Toptal’s GitHub Organization Hijacked: 10 Malicious Packages Published
Threat actors hijacked Toptal’s GitHub org, publishing npm packages with malicious payloads that steal tokens and attempt to wipe victim systems.
workbox-sw
Advanced tools
This module makes it easy to get started with the Workbox service worker libraries.
The workbox-sw npm package is a library that simplifies service worker creation and management, making it easier to build robust, offline-first web applications. It provides a set of tools to cache assets and other resources, handle background sync, and manage runtime caching strategies.
Precaching
This feature allows you to specify a list of URLs and their corresponding revision details to be precached when the service worker is installed. This is useful for ensuring that your app's core resources are cached and available offline.
import { precacheAndRoute } from 'workbox-precaching';
precacheAndRoute(self.__WB_MANIFEST);
Runtime Caching
Runtime caching enables you to use various caching strategies for different types of requests. This example uses the NetworkFirst strategy, which tries to fetch the latest content from the network, but falls back to the cache if the network is unavailable.
import { registerRoute } from 'workbox-routing';
import { NetworkFirst } from 'workbox-strategies';
registerRoute(
({request}) => request.destination === 'document',
new NetworkFirst()
);
Background Sync
Background Sync allows you to defer actions until a stable network connection is detected. This is particularly useful for ensuring that user actions, like posting comments, are not lost when the app is offline.
import { BackgroundSyncPlugin } from 'workbox-background-sync';
const bgSyncPlugin = new BackgroundSyncPlugin('myQueueName', {
maxRetentionTime: 24 * 60 // Retry for max of 24 Hours
});
sw-toolbox is a predecessor of workbox-sw, offering similar features like dynamic caching and offline support. However, workbox-sw provides a more modular and flexible approach, with better support for modern web standards.
sw-precache is another predecessor to workbox-sw that focuses on static resource caching. Unlike workbox-sw, it does not offer extensive runtime caching strategies or background sync capabilities.
