Dapr Python SDK integration with Flask

How to create Dapr Python virtual actors with the Flask extension

The Dapr Python SDK provides integration with Flask using the flask-dapr extension.

Installation

You can download and install the Dapr Flask extension with:

• Stable
• Development

pip install flask-dapr

Note

The development package will contain features and behavior that will be compatible with the pre-release version of the Dapr runtime. Make sure to uninstall any stable versions of the Python SDK extension before installing the <code>dapr-dev</code> package.

pip install flask-dapr-dev

Example

from flask import Flask
from flask_dapr.actor import DaprActor
from dapr.conf import settings
from demo_actor import DemoActor
app = Flask(f'{DemoActor.__name__}Service')
# Enable DaprActor Flask extension
actor = DaprActor(app)
# Register DemoActor
actor.register_actor(DemoActor)
# Setup method route
@app.route('/GetMyData', methods=['GET'])
def get_my_data():
    return {'message': 'myData'}, 200
# Run application
if __name__ == '__main__':
    app.run(port=settings.HTTP_APP_PORT)
