Meteor Design Patterns

Overview of this book

With the increasing interest in NodeJS web applications, a new framework, Meteor, has joined the ranks to simplify developer workflows. Meteor is one of the few open source frameworks that has received funding since its early development stages. It builds on ideas from existing frameworks and libraries, offering developers an easy way to develop a prototype app. At the same time, it gives them the tools and flexibility to build a fully fledged production app. Meteor is the weapon of choice for start-ups in today’s world. Meteor Design Patterns cuts through the jargon that most websites play with and gets to the point with simple solutions that will boost your development skills. We start off with a refresher on the basics of JavaScript programming such as templates, CoffeeScript, the Event Loop, and the Merge Box, amongst others. You then learn how to map real-world data and optimize the data’s publishers to output data with the least amount of work done by the server with some subscribe and publish patterns. Next, using front-end patterns, you will learn how to create maintainable and trackable forms, and make our site crawlable by any search engine. Following this, you will see how to optimize and secure the web application and maintain applications without breaking other features. Finally, you will learn how to deploy a secure production-ready application while learning to set up modulus, compose with Oplog tracking and SSL certificates, as well as error tracking with Kadira. Throughout the book, you will put your skills to practice and build an online shop from scratch. By the end of the book, you will have built a feature-rich online shop.

Chapter 2. Publish and Subscribe Patterns

This is by far the most important chapter in this book. The way we control our publishers and subscribers is going to define how quickly our application responds in production. Publishers and subscribers are the link between our database and the client. The server uses publishers to publish information to the client, while the client requests information from the publishers by subscribing to them. This is all managed via the Meteor.publish and Meteor.subscribe functions. We should be able to produce the data that the client wants to see with two objectives in mind:

  • Reduce stress from the server
  • Send only the information that the client needs

This chapter will teach you the different patterns that you can use to attain these objectives for every template that you build. Here is an overview of the topics we will cover to understand these patterns:

  • Template-level subscriptions
  • Database relationships
  • Publishing with relations
  • Aggregation publishers...
