Automate open source security tracking with the WhiteSource CircleCI orb

In the agile age of software development, speed is the name of the game. This is why CI/CD tools like CircleCI have played such a pivotal role in changing how we work; sending our software along through the pipes at a breakneck pace.

We are always asking questions such as: How fast can we get a new version out to our customers? How can we add these new features and stay on schedule? How can we do these things with as little wasted time and effort as possible?

Open source software components play an important role by providing us with the building blocks of our products. These free software components allow us to skip over the more monotonous work of writing basic features on our own by offering us tried-and-true code. This allows us to focus on our business logics instead of having to build our own frameworks and infrastructures from scratch. However, even as we enjoy the benefits of open source components, they are not without their challenges, especially when it comes to security vulnerabilities.

How to output JUnit tests through CircleCI 2.0 for expanded Insights

CircleCI provides useful information around the performance of your jobs and tests. It can tell you when you ran your last run, your median job time, queue time, and success rate, along with some graphs to help you visualize things.

Build a Clojure web app using Duct

In this blog post, we are going to build a server-side web application using Clojure and a framework called Duct. Why Duct? Most Clojure web applications are built up in a bespoke fashion using a collection of libraries picked and put together by the developer. Duct provides a modular framework that takes away some of the efforts of searching for these libraries and enables you to get a basic, server-side web application up and running faster. There are other Clojure web frameworks, but Duct has a nice mix of defaults without too much of a learning curve.

Debug your CircleCI environments using the Rookout orb

Our goal at Rookout, the rapid debugging solution, is to help developers debug quickly and effectively, even in places where it would otherwise be hard. Dynamically created staging or testing environments can have a different configuration each time they are created, which leads to unpredictable results and bugs that are impossible to reproduce. Debugging such environments is sometimes just as hard and frustrating as debugging in production. CircleCI orbs make it easy to integrate with Rookout - a solution that makes debugging in production, staging, or test environments just as easy as debugging on your local machine.

With Rookout, you can keep your CI/CD flow fresh and stable, allowing your team to keep pushing features and fixes without fear.

Designing a package manager from the ground up: an inside look at CircleCI orbs

Less than three months ago, we launched CircleCI orbs, our package management ecosystem for CircleCI configuration. In that time we have seen over 300 orbs created in just the first 10 weeks and more than 200 organizations using orbs across over 1,000 projects in tens of thousands of builds. We are also featuring more than 20 official partner orbs through our new Technology Partner Program. We’re incredibly grateful for the huge and positive response.

In this piece, I want to take a look back and share the key design decisions that went into creating and launching CircleCI orbs. If you’re using orbs today and want to understand how to get the most from them, or if you’re thinking about designing your own package management system, this post is for you.

Continuously testing React applications with Jest and Enzyme

React has taken the frontend world by storm, and for a good reason. It provides an intuitive model for building data-driven user interfaces. React enables us to write declarative components describing the user interface and provide the data needed to render these interfaces. It then efficiently updates the DOM when this data changes. Redux, on the other hand, enables managing the data that React needs to render interfaces. It offers a predictable way to structure and update the data in frontend applications and pairs quite nicely with React.

Cross-browser screenshot testing with the CircleCI Happo orb

Happo helps you build your user interface (UI) faster and with confidence. Automated screenshots taken in different browsers and across different screen sizes let you know exactly what parts of the UI change when you push a new commit. Organizations that use CircleCI can now directly integrate Happo using the Happo CircleCI orb.

What we've learned about hiring engineering managers

Over the last year, we have made some critical shifts in our understanding of what we believe makes a great engineering manager at CircleCI, and learned a lot about our needs and values as an organization along the way. We’ve changed our hiring process substantially, and through these efforts we’ve hired some fabulous people, doubling our engineering management team. Today, we want to share all these learnings with you.

Integrating container image scanning into CircleCI builds with the Twistlock orb

Developers and DevOps teams have been key drivers of container adoption. The practice of DevSecOps embeds security right into today’s modern workflows without adding unnecessary friction from the security side of the organization. That doesn’t mean security teams are left out. On the contrary: by integrating with the tools developers are already using, like CircleCI, standards set by security teams are continually applied as part of the build and deploy process.

Tips for writing your first orb

In my last post, I went over the process I went through building my first orb, and explained why it’s such a great option for those wanting to make a contribution to the open source community. In this post, I’d like to sum up the most important things I learned while writing the orb, to give some guidance to those who may want to give it a try (and I really recommend you do)!

So, ready to write an awesome and popular orb for that sweet open source contribution sauce? Keep these considerations in mind:
