adapter-vercel

A SvelteKit adapter that creates a Vercel app.

If you're using adapter-auto, you don't need to install this unless you need to specify Vercel-specific options, since it's already included.

Usage

The edge and split options depend on the Vercel Build Output API which is currently in beta. For now, you must opt in by visiting https://vercel.com/[YOUR_USERNAME]/[YOUR_PROJECT]/settings/environment-variables and adding ENABLE_VC_BUILD with the value 1.

Add "@sveltejs/adapter-vercel": "next" to the devDependencies in your package.json and run npm install.

Then in your svelte.config.js:

import vercel from '@sveltejs/adapter-vercel';

export default {
  kit: {
    // default options are shown
    adapter: vercel({
      // if true, will deploy the app using edge functions
      // (https://vercel.com/docs/concepts/functions/edge-functions)
      // rather than serverless functions
      edge: false,

      // an array of dependencies that esbuild should treat
      // as external when bundling functions
      external: [],

      // if true, will split your app into multiple functions
      // instead of creating a single one for the entire app
      split: false
    })
  }
};

Notes

Vercel functions contained in the /api directory at the project's root will not be included in the deployment — these should be implemented as endpoints in your SvelteKit app.
