Advanced Web-Push JavaScript SDK

Zero-Bloat Service Worker Architecture

Modern web performance is defined by Core Web Vitals. Injecting a massive, blocking third-party marketing script into your website destroys your Time to Interactive (TTI) and actively harms your SEO. VipulPush engineered our advanced web-push JavaScript SDK to be the lightest in the industry. Written in pure, vanilla JavaScript, the script executes entirely asynchronously. It registers the required service worker without ever blocking the browser's main thread, ensuring your website maintains a flawless Lighthouse score.

import { VipulPush } from '@vipulpush/browser';

const push = new VipulPush({
  appId: 'vp_live_x8f92j',
  strategy: 'edge-first'
});

await push.identify(user.id);

Seamless Edge VAPID Authentication

Managing cryptographic VAPID handshakes on your own backend is a complex, error-prone process. If a key rotates poorly, your entire subscriber base goes offline. Our advanced web-push JavaScript SDK completely abstracts this complexity. The SDK securely passes your public key to the browser, while the actual heavy JWT cryptographic signing is handled instantly by our Edge-Native Workers. This guarantees a highly secure, zero-latency registration process without burdening your origin server.

Secure Subscriptions via D1 Shards

When a user opts into your web push notifications, their unique browser endpoint is highly sensitive PII. Storing these endpoints in a massive, multi-tenant marketing cloud is a significant privacy risk. VipulPush isolates this data immediately. As soon as our advanced web-push JavaScript SDK captures a new subscriber, their endpoint and behavioral metadata are heavily encrypted and saved directly into your dedicated D1 Shard, guaranteeing absolute enterprise data sovereignty.

Scale Globally at a Flat Rate

Acquiring web push subscribers should be a highly profitable growth loop, but legacy providers turn it into a liability by charging you per active subscriber. The larger your audience grows, the more you are penalized. VipulPush disrupts this model with transparent, flat-rate pricing. You can deploy our advanced web-push JavaScript SDK across high-traffic media sites or global e-commerce stores, capturing millions of subscribers without ever triggering variable infrastructure fees.
