[nuxt3][vercel] Feature request: Support vercel provider for static app (nuxt generate)

[hartmut-co-uk]

Feature

Feature request: Support (nuxt3) nuxt/image with vercel provider for static app -> nuxt generate.

Expected

Vercel config is generated and contains the "images" property which configures the Image Optimization feature.

Actual

Website is generated, <nuxt-image> components are processed fine, but vercel config does not contain the "images" property.

Reproduction example

@hartmut-co-uk This may be happening because static image generation is not supported yet (4th checkbox):
#548

Many thanks for the ref @mrdannyjohnson!

I'd guess this work item would mean image variants (srcset) are actually generated + packaged at pre-render ('generate') time using e.x. IPX?

Basically I might even prefer this option - but as far as this issue is concerned the Vercel Image Optimization(https://vercel.com/docs/concepts/image-optimization) should be used.
Basically the website is static, pre-rendered - but using vercel images, like when running on nitro, SSR..

Example

1. nuxt3 default using nuxt build, nitro, SSR via vercel edge function
   -> https://nuxt3-generate-static-vercel-image-lb046wh8w-info301.vercel.app/)
2. vs. result of nuxt generate
   -> https://nuxt3-generate-static-vercel-image-7scsed04t-info301.vercel.app/

Have you tried setting provider: 'vercel' in your image config?

[hartmut-co-uk]

hah! And I thought something from this reproduction example was different from my actual project...

I've created following branch to show the state with provider: 'vercel': image-provider-vercel
=> vercel deployed as https://nuxt3-generate-static-vercel-image-lxienje6o-info301.vercel.app/

PS: Further I have changed the vercel project settings, see screenshot in branch README.. now using 'yarn generate' and default output directory. (this shouldn't make any difference though)

The generated image src/srcset now show correct use of vercel path... but what's missing as stated in initial post seems to be

Vercel config is generated and contains the "images" property

any pointers which repo/package this actually would need to be solved with?

• https://github.com/nuxt/framework ?
• https://github.com/unjs/nitro ?

[hartmut-co-uk]

The page in question has only a hand full of routes, as some sort of workaround, I was able to solve what I was trying to achieve by simply configuring all my routes for prerender:

    nitro: {
        prerender: {
            routes: ['/', '/a', '/b', '/c']
        }
    },

It's deployed to vercel and not served via nitro functions but static as expected. Vercel image provider is still getting configured and working.

ℹ️ I'll keep the issue open, since I think it would still be good to have vercel image provider working with nuxt generate.

Closing as the fix was introduced in a linked PR.

Feel free to reopen if needed :)
