Get Script's own name

[Mike Castle]

Silly basic question time.

I've not started a Web App in a while and relearning the basics.

I want to do something like:

function doGet() {
const appName = some_magic_function(...);
return HtmlService.createHtmlOutput('<p>Hello, world!</p>').setTitle(appName);
}

where `appName` ends up being the name of the saved GAS project.

Basically, I rename the project and my web page changes name.

In looking through my old projects, it looks like I simply used a
global variable instead:

const APP_NAME = 'My funky app';

I'm guessing that I would need to do something like
ScriptApp.getScriptId() and look that up via DriveApp?

Or am I, hopefully, missing something basic?

Thanks,
mrc

function doGet() {

  const scriptId = ScriptApp.getScriptId();

  const appName = DriveApp.getFileById(scriptId).getName();

  

  return HtmlService.createHtmlOutput('<p>Hello, world!</p>').setTitle(appName);

}

Just know that making a Drive API call on every page load introduces slight latency. If performance is a priority, caching the project name using CacheService or sticking with a top-level const APP_NAME constant avoids the extra API call and scope requirements.

Pretty much what I thought. I was hoping to avoid that extra call.
