feature request: order and dependency of plugins (that use js)

[fs111]

I have been playing with datasette for the last couple of weeks and it is great! I am a big fan of datasette-cluster-map and wanted to enhance it a bit with a what I would call a sub-plugin. I basically want to add more controls to the map that cluster map provides. I have been looking into its code and how the plugin management works, but it seems what I am trying to do is not doable without hacks in js.

Basically what would like to have is a way to say load my plugin after the plugins I depend on have been loaded and rendered. There seems to be no prior art where plugins have these dependencies on the js level so I was wondering if that could be added or if it exists how to do it.

Basically what I want to do is:

my-awesome-plugin has a dependency on datastte-cluster-map. Whenever datasette cluster map has finished rendering on page load, call my plugin, but no earlier. To make that work datasette probably needs some total order in which way plugins are loaded intialized.

Since I am new to datastte, I may be missing something obvious, so please let me know if the above makes no sense.

This does make sense to me. I've been hoping to significantly improve the way JavaScript plugins work - there are some notes on that here:

• JavaScript plugin hooks mechanism similar to pluggy #983

Encouraging plugins such as datasette-cluster-map to emit events that can then be listened to by other plugins is a really interesting idea that I hadn't considered.
