@binance/web-push-sdk is a client-side notification pushing SDK based on firebase-js-sdk that provides utilities to make and manage pushing subscription.


yarn add @binance/web-push-sdk


import { subscribe, canSubscribe, canUpdateSubscription, ErrorCode } from '@binance/web-push-sdk'
import { useEffect, useState } from 'react'

const updateSubscriptionTimeout = 2000

export default function Page() {
  const subscribeHandler = () => {
      .then((result) => {
        if (result) {
          // do something after success
      }).catch((e) => {
        if (e.code === ErrorCode.PERMISSION_DEFAULT) {
          console.warn('user closed the notification permission requesting popup')
  const [showSubscribe, setShowSubscribe] = useState(false)
  useEffect(() => {
    const initSubscribe = async () => {
      if (await canUpdateSubscription()) {
        setTimeout(subscribeHandler, 2000)
      } else if (canSubscribe()) {
  }, [])
  return (
      { showSubscribe ? <button onClick={subscribeHandler}>Subscribe</button> : null }

This is an example that, when the page is loaded, it will show subscribe button if the device has not subscribed and will update subscription if the user has subscribed.


subscribe(): Promise<boolean>

To make subscription if has not subscribe or update subscription if has subscribed.

  • Returns Promise<boolean> Whether the subscribe is successful. Will throw error if unsuccessful.

This method will register a service worker and get pushToken from Google. Then report the pushToken and other information to the backend.

The pushToken will expire in 7 days so we need to update subscription regularly.
