Deploy a Svelte site

Svelte is an increasingly popular, open-source framework for building user interfaces and web applications. Unlike most frameworks, Svelte is primarily a compiler that converts your component code into efficient JavaScript that surgically updates the DOM when your application state changes.

In this guide, you will create a new Svelte application and deploy it using Cloudflare Pages. You will use SvelteKit, the official Svelte framework for building web applications of all sizes.

Setting up a new project

Create a new project by running the npm init command in your terminal, giving it a title:

$ npm init [email protected] my-svelte-app
$ cd my-svelte-app

During init, SvelteKit will prompt you for customization choices. Your answers will not affect the rest of this tutorial. Choose the option that is ideal for your project.

Before you continue

All of the framework guides assume you already have a fundamental understanding of git. If you are new to git, refer to this summarized git handbook on how to set up git on your local machine.

If you clone with SSH, you must generate SSH keys on each computer you use to push or pull from GitHub.

Creating a GitHub repository

Create a new GitHub repository by visiting After creating a new repository, prepare and push your local application to GitHub by running the following commands in your terminal:

# Setup the local repository
$ git init
$ git remote add origin<username>/<repo>
$ git branch -M main
# Commit all initial files
$ git add -A
$ git commit -m "initial commit"
# Send commit to new GitHub repo
$ git push -u origin main

Deploying with Cloudflare Pages

Deploy your site to Pages by logging in to the Cloudflare dashboard > Account Home > Pages and selecting Create a project.

You will be asked to authorize access to your GitHub account if you have not already done so. Cloudflare needs this so that it can monitor and deploy your projects from the source. You may narrow access to specific repositories if you prefer; however, you will have to manually update this list within your GitHub settings when you want to add more repositories to Cloudflare Pages.

Select the new GitHub repository that you created and, in the Set up builds and deployments section, provide the following information:

Configuration optionValue
Production branchmain
Build commandnpm run build
Build directorybuild
Environment VariablesNODE_VERSION: 14

Optionally, you can customize the Project name field. It defaults to the GitHub repository’s name, but it does not need to match. The Project name value is assigned as your * subdomain.

SvelteKit Configuration

By default, SvelteKit prepares our project with the assumption that it will deployed to a Node.js server. This is not appropriate for this tutorial, but luckily SvelteKit is flexible and has a ready-made “adapter” for your needs. A few, easy changes have to be made.

First, install the @sveltejs/adapter-static package:

$ npm install @sveltejs/[email protected] --save-dev

Then, in the svelte.config.js file, update the adapter selection:

++ import adapter from '@sveltejs/adapter-static';
/** @type {import('@sveltejs/kit').Config} */
const config = {
kit: {
++ adapter: adapter(),
// ... truncated ...
export default config;

Finalize Setup

After completing configuration, click the Save and Deploy button.

You will see your first deploy pipeline in progress. Pages installs all dependencies and builds the project as specified.

Cloudflare Pages will automatically rebuild your project and deploy it on every new pushed commit.

Additionally, you will have access to preview deployments , which repeat the build-and-deploy process for pull requests. With these, you can preview changes to your project with a real URL before deploying them to production.
