sse-fetcher v1.0.1

SSEFetcher

This a class that reads server sent events using fetch(). It works in Edge (which doesn't support EventSource) if you have a TextDecoder polyfill.

Usage

const sse = new SSEFetcher(url, opts);
// opts.withCredentials - Send cookies to cross-origin URLs.
// opts.reconnectionDelay - Initial reconnection delay.

(async function() {
  while (true) {
    const message = await sse.nextMessage();
    console.log(message);
    // message.data - Data sent
    // message.type - Event type sent
  }
})();

// Later, stop events & close the connection.
sse.close();
