Little tool I built for myself to export roam notes.

export-roam-note.js

window.exportRoamNote = async () => {
  const noteId = Math.round(Math.random()*10000) + '-note.md';
  const body = $('.roam-body .roam-app .roam-main .roam-article')[0].innerHTML;
  const boxUrl = 'https://mrm5dm6of9.execute-api.eu-west-1.amazonaws.com/'
    + 'production/box/get-url?filename='+noteId+'&'
    + 'contentType=text%2Fplain';
  
  const res = await fetch(boxUrl, {method: 'GET' });
  const {key, url} = await res.json();
  await fetch(url, { 
    method: "PUT", 
    body, 
    headers: {
      'Content-Type': 'text/plain', 
      'ContentEncoding': 'utf-8'
  	}
  })
  
  const noteUrl = `https://schof.co/notes/${key.replace('-note.md', '').replace('f/','').replace('/','-')}`;
  console.log(noteUrl);
  window.open(noteUrl);
}

setTimeout(() => {
  $('#export-share').length || $('.rm-topbar').append('<span id="export-share" onclick="window.exportRoamNote()">⬆️</span>')
}, 2500);

Added using the {{[[roam/js]]}} tag, with a nested code block:
