Allow separate icon settings for maskable

[rotsee]

Almost always you want to have two different variants of your logo in your manifest: Maskable, and regular icons (see e.g. https://web.dev/maskable-icon/). In fact, Google Chrome will even warn developers when using the same version. The side effects of not providing separate icons are that icons will look weird somewhere; On iOS, on Android, when adding a desktop shortcut to Gnome, etc, etc.

It would be truly great if the icon module could handle this for us! E.g. by allowing something like this in the options:

	icon: {
	      icons: [{
	        "src": "/assets/icon-maskable.png",
	        "purpose": "maskable",
	      }, {
	        "src": "/assets/icon.png",
	        "purpose": "any",
		  }:],
	}

...while still generating all the sizes etc.

This is related to the following:

• https://github.com/nuxt-community/pwa-module/issues/392 (but this affects not only iOS, and the workaround mentioned does not solve all of the issues on all platforms where it arises)
• https://github.com/nuxt-community/pwa-module/issues/316 (again, a workaround only targeting iOS)
• https://github.com/nuxt-community/pwa-module/issues/259 (where maskable was added to all icons)

Hi. Do you have any news about this issue?

[joerees]

It would be good if we can add multiple icon settings, as mentioned above to add maskable to specific sizes, not all.

Will there be a fix for this issue ?

Purpose "maskable any" is actually discouraged and rejected by tools like www.pwabuilder.com, so being able to define icons separately is crucial.

Here is my solution for this, you have to create your own manifest.json in "static" folder and change your manifest URL instead of nuxt generated.

static/manifest.json static/pwa/any/icon-512x512.png static/pwa/maskable/icon-512x512.png

~ /static/manifest.json

{
    "name": "My App,
    "short_name": "My App",
    "description": "My Description,
    "icons": [
      {
        "src": "/pwa/any/icon-512x512.png",
        "sizes": "512x512",
        "type": "image/png",
        "purpose": "any"
      },
      {
        "src": "/pwa/maskable/icon-512x512.png",
        "sizes": "512x512",
        "type": "image/png",
        "purpose": "maskable"
      }
    ],
    "start_url": "/?standalone=true",
    "display": "standalone",
    "background_color": "#ffffff",
    "theme_color": "#1a73e8",
    "lang": "en"
  }

and modify nuxt.config.js under "head" option.

~ nuxt.config.js

export default {
  head: {
    link: [
      {
        hid: 'manifest',
        rel: 'manifest',
        'data-n-head': 'ssr',
        href: '/manifest.json'
      }
    ]
  }
}

Here you can also visit your manifest.json https://myapp.com/manifest.json

I tried this in www.pwabuilder.com and it works.

Also you can generate maskable icon here https://maskable.app/editor

I've done it using a PWA config similar to the one below:

{
    pwa: {
        manifest: {
            icons: [
                // we want to define 'any' icon type manually, because icon module will create icons with type 'maskable'
                ...["64x64", "120x120", "144x144", "152x152", "192x192", "384x384", "512x512"].map(size => ({
                    src: `/icons/any/${size}.png`,
                    sizes: size,
                    type: "image/png",
                    purpose: "any"
                }))
            ],
        },
        icon: {
            fileName: "icon_maskable.png",
            purpose: ["maskable"],
        }
    }
}

Though, you'd have to manually create all icon variants. There's most certainly a way to automate it, but I couldn't be bothered. You could also disable the module's icon generation all together and add another of those mappings for the maskable type.

I already tried that but it is still combining the "purpose" with "any maskable".

[Migushthe2nd]

It works for me as the are only 'any' and 'maskable' separately
