#Feature Manager

Use the feature manager to control which Wallet API v2 features are enabled at service startup. This reduces complexity and the risk of misconfigurations.

#Feature Types

The feature manager offers two types: Base and Optional.

#Base Features

Base features are always enabled and provide critical functionality expected to be available by default. For the Wallet API v2, the core wallet-service is a base feature.

#Optional Features

Optional features can be enabled or disabled based on your requirements.

1. Enabled by default: work without additional configuration.
2. Disabled by default: must be explicitly enabled in _features.conf, and may require their own configuration file.

#How the Feature Manager Works

1. Initialisation with Feature Catalogs: the service is passed its feature catalog on startup.
2. Determination of Active Features: the initialiser resolves which features are explicitly enabled or disabled, and the default state of the rest.
3. Loading Configurations: only the configurations for base features and explicitly enabled optional features are loaded.

#Feature Configuration

Configure features by editing _features.conf, as explained in Features.
