init_app doesn't seem to work with lifespans about fastapi-mqtt HOT 2 CLOSED

Thanks a lot for your response and explanation!

from fastapi-mqtt.

When I use a fastapi lifespan (e.g. in order to setup a db connection) the init_app method does not seem to work anymore.

Is it an error on my part with using the lifespan?

Hi @ChrsPi, it's normal. When using a lifespan method to setup, yield, and shutdown the app, that init_app method is not called anymore, and the connection and disconnection has to be called the way you do in the snippet 👍

Take into account that disconnections and re-connections to the MQTT broker are also not managed by default, but you can define callbacks with @mqtt.on_connect() and @mqtt.on_disconnect() decorators to manage those events

Otherwise adding a hint for this to the official documentation will help others.

For sure! PRs to improve docs are always welcome 🙏
