I’ve added a /lib/fish_web/live folder with a hero_component.ex and a hero_component.html.leex - and now I’m chasing the Phoenix.LiveView — Phoenix LiveView v0.20.2 and particularly where it says
You can also
live_renderfrom any template:
So I’ve added <%= live_render @conn, FishWeb.HeroComponent %> to my /lib/fish_web/templates/page/index.html.eex !
Sure enough - the wrapping div is there alright
<div data-phx-session="SFMyNTY.g2gDaAJhBHQAAAAHZAACaWRtAAAAFHBoeC1GaDJRSnM1Uk5Lajlud0FEZAAKcGFyZW50X3BpZGQAA25pbGQACHJvb3RfcGlkZAADbmlsZAAJcm9vdF92aWV3ZAAcRWxpeGlyLkZpc2hXZWIuSGVyb0NvbXBvbmVudGQABnJvdXRlcmQAA25pbGQAB3Nlc3Npb250AAAAAGQABHZpZXdkABxFbGl4aXIuRmlzaFdlYi5IZXJvQ29tcG9uZW50bgYAM1NECXMBYgABUYA.R9teP9DJXvo0CtI-3vs_slQewBd3npFAySNG8adXI_U" data-phx-static="SFMyNTY.g2gDaAJhBHQAAAADZAAKYXNzaWduX25ld2pkAAVmbGFzaHQAAAAAZAACaWRtAAAAFHBoeC1GaDJRSnM1Uk5Lajlud0FEbgYANVNECXMBYgABUYA.YimJVVUJLNLTquNglPydtN1tWdhYQnxV7K3zJmtoBHI" data-phx-view="HeroComponent" id="phx-Fh2QJs5RNKj9nwAD" class="phx-connected" data-phx-root-id="phx-Fh2QJs5RNKj9nwAD"></div>
but no content - and I change it content every 30 seconds!
I’m aware that the ‘wrapper’ has the phx-connected class - and my log does look fairly peachy I’d say?
