    Install

    npm i browser-unhandled-rejection

    or

    yarn add browser-unhandled-rejection

    Usage

    Automatic polyfill

    This automatically applies the polyfill to the global Promise object if it is needed.

    import {auto} from 'browser-unhandled-rejection';
     
    auto(); // Applies polyfill if necessary to window.Promise

    Manual polyfill

    The following snippet is equivalent to auto():

    import {polyfill} from 'browser-unhandled-rejection';
     
    if (typeof PromiseRejectionEvent !== 'undefined') {
      polyfill(); // Polyfills window.Promise
    }

    Ponyfill

    This may may useful if you don't want to mutate window.Promise:

    import MyPromise from 'browser-unhandled-rejection';
     
    window.addEventListener('unhandledrejection', () => {
      console.log('unhandledrejection was triggered');
    });
     
    MyPromise.reject('will trigger unhandledrejection event');
     
    new MyPromise((resolve, reject) => {
      reject('will also trigger unhandledrejection event');
    });
