Package Exports

obs-store
obs-store/lib/composed
obs-store/lib/localStorage
obs-store/lib/transform

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (obs-store) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ObservableStore

ObservableStore is a synchronous in-memory store for a single value, that you can subscribe to updates on.

const store = new ObservableStore(initState)
store.subscribe(function showValue(value) {
  console.log('saw value:', value)
})

store.putState(5) // "saw value: 5"
store.putState(true) // "saw value: true"
store.putState({ hello: 'world' }) // "saw value: { hello: 'world' }"

console.log(store.getState().hello) // "world"

streams

Each ObservableStore is a duplex stream. You can pipe new values into it and pipe its updated values out of it.

const pipe = require('pump')

const storeOne = new ObservableStore(initState)
const storeTwo = new ObservableStore()

pipe(
  storeOne,
  transformStream,
  storeTwo
)
