Does NestJS Work With Cloudflare R2?

import { Injectable } from '@nestjs/common';
import { S3Client, PutObjectCommand, GetObjectCommand } from '@aws-sdk/client-s3';

@Injectable()
export class R2Service {
  private s3Client: S3Client;

  constructor() {
    this.s3Client = new S3Client({
      region: 'auto',
      endpoint: `https://${process.env.R2_ACCOUNT_ID}.r2.cloudflarestorage.com`,
      credentials: {
        accessKeyId: process.env.R2_ACCESS_KEY_ID,
        secretAccessKey: process.env.R2_SECRET_ACCESS_KEY,
      },
    });
  }

  async uploadFile(bucketName: string, key: string, body: Buffer): Promise<void> {
    await this.s3Client.send(
      new PutObjectCommand({ Bucket: bucketName, Key: key, Body: body })
    );
  }

  async getFile(bucketName: string, key: string): Promise<Buffer> {
    const result = await this.s3Client.send(
      new GetObjectCommand({ Bucket: bucketName, Key: key })
    );
    return result.Body?.transformToByteArray() || Buffer.alloc(0);
  }
}
