Specify Vite mode in svelte-kit build

[edenworky]

Describe the problem

I want to be able to set build mode. In Vite you can do vite build --mode some-mode, but this can currently only be set in svelte.config.js.

Describe the proposed solution

Support svelte-kit build --mode some-mode

Alternatives considered

Have a separate svelte.config.js just for the tests, but I can't find a way to point svelte-kit build to it

Importance

i cannot use SvelteKit without it

Additional Information

This makes testing very difficult since there's no simple way to detect that the app is running in test env

Alternatively, you can use an environmental variable like VITE_MODE=some-mode svelte-kit build(or cross-env VITE_MODE=some-mode svelte-kit build to cover windows). And use it in svelte.config.js:

export default {
  kit: {
    vite: {
      mode: process.env.VITE_MODE
    }
  }
}
