A persistent client-server coordinated storage based on client domain cookies with a local-storage fallback.
Name:
universal-storage
Installation
npm install --save universal-storage
Usage
In client-side code.
import { discardClientStorage, getClientStorage } from 'universal-storage';
let storage = getClientStorage(); // establishes a client storage singleton
storage.current.setItem( 'key', 'value' );
storage.current.getItem( 'key' ); // 'value'
storage.current.removeItem( 'key' );
storage.current.getItem( 'key' ); // undefined
storage.current.setItem( 'key', 'value2' );
storage.current.getItem( 'key' ); // 'value2'
discardClientStorage(); // destroys the current client storage singleton
storage.current.getItem( 'key' ); // error! cannot read getItem of undefined; reading 'storage.current'
storage = getClientStorage(); // reestablishes a client storage singleton
storage.current.getItem( 'key' ); // 'value2'
In server-side code.
import { discardServerStorage, getServerStorage } from 'universal-storage';
let storage = getServerStorage(); // establishes a client storage singleton
storage.current.setItem( 'key', 'value', e.response );
storage.current.getItem( 'key', e.request ); // 'value'
storage.current.removeItem( 'key', 'value', e.response );
storage.current.getItem( 'key', e.request ); // undefined
storage.current.setItem( 'key', 'value2', e.response );
storage.current.getItem( 'key', e.request ); // 'value2'
discardServerStorage(); // destroys the current client storage singleton
storage.current.getItem( 'key', e.request ); // error! cannot read getItem of undefined; reading 'storage.current'
storage = getServerStorage(); // reestablishes a client storage singleton
storage.current.getItem( 'key', e.request ); // 'value2'
