What do you have running on Heroku?

We’re running just about everything on Heroku, including our Bonobos.com website, cross-app messaging services, an API for our ERP, as well as some internal tools. The only pieces that are not on Heroku are the Data Science and ERP components. We’re also using Desk.com for customer service queuing.

Walk us through your stack

We use a mix of Backbone and React in terms of JavaScript frameworks on the front end. Some of our legacy work is in Backbone and our newer...


At Heroku, we're always working towards increased operational stability with the services we offer. As we recently launched the beta of Apache Kafka on Heroku, we've been running a number of clusters on behalf of our beta customers.

Over the course of the beta, we have thoroughly exercised Kafka through a wide range of cases, which is an important part of bringing a fast-moving open-source project to market as a managed service. This breadth of exposure led us to the discovery of a memory leak in Kafka, having a bit of an adventure debugging it, and then contributing a patch to the Apache Kafka community to fix it.

Issue Discovery

For the most part, we’ve seen very few issues...


So you want to build an app with React? "Getting started" is easy… and then what?

React is a library for building user interfaces, which comprise only one part of an app. Deciding on all the other parts — styles, routers, npm modules, ES6 code, bundling and more — and then figuring out how to use them is a drain on developers. This has become known as javascript fatigue. Despite this complexity, usage of React continues to grow.

The community answers this challenge by sharing boilerplates. These boilerplates reveal the profusion of architectural choices developers must make. That official "Getting Started" seems so far away from the reality of an operational app.


Today we're announcing two new features that will help you better manage and run apps on Heroku: Threshold Alerting and Hobby dyno metrics. Threshold Alerting provides the ability to set notification thresholds for key performance and health indicators of your app. We’ve also extended basic Application Metrics to Hobby dynos to provide basic health monitoring and application guidance. Together these features allow you to stay focused on building functionality by letting the platform handle your app monitoring.

Threshold Alerting

There are many ways to measure the health of an application. The new alerting feature focuses on what is most important to the end users of your app:...


Redis might sound like it’s just a key/value store, but its versatility makes it a valuable Swiss Army knife for your application. Caching, queueing, geolocation, and more: Redis does it all. We’ve built (and helped our customers build) a lot of apps around Redis over the years, so we wanted to share a few tips that will ensure you get the most out of Redis, whether you’re running it on your own box or using the Heroku Redis add-on.

Use a Connection Pooler

By using a connection pooler, you'll reduce the connection overhead and therefore speed up operations while reducing the number of connections you use.

Most Redis libraries will provide you with a specific connection pooler...
