Meteor Design Patterns

By: Reyna

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.

Publishing with relations

We understand how our collections are related, but how can we make it easy to publish data with these relationships?

In Meteor, it can be problematic to publish relationships because of reactivity and the way publishers work. You would expect that by simply making two queries to two related collections and returning an array will publish a perfectly reactive collection. This is not the case. A Meteor.publish function does not rerun when dependencies change. This means that if a relationship is broken, the related document will remain published, or worse if a new relationship is made by another client, the related data will not publish.

To take care of database relationships and reactivity in Meteor, we use the lepozepo:publish-with-relations package. This package automatically takes care of subscribing to new data in the most efficient way possible when relationships are broken. If you are familiar with MySQL, this package makes JOINs a breeze.
