      const imageRef = FirebaseClient.storage().ref('images').child('image_001')

      fs.readFile(uploadUri, 'base64')
        .then((data) => {
          return Blob.build(data, { type: `${mime};BASE64` })
        })
        .then((blob) => {
          uploadBlob = blob
          return imageRef.put(blob, { contentType: mime })
        })
        .then(() => {
          uploadBlob.close()
          return imageRef.getDownloadURL()
        })
        .then((url) => {
          resolve(url)
        })
        .catch((error) => {
          reject(error)
      })
    })
  }
