One Router to Rule Them All: React Router

Mat Warger JavaScript, React, Technology Snapshot Leave a Comment

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.



Angular Developer: JavaScript to TypeScript

Chris Shatrov AngularJS, JavaScript, React, TypeScript Leave a Comment

New JavaScript frameworks and libraries are created every day. This generates a dilemma: which solution should we use when starting a project?

My web development experience over the last few years has mainly included the AngularJS and Backbone.js frameworks. Angular, jQuery and traditional JavaScript have been in my comfort zone. When I ended up being face-to-face with TypeScript, it felt new, scary, and pretty confusing. I want to make that transition easier for you!

The goal of this post is to provide you an understanding of TypeScript, particularly when you come from an Angular web development background. To do so, we will first give an introduction to TypeScript. We will then discuss the differences between the different versions of Angular & Angular vs. React, with an eye for what you need to know to understand the JavaScript tooling landscape TypeScript plays in. And, lastly, we’ll go through a tangible TypeScript example for a look into syntax & structure.



Advanced Node.js Process Management with PM2

Matthew Brown JavaScript, Node.js, Technology Snapshot, Tutorial 1 Comment

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 JavaScript, React, Technology Snapshot, Tutorial Leave a Comment

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….



An Example Progressive Web App on Android

RJ Dela-Cruz AngularJS, JavaScript, Mobile, Technology Snapshot Leave a Comment

In my experience, the best way to learn a new technology is to create something tangible with it. I recently sought out to learn Angular and Angular Material. So, I developed an experimental Angular app that uses omdbapi to query Movie Posters. It’s aptly named Movie Poster Finder.

Developing the Movie Poster Finder application, I ran into a thing called PWA, which is also known as Progressive Web Applications. I thought it was really neat that both Android and mobile Chrome treat them as native applications.

In this post, I will show an example Progressive Web Application in action, explaining what I encountered when turning an experimental Angular web application into a PWA.
