Is there a way to generate only two (portrait and landscape) apple splash screen images?

Is your feature request related to a problem? Please describe. Too many files are generated. They are huge, clutter, and require more network requests for the user, more time to build, etc, and seem generally unnecessary when you could have one high res image per screen orientation.

Describe the solution you’d like A CLI flag to only generate one specific portrait/landscape resolution for apple

Describe alternatives you’ve considered Doing this manually

Additional context I have no idea why apples requires a 2048x2732 image, when all other companies and devices (google, microsoft) are good with a 512 image and a color… But regardless of the reason, having this one image should suffice. The generator makes 2 manifest icons and 25 (!) apple startup images… I mean the HTML alone is over 5kb… It’s just too much for a lightweight PWA; I’d rather at least have the option (default to how it currently works) to only generate a few splash files. Currently, it runs forever, then generates a bunch of files I don’t need, I have to delete them all, and remove the links from my html page(s). Or, the user is stuck with a dozen more files than they need, a bunch more network requests, and my app takes longer to load and to install, more data is used hosting, etc.

Can I link to multiple html files?

When running npx, will it remove chromium once it’s done? If I’m only running it once, I wouldn’t want all of chromium sitting on my hard drive for each project I run this on…

No, you can’t link to multiple HTML files. You need to run the command multiple times or manually duplicate.

npx commands cache the dependencies under your configured npm cache folder, see https://docs.npmjs.com/cli/v7/configuring-npm/folders#cache. npm clears the cache with it’s internal logic.

If you worry about your disk storage, you can download pwa-asset-generator globally, with npm i -g pwa-asset-generator command and you’ll still be able to execute it on any project you might have.

If you have any chromium based browser installed on your system, pwa-asset-generator won’t install the browser anyway, but will use your system browser instead.

Also, is there a way to generate transparent icons but opaque splash screen images?

Thanks in advance for listening to my input : )

You need to execute two commands, one for splash images another for icons only. Please see the relevant section on FAQ in docs - https://github.com/onderceylan/pwa-asset-generator#how-can-i-generate-a-transparent-favicon-and-app-icons-with-opaque-background.
