# 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

```js

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();

```
