How to Automatically Prefix Flask Routes?

How to Prefix Flask Routes

When dealing with a Flask application, it can be tedious to manually add a prefix to every route definition. This article presents a solution to automatically prefix all routes with a desired value.

In a Flask application, you can organize routes into blueprints. Each blueprint encapsulates a collection of related views and routes. By placing routes within a blueprint, you can assign a common prefix to them.

Code Example

Here's an example of how to use a blueprint to prefix all routes with "/abc/123":

# Create a blueprint
bp = Blueprint('burritos', __name__, template_folder='templates')

# Define routes within the blueprint
@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"

# Register the blueprint with the Flask app
app = Flask(__name__)
app.register_blueprint(bp, url_prefix='/abc/123')

By prefixing the blueprint with "/abc/123," all routes within the blueprint will automatically have that prefix applied. This eliminates the need to manually add the prefix to each route definition.
