Dynamic Config

What is a Dynamic Config?​

Dynamic config is a tool that replaces hard-coded values in your application with configuration parameters defined on the server. These configuration parameters can cover a wide range of properties in both your client-side and server-side code, such as button colors, feature toggles, or ranking configurations. This allows you to control the behavior of your application dynamically and in near real-time.

However, it's important to note that the configuration will not automatically update on its own. You will need to manually refresh the config by calling getConfig again to apply any updates in your code.

When to Use a Dynamic Config​

Dynamic config is especially useful when you want to make your server-side code the source of truth for application properties, allowing you to modify configurations without redeploying code. Many companies, like Spotify, leverage Remote Configuration to dynamically update client or backend service properties.

Examples of Use Cases:​

  • Feature Toggles: Dynamically enable or disable features without code changes.
  • A/B Testing: Vary configurations across user segments to measure impact.
  • Real-Time Updates: Instantly adjust app properties like UI elements or service thresholds.
