Eta - Defer File

A plugin for the Eta template engine to defer async includes. The defered includes are loaded simultaneously with Promise.all.

Without the plugin

<%
const [AsyncComponent1, AsyncComponent2] = await Promise.all([
  includeFile('AsyncComponent.eta', { delay: 200 }),
  includeFile('AsyncComponent.eta', { delay: 300 })
])
%>
<h1>This should take ~300ms</h1>
<%~ AsyncComponent1 %>
<%~ AsyncComponent2 %>

With the plugin:

<h1>Test Page</h1>
<%~ deferFile('async.eta', { delay: 200 }) %>
<%~ deferFile('async.eta', { delay: 300 }) %>
