OpenTelemetry Basics on Heroku Fir

Heroku recently made the next generation platform – Fir – generally available. Fir builds on the strengths of the Cedar generation while introducing a new modern era of developer experience. Fir leverages modern cloud-native technologies to provide a seamless and performant platform.

One of the goals we set out to achieve with Fir is to modernize our platform’s observability architecture. Applications being written today are becoming increasingly more distributed and complex in nature. With this increase in complexity, the need for good observability becomes critical. With solid observability practices in place, it becomes possible to gain deep insights into the internal…

Deploying a Simple Go/Gin Application on Heroku

The speed and efficiency of the Go programming language make it popular for backend development. Combine Go with the Gin framework —which offers a fast and minimalistic approach to building web applications—and developers can easily create high-performance APIs and web services. Whether you’re working on a personal project or building a production-ready application, Go and Gin make for an attractive stack perfectly suited for lightweight, scalable web development.

Creating a Go/Gin application might seem straightforward: You write a few routes, connect a database, and spin up a local server. But when it comes to deploying your app, things can get tricky.…

SignalR Scalability: Scaling Real-Time SignalR Applications on Heroku

SignalR makes it easy to add real-time functionality to .NET web applications—things like live chat, instant notifications, or interactive dashboards. But what happens when your app starts to grow? A single server can only take you so far. At some point, you’ll need to take advantage of SignalR scaling features to scale out your app.
In this post, we’ll walk through what it takes to scale a SignalR app to run across multiple servers. We’ll start with the basics, then show you how to use Redis as a SignalR backplane and enable sticky sessions to keep WebSocket connections stable. And we’ll…

Heroku Open Sources the Twelve-Factor App Definition

Today, we are excited to announce Twelve-Factor is now an open source project. This is a special moment in the journey of Twelve-Factor over the years. Published over a decade ago by Heroku co-founder Adam Wiggins to codify the best practices for writing SaaS apps , the ideas espoused on the Twelve-Factor App website inspired many generations of software engineers and the principles we take for granted in modern application development.

Open sourcing the 12-Factor App is an important milestone to take the industry forward and codify best practices for the future. As the modern app architecture reflected in the…

Testing a React App in Chrome with Heroku CI

When building web applications, unit testing your individual components is certainly important. However, end-to-end testing provides assurance that the final user experience of your components chained together matches the expected behavior. Testing web application behavior locally in your browser can be helpful, but this approach isn’t efficient or reliable, especially as your application grows more complex.

Ideally, end-to-end tests in your browser are automated and integrated into your CI pipeline. Every time you commit a code change, your tests will run. Passing tests gives you the confidence that the application — as your end users experience it —…

Electric’s Advice During Uncertain Times: Invest in Your Culture

Some say that the only constant in life is change. That may be true, but often what’s more important than the change itself is how we react. We all go through life trying to manage change (albeit with varying degrees of success), so we can better cope with it, learn from it, and adapt. Like individuals, organizations can learn the same “life skill,” so that change is not only less disruptive, but it also becomes a measure of organizational health that can lead to success.

Sometimes, it takes a pandemic

Times of sudden change, like…

From Project to Productionized with Python

This blog post is based on From Project to Productionized , a talk given at PyCon 2020 at the height of the COVID-19 pandemic.

“Do I Qualify?” And Other Questions Imposters Must Ask Themselves

A word of caution from a former AP Computer Science teacher who, with zero real-world programming experience, quit her dependable teaching gig to become a software engineer: Imposter Syndrome is never late to class.

When we grow competent in our craft, yet continue to feel unqualified for our role, that feeling is known as "Imposter Syndrome." The syndrome was with me before I started, it’s here with me now, and it will probably be with me for a long time to come.

If you’ve experienced it too, then reading that last sentence may leave you…
