Searching for “download ReadableStream”, I find two questions:
- Download Readablestream as file
- How to download a ReadableStream on the browser that has been returned from fetch
Both have answers ending up in collecting all the data in a Blob and using URL.createObjectURL. Yet having a ReadableStream, it is a waste to first create a huge Blob in memory before the browser can start the download operation.
Is there a way to let the client download directly from a ReadableStream, without first collecting all data in memory?
NOTE: this ReadableStream is created by the client from lots of data, so relying on fetch Response objects will hardly be a solution.
