One Router to Rule Them All: React Router

Previously, we looked at a very basic example of how one can benefit greatly by using community projects such as Formik to avoid the tedium of certain solutions while embracing convention to create composable and scalable applications. We will be build on that foundation to explore the objectively great library that is React Router.

React Router has been at the forefront of routing in the React ecosystem for as long as I can remember. If you’re new to React, this is the way to go when you move state and start needing more options such as parameterized routing, nesting, and conditional rendering. If you have experience with React, this brings a powerful pattern to bear in that everything is a component. It takes the composablity of React and uses that to its benefit, handling any and all use-cases with relative ease.

In this blog, we’ll introduce the basics of the React Router through hands-on examples using its features.

Explosive Tutorial With Unity3D and VRTK

Opinions on the emerging Virtual Reality market vary. One one end, there are those who say it’s just a gimmick and will pass shortly. On the other end, there are those who herald it as the birth pangs of a paradigm shift in how we interact with technology.

I sit somewhere in the middle. I own an HTC Vive and it is pretty dang awesome. The experience is not perfect, of course, but with interest growing and prices coming down, it’s just going to get better.

One expression of VR’s growing popularity is that Unity3D supports VR programming. And, with the free VRTK (Virtual Reality Tool Kit) framework, it’s becoming much easier to get started programming for VR. VRTK implements many basic components, such as various movement implementations, object interaction, and projectiles.

Working on a fun little side project, I noticed one implementation it did not have: a virtual reality bomb. So, I set upon to create one myself. This post details the process I went through for creating a timed, throwable, explosive object for virtual reality using Unity3D & VRTK.

Advanced Node.js Process Management with PM2

If you’ve worked on any front end applications recently, you have likely had some contact with a Node/Express application. What you may not be familiar with is how these applications are managed in production.

I recently had a project where I needed to set up a Node application on an AWS server. I needed a tool to solve the technical challenges of managing the Node processes and deploying the application in a very efficient manner.

I chose PM2, which is a handy process management tool for running Node.js applications in production environments. PM2 provides a simple command line interface that makes it easy to get started. This powerful Node module has tools for managing application processes, logging, and more.

In this article, I provide an introduction to PM2, showing why it is such a valuable tool for managing Node.js applications. By way of a reference example application, we show the basic features and commands for using PM2 and give examples of generating configuration files for both running and deploying applications.

The Joy of Forms with React and Formik

Mat Warger Articles, Development Technologies & Tools, JavaScript, React, Tutorial 9 Comments

React is a JavaScript library for building user interfaces. That’s it. It’s a way to use JavaScript to define UI elements based on user-defined properties and internal state.

It has a clean, functional style. You can create simple components that compose very well into larger components, which you can then use to compose pages and entire applications. This simple composability is one of the main reasons I enjoy working with it.

But, it is not an application framework. It doesn’t pretend to be. This can be useful when all you want is some quick UI. But, as the application grows, you will need to depend on outside libraries for things like state-management, routing, and forms.

In this article, learn how to handle form input with React, from basic form input using simple state through advanced form components using Formik….
