Flask Backend

• SQLAlchemy ORM with Flask-SQLAlchemy and migrations provided by Flask-Alembic
• RESTful APIs provided by a customized integration between Flask-RESTful and Flask-Marshmallow
• Flask-Security provides authentication, authorization, registration and change/forgot password functionality
  • User session management via Flask-Login
  • User permissions and roles via Flask-Principal
  • Secrets encryption via passlib and itsdangerous
  • CSRF protection via Flask-WTF
• Flask-Admin integrated for painless model CRUD administration
• Flask-Session for server-side sessions
• Celery for asynchronous tasks, such as sending emails via Flask-Mail

The backend is structured using the Application Factory Pattern, in conjunction with a little bit of declarative configuration in backend/config.py (for ordered registration of extensions, and auto-detection of views, models, serializers, model admins and cli commands). The entry point is the create_app() method in backend/app.py (wsgi.py in production).

React Frontend

• React Router v4
• Redux, Redux-Saga and Redux-Form for handling state and side effects
• Webpack 3 and Babel 6
  • Hot Module Reloading
  • Tree Shaking
  • Code Splitting (asynchronous components via react-loadable)

Entry point is at frontend/app/index.js.

Local Development

This assumes you're on a reasonably standard *nix system. Windows might work if you know what you're doing, but you're on your own there.

Dependencies:

• Python 3.6+
• Your virtualenv tool of choice (strongly recommended)
• PostgreSQL or MariaDB (MySQL)
• Redis (used for sessions persistence and the Celery tasks queue)
• node.js & npm (v6 or later recommended, only required for development)
• MailHog (not required, but it's awesome for testing email related tasks)
