openlayers, how to get all modified features together from vector source

  1. I am trying to Edit and save features in openlayers. While doing so, I got stuck at one place where I want to get all modified features together from vector source. Is there any solution?

  2. Also suggest how can I implement feature audit functionality using openlayers, geoserver, postgis. Any solution available?

You have to listen to addfeature removefeature and changefeature events to get informed and store feature modifications.

source.on ('changefeature', (e) => {
  // e.feature has changed
  // do something with it...
  e.feature._state = 'update';
});

Look at WFS-T and functions as writeTransaction to send modifications to server (https://openlayers.org/en/latest/apidoc/module-ol_format_WFS-WFS.html).
