"Convert" old app.js files to app.ts (typescript)

[AlexS]

Hello @RalfBecker,
I have the following questions:

1. Should the old app.js code of custom apps work with the new typescript based api in 20.1?
2. What is the best way to convert the old app.js code to app.ts?
3. Why is there still an app.js file in apps with an app.ts file?

I know I have asked something like this before at a phone conversation we had and I think I remember there was a helper script for this, but I can’t find it right now.

Thanks for your patience and your support!

1. Should the old app.js code of custom apps work with the new typescript based api in 20.1?

Yes, thought new stuff like push is not in the javascript base-object, only in the typescript one.
Maybe we backport some, but for sure not everything …

2. What is the best way to convert the old app.js code to app.ts?

There is a script which does most, but not all of the conversation:

EGroupware/egroupware/blob/master/doc/js2ts.php

3. Why is there still an app.js file in apps with an app.ts file?

Because the typescript is compiled to javascript, as browser can only execute javascript.
