something I'll keep in mind: setting default variables options seems to be a common use-case for integrations. Nuxt ships with a helper for integrations to define default options easily, maybe could do the same in the future.

If userConfig?.value returned something but that something wasn't an object, I almost would want this to be an error that the user sees, instead of silently failing this check and using the default config below.
Can we do the simpler if (userConfig && userConfig.value) { here?

Actually, taking a step further back: what happens if options.path is given to the integration, but then fails to load? I'd expect that to be an error for the user to investigate & fix.
Another good reason to do this is that it should really let you simplify the code below where you're trying to handle this tricky case. For example, I think it would mean that you could just do this, below:
/* throw if options.path was given, but userConfig or userConfig.value failed to load */
const tailwindConfig = userConfing.value ?? getDefaultTailwindConfig(config.src);
if (applyAstroConfigPreset) {
tailwindConfig.presets.push(getDefaultTailwindConfig(config.src));
}

Ah, great thinking! One issue with this refactor though: it'll throw an error when a tailwind.config is missing no matter what. Ideally, it would log a human-readable error specifically when you pass a bad config.path. Made a refactor here.
I swear I'll remember this by like... week 8 😆 |
lol when you figure it out please let me know your secret :) |

So if I'm reading this correctly, tailwindConfig becomes:
{
...tailwindConfig,
presets: [...tailwindConfig.presets, getDefaultTailwindConfig(config.src)]
}
does this make sense? It feels odd to put the entire default tailwind config here as a preset. If this is expected, a comment would help future readers not get confused.

Yep, just realized this was confusing! Added a clarifying comment here, and only applied the preset when a user config is present (otherwise we're applying the default config twice).

Update: discovered that adding a preset removed Tailwind's default config. Thought they would merge 😕 Used the resolveConfig function to merge those defaults back in! 19f29cb
