Internal server error: Can't find variable: require

[bene]

What version of HonoX are you using?

0.1.23

What steps can reproduce the bug?

I want do create an upload route which uses the @aws-sdk/client-s3 package. However when I use it as I do normally the error below gets thrown. I tried the minio package which also didn't work. I guess it's a common issue with packages?

1. Start new HonoX project: bun create hono@latest
2. Install S3 client: bun add @aws-sdk/client-s3
3. Create

// app/routes/api/upload.ts
import { PutObjectCommand, S3Client } from "@aws-sdk/client-s3";
import { Hono } from "hono";

const app = new Hono();

const s3 = new S3Client({
  region: process.env.S3_REGION as string,
  forcePathStyle: true,
  endpoint: process.env.S3_URL as string,
  credentials: {
    accessKeyId: process.env.S3_ACCESS_KEY_ID as string,
    secretAccessKey: process.env.S3_ACCESS_KEY_SECRET as string,
  },
});

app.post("/", (c) => {
  // Use s3 client
});

export default app;

What is the expected behavior?

Be able to use S3 client without issues.

What do you see instead?

Hi @bene

I think It's a Vite issue. I've investigated for a while, but I could not find a good solution. It may not support that library.

I ran into the same problem myself, but I put import require from "node:require" on the code which throw error (but not good idea)

The same issue happened when I tried to use the mysql2 driver.
