Receiving streamed data in Express sent from controller

I've been following the instructions in an article I found here, and while I've managed to get it working in the controller, I don't know how to stream the data to the route that called it.I'm struggling with this because I don't know what questions to ask, and the articles I find on streaming are for files and not data.So, the controller is:services.buildIndices = async (params) => { const createCounterReader = (delay) => { let counter = 0; const reader = new Readable({ objectMode: true, read() {}, }); setInterval(() => { counter += 1; console.log('reading:', counter); reader.push(counter); }, delay); return reader; }; const counterReader = createCounterReader(1000); const logWriter = new Writable({ objectMode: true, write: (chunk, _, done) => { console.log('writing:', chunk); done(); }, }); return counterReader.pipe(logWriter); } ... and the route is:router.get('/elastic/indices/:typeOfAsset/build', async (req, res) => { const buildIndices = await controllerElastic.buildIndices(req.params); res.json(buildIndices) }) What would I need to do to get the controller to stream the count into the route, which in turn passes the stream onto the component in Vue?
