Why You Should Use React Native For Your Next Mobile App

I believe there is a wide misconception about developing mobile applications. Many seem to think that the only proper way to create a phone app is by engineering it natively. This splits codebases, increases costs, and consumes more resources. Depending on your needs and how fast it’s required to be done, this is not always ideal. Herein lies the cross-platform and single-source solution: React Native. There was not an instance where I directly experienced a conversation about choosing betw

Evaluating Your Tech Stack: Content Management Systems

Choosing a content management system is kind of a big deal. It’s a choice that has a lasting legacy for any company, and migrating from an existing system to a new one is complicated at best. Given the multitude of options available, it’s interesting to me that most people default to “something like Wordpress”, which usually means actually Wordpress. And while Wordpress has its place, it’s hardly a one size fits all solution. The core problem with making this very important choice is just tha

From RxJava to LiveData (and back?)

Disclaimer: I'm no Reactive Extensions [http://reactivex.io/] (RX) expert. I'm simply a happy user with some (~6 years) experience with it. I've seen people struggling with RX. They say it has a steep learning curve. In that light, I was super excited when I first heard about Google's Android Architecture Components [https://developer.android.com/topic/libraries/architecture/] (AAC) and LiveData [https://developer.android.com/topic/libraries/architecture/livedata].

Organizing AWS microservices with Python, Serverless, and namespace packages

Our project began with a small ask: build a small Python back-end using AWS Lambda and API Gateway (with just a handful of endpoints to support a few pages) and use Serverless [https://serverless.com/] to manage the Cloud Formation setup. Not very involved, not much code, not even much configuration for the deploy. Next came authentication. In pursuing the joint dreams of DRTW ("don't reinvent the wheel") and WALCAP ("write as little code as possible"), we selected AWS Cognito over other opti

Deployments at Scale with AWS ECR and ECS

With DevOps at DEPT, one of our primary goals is to make the life of the developer easier. A specialty of ours is assisting in our customer's deployment process. In short, this is how a code change can safely make it from a developer's laptop all the way to a production environment where it can be seen by end-users. In a typical software project, your environments will be something along the lines of dev, staging, and prod. Maintaining a release pipeline to these is simple enough in most cases,

iOS Accessibility: Dynamic Type

Nowadays just about everyone, everywhere, regardless of age and ability, uses a smartphone. With that in mind, it’s more important than ever to consider all the different ways to make your app accessible to everyone to ensure an inclusive experience. In this series, we’ll be discussing different ways iOS developers can make their apps more accessible. First up, we’ll be talking about Dynamic Type. Dynamic Type is a feature on iOS that enables the app’s content to scale based on the user's

Create a Rust web service, from zero to cloud

Rust is a fantastic general-purpose language with a rich and expressive type system, but one of the reasons the language is so loved [https://insights.stackoverflow.com/survey/2021#section-most-loved-dreaded-and-wanted-programming-scripting-and-markup-languages] is the overall developer experience. Writing software can be very complex in any language. Working with the language and tools, however, should not be. This is an area where Rust shines! This tutorial will describe how to... * Insta

How to Build a full page calendar with React

As a developer, I can’t help but get excited when I see immersive apps built on the web. I love it when I get to build things that are a little bit “out of the ordinary”. I recently built a full-page calendar widget. At first, I thought I’d reach for a library, but I found myself a little disappointed with the options in the ecosystem. More importantly, I realized that it’s actually not very hard to build a full-page calendar using modern web technologies. Because it doesn’t take much code and

Reusable Patterns in CloudFormation

At DEPT, we use a variety of tools to provision infrastructure in the cloud. In this post, we take a look at some of the reusable patterns we've developed using AWS CloudFormation. What is CloudFormation? If you've ever created infrastructure and/or resources in AWS then there's good chance you've used or at least heard of CloudFormation. For those who are unfamiliar, CloudFormation is an AWS service that allows you to provision and configure almost all AWS resources using yaml (or json) templa

GitOps with Terraform, Terragrunt and GitHub Workflows

At DEPT, we love pushing the envelope of new technologies and tooling to deliver best-in-class products and solutions that delight our clients. We use Terraform and Terragrunt to build and provision as much as we possibly can, and recently we've begun leveraging GitHub Workflows for CI/CD. In this post, we'll take a look at how we combine these tools to create a GitOps centric workflow for managing cloud infrastructure. Specifically we'll: * Define GitOps * Review a sample Terraform app mod

CI/CD with CodeBuild and CodePipeline

At DEPT we use a variety of hosted continuous integration / continuous delivery (CI/CD) platforms to help our clients deliver great products and experiences to their customers. Recently, we've used a few of AWS's services to create full integration and delivery solutions. In this post we'll look at how we've used AWS CodeBuild and CodePipeline to create a cost effective, performant and code driven end-to-end CI/CD solution. What is CodeBuild and CodePipeline?

Securely Storing Data on iOS

Our mobile devices and the apps that run on them have a unique insight into our lives. We use them for communication, entertainment, shopping, photography, navigation, and myriad other purposes. Consequently, apps have access to a great deal of information about our preferences, our contacts, where we go, what we buy, and who we are. As app developers, we need to be cognizant of the information being handled by our apps and to safeguard it accordingly. The protection of sensitive information is

Using Unity with Swift for AR

Since the introduction of ARKit with iOS 11, we've seen an increasing demand for applications incorporating some form of Augmented Reality (AR) experience. AR is a relatively new technology that enhances the user's real world with virtual audio/visual objects, and a mobile phone or tablet is a perfect platform for this tech. In this post, I’ll dive into some of the technical challenges of AR as well as our preferred solution, focusing on integrating Unity into an iOS project. The first techni

It has been edited for clarity. What is SQL? SQL is a family of programming languages used to communicate with a database. These languages are different, but they’re similar enough that we can call them a family. One thing to note is that pronouncing it “sequel” or “SQL” are both totally valid options so continue saying
