RxStorage

RxStorage is a simple wrapper class for anything that extends the Storage interface so that they can be subscribed to in the RxJS world.

Installation

NPM

$ npm i @tkfnetwork/rx-storage

yarn

$ yarn add @tkfnetwork/rx-storage

PNPM

$ pnpm add @tkfnetwork/rx-storage

Usage

Using this helper class is fairly simple...

Creation

Create your wrapped storage class

const localStore = new RxStorage(localStorage);
const sessionStore = new RxStorage(sessionStorage);

Observing

You can now observe storage keys by doing the following

const someValue$ = localStore.getItem$(key);
  
someValue$.subscribe(value => {
    console.log(value) // Will emit the value when it changes
});

// Setting a value into the storage as normal
// will emit the value to any subscribers (if the
// key already existed inside the storage instance)
localStore.setItem(key, value);

You can still get the storage as normal

const someValue = localStore.getItem(key);

Other tabs/windows/frames

RxStorage class automatically listens for storage changes in other tabs and windows and will automatically sync changes into your active instance
