sforcejs v1.0.5

Sforcejs :: node.js salesforce REST API wrapper with backpressure

Sforcejs is a copy of the nforce module with support for streaming backpressure by using the Bayeuxjs package, instead of Faye. The following is an example of the additional feature this package provides.

Streaming Client

Lastevent trigger

The lastevent event is triggered after the last data event of the current page has been triggered. The lastevent event will receive a callback as a parameter that will request additional events when called. This mechanism provides a way to control the flow of events from the data source.

org.authenticate({ username: user, password: pass }, function(err, oauth) {

  if(err) return console.log(err);

  console.log('subscribing to NewAccounts');
  var accs = org.subscribeAsync({ topic: 'NewAccounts' });

  accs.on('error', function(err) {
    console.log('subscription error');
    console.log(err);
    client.disconnect();
  });

  accs.on('data', function(data) {
    console.log(data);
  });
    
  accs.on('lastevent', lazyConnect => {
    console.log("lastEventReceived. Requesting more events");
    setTimeout(lazyConnect, 5000);
  });


});
