You don't need to add a whole npm lib for a single file. i refactored it to typescript:

import { Readable, ReadableOptions } from "stream";

export class MultiStream extends Readable {
  _object: any;
  constructor(object: any, options: ReadableOptions) {
    super(object instanceof Buffer || typeof object === "string" ? options : { objectMode: true });
    this._object = object;
  }
  _read = () => {
    this.push(this._object);
    this._object = null;
  };
}

based on node-streamifier (the best option as said above).
