Blueprint-Mounted REST Resources
Mount an Api on a blueprint cleanly.
Blueprint-Mounted REST Resources is a free Flask Academy lesson on CoddyKit — lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Flask Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
APIs Grow, So Modularize
As your API expands, keep it tidy by mounting resources on a blueprint instead of the global app. 🧱
Why a Blueprint Here
A blueprint groups related routes and can carry a URL prefix, keeping every API endpoint under one namespace.
Create the Blueprint
Define a Blueprint for your API. Give it a name and the import name so Flask can locate it.
from flask import Blueprint
api_bp = Blueprint("api", __name__)Bind the Api to It
Pass the blueprint to Api instead of the app. Now resources attach to the blueprint, not the whole app.
from flask_restful import Api
api = Api(api_bp)Add Resources as Usual
Mount resources with add_resource exactly like before. Paths here are relative to the blueprint.
api.add_resource(TaskList, "/tasks")Register with a Prefix
When you register the blueprint, add a url_prefix so every resource sits under a shared base like /api.
app.register_blueprint(api_bp, url_prefix="/api")The Full URL
A resource at /tasks on a blueprint prefixed with /api answers at /api/tasks. Prefix plus path combine.
Keep It in Its Own Module
Put the blueprint and its resources in a separate file, then import and register it where you build the app.
from .api import api_bp
app.register_blueprint(api_bp)Pairs With the App Factory
Inside create_app, register the API blueprint alongside others. The factory becomes your single wiring point.
def create_app():
app = Flask(__name__)
app.register_blueprint(api_bp, url_prefix="/api")
return appVersion Your API
A prefix makes versioning easy: mount the same blueprint under /api/v1 and ship breaking changes safely.
app.register_blueprint(api_bp, url_prefix="/api/v1")Multiple API Blueprints
Split large APIs into several blueprints, each with its own Api and prefix, for clear ownership of each area.
Quick Check
Your blueprint is registered with url_prefix=/api and a resource sits at /tasks. What is the final URL?
Recap: Modular REST
You bound an Api to a blueprint, mounted resources, and added a prefix for clean, versionable APIs. Organized! 🎉
