Oh right, Rails does its own terser minification step, so using esbuild's minifier is just running two minifiers, which is just asking for trouble!
For some reason, running it this time on the non-Vagrant box, terser was crashing trying to read something in the minified item-page.js. Now that we don't minify, that fixes it, and the output is still minified by the end!
I do notice though that --minify does some other stuff in esbuild that I forget all of what it is. Oh well, not gonna worry about it for now!
Oh right, since we've told Rails that in development the assets path is `/dev-assets`, but the JS scripts don't know that, they're still sending requests to `/assets/thing.svg` or whatever, which is returning the prebuilt production asset if present, or nothing if not. Fixed!
Soo I think the reason adding `.digested` to the filenames like `jsbundling-rails` says to doesn't work, is because we're on an old version of Sprockets for compass-rails's sake?
I'm gonna investigate what Compass actually does for us, and see if we can delete it.
This feels a bit weird on the idioms but ehh I think it's fine… mostly just, the `assets:precompile` task is gonna call `yarn build` here, so `yarn build` needs to be production settings; but also we want not quite all those settings on in development, so there's a base task that both the prod `build` and `dev` call.
I did some refactoring while here too, of pulling the deploy scripts out of `package.json` and into `bin`, to be a bit more canonically Rails-y. (idk how canonical the colon thing is but, probably fine??)
Okay, this is much simpler than the impress-2020 version where we symlinked node_modules and stuff - Bundler is just a lot better at this lol
Right now, the app is failing to start because we don't install Node—I wasn't sure whether we'd need to and whether I was gonna precompile the assets etc
Though now that I say that out loud, I guess part of the issue might be that I'm not sure the app is running in RAILS_ENV=production, I wonder if it still wants Node in that case?? I'll flip that switch in the service file now, then commit to save my place for the day, then try again with starting the app sometime and see what it says!
Yay it's working! We set up the box, install Ruby, upload a placeholder app, set it up as a service, and get it hooked up to nginx!
Next, we'll add the script to upload the latest version of the site. We just need to slot it into `/srv/impress/current`, run `bundle install`, and that should basically be that! (Oh, and we need to compile production assets—I wonder if it's useful to do that on the dev machine instead of on the target? That might save us from needing to install Node. Or maybe we'll have to anyway!)
We add jsbuilding-rails to get esbuild running in the app, and then we copy-paste the files we need from impress-2020 into here!
I stopped at the point where it was building successfully, but it's not running correctly: it's not sure about `process.env` in `next`, and I think the right next step is to delete the NextJS deps altogether and use React Router instead.
