Configuring Default Values for Feature Gates in Statsig

When working with Statsig feature gates, it's crucial to set default values to ensure your application behaves as expected, even if the initialization fails. By default, feature gates return false. However, you can configure them to return true if needed.

Setting Default Values

To ensure a feature is enabled by default, you can use the following approach:

// Check if the feature gate is active
if (!useGate('my_killswitch')) { 
  // Execute the feature if the gate is not active
  showFeature(); 
}

In this example, the useGate function checks the status of the feature gate named my_killswitch. If the gate is not active (returns false), the showFeature function is called, allowing the feature to be displayed.

Understanding Feature Gate Behavior

Feature gates in Statsig are designed to be boolean, defaulting to false. If you want a feature to be enabled by default, consider naming your gate in a way that reflects its intended behavior. For instance, instead of naming it launch_cool_new_feature, you might name it block_cool_new_feature. This way, your code can be structured as follows:

// Check if the feature is blocked
if (statsig.checkGate('block_cool_new_feature')) { 
  // Do not show the new feature
} else { 
  // Show the new feature
}

By using this naming convention, you can easily manage the visibility of features based on the gate's status.

Conclusion

Setting default values for feature gates is essential for maintaining control over feature visibility in your application. By understanding how to configure these gates effectively, you can ensure a smooth user experience, even in cases where initialization may fail.
