Nuxt on AWS with SST

Create and deploy a Nuxt app to AWS with SST.

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

Before you get started, make sure to configure your AWS credentials.

1. Create a project

Let’s start by creating our project.

Terminal window
npx nuxi@latest init my-nuxt-app
cd my-nuxt-app

We are picking the npm as the package manager.

Init SST

Now let’s initialize SST in our app.

Terminal window
npx sst@latest init
npm install

Select the defaults and pick AWS. This’ll create a sst.config.ts file in your project root.

It’ll also ask you to update your nuxt.config.ts with something like this.

nuxt.config.ts
export default defineNuxtConfig({
  compatibilityDate: '2024-04-03',
  nitro: {
    preset: 'aws-lambda'
  },
  devtools: { enabled: true }
})

Start dev mode

Run the following to start dev mode. This’ll start SST and your Nuxt app.

Terminal window
npx sst dev

Once complete, click on MyWeb in the sidebar and open your Nuxt app in your browser.

2. Add an S3 Bucket

Let’s allow public access to our S3 Bucket for file uploads. Update your sst.config.ts.

sst.config.ts
const bucket = new sst.aws.Bucket("MyBucket", {
  access: "public"
});

Add this above the Nuxt component.

Now, link the bucket to our Nuxt app.

sst.config.ts
new sst.aws.Nuxt("MyWeb", {
  link: [bucket],
});

3. Generate a pre-signed URL

When our app loads, we’ll call an API that’ll generate a pre-signed URL for the file upload. Create a new server/api/presigned.ts with the following.

server/api/presigned.ts
export default defineEventHandler(async () => {
  const command = new PutObjectCommand({
    Key: crypto.randomUUID(),
    Bucket: Resource.MyBucket.name,
  });


  return await getSignedUrl(new S3Client({}), command);
})

Add the relevant imports.

src/app.tsx
import { Resource } from "sst";
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 @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 our app.vue with:

app.vue
<script setup>
  const file = ref(null);
  const { data } = await useFetch('/api/presigned');


  async function onSubmit() {
    const upload = file.value.files[0];
    const image = await fetch(data.value, {
      body: upload,
      method: "PUT",
      headers: {
        "Content-Type": upload.type,
        "Content-Disposition": `attachment; filename="${upload.name}"`,
      },
    });


    window.location.href = image.url.split("?")[0];
  }
</script>
<template>
  <form novalidate @submit.prevent="onSubmit">
    <input type="file" ref="file" accept="image/png, image/jpeg" />
    <button type="submit">Upload</button>
  </form>
</template>

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
npx sst deploy --stage production

You can use any stage name here but it’s good to create a new stage for production.

Congrats! Your site should now be live!

SST Nuxt app

Connect the console

As a next step, you can setup the SST Console to git push to deploy your app and monitor it for any issues.

SST Console Autodeploy

You can create a free account and connect it to your AWS account.
