localstorage-fifo-queue

Storage queue

This package contains a persistant FIFO queue implementation working with localstorage. It can enqueue and dequeue items, as well as peek the next item without deleting it.

Usage

import { LocalStorageQueue } from './src/local-storage-queue';
 
interface Message {
    hello: string;
    world: number;
}
 
const queue = new LocalStorageQueue<Message>('myQueue');
queue.initialize();
 
queue.enqueue({
    hello: '123',
    world: 123
});
 
queue.enqueue({
    hello: '456',
    world: 456
});
 
queue.peek(); 		
// { hello: '123', world: 123 } item still in the queue
 
queue.dequeue(); 	
// { hello: '123', world: 123 } item deleted from queue
 
queue.dequeue(); 	
// { hello: '456', world: 456 } item deleted from queue
 
queue.dequeue(); 	
// null	 queue is empty
