If you use the predefined access control lists value of 'publicRead', you can upload the file and access it with a very simple url structure:

// Upload to GCS
const opts: UploadOptions = {
  gzip: true,
  destination: dest, // 'someFolder/image.jpg'
  predefinedAcl: 'publicRead',
  public: true
};
return bucket.upload(imagePath, opts);

You can then construct the url like so:

const storageRoot = 'https://storage.googleapis.com/';
const bucketName = 'myapp.appspot.com/'; // CHANGE TO YOUR BUCKET NAME
const downloadUrl = storageRoot + bucketName + encodeURIComponent(dest);
