seo

Helpers for building SEO-friendly Web pages in Angel. The goal of package:angel_seo is to speed up perceived client page loads, prevent the infamous flash of unstyled content, and other SEO optimizations that can easily become tedious to perform by hand.

inlineAssets

This function is a simple one; it wraps a VirtualDirectory to patch the way it sends .html files.

In any .html file sent down, link and script elements that point to internal resources will have the contents of said file read, and inlined into the HTML page itself.

In this case, "internal resources" refers to a URI without a scheme, i.e. /site.css or foo/bar/baz.js.
