- Get familiar with Django Channels
- Start using RST for documentation (this file)
- Continue using docker and git
- If commits have been pushed to remote,
git commit --amendon them can be dangerous. docker-compose run ...creates new container. So changes in it (e.g.pip install X) don't get to the "main" container that is run withdocker-compose up.- Related to Channels:
- Consumer instance is created per connected client
- Consumer instances can talk to each other using
channel_layer- Channel layers require something like Redis as a backend (can be set up in settings file)
- There are two main entities in Channels: channels and groups
- Channel is like an id of a consumer that allows to manage interactions with other consumers
- Group is collection of channels that allows easily share events.
- Event is an activity that can be initiated by one of consumers and trigger specific action by other consumers.
- Synchronous consumers are less performant.
- Asynchronous consumers are more perfomant, especially when they don't deal with blocking functions. Calling blocking functions require using helpers from
asgiref.
