node.js - How to wrap a buffer as a stream2 Readable stream?

Question

How can I transform a node.js buffer into a Readable stream following using the stream2 interface ?

I already found this answer and the stream-buffers module but this module is based on the stream1 interface.

The easiest way is probably to create a new PassThrough stream instance, and simply push your data into it. When you pipe it to other streams, the data will be pulled out of the first stream.

var stream = require('stream');

// Initiate the source
var bufferStream = new stream.PassThrough();

// Write your buffer
bufferStream.end(Buffer.from('Test data.'));

// Pipe it to something else  (i.e. stdout)
bufferStream.pipe(process.stdout)
