Bulk Subscriptions

You can subscribe to multiple topics at the same time.

To do so, send a JSON array of subscribe messages instead of a single subscribe message. For example this code subscribes to three topics:

1[
2  {
3     "channel": "/meta/subscribe",
4     "clientId": "Un1q31d3nt1f13r",
5     "subscription": "/topic/foo"
6   },
7  {
8     "channel": "/meta/subscribe",
9     "clientId": "Un1q31d3nt1f13r",
10     "subscription": "/topic/bar"
11   },
12  {
13     "channel": "/meta/subscribe",
14     "clientId": "Un1q31d3nt1f13r",
15     "subscription": "/topic/baz"
16   }
