🐛: Astro should not blanket-swallow warn messges

[jasikpark]

I think that was removed in 0.14.0, we shouldn't be swallowing anything anymore.

err... looks like we are doing some console.warn trapping in build(). If you don't mind filing an issue for that, I think that's worth fixing (we could just silence the exact warnings coming from vue, instead of a blanket "swallow all")

Easy fix for anyone that wants it, you can add a callback here: https://github.com/snowpackjs/astro/blob/d6dfff6000b39f0eecb220214569aec48ff26aeb/packages/astro/src/build.ts#L74

And check for the Vue warning, otherwise call our own logging mechanism. Pseudo-code:

const release = trapWarn((...args) => {
  if(!args[0].includes('some vue message')) {
    warn(logging, 'build', ...args);
  }
})

I'm not sure what the Vue message is, you'll have to disable the trap temporarily to see what it is.

I think we fixed the Vue warning upstream, actually! We should be able to remove this entirely.
