cycle.js使うとエントリポイント大体こうなる.js

import { makeDOMDriver } from '@cycle/dom';
import Cycle from '@cycle/core'
import intent from './intent'
import model from './model'
import view from './view'

Cycle.run(
  ({ DOM }) => {
    return { DOM: view(model(intent(DOM))) };
  },
  {
    DOM: makeDOMDriver('body')
  }
);
