RelayService
An instance-level ActivityPub actor. Used by the InferenceService and the SynchronizerService.
Usage
const { RelayService } = require('@semapps/activitypub');
module.exports = {
  mixins: [RelayService],
  settings: {
    actor: {
      username: 'relay',
      name: 'Relay actor for instance'
    }
  }
};
You must also make sure that your server has a container that accepts Application type.
This service will create an ActivityPub actor there, with the name relay.
You could put the actor in the /users container, or in a dedicated /bots container.
const containers = [{
  path: '/users',
  acceptedTypes: ['pair:Person', 'Application'], // The Application type is important
  blankNodes: ['sec:publicKey'],
  excludeFromMirror: true
}];
You also most probably want to use the option excludeFromMirror: true. It will hide prevent this container from being mirrored.
