Start/stop following CouchDB changes listener

startstop.js

const nano = require("nano")("http://localhost:5984");
const name = "test";

nano.db.destroy(name, () => {
  nano.db.create(name, () => {
    const db = nano.use(name);
    const feed = db.follow({ since: "now" });

    // add doc every second
    const timer = setInterval(() => {
      db.insert({}, (err, body) =>
        console.log(err ? "ERROR" : "ADD " + body.id)
      );
    }, 1000);

    const handler = change => console.log("GOT " + change.id);
    feed.on("change", handler);

    // start feed after 5s
    setTimeout(() => feed.start(), 5000);
    // stop feed after 10s
    setTimeout(() => {
      clearInterval(timer);
      feed.stop();
    }, 10000);
  });
});

Running this bombs out with :
