Blueprints for Organization - benhall/flask-demo

In the “flask-demo” project, “Blueprints for Organization” are used to organize the application into different modules. Blueprints are a way to organize reusable code in a Flask application. They are essentially a reusable piece of a web application, with their own routes, templates, and static files.

Here are the possible options for using Blueprints in the “flask-demo” project:

  1. Data Blueprint: This blueprint contains all the functionality related to data handling in the application. The file blueprints/data.py contains the definition of this blueprint. It includes routes for creating, retrieving, updating, and deleting data.

Example:

from flask import Blueprint

data_blueprint = Blueprint('data', __name__, template_folder='templates')

@data_blueprint.route('/data', methods=['POST'])
def create_data():
# code for creating data
  1. Greetings Blueprint: This blueprint contains all the functionality related to greetings in the application. The file blueprints/greetings.py contains the definition of this blueprint. It includes routes for displaying greetings and adding new greetings.

Example:

from flask import Blueprint

greetings_blueprint = Blueprint('greetings', __name__, template_folder='templates')

@greetings_blueprint.route('/greetings', methods=['GET'])
def display_greetings():
# code for displaying greetings

@greetings_blueprint.route('/greetings', methods=['POST'])
def add_greeting():
# code for adding a new greeting
  1. Main Blueprint: This is the main blueprint of the application, which ties all the other blueprints together. The file app.py contains the definition of this blueprint. It includes routes for displaying the home page and handling login and logout.

Example:

from flask import Flask
from blueprints.data import data_blueprint
from blueprints.greetings import greetings_blueprint

app = Flask(__name__)
app.register_blueprint(data_blueprint)
app.register_blueprint(greetings_blueprint)

@app.route('/')
def home():
# code for displaying the home page

@app.route('/login', methods=['POST'])
def login():
# code for handling login

@app.route('/logout', methods=['POST'])
def logout():
# code for handling logout
