Deploy a SvelteKit App

This tutorial walks you through deploying a SvelteKit application on Temps. SvelteKit supports static, server-rendered, and hybrid output — all work on Temps.

What you will build

A SvelteKit app deployed from a Git repository
SSR with the Node adapter or static prerendering
Automatic HTTPS and deployment on every push

Time required: 10 minutes.

Prerequisites:

A running Temps instance (install guide)
A SvelteKit app in a Git repository
(Optional) A custom domain

Step 1: Prepare your app

Install the Node adapter

For SSR deployments, use the Node adapter:

npm install -D @sveltejs/adapter-node

Update your svelte.config.js:

svelte.config.js

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

export default {
  kit: {
    adapter: adapter()
  }
};

For static sites, use @sveltejs/adapter-static instead.

Verify your package.json

package.json

{
  "scripts": {
    "dev": "vite dev",
    "build": "vite build",
    "preview": "vite preview"
  },
  "devDependencies": {
    "@sveltejs/adapter-node": "^5.0",
    "@sveltejs/kit": "^2.0",
    "svelte": "^5.0",
    "vite": "^6.0"
  }
}

Add a health check

src/routes/health/+server.js

import { json } from '@sveltejs/kit';

export function GET() {
  return json({ status: 'ok' });
}

Step 2: Create a project

Open the Temps dashboard
Click New Project
Connect your repository
Temps detects SvelteKit automatically

Or via CLI:

bunx @temps-sdk/cli projects create -n "my-svelte-app" -d "SvelteKit application"
bunx @temps-sdk/cli projects git -p my-svelte-app --owner yourorg --repo my-svelte-app --branch main -y

Step 3: Create a Dockerfile (optional)

Temps auto-detects SvelteKit, but you can customize:

Dockerfile

FROM node:22-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

FROM node:22-alpine
WORKDIR /app
ENV NODE_ENV=production
COPY --from=builder /app/build ./build
COPY --from=builder /app/package.json .
EXPOSE 3000
CMD ["node", "build"]

Step 4: Deploy

Push to your connected branch, or deploy manually:

bunx @temps-sdk/cli deploy my-svelte-app -b main -e production -y

Environment variables

SvelteKit uses PUBLIC_ prefixed variables for client-side access:

# Server-only (available in +server.js, +page.server.js, hooks)
DATABASE_URL=postgres://user:pass@host:5432/db
API_SECRET=your-secret

# Available in client-side code
PUBLIC_API_URL=https://api.example.com

PUBLIC_ variables are embedded at build time. Redeploy after changing them. Server-only variables are available at runtime.

What to do next

Add a custom domain — point your domain to this deployment
Set up preview deployments — get a preview URL for every pull request
Add monitoring — uptime checks and alerts
