At a high level, micro-frontends are a software development approach that breaks down a monolithic frontend application into smaller, individual mini applications.

A recent client had a requirement to add comment sections to articles on their site. The ask was to have the sections maintain the site's branding for a nice, unified digital experience. Could it be done?

Your site has gone down. Users are contacting you for support, but you have no idea what could be causing the issue. Mild panic sets in. This scenario is all too common, and recently, I also encountered this issue. It turned out that the problem was not in the code I had recently written; but in my failure to realize the software development kit (SDK) I was using was deprecated. This article will explore the risks of using an outdated SDK and provide tips to avoid its pitfalls. So, what exa

NeMo is a toolkit provided by NVIDIA that allows you to use modules (reusable components) for a variety of AI tasks. Components like encoders, decoders, loss functions and more.

At DEPT® we believe that Kotlin Multiplatform is a true game-changer. By sharing business logic between platforms, we had the opportunity to shift our focus to the UI aspects of an app.

We've updated and open-sourced Terraform scripts to bootstrap your own Mastodon server using AWS, Elastic Container Service and Fargate.

The what could be described as a cross-platform solution for mobile development. But, there is a big difference between a cross-platform solution and Kotlin Multiplatform Mobile.

With a React frontend, Django isn't responsible for the frontend and doesn't know how to start the frontend process. This causes the tests to fail due to there being no frontend to interact with. To fix the failing tests we need to have the frontend running when running the integration tests.

What if you could catch badly performing queries during your local development process? The Spring Boot SQL Explain library does this for you.

Unit tests for APIs can sometimes provide little to no value, so the next logical step is often to write integration tests. You don’t want to touch live data though, and want tests to make assertions against actual (un-mocked) service logic. The following is an approach to do just that.

I know what you're thinking because that's my reaction when I hear something like this, so I get it. But it's not like that, I swear.

Templates may use configurations adding up unnecessary expenses. Here's my journey to move away from this config to reduce this project's AWS cost.

How do you integrate data models in a source control repository into a database, using a CI/CD process?

What we're trying to do is break down our part one and two, how you can immerse yourself in this world to learn it the fastest and come to appreciate it. Let's talk about “do you have to care about the project or not?”

AWS tags are key-value labels you can assign to AWS resources that give extra information about it.

Rust helps mitigate concurrency hazards by design, but it's still up to the programmer to construct their program logic thoughtfully so they can take advantage of the power of concurrent and parallel processing.

“Is the data ready?” Or more accurately, “Can I be confident that this data is correct?”

Many seem to think that the only proper way to create a phone app is by engineering it natively. In this post, I break down why React Native is a great way to build an app.

This week we released a Github project called web-blueprint that documents our practices and opinions on web development. If you're a prospective client or hire, our hope is that you'll learn a little bit more about what web engineering at Rocket is all about.

We recently completed a project with one of the largest affiliate marketing consulting firms in the US which turned out to be a great success for everyone involved. We asked one of the lead consultants on the project, Jason Lombardo, to answer a few questions.

2020 was a hell of a year: A global pandemic, a fraught US election, and ... Microservices! 😬

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.

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

This tutorial will describe how to... install Rust, create a new project and manage dependencies, Set up a simple web server, and compile the app and deploy to a virtual server. I'll be working on Ubuntu 20.04 but most of the setup should be the same on macOS or a different flavor of Linux.

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.

In this post, we'll define GitOps, review a sample Terraform app module repo and an associated GitHub Workflow to lint and version the module repo, and review a sample Terragrunt live repo and a GitHub Workflow to apply infrastructure changes.

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.

We were recently transitioning a client to use Heroku build pipelines for their Next.js project that handles most business logic through an external API, including authentication and cookie handling. This pipeline uses Heroku's review apps [https://devcenter.heroku.com/articles/github-integration-review-apps] as well as separate instances for staging and production environments. The client handled their domains through AWS's Route 53 [https://aws.amazon.com/route53/] DNS service. Pointing thei

The following presentation was transcribed from “SQL and Python for Product Managers” webinar, presented by Colorado Product Meetup and senior software engineer, Brian Schiller. It has been edited for clarity.

The following article was created from a 2021 CppCon talk given by Jonah Jolley. One of our clients has a software product that must comply with federal regulations. For them, they must submit technical documents to a governing body. However, in their case, the codebase didn’t accurately reflect what was documented. This led to an unmitigated, unsafe condition. To solve this issue, we used Clang LibASTMatchers to check the codebase and ensure they were indeed compliant. Why Compliance in Cod

Apple delivered several exciting and innovative new APIs for developers at WWDC this year. You might have heard or read about the SwiftUI and Combine revamp, but I want to address the new world of native WebSockets! The historically complicated connection protocol is now delivered as a first class citizen! Before we dive in on how awesome this is, it's important to have a basic understanding of Sockets and the road we've traveled to reach this point. What is a socket? By definition a socket is

Docker is a helpful tool for both developers and ops. It can simplify both the development of an application as well as deployment and management of it. In this post we are going to explore a common pitfall related to developing an application in Docker on the Mac and see what we can do to mitigate the issue and work as productively as possible. Developing in Docker Developing in Docker has a number of advantages over developing directly on your Mac. Before we begin, let’s remind ourselves of a

So, you are about to build a new app and you need at least part of it to update in real-time. Well, we live in a modern world so it’s pretty common to have at least a part of the app update without requiring a user interaction or a page (re)load.

In this post, we’ll be comparing C++ with Rust, sharing our thoughts on when you should use each language, and predicting the future of C++ vs Rust.

Properly configuring and tuning your Airflow deployment to be generally performant can be a nontrivial endeavor. You can easily shoot yourself in the foot if you don’t do it right at first. You’ll discover and experience sporadic bottlenecks in Airflow-wide and DAG-level execution. You’ll apply solutions to those as they arise. You run the risk of developing a fragmented and mystical understanding of Airflow’s goings-on. You’ll have many questions and, frustratingly, fewer answers. Why are more
