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 your applications' source code. You...

Today, we are announcing an important addition to the Heroku Platform API: The /apps/:app/builds endpoint. This endpoint exposes the Heroku slug compilation process as a simple API primitive. You can use the endpoint to turn any publicly hosted source-tarball into a slug running on a Heroku app in seconds.

Here’s output from a Go program that invokes the new endpoint:

$ ./build -app limitless-fjord-5604 -archive ......... -----> Node.js app detected -----> Requested node range: 0.10.x -----> Resolved node version: 0.10.28 -----> Downloading and installing node … $ curl

Today we’re open sourcing the toolchain Heroku uses to design, document, and consume our HTTP APIs. We hope this shows how Heroku thinks about APIs and gives you new tools to create your own.

This toolchain includes:

  • An HTTP API design guide, describing how we structure both internal and public-facing APIs and document them using the JSON Schema standard.

  • A tool for working with JSON schemas and using them to generate API documentation.

  • Ruby and Go client code generators for APIs with JSON schemas.

Here’s some more information about these things, how we use them at Heroku, and an explanation of how you can try them yourself.

Today, we’re happy to announce General Availability of the Heroku Platform API. Heroku is a platform built by developers, for developers. As developers, we understand the utility of APIs and the power APIs give to speed up and script error-prone manual processes or to combine other services with Heroku into new and exciting products. With the Platform API, you now have a fully documented and supported way to instrument and automate Heroku.

Platform API

Designing and implementing this API has been an important process for Heroku internally: It has forced us rethink how different platform components are factored and how they should be exposed in a clean and coherent manner. We are already using the...
