Configs

Each feature can declare that it can be configured using the Config entity. We can import the Config entity and use in the feature declaration.

export default new Feature({
  id: 'myFeature',
  api: {
    someConfig: new Config<{ mandatoryKey: string; optionalKey?: string }>({ mandatoryKey: 'value' }),
  },
});

The Config entity defined the interface of the config and requires a default value.

In the setup phase of the feature, in any environment, we now can access the config as follows:

f.setup(env, ({ someConfig }) => {
  console.log(someConfig);
});

If no other config is provided, the following code will output

{ mandatoryKey: 'value' }
