使用rxjs5分配对象

Question

Hy, what is functional way to create object and use values from rxjs5 observables?

let _id = myObservableOne.pluck('id')
let _name = myObservableSecond.pluck('name')
let _path = myObservableThird.pluck('path')

let newObj = {
   id: _id,
   name: _name,
   path: _path
}

Answer 1

Depending if the rate of value emissions is equal for all three observables the .zip() operator might do what you need:

const idStream = myObservableOne.pluck('id')
const nameStream = myObservableSecond.pluck('name')
const pathStream = myObservableThird.pluck('path')

Rx.Observable.zip(
  idStream,
  nameStream,
  pathStream,
  (id, name, path) => ({ id, name, path})
)
.subscribe(console.log);
