Zero-config deployments

When you create a new SvelteKit project with npm create svelte@latest, it installs adapter-auto by default. This adapter automatically installs and uses the correct adapter for supported environments when you deploy:

• @sveltejs/adapter-cloudflare for Cloudflare Pages
• @sveltejs/adapter-netlify for Netlify
• @sveltejs/adapter-vercel for Vercel
• svelte-adapter-azure-swa for Azure Static Web Apps

It's recommended to install the appropriate adapter to your devDependencies once you've settled on a target environment, since this will add the adapter to your lockfile and slightly improve install times on CI.

Environment-specific configuration permalink

To add configuration options, such as { edge: true } in adapter-vercel and adapter-netlify, you must install the underlying adapter — adapter-auto does not take any options.

Adding community adapters permalink

You can add zero-config support for additional adapters by editing adapters.js and opening a pull request.
