import { Queuer } from '@wareset-utilites/queuer'

const timeout = (time = 0, cb = () => {}) => {
  return new Promise((resolve) => setTimeout(() => resolve(cb()), time))
}

const queuer = new Queuer('FIRST_DATA')

queuer.add(
  (data) => {
    queuer.add(
      data,
      (data) => console.log('1', data) || 'after 1',

      (data) => {
        queuer.add(
          // Automatically turns into a function
          console.log('2', data) || 'after 2',

          async (data) => {
            await timeout(500, () => console.log('...SLEEP 500'))
            return 'after SLEEP 500'
          },

          (data) => console.log('2-1', data) || 'after 2-1',
          (data) => console.log('2-2', data) || 'after 2-2',

          async (data) => {
            await timeout(1000, () => console.log('...SLEEP 1000'))
            return 'after SLEEP 1000'
          },

          (data) => console.log('2-3', data) || 'after 2-3'
        )

        return 'SECOND_DATA '
      },

      (data) => console.log('3', data) || 'after 3',
      (data) => console.log('4', data) || 'after 4',
      (data) => console.log('5', data) || 'after 5',
      (data) => console.log('6', data) || 'after 6'
    )
  },

  () => {
    queuer.add(
      'SOME_DATA',
      (data) => console.log('7', data) || 'after 7',
      (data) => console.log('8', data) || 'after 8',
      (data) => console.log('9', data) || 'after 9',
      (data) => console.log('10', data) || 'after 10',
