SolidStart on AWS with SST

Create and deploy a SolidStart app to AWS with SST.

We are going to create a SolidStart app, add an S3 Bucket for file uploads, and deploy it to AWS using SST.

Before you get started:

  1. Configure your AWS credentials
  2. Install the SST CLI

1. Create a project

Let’s start by creating our project.

Terminal window
npm init solid@latest my-solid-app
cd my-solid-app
npm install

We are picking the bare, and TypeScript options.

Init SST

Now let’s initialize SST in our app. Make sure you have the CLI installed.

Terminal window
sst init

This’ll detect that you are in a SolidStart project and create a sst.config.ts file in the root.

Start dev mode

Start the dev mode for your SolidStart app and link it to SST.

Terminal window
npm run dev

2. Add an S3 Bucket

Let’s add a public S3 Bucket for file uploads. Update your sst.config.ts.

const bucket = new"MyBucket", {
public: true

Now, link the bucket to our SolidStart app.

new"MyWeb", {
link: [bucket],

3. Generate a pre-signed URL

When our app loads, we’ll generate a pre-signed URL for the file upload and use it in our form. Add this below the imports in src/app.tsx.

async function presignedUrl() {
"use server";
const command = new PutObjectCommand({
Key: crypto.randomUUID(),
return await getSignedUrl(new S3Client({}), command);
export const route = {
load: () => presignedUrl(),

Add the relevant imports.

import { Resource } from "sst";
import { createAsync } from "@solidjs/router";
import { getSignedUrl } from "@aws-sdk/s3-request-presigner";
import { S3Client, PutObjectCommand } from "@aws-sdk/client-s3";

And install the npm packages.

Terminal window
npm install @solidjs/router @aws-sdk/client-s3 @aws-sdk/s3-request-presigner

4. Create an upload form

Add a form to upload files to the presigned URL. Replace the App() component in src/app.tsx with:

export default function App() {
const url = createAsync(() => presignedUrl());
return (
<h1>Hello world!</h1>
onSubmit={async (e) => {
const file = ( as HTMLFormElement).file.files?.[0]!;
const image = await fetch(url() as string, {
body: file,
method: "PUT",
headers: {
"Content-Type": file.type,
"Content-Disposition": `attachment; filename="${}"`,
window.location.href = image.url.split("?")[0];
<input name="file" type="file" accept="image/png, image/jpeg" />
<button type="submit">Upload</button>

Head over to the local app in your browser, http://localhost:3000 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.

Terminal window
sst deploy

Congrats! Your site should now be live!
