As the modern app architecture reflected in the 12-Factors became mainstream, new technologies and ideas emerged, and we needed to bring more voices and experiences to the discussion.

Today we're excited to announce that we've open sourced oclif, a framework for building command line interfaces.

We built oclif to serve as the common foundation for both the Heroku and Salesforce CLIs and to abstract away the common struggles. The framework is now available to any developer for building CLIs large or small. oclif makes building CLIs more accessible by providing you with the patterns and tools to scaffold a working command line interface. It provides a structure for simple to advanced CLIs, including documentation, testing, and plugins for adding new commands.

With oclif you can get up and running with your command line interface quickly, and focus on the...
