Parcel: 🙋 Support image meta tags

[jaredpalmer]

Feature Request

🤔 Expected Behavior

If I include a <meta name="og:image" content="./cover.jpg">, in an index.html, i'd expect that the source path gets properly updated after a successful build.

<meta name="og:image" content="./cover.jpg" />

would become

<meta name="og:image" content="./123414523412341234.jpg" />

😯 Current Behavior

meta tags with references to assets are not updated

🌍 Your Environment

| Operating System | macOs

Any more meta tags you can think about that can contain assets?
It would help add full support for all meta names that can contain assets

Expanding the scope of this ticket slightly, it appears support is missing for <use> tags, which also produce a dependency. e.g.:

<svg class="icon -facebook" viewBox="0 0 32 32">
  <use xlink:href="./src/sprite.svg#facebook">
</svg>

Do you have any workaround before this feature is shipped?

[Kjwon15]

@dmgawel I just copy directly into out dir after build.

[dmgawel]

@gregkohn <use> tags support is resolved by #612.

~Throwing this here... nobody had an issue with twitter:image tag having to be a full URL instead of relative??~ nevermind, fixed it by cp the image that I needed so it doesn't have the hash.

This solution won't work - og:image content url must be full URL (relative path won't work).

[lukechilds]

@mtskf I got stuck with this and created a plugin to manually set og:image as an absolute URL.

Not the cleanest solution, would be great if we could do this directly in parcel, but it works.
