Local Resource Generation

[imhoffd]

It would be nice to investigate a local solution to the resources generation, instead of using the legacy resources server and requiring a login.

• https://www.npmjs.com/package/sharp (requires native code)
• https://www.npmjs.com/package/jimp

Issues this might solve or be solved with this:

• ionic cordova resources asks for credentials to ionic cloud every time #2331 (online generation requires login, offline wouldn't)
• feat: make ionic cordova resources comply with Android O adaptive icons #2132 (Android adaptive icons)
• ionic cordova resources - but for PWA resources #3672 (PWA icons)
• Feature: ionic resources source different images for landscape and portrait #2679 (differentiation between landscape/portrait splashes)
• remove alpha channel to iOS icons #3851 (option to remove alpha channel)
• Ionic Resources not uploading #2924, Ionic Cordova Resources getting stuck #3540, ionic cordova resources fails #3849 (connectivity, streaming issues)

I guess ionic resources was built as an service because image resizing with nodejs will require third party libraries and will add too much overhead to actual framework

And most off libs are not very well suited for cross platform

Long ago when I was working on proxied environment I wrote an small utility on weekends using golang that allows to generate resources offline and is lightweight no dependency an wrapper can be easily wrote around it if we want to ship as npm and can download binaries according to OS.

Maybe worth making and less time consuming if folks at ionic are interested

Edit: Jimp looks more promising

@harshzalavadiya (and others) CLI 4.9.0 just shipped with a hidden option to try a local resources generation tool.

Try this:

npm i -g cordova-res
ionic cordova resources --cordova-res

That's really cool 😎, thanks

Btw, repo link on npm is giving 404 isn't it open source

@harshzalavadiya Thanks, I just had to make it public.

@dwieeb this needs to be the new default :D

@trumbitta Thanks! Glad you like it. I'll be rolling it out to more people as I get more feedback.
