Response readable stream?

Question

Node.js

Hello. And do not tell me how to return json readable stream in which chunk object through response?

const http = require('http');
const { Readable } = require('stream');

http.createServer((request, response) => {
  const data = [{ a: 1 }, { b: 2 }, { c: 3 }, { d: 4 }, { e: 5 }];
  const readable = Readable.from(data, { objectMode: true });
  readable.pipe(response);
}).listen(8080);

events.js:187
      throw er; // Unhandled 'error' event
      ^

TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be one of type string or Buffer. Received type object

}

Thank you.

Try like this

const readable = Readable.from(Buffer.from(data), { objectMode: true });
