I just did a github search for `user:simonw ""def extra_js_urls(""` ! Though I'm sure other plugins made by people other than Simon also exist out there https://github.com/search?q=user%3Asimonw+%22def+extra_js_urls%28%22&type=code","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1651082214,

- Can we move `datasette/static/table-example-plugins.js` into `demos/plugins/static`?
- For `datasetteManager.VERSION`, can we fill that in or just comment it out for now? Not sure how difficult it'll be to inject it server-side. I imagine we could also have a small build process with esbuild/rollup that just injects a version string into `manager.js` directly, so we don't have to worry about server-rendering (but that can be a future PR)

In terms of how to integrate this into Datasette, a few options I can see working:

- Push this as-is and figure it out before the next release
- Hide this feature behind a settings flag (`--setting unstable-js-plugins on`) and use that setting to hide/show `<script src=""{{ urls.static('datasette-manager.js') }}"" defer></script>` in `base.html`

I'll let @simonw decide which one to work with. I kindof like the idea of having an ""unstable"" opt-in process to enable JS plugins, to give us time to try it out with a wide variety of plugins until we feel its ready.

I'm also curious to see how ""plugins for a plugin' would work, like #1542. For example, if the leaflet plugin showed default markers, but also included its own hook for other plugins to add more markers/styling. I'm imagine that the individual plugin would re-create their own plugin system compared to this, since handling ""plugins of plugins"" at the top with Datasette seems really convoluted. 

Also for posterity, here's a list of Simon's Datasette plugins that use ""extra_js_urls()"", which probably means they can be ported/re-written to use this new plugin system:
