Vercel is extending its newly introduced approach to working with feature flags to SvelteKit, with the v2.6.0 release of @vercel/flags.

With @vercel/flags/sveltekit you can now implement feature flags in your SvelteKit application code and call them within functions. Using this pattern automatically respects overrides set by the Vercel Toolbar, and integrates with our Developer Experience Platform features like Web Analytics and Runtime Logs.

import { flag } from '@vercel/flags/sveltekit'
export const showDashboard = flag<boolean>({
  key: 'dashboard',
  async decide () {
    // your feature flag logic
    return true
  }
})
