NAPA supporting ECMAScript 2015 or Typescript for both on- and off-premise programming of event receivers
Present programming of Remote Event Receivers is complicated and limited so farm deployed server-side Event receivers are used. Support of ECMAScript 2015 or Typescript is needed in a simple freestanding tool (NAPA?) for both on- and off-premise installations.
Thanks for your feedback! Although we appreciate your time and effort to give us this feedback, it’s not something we’re planning to do right now. NAPA service is no longer supported and the models are moving more towards scenarios with web hooks and Azure functions.
