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.

Variable types

There are four types of variables that we need to understand to optimize our frontend workflow: session, persistent, file scope, and ReactiveVar. With these variables, we can build dynamic sites easily based on how the user is interacting with the view.

The session variables are variables that exist only during a session. A session begins whenever a user hits the site. These variables can be shared across routes and are reactive.

The persistent variables are variables that are stored in local storage so that they can be read even after the session closes.

The file scoped variables are variables that only exist within the scope of the file. These are generally not reactive.

The ReactiveVar variables can be scoped to the file or globally and are reactive. These variables do not persist the way session variables do.

Session variables

Some Meteor developers believe that session variables are overused. This is definitely true, if you are not managing them. For the most part, session...
