Feature Flags

Feature flags allow us to enable and disable certain features at build time, helping us to produce specific builds for specific environments.

Workflow

All feature flags are located in suite-common/suite-config/src/features.ts. To add a new flag, start by doing the following:

1. Add your flag to the FLAGS constant and set its default value. When naming your flag, bear in mind the following conventions:
   1. Always explain what the flag is about using a comment next to it.
   2. The name of the flag should always be in capitals.
   3. The name of the flag should never contain the world enable or disable because the name should always towards an enabled state. Its value should reflect whether the feature is enabled or not.
   4. The name of the flag should never contain the word flag because it's inferred.
2. (optional) You can override the flag for each environment (web, desktop) using their specific constants.
3. Use the isFeatureFlagEnabled function from @suite-utils/features to check if the flag is enabled or not.
4. Wrap the code you wish to control in a condition checking for your flag being enabled or not.

Example

import { isFeatureFlagEnabled } from '@suite-utils/features';

const main = () => {
    alwaysRunning();

    if (isFeatureFlagEnabled('LABELING')) {
        myLabelingFeature();
    }
};

Future evolutions

• Control feature flags at runtime.
