function offset(count, offset, limit) {
  const finalOffset = Math.max(Math.min(count, offset), 0);
  const remainedCount = Math.min(count, count - finalOffset);
  const finalCount = (typeof limit === 'number') ? Math.min(limit, remainedCount) : remainedCount;
  return { offset: finalOffset, finalCount: finalCount };
}

console.log(offset(10, 0)); // {"offset":0,"finalCount":10}
console.log(offset(10, 4)); // {"offset":4,"finalCount":6}
console.log(offset(10, 10)); // {"offset":10,"finalCount":0}

After migrating from heroku to dokku, we had to also chance codeship so we deploy to dokku. I followed the following steps to successfully deploy to dokku.

1. Save the public key of the codeship project. It is found in Project Settings > General Settings.
2. Copy the public key to a file /tmp/codeship_projectname.pub.
3. Make sure when pasting, all the contents are in a single line and not multiple lines.
4. Add the public key to dokku using the following command in console. Reference.

cat /tmp/codeship_projectname.pub | ssh root@yourdokkuinstance "sudo sshcommand acl-add dokku [description]"
