How to convert Web Stream to NodeJS native Stream

Question

I am taking file input from user as

<input type="file"/>

It returns file object has Blob. This object has a method .stream() which returns ReadableStream. Now, i want to pass this stream to stream-json library. But it takes NodeJS native stream - Readable. Now, how do i convert the ReadableStream (webstream) to Readable (node stream) ?

Answer 1

Node has an helper function:

Another more complex way is to implement a node stream that consumes the web stream.
