如何使Firebase存储中的图像加载速度更快？

Question

Loading images from firebase storage is very slow, it was taking more than 2sec to show image in my web page. Is there any way to seed up image loading? Will it seed up when give read access to world Like: allow read: if true ?

Please guide me, what is the best way to upload and download images from firebase storage? Thanks.

Following is my Storage Rule:

service firebase.storage {
  match /b/test-project-faac7.appspot.com/o {
    match /{allPaths=**} {
      allow read: if request.auth != null;
      allow write: if request.auth != null;
    }
  }
}

Code to get Download Url :

 this.storage.ref(item.imgQuestion).getDownloadURL().then(url => {
    item.imgQuestionUrl = url;
 })

You could create a cloud-function where the image can be compressed after upload and replace the original image. You can follow this sample to get some idea. You will need to watch for storage upload to trigger your functions.
