How to use Serverless Cloud with SvelteKit

With Serverless Cloud, getting started with SvelteKit is incredibly easy thanks to our templates and built-in adapter.

Creating an App

First, make a new directory for your project and switch to it:

mkdir svelte-demo
cd svelte-demo

Next, start the Cloud Shell with the following command:

npx @serverless/cloud --template sveltekit

Follow the on-screen instructions to log in, and name your app. Soon you’ll find yourself looking at a prompt similar to this:

You’re almost ready, just type “dev” and hit enter:

This will launch the svelte-kit dev server within the Cloud Shell, and you will see output like so:

‍

Now, open http://localhost:3000 in your browser.  Congratulations, you’re running a local dev instance of the SvelteKit starter - but wait, it’s been adapted to use the Cloud SDK!  Open up src/routes/todos/index.js - notice anything different?  The default SvelteKit starter uses a remote API to store data, but with Serverless Cloud, data is right at your fingertips.

Not only that, but it takes only a few lines of code to write event handlers that respond to changes to this data - check out index.js in the project root, and you’ll see a data.on handler. Whenever a todo is modified, that event handler will fire.  Try it from your localhost dev url - add some todos, and you’ll see logs printed in your console almost immediately.

Developer sandboxes are great, but let’s make a preview to share with a friend.  Just type “share”.  This will build and deploy a completely separate instance of your application right in the cloud in under a minute, and print a URL out when done.  You can also deploy to a named stage with the “deploy” command - e.g. “deploy staging”.  Finally, you could run “promote staging production”, which re-uses the build output from the source environment for determinism.

A good next step is to explore the docs to learn more about all the features included with Serverless Cloud - you will experience workflows that offer a level of productivity you’ve never seen before, from fast deployments to quick and easy reseeding of test data, and we’re working hard on adding more features every release.
