pyweb

This project is the backbone for the web applications.

Technology

We take advantage of various technologies here

• We host static files with Whitenoise.

  # add whitenoise
  server.wsgi_app = WhiteNoise(server.wsgi_app, root='/static', prefix='assets/')

• We use the Waitress server.

  #!/usr/bin/env python3
  from waitress import serve
  from pyweb.app import create_app
  
  
  if __name__ == '__main__':
      serve(app=create_app(), port=8000)

• The flask application is relying on the popular blueprint concept. We expose a REST server for performance calculations. Applications built on this package can reuse the very same blueprints and remain slim and elegant.

  def create_app():
      server = create_server(extensions=[engine, cache], static_folder="/static")
  
      server.register_blueprint(blue_whoosh, url_prefix="/whoosh")
      server.register_blueprint(blue_post, url_prefix="/engine")
      server.register_blueprint(blue_admin, url_prefix="/admin")
  
      # add whitenoise
      server.wsgi_app = WhiteNoise(server.wsgi_app, root='/static', prefix='assets/')
  
      return server

• We use Flask extensions and a central settings.cfg file to initialize the extensions only once. Within the Dockerfile we set

  ENV APPLICATION_SETTINGS="/server/config/settings.cfg"

• We extensively test the app and achieve a full coverage score. We test against a client created as a pytest fixture.

  @pytest.fixture(scope="module")
  def client():
      app = create_app()
  
      with app.app_context():
          __init_session()
  
      yield app.test_client()

• We use httpie within the Docker image for simple testing and debugging
