How can I automate route prefixing in Flask?

Automating Route Prefixing in Flask

Adding prefixes to Flask routes can be a hassle when managing several routes. Manually setting prefixes limits your flexibility and increases the risk of errors. Exploring an automated approach can streamline your development workflow.

In Flask, blueprints provide a solution to this challenge. By grouping related views together in a blueprint, you can apply a prefix to all routes within that blueprint.

Consider the following Python code:

bp = Blueprint('burritos', __name__,
                        template_folder='templates')

@bp.route("/")
def index_page():
  return "This is a website about burritos"

@bp.route("/about")
def about_page():
  return "This is a website about burritos"

This code defines a blueprint named 'burritos' with two routes: '/' and '/about'. Now, you can register this blueprint with your Flask application, specifying the desired prefix:

app = Flask(__name__)
app.register_blueprint(bp, url_prefix='/abc/123')

With this configuration, all routes in the 'burritos' blueprint will automatically have the prefix '/abc/123' applied. Consequently, accessing 'index_page' requires the URL '/abc/123/' instead of just '/', and '/about_page' is accessed through '/abc/123/about'.
