Migrate SvelteKit from Heroku to EasyHost

Move your SvelteKit app in four steps, and keep Heroku running until the new deployment works.

Last updated November 9, 2026

Export your variables

heroku config -s > .env

Then import them into EasyHost.

npx ezhst env import .env

Change the SvelteKit setup

Replace @sveltejs/adapter-vercel, adapter-netlify or adapter-auto with @sveltejs/adapter-node.

Procfile is not read by EasyHost, so its build and routing rules need moving into your app or into build settings.

Install @sveltejs/adapter-node and set it in svelte.config.js. The auto adapter is not enough.

Deploy and test

npx ezhst projects create my-project --link
npx ezhst apps create my-app
npx ezhst link --project <project-slug> --app <app-slug>
npm i -D @sveltejs/adapter-node
npx ezhst build set --start "node build"
npx ezhst env import .env
npx ezhst deploy

Test your easyhost.fun URL before changing DNS. Heroku runs your app on dynos, so check anything that depends on it, such as platform functions or cron configuration. Schedules move to EasyHost schedules.

Switch your domain

npx ezhst domains add www.example.com
npx ezhst domains list
npx ezhst domains verify www.example.com

Follow the custom domain guides for your DNS provider. Keep Heroku running until traffic has moved. Also read why SvelteKit may be unreachable and the Heroku overview.
