Flask

Dependency injection for Flask (all versions) is available via the first-party integration wireup provides, available in wireup.integration.flask_integration.

Features:

• Automatically decorate Flask views and blueprints where the container is being used.
  • Eliminates the need for @container.autowire in views.
  • Views without container references will not be decorated.
• Expose Flask configuration in the container's parameters.

Examples

app = Flask(__name__)
app.config["FOO"] = "bar"

@app.get("/random")
def get_random(random: RandomService):
    return {"lucky_number": random.get_random()}

@app.get("/env")
def get_environment(
    is_debug: Annotated[bool, Inject(param="DEBUG")], 
    foo: Annotated[str, Inject(param="FOO")]
):
    return {"debug": is_debug, "foo": foo}


if __name__ == '__main__':
    # Initialize the integration.
    # Must be called after views and configuration have been added.
    # Pass to service_modules a list of top-level modules where your services reside.
    wireup_init_flask_integration(app, service_modules=[services])
    app.run()
