Introducing the app.json Application Manifest

Developers want to spend less time setting up applications and start working with the code sooner. Setting up applications is error-prone, time consuming and interruptive to the development flow. Often, there are several steps to go from your code or other samples and templates that you find in repositories online, to a running application that you can continue to work on.

Today, we are excited to introduce the app.json manifest. app.json enables developers to define their applications' details, setup configurations and runtime environments in a structured way. Instead of providing step-by-step instructions, you can now add app.json files to …

Auto-generating a Go API client for Heroku

Editor's note: This is a cross post from Blake Gentry, an engineer at Heroku.

This is a post about the recently announced Heroku Platform API JSON Schema and how I used that schema to write an auto-generated Go client for the API.

Heroku's API team has spent a large part of the past year designing a new version of the platform API. While this is the 3rd incarnation of the API, neither of the two previous versions were publicly documented. In fact, the only documentation on the old APIs that was ever published is the source code of the …

Helios – open source framework for mobile

Heroku has a strong tradition with open source projects. Engineers have dedicated countless hours to the projects that developers count on every day. Open Source Software is in our DNA.

Speaking personally, I’m passionate about building tools like AFNetworking and cupertino, in order to help developers build insanely great experiences for mobile devices. It’s with great pleasure that I introduce something new I’ve been working on:

Helios is an open-source framework that provides essential back-end services for iOS apps. This includes data synchronization, push notifications, in-app purchases, and passbook integration. It allows developers to get a client-server app up-and-running …

Waza 2013: How Ecosystems Build Mastery

When we think of the concept of Waza (技) or "art and technique," it's easy to get caught up in the idea of individual mastery. It's true that works of art are often created by those with great skill, but acquiring that skill is neither solitary nor static. Generations of masters contribute to a canon and it is in that spirit that we built the Heroku platform and the Waza event. This year's Waza was no exception.

On February 28th, more than 900 attendees participated in Waza including Ruby founder Yukihiro "Matz" Matsumoto, Django co-creator Jacob Kaplan-Moss and Codeacademy’s …

Sunsetting the Argent Aspen Stack

Heroku's Aspen stack is the product that launched our company and inspired a new class of cloud services. After much deliberation and careful thought, we have decided to sunset the Aspen stack by Thursday, November 22nd. We ask application owners still using Aspen to migrate to Cedar.

Since Aspen's launch over four years ago, Rails has seen the introduction of Bundler for dependency management, the asset pipeline, and a major framework re-write. Heroku has also grown, and with the introduction of the Cedar stack, we have moved beyond our humble origins and have become a true polyglot platform…

Sunsetting and Deprecation at Heroku

Software erosion is what happens to your app without your knowledge or consent: it was working at one point, and then doesn't work anymore. When this happens you have to invest energy diagnosing and resolving the problem. Over a year ago Heroku's CTO, Adam Wiggins, first wrote about erosion-resistance on Heroku. Part of erosion-resistance is communication, and knowing what to expect moving into the future. This post will clarify what we mean by erosion-resistance, and help you understand what to expect when one of our features is deprecated or is sunset.

Erosion Resistance

Erosion-resistance means that your apps are protected …

Multiple Ruby Version Support on Heroku

Maximizing parity between development and production environments is a best practice for minimizing surprises at deployment time. The version of language VM you're using is no exception. One approach to this is to specify it using the same dependency management tool used to specify the versions of libraries your app uses. Clojure uses this technique with Leinigen, Scala with SBT, and Node.js with NPM. In each case, Heroku reads the dependency file during slug compile and uses the version of the language that you specify.

Today, we're pleased to announce that we've added support for specifying a …

Java Hackathon

This weekend, join us for a Java Hackathon at the Heroku office in San Francisco.

We've decided to kick things off with a contest. To enter, build a creative and/or useful application that enables or manages interactions with customers or potential customers via social media channels. It can be any social media channel, and your app will be judged on how well it fits the contest criteria as well as the quality of your concept and implementation.

The overall winner will receive a $500 Amazon gift card and a $500 Heroku credit. Two runners up will win a $100 Heroku …

The Next Level: Heroku Will Be Acquired By Salesforce

What if enterprise apps were built the way you’d build an agile Ruby app? What if they were a pleasure to work with, deploy, and manage? What if big companies could adopt the philosophies of Heroku and the Ruby community? What if your company actually preferred you use Heroku to build apps?

That’s the next level for Heroku. That’s where we want to go, so we’ve made a decision we’re excited to share: we have signed a definitive agreement to be acquired by salesforce.com. We expect the deal to close by January 31st.

Why Salesforce.com?

Salesforce.com is the original cloud …

Want a HUG? Join Us at the Heroku Users Group Meeting

It’s no secret that Heroku’s getting pretty big. Heck, we advertise the number of apps running on the platform right there on the homepage (over 88,000, when I last looked). We’ve got tens of thousands of developers, and you all have been doing some amazing work — the success stories we’ve posted are only the tip of the iceberg. With that in mind, we thought it was high time we started to get all of you together. So, on November 3rd, we’re going to hold the first official Heroku Users Group meeting. Join us at our office at 7pm to …
