Configure the config file :

import { S3Uploader } from '@bubojs/uploader';

export const s3Bucket = new S3({
  endpoint: process.env.S3_ENDPOINT,
  credentials: {
    accessKeyId: process.env.S3_ACCESS_KEY_ID,
    secretAccessKey: process.env.S3_SECRET_ACCESS_KEY,
  },
  region: process.env.S3_REGION,
});

export const uploader = new S3Uploader({
  bucket: s3Bucket,
  bucketName: process.env.S3_BUCKET_NAME,
  folderName: process.env.S3_FOLDER_NAME,
});

Then use the object uploader functions as a middleware of your routes :

import { uploader } from './config'
import { Controller, BeforeMiddleware, Post } from '@bubojs/api'

@Controller()
class TestController {

  /**
   * upload route with form-data body
   * Body: {
   *  file: 📄
   * }
   */
  @BeforeMiddleware(
    uploader.buildUploadEndpoint({ authorizedExtensions: ['jpeg', 'png']})
  )
  @Post('/')
  async uploadRoute() {
    console.log('uploaded files')
    return {}
  }

  /**
   * download route
   * Params: {
   *  key: 'filename.jpeg'
   * }
   */
  @Get(':key', { bodyFormat: BodyFormat.AUTO, rawHandler: true })
  downloadRoute() {
    return uploader.buildDownloadEndpoint({
      retrieveKeyCallback: async (req: any) => {
        return req.params.key;
      },
    });
  }

  /**
   * download route
   * Params: {
   *  key: 'filename.jpeg'
   * }
   */
  @Delete(':key', { rawHandler: true })
  deleteRoute() {
    return uploader.buildDeleteEndpoint({
      retrieveKeyCallback: async (req: any) => {
        return req.params.key;
      },
    });
  }
