How to dynamically render images in Nuxt3

How do I dynamically render images in Nuxt 3? I want to do something like this:

<img src=`/assets/icons/${imageName}.svg`>

<img src=`/assets/icons/${imageName}.svg`>

But the src property is not working as I had hoped it would. Nuxt is not able to find the image for some reason. Is it because it uses Vite?

/assets/icons translates to public/assets/icons in your workspace. Are you sure that path exists?

So, how should I render the images in the assets folder? I am able to render it like this <img src="~/assets/icons/customers.svg" :alt="item.title" /> But not when I want to render it dynamically

Personally, if the assets do not change (which icons very rarely do) I would suggest moving them to the public directory. It is far more performant to load them from there. Loading assets dynamically is a limitation of vite. That said, you can scan the assets directory at runtime using a composable. For example:

export function useAssetIcon(path: string): string {
  const assets = import.meta.glob('~/assets/icons/*', {
    eager: true,
    import: 'default',
  })
  // @ts-expect-error: wrong type info
  return assets['/assets/icons/' + path]
}

export function useAssetIcon(path: string): string {
  const assets = import.meta.glob('~/assets/icons/*', {
    eager: true,
    import: 'default',
  })
  // @ts-expect-error: wrong type info
  return assets['/assets/icons/' + path]
}

And use it as such:

const imageSrc = useAssetIcon(imageName)

const imageSrc = useAssetIcon(imageName)
