import “packages” from “this” project

from init import app, db, cors # Definitions initialization

setup APIs

from api.covid import covid_api # Blueprint import api definition from api.joke import joke_api # Blueprint import api definition from api.user import user_api # Blueprint import api definition from api.player import player_api from api.stock import stock_api

database migrations

from model.users import initUsers from model.players import initPlayers

setup App pages

from projects.projects import app_projects # Blueprint directory import projects definition

Initialize the SQLAlchemy object to work with the Flask app instance

db.init_app(app)

register URIs

app.register_blueprint(joke_api) # register api routes app.register_blueprint(covid_api) # register api routes app.register_blueprint(user_api) # register api routes app.register_blueprint(player_api) app.register_blueprint(stock_api) app.register_blueprint(app_projects) # register app pages @app.errorhandler(404) # catch for URL not found def page_not_found(e): # note that we set the 404 status explicitly return render_template(‘404.html’), 404 @app.route(‘/’) # connects default URL to index() function def index(): return render_template(“index.html”) @app.route(‘/table/’) # connects /stub/ URL to stub() function def table(): return render_template(“table.html”) @app.before_request def before_request(): # Check if the request came from a specific origin allowed_origin = request.headers.get(‘Origin’) if allowed_origin in [‘http://localhost:4100’, ‘http://127.0.0.1:4100’, ‘https://nighthawkcoders.github.io’]: cors._origins = allowed_origin

Create an AppGroup for custom commands

custom_cli = AppGroup(‘custom’, help=’Custom commands’)

Define a command to generate data

@custom_cli.command(‘generate_data’) def generate_data(): initUsers() initPlayers()

Register the custom command group with the Flask application

app.cli.add_command(custom_cli)

this runs the application on the development server

if name == “main”: # change name for testing app.run(debug=True, host=”0.0.0.0”, port=”8055”)
