SvelteKit on AWS with SST
Create and deploy a SvelteKit app to AWS with SST.
We are going to create a SvelteKit app, add an S3 Bucket for file uploads, and deploy it to AWS using SST.
Before you get started:
1. Create a project
Let’s start by creating our app.
We are picking the Skeleton project and Yes, using TypeScript syntax options.
Init SST
Now let’s initialize SST in our app. Make sure you have the CLI installed.
This’ll detect that you are in a SvelteKit project and create a sst.config.ts
file in the root.
Start dev mode
Start the dev mode for your SvelteKit app and link it to SST.
2. Add an S3 Bucket
Let’s add a public
S3 Bucket for file uploads. Update your sst.config.ts
.
Link the bucket
Now, link the bucket to our SvelteKit app.
3. Create an upload form
Let’s add a file upload form. Replace your src/routes/+page.svelte
. This will upload a file to a given pre-signed upload URL.
Add some styles.
4. Generate a pre-signed URL
When our route loads, we’ll generate a pre-signed URL for S3 and our form will upload to it. Create a new +page.server.ts
and add the following.
Add the relevant imports.
And install the npm packages.
Head over to the local SvelteKit app in your browser, http://localhost:5173
and try uploading an image. You should see it upload and then download the image.
5. Deploy your app
Now let’s deploy your app to AWS.
Congrats! Your app should now be live!
