Simple PWA HTML tags.

If you don't need the fancy features of a service worker and just want your SPA to behave nicely when a user adds to homescreen, or creates a desktop Chrome shortcut, these are the bare minimum HTML tags needed (not including the title, charset and other usual tags you would also have.)

Description and Image tags are useful for sharing purposes.

/*

This 'Observer' component expects the attrs described below.
The vdom rendered by `view` will re-render normally within
Mithril's redraw cycle.
The vdom rendered by `render` will only re-render when the
data stream updates. This will not trigger global redraws.
`render` renders into the dom node described by `selector`,
otherwise defaults to the component's root node.

deserialize

A deserialization method to be applied to the xhr.responseText. Defaults to a small wrapper around JSON.parse that returns null for empty responses. If extract is defined, deserialize will be skipped.

extract

A hook to specify how the XMLHttpRequest response should be read. Useful for processing response data, reading headers and cookies. By default this is a function that returns xhr.responseText, which is in turn passed to deserialize. If a custom extract callback is provided, the xhr parameter is the XMLHttpRequest instance used for the request, and options is the object that was passed to the m.request call. Additionally, deserialize will be skipped and the value returned from the extract callback will not automatically be parsed as JSON.
