Banglejs connect and share information from/to website

a way to send text from the website to the banglejs app

Are you running your own app? If so, just define a function called myFunction and then send the code to call that. For example in the Bangle.js:

function myFunction(txt) {
  g.clear(1);
  g.setFont("Vector",30).setFontAlign(0,0);
  g.drawString(txt, g.getWidth()/2, g.getHeight()/2);
}

On the web page:

Puck.write('myFunction("MESSAGE"­)\n');
