# Deploy a SvelteKit app that uses npm

EasyHost picks npm when it finds `package-lock.json`. There is nothing to configure, and these are the exact commands it runs for SvelteKit.

## What EasyHost runs

| Step | Command |
| --- | --- |
| Lockfile | `package-lock.json` |
| Install | `npm ci` |
| Build | `vite build`, through your package build script |
| Start | `node build`, set as the start command or as `scripts.start` |

Scripts run with `npm run <script>`. Dev dependencies are available during the build, and the app runs with `NODE_ENV=production`.

## Deploy

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

```
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
```

## Things to watch with npm

`npm ci` fails if the lockfile and `package.json` disagree. Run `npm install` locally and deploy again. npm 11 lockfiles need Node 24.

Commit `package-lock.json`. Without any lockfile, EasyHost falls back to `npm install`. To replace the install step, run `ezhst build set --install "<command>"`.

## Frequently asked questions

### How do I change the npm install command?

Run `ezhst build set --install "<command>"`, then `ezhst redeploy`. Pass an empty string to return to auto-detection.
