Hi!
To make it easier to develop LiveComponents that require information from the current context of the LiveView it would be awesome if the LiveComponent.mount/1 could receive the assigns from the LiveView that contains the component.
A real-world example is the need to get the current_user that one may store in the assigns of the LiveView
Alternative could be to add a second mount/2 where the second argument is the parent socket or assigns
I know that you can give this as arguments when using <.live_component module={MyLiveComponent} id="myid" current_user={@current_user} /> and this will be params to the update/2 function in the component.
But sometimes you would like to load some assigns in the component only once and not everytime the page has updates that then triggers the update/2 function in the component
Where Next?

You can compare what is stored in
socket.assignswith the data privided by theassignsparameter ofupdate/2to figure out if you want to rerun some calculation or not.mortenlund
Yes this is what I currently do
Would just be intuitive if you could think of
mountas “setup” function and then only supply contextual changes to the component using theupdatefunction
