import { WsReconnect } from '../src/WsReconnect';
const ws = new WsReconnect({ reconnectDelay: 5000 });
ws.open(`ws://${host}:${port}`);
ws.on('open', function open() {
// this will only be called once, not on reconnect
});
ws.on('reconnect', function open() {
// this will only be called on every reconnect attempt
});
ws.on('message', (data: string) => {
const json = JSON.parse(data);
console.log('======== received', json);
});
ws.on('close', () => {
interval && clearInterval(interval);
});
