App configuration

Separating configuration from code is an established best practice and the third factor of The Twelve-Factor App methodology. It lets you:

  • Update configuration instantly without a code update, build, deployment, app release or service restart

  • Safely empower nontechnical teammates to view and change configuration themselves, saving developers time

  • Optimize configuration with manual tuning, A/B testing and machine learning

  • Unify configuration across different codebases, like frontend and backend, into a single source of truth

  • Make your code cleaner, smaller and more flexible

  • Reduce engineering complexity and improve system reliability by separating the concerns of code and configuration
