How to Use It

• runs in the browser using browserify

To Do

• – absorb µ.keyboard-modifier-emitter.js (svelte app2)
• – absorb src/components/Toolbox/index.svelte#µ_DOM_detect_doublekey_events()
• – documentation
• – offer browserified builds
• – allow lists of elements with event binding
• – include things like computedStyleMap(), attributeStyleMap, computedStyleMap() from CSS Houdini
  • https://www.smashingmagazine.com/2020/03/practical-overview-css-houdini/
  • https://web.dev/houdini-how/?utm_campaign=CSS%2BLayout%2BNews&utm_medium=web&utm_source=CSS_Layout_News_281
  • https://web.dev/css-props-and-vals/
  • https://houdini.how/
• – export classes Dom, Text, &c.

• – this should work but doesn't:

  sub_document  = iframe.contentDocument
  first_tracker = µ.DOM.select_first_from sub_document, '.tracker'

  Error message is not a valid delement: HTMLDocument{...; suspicion is that HTMLDocument should be accepted as a (DOM) element

  Note the real problem is not the test x instanceof Element, the problem lies in the realm-crossing nature of the <iframe> element

  • solution might be to just check for presence of relevant API (like element.querySelectorAll?)

• – allow to instantiate with virtual DOM object so µDOM can be used outside the browser

• – integrate XPath &c from playlist µDOM2
• – remove µ.DOM.select_*_from() methods; instead allow µ.DOM.select_first(), µ.DOM.select_all() to take one or two parameters
• – ??? allow to pass in document on creation as it can differ from main document within iframes
• – don't reference µ from with libraries, use private ref to avoid name collisions
• – move loupe.js to deps

• – integrate method to monitor all events in document or on given element as discussed in https://stackoverflow.com/a/72945018:

  for (const key in document) if (key.startsWith('on')) document.addEventListener(key.slice(2), console.log);

  // https://stackoverflow.com/a/72945018/319266
  function monitorEvents(element) {
    for (const key in element) {
      if (key.startsWith('on')) {
        element.addEventListener(key.slice(2), console.log);
      }
    }
  }
