Flask React SPA

Status

React v16 Frontend

The frontend is heavily inspired by react boilerplate, and indeed borrows a good chunk of boilerplate from it.

• 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.

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).

Ansible Production Deployment

• CentOS/RHEL 7.x
• Python 3.6 (provided by the IUS Project)
• PostgreSQL 9.6
• Redis 3.2
• NGINX + uWSGI + supervisord
• Lets Encrypt HTTPS
• Email sending via Postfix with SSL and OpenDKIM

Local Development QuickStart:

Using docker-compose

Dependencies:

• docker and docker-compose (at least docker engine v1.13)

# install
$ git clone git@github.com:briancappello/flask-react-spa.git
$ cd flask-react-spa

# configure (the defaults are fine for development)
$ edit `backend/config.example.py` and save as `backend/config.py`
$ edit `frontend/app/config.example.js` and save as `frontend/app/config.js`

# run it
$ docker-compose up --build  # grab a coffee; bootstrapping takes a while the first time

Once it's done building and everything has booted up:

• Access the app at: http://localhost:8888
• Access MailHog at: http://localhost:8025
• Access the docs at: http://localhost:5500
• Webpack Bundle Analyzer: http://localhost:5555
• The API (eg for testing with CURL): http://localhost:5000
• And last but not least, the database is exposed on port 5442

Running locally

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)

# install
$ git clone git@github.com:briancappello/flask-react-spa.git
$ cd flask-react-spa
$ mkvirtualenv -p /path/to/python3 flask_react_spa
$ pip install -r requirements.txt
$ pip install -r requirements-dev.txt  # for tests and sphinx docs

# configure
$ edit `backend/config.example.py` and save as `backend/config.py`
$ edit `frontend/app/config.example.js` and save as `frontend/app/config.js`

# set up database
$ sudo -u postgres -i psql
postgres=# CREATE USER flask_api WITH PASSWORD 'flask_api';
postgres=# CREATE DATABASE flask_api;
postgres=# GRANT ALL PRIVILEGES ON DATABASE flask_api TO flask_api;
postgres=# \q  # (quit)

# run db migrations
$ python manage.py db upgrade

# load db fixtures (optional)
$ python manage.py db fixtures fixtures.json

# frontend dev server:
$ npm install
$ npm run start

# backend dev server:
$ python manage.py run

# backend celery workers:
$ python manage.py celery worker
$ python manage.py celery beat
