How do I retrieve files from storage?

Fetching files from storage is achieved by using History API in combination with Files SDK methods:

1. Obtain the file message using History API, or listFiles method.
    History API response doesn't include file URL. It returns file details (ID, filename) and a message type of 4, indicating a file message. This information is used for file retrieval.
2. Display/download the file using SDK methods based on the obtained file information.

The code below is used to create a file URL that allows you to display the file in your browser: 

Javascript//

const result = pubnub.getFileUrl({ 
  channel: 'my_channel', 
  id: '1234', 
  name: 'picture.jpg' 
});

To download a file, the same file information is used along with file URL information:

const file = await pubnub.downloadFile({
  channel: 'my_channel',
  id: '1234',
  name: 'picture.jpg',
});

const myImageTag = document.createElement('img');
myImageTag.src = URL.createObjectURL(await file.toFile());

document.body.appendChild(myImageTag);
