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 your applications' source code. You...

Heroku Scheduler Add-on Now Available

Today we're happy to announce the availability of Heroku Scheduler. Scheduler is an add-on for running administrative or maintenance tasks, or jobs, at scheduled time intervals.
