// Init Journaly as a observer platform for using as a message broker
const journaly = Journaly.newJournaly() as SubjectObserver<any>;

// config read database
read = new ServiceHandler(new PersistenceInfo({}, journaly), {
  test: new TestService(),
});

// config write database
write = new MongoDB(
  new PersistenceInfo(
    {
      database: 'write',
      host: process.env.MONGO_HOST || 'localhost',
      port: process.env.MONGO_PORT,
    },
    journaly
  )
);

// init Flexible Persistence handler with write and read databases
const handler = new Handler(write, read);

// sample object
const obj = {};
obj['test'] = 'test';

// create an event to create an object
const persistencePromise = await handler.addEvent(
  new Event({ operation: Operation.create, name: 'object', content: obj })
);

// prints create event
console.log(persistencePromise);
