Bolt.new AI and Wasabi integration: Step-by-Step Guide 2025

To integrate Bolt.new with Wasabi, you don’t “connect Bolt directly to Wasabi.” Instead, you write normal backend code inside Bolt.new’s server environment and use the Wasabi S3‑compatible API (which is the same API surface as AWS S3). That means you can use any standard AWS S3 SDK, point it at Wasabi’s endpoint, load your Wasabi keys through environment variables, and perform uploads/downloads exactly like you would with S3. Bolt.new just executes your code; the integration happens through HTTP calls to Wasabi’s REST API.

 

What Integration Really Means Here

 

You wire a backend module inside Bolt.new that talks to Wasabi’s S3‑compatible REST endpoints using your Wasabi access key + secret key. You store those keys in Bolt.new environment variables, not in your code. Then you use an AWS S3 SDK (JavaScript, Python, Go—whatever backend runtime you’re using inside Bolt.new) and override the endpoint so that the SDK sends all S3 API calls to Wasabi instead of AWS.

 

• Wasabi is fully S3-compatible → same API calls.
• Bolt.new backend = normal Node/Python/Go runtime → you install any SDK using package manager.
• Authentication uses access key + secret key → stored as environment variables.
• All data flows over HTTPS → direct bolt→Wasabi REST requests; no hidden magic.

 

How to Implement It (Node.js example, which Bolt.new supports cleanly)

 

In Bolt.new, create a backend file (like server.js or an API route). Install AWS SDK v3:

 

npm install @aws-sdk/client-s3

 

Then configure the client to use Wasabi’s endpoint:

// server/wasabiClient.js

import { S3Client, PutObjectCommand } from "@aws-sdk/client-s3";

const wasabi = new S3Client({
  region: "us-east-1", // use your chosen region
  endpoint: "https://s3.us-east-1.wasabisys.com", // Wasabi S3 endpoint
  credentials: {
    accessKeyId: process.env.WASABI_ACCESS_KEY,     // set these in Bolt.new env panel
    secretAccessKey: process.env.WASABI_SECRET_KEY
  },
  forcePathStyle: true // Wasabi recommends enabling this for best compatibility
});

export async function uploadToWasabi(bucket, key, data) {
  // data can be Buffer, string, or stream
  const command = new PutObjectCommand({
    Bucket: bucket,
    Key: key,
    Body: data
  });

  return await wasabi.send(command);
}

 

Now you can call this from any API route:

// server/routes/upload.js

import { uploadToWasabi } from "../wasabiClient.js";

export default async function handler(req, res) {
  try {
    const fileContent = "Hello Wasabi!"; // in reality, take from req.files or req.body
    await uploadToWasabi("my-bucket", "test.txt", fileContent);

    res.json({ ok: true });
  } catch (err) {
    res.status(500).json({ error: err.message });
  }
}

 

Environment Variables in Bolt.new

 

In the Bolt.new UI, open the Environment panel and create:

• WASABI_ACCESS_KEY
• WASABI_SECRET_KEY

Never hard‑code keys in your JS files.

 

Important Notes for a Real Integration

 

• Region matters. Wasabi endpoints are region-specific (e.g., s3.us-east-1.wasabisys.com, s3.eu-central-1.wasabisys.com). Use the right one for your bucket.
• Permissions. Ensure your Wasabi user has permission for ListBucket, PutObject, GetObject, DeleteObject.
• Bolt.new sandbox. It allows outbound HTTPS calls, so S3-style API calls to Wasabi work normally.
• Uploads from browser. For larger files, use signed URLs generated by your backend, so the browser uploads directly to Wasabi without routing the file through your server.

 

Minimal Signed URL Example (optional but real)

 

// server/routes/signedUrl.js

import { S3Client, PutObjectCommand, getSignedUrl } from "@aws-sdk/s3-request-presigner";

const client = new S3Client({
  region: "us-east-1",
  endpoint: "https://s3.us-east-1.wasabisys.com",
  credentials: {
    accessKeyId: process.env.WASABI_ACCESS_KEY,
    secretAccessKey: process.env.WASABI_SECRET_KEY
  },
  forcePathStyle: true
});

export default async function handler(req, res) {
  const command = new PutObjectCommand({
    Bucket: "my-bucket",
    Key: "upload-target.txt"
  });

  const url = await getSignedUrl(client, command, { expiresIn: 300 }); // 5 minutes
  res.json({ url });
}

 

This lets your frontend POST the file directly to Wasabi, reducing load on your Bolt backend.

 

Summary

 

Integrating Bolt.new with Wasabi means using normal backend code plus S3 API calls. Use the AWS SDK, point the endpoint to Wasabi, store keys in environment variables, and call Wasabi through HTTPS. That’s it—no special Bolt integration layer, just clean standard API wiring.
