Custom DOM library support on Node.js (e.g. JSDOM) about nanohtml

[goto-bus-stop]

I wouldn't be opposed to a dependency injection like API like you suggest. I think to implement it, the simplest way is to:

1. move all of lib/browser.js to a new lib/dom.js file
2. wrap lib/dom.js in a big closure that takes a document argument
3. update lib/browser.js to do module.exports = require('./dom')(document)
4. add a new /dom.js module that exports ./lib/dom.js (similar to how we have /raw.js already)
5. add some tests using jsdom or whatever (that would only run on node.js versions still supported by jsdom)

then it could be released as a minor version.

I don't really wanna do it myself 🙈 but would review a PR, whether it takes the above approach or a different one!

There could be a new nanohtml/dom API that does that, but you can also do this today:

var html = require('nanohtml/lib/browser')

global.document = jsdomDocument
var el = html`
  <h1>uses jsdom</h1>
`

or:

function html (document) {
  var inner = require('nanohtml/lib/browser')
  return function (strings, ...expressions) {
    global.document = document
    var result
    try {
      return inner(strings, ...expressions)
    } finally {
      delete global.document
    }
  }
}

The maintainer of hyperhtml suggested same thing but I don't want to pollute global scope. (And I hope there be no hack modifying and de-modifying global scope.)
