Bucketeer persigned links?

Question

I currently use AWS s3's createPresignedPost service to get a url from my server that I can then upload files to directly to from my web app (rather than sending the file to my server).

I am currently looking at moving to Heroku and wondering if Bucketeer will offer me the same options?

const params = {
    Bucket: `${config.clusterName}-${config.projectName}-s3`,
    Expires: 3600,
    Fields: { key: `uploads/${filename}` },
    Conditions: [
      ['content-length-range', 0, 10000000], // 10 Mb
    ],
  }

  console.log("calling createPresignedPost")

  S3.createPresignedPost(params, (e, data) => {
    if (e) return reject(e)
    ret = {
      hostedUrl,
      url: data.url,
      fields: {
        key: data.fields.key,
        bucket: data.fields.bucket,
        algorithm: data.fields['X-Amz-Algorithm'],
        credential: data.fields['X-Amz-Credential'],
        date: data.fields['X-Amz-Date'],
        policy: data.fields.Policy,
        signature: data.fields['X-Amz-Signature'],
      },
    }
    resolve(ret)
  })
