Verify that needed system libraries, like curl or ImageMagick, are available.

Make sure that app-specific libraries are available.

This principle maintains that you should never rely on the implicit existence of system-wide packages. Dependencies “Explicitly declare and isolate dependencies” This makes version control almost impossible to understand and versions will get tangled up, resulting in non-value-added work. Avoid housing multiple applications in the same repository.

Your code base should have a logical version control system that’s easy to understand.Įvery deployment should have its own code repository that can be deployed to multiple environments. Codebase “One codebase tracked in revision control, many deploys”

The group points to two inspirational sources, Patterns of Enterprise Application Architecture and Refactoring, both by professional developer Martin Fowler.Īnd now, I’ll introduce each of the 12 factors.

To raise awareness of systemic problems they’ve observed in modern app development.

The relationship and collaboration between codebase developers.

The dynamics that occur as an app grows organically.Ideal practices to support app development.This group considers the methodology a triangulation of: These programmers have developed and deployed hundreds of apps wrote this methodology, drawing on their experience of seeing SaaS apps “in the wild”. In 2012, programmers at Heroku debuted the 12-Factor app methodology. In this article, I’ll introduce the 12-factor app methodology and offer a high-level summary of its principles. The 12 factors is an approach that helps programmers write modern apps in a declarative way, using clear contracts deployed via cloud. To handle this dissonance, the 12-Factor App methodology has emerged. Writing application code predates most cloud solutions-solutions that most application programmers write specifically for these days.
