Hi Paolo,

I can confirm that the files: LScommons.js, LSpushpage.js, and misc.js are not distributed since the new JavaScript Client library does not need them anymore (only the lightstreamer.js is needed).
And so you should pick them up from your original project.

Please also note that the proper folder where to copy the files depends upon how the script inclusion is declared in your HTML; referring to your original page:

HTML Code:
  <script language="JavaScript" src="LS/lscommons.js"></script>
  <script language="JavaScript" src="LS/lspushpage.js"></script>
  
  <script src="../commons/custom/misc.js" type="text/javascript"></script>

The files lscommons and lspushpage are expected in a subfolder LS while the misc file in the relative path "../commons/custom/".

Regards,
Giuseppe
