Warning: The StrongLoop pub-sub modules are not yet at version 1.0. The API and behavior will most likely change before the 1.0 release.
Strong-pubsub is a library of modules that implement the basic publish-subscribe programming model without a strict dependency on any transport mechanism (websockets, HTTP, and so on) or protocol (MQTT, STOMP, AMQP, Redis, and so on).
Instead of implementing a specific transport, strong-pubsub enables you to swap out an underlying adapter that implements a pub-sub protocol (for example MQTT). It also enables you to swap out an underlying transport (TCP, TLS, WebSockets, or even Primus).
The following table summarizes all the pub-sub related modules.
Tip: For more background and information, see the StrongLoop blog post on pub-sub.

Strong Pub-sub
API documentation |
Main StrongLoop pub-sub module. It exports a Client class that provides a unified pubsub client in Node.js and browser (client JavaScript). It supports subscribing to topics. Clients can connect to brokers or proxies that support the client adapter’s protocol. |
| strong-pubsub-bridge | Pub-sub bridge
API documentation |
Enables Clients to connect to a broker indirectly so a client using one protocol can connect to a broker that requires another andc reating hooks to inject logic between the client and the broker to implement authentication and authorization. |
