immview

Immview is a library to create Domains - non-visual components

• similar to flux stores, exposing their state or emitting signals through Observables pushing values and having specific to their concerns actions. Their primary role is to encapsulate a concern and to be the only thing exported from a javascript module or modules that deal with the concern.

It completely replaces any flux implementation or Redux.

All Domains must be provided with a single stream of values (so either Origin or any other transformed Observable), but not all Observables must be attached to a Domain

• you can perform many transformations on a source before it is exposed through a Domain.

For RxJS users

If you are familiar with RxJS 5, an Immview taste of Observable does not have a different meaning or role, although behaviour differs and is more similar to RxJS's Subject Also, just as RxJS 5, it mimics TC39 Observable proposal interface.

Quick overview

const Foos = new Observable()
const FooSenderDomain = Domain.create(Foos, {
  send() {
    Foos.next('foo')
  }
})

// register observers
FooSenderDomain.subscribe(v => console.log(v))
FooSenderDomain.map(v => v + 'bar').subscribe(v => console.log(v))

FooSenderDomain.send()
// prints: foo
// prints: foobar
