the guidance on nvm's github repository to install it.

Once installed, run the following to switch to the version of NodeJS for this project. If you don't have that version, it should tell you how to install it.

nvm use

In the root directory of the application, run:

echo "
export NOTIFY_ENVIRONMENT='development'
export FLASK_APP=application.py
export FLASK_DEBUG=1
export WERKZEUG_DEBUG_PIN=off
"> environment.sh

To run parts of the app, such as uploading letters, you will need appropriate AWS credentials. See the Wiki for more details.

We use uv for Python dependency management. Follow the install instructions or run:

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

We use pre-commit to ensure that committed code meets basic standards for formatting, and will make basic fixes for you to save time and aggravation.

Install pre-commit system-wide with, eg brew install pre-commit. Then, install the hooks in this repository with pre-commit install --install-hooks.

# install dependencies, etc.
make bootstrap

# run the web app
make run-flask

Then visit localhost:6012.

Any Python code changes you make should be picked up automatically in development. If you're developing JavaScript or CSS code, run make watch-frontend to achieve the same.

# install dependencies, etc.
make bootstrap

# run all the tests
make test

# run the js tests
npx jest

# run a single js test
npx jest <pathToAJavascriptTestfile>

# continuously run js tests
npm run test-watch

# debug a js test in chrome
npm run debug --test=[name of test file]

To run a specific JavaScript test, you'll need to copy the full command from package.json.
