Imp.import_blueprint

import_blueprint(self, blueprint: str) -> None

---

Import a specified Flask-Imp or standard Flask Blueprint relative to the Flask app root.

app
├── my_blueprint
│   ├── ...
│   └── __init__.py
├── ...
└── __init__.py

File: app/__init__.py

from flask import Flask

from flask_imp import Imp

imp = Imp()


def create_app():
    app = Flask(
        __name__,
        static_folder="static",
        template_folder="templates"
    )
    imp.init_app(app)

    imp.import_blueprint("my_blueprint")

    return app

Flask-Imp Blueprints have the ability to auto import resources, and initialize session variables.

For more information on how Flask-Imp Blueprints work, see the ImpBlueprint / Introduction

Example of ‘my_blueprint’ as a Flask-Imp Blueprint:

app
├── my_blueprint
│   ├── routes
│   │   └── index.py
│   ├── static
│   │   └── css
│   │       └── style.css
│   ├── templates
│   │   └── my_blueprint
│   │       └── index.html
│   ├── __init__.py
│   └── config.toml
└── ...

File: __init__.py

from flask_imp import ImpBlueprint
from flask_imp.config import ImpBlueprintConfig

bp = ImpBlueprint(
    __name__,
    ImpBlueprintConfig(
        enabled=True,
        url_prefix="/my-blueprint",
        static_folder="static",
        template_folder="templates",
        static_url_path="/static/my_blueprint",
        init_session={"my_blueprint": "session_value"},
    ),
)

bp.import_resources("routes")

File: routes / index.py

from .. import bp


@bp.route("/")
def index():
    return "regular_blueprint"

Example of ‘my_blueprint’ as a standard Flask Blueprint:

app
├── my_blueprint
│   ├── ...
│   └── __init__.py
└── ...

File: __init__.py

from flask import Blueprint

bp = Blueprint("my_blueprint", __name__, url_prefix="/my-blueprint")


@bp.route("/")
def index():
    return "regular_blueprint"

Both of the above examples will work with imp.import_blueprint("my_blueprint"), they will be registered with the Flask app, and will be accessible via url_for("my_blueprint.index").
