Node.js the Right Way

Wrapping Up

This chapter brought us out of the Node.js core and into the larger world of npm. We discussed how to install and use third-party modules with binary components. In particular, we covered how to use ØMQ.

ØMQ supports a number of message-passing patterns; we got to know several of them. We saw how ØMQ does the publish/subscribe pattern, the request/reply pattern, and the PUSH/PULL pattern. These patterns are now tools at your disposal for designing networked applications in Node.js, even if you choose not to use the ØMQ library itself.

We also explored Node’s clustering capabilities. Using features of Node’s cluster module, we spun up a number of worker processes and distributed requests to them. We’ll use these capabilities ...
