Installation

  • Install Python 3.11
  • Create your virtual environment (venv)
  • Install dependencies
pip3 install -r requirements.txt [--upgrade]

If you get errors installing psycopg2 into a virtual env on OSX, try a tip from https://stackoverflow.com/questions/9678408/cant-install-psycopg2-with-pip-in-virtualenv-on-mac-os-x-10-7

brew install openssl
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

and retry the install.

libmagic is used to determine content type on file assets.

brew install libmagic

Front-end dependencies

npm install

Create Postgres user and databases

createuser squiggy --no-createdb --no-superuser --no-createrole --pwprompt
createdb squiggy --owner=squiggy
createdb squiggy_test --owner=squiggy

# Load schema
export FLASK_APP=application.py
flask initdb

Create local configurations

If you plan to use any resources outside localhost, put your configurations in a separately encrypted area:

mkdir /Volumes/XYZ/squiggy_config
export SQUIGGY_LOCAL_CONFIGS=/Volumes/XYZ/squiggy_config

In your development_local.py, set a bookmarklet encryption key

BOOKMARKLET_ENCRYPTION_KEY = b'<32 character string goes here>'

Run the app locally

Start the back end: python application.py

Start the front end: npm run serve-vue

Run tests, lint the code

We use Tox for continuous integration. Under the hood, you'll find PyTest, Flake8 and ESLint. Please install NPM dependencies (see above) before running tests.

# Run all tests and linters
tox

# Pytest only
tox -e test

# Run specific test(s)
tox -e test -- tests/test_models/test_foo.py
tox -e test -- tests/test_externals/

# Linters, à la carte
tox -e lint-py
tox -e lint-vue

# Auto-fix linting errors in Vue code
tox -e lint-vue-fix

# Lint specific file(s)
tox -e lint-py -- scripts/foo.py
