A small library that can produce a JSON compatible serialization of a DOM tree which can then be reinflated. Useful for creating static copies of applications to reproduce layout or style bugs, or create test case reductions.

• Shadow DOM v0 and v1.
• HTML imports.
• Standards and quirks mode.
• Strips most script and side effect causing things.
• Requires ES6+, supports Chrome 56+.

// The serialization format can be stringified into JSON or sent over
// postMessage. It's both JSON and structured clone compatible.
let data = DOMPickle.serialize(node);
// worker.postMessage(data);
// localStorage.setItem("pickle", JSON.stringify(data));

// We can reinflate it into a real DOM tree as well.
let newNode = DOMPickle.inflate(data);

Currently tested on: DevTools UI, Google Music.

May also be useful for experimenting with creating dom inside workers, though no API exists currently to create the serialization format from inside a worker.
