// Meant to be done at require time
const Hebo = require('hebo');
const libraryAggregate = require('./path/to/my/libraryAggregate');
const bookAggregate = require('./path/to/my/bookAggregate');

const hebo = new Hebo({
    aggregates: {
      library: libraryAggregate,
      book: bookAggregate,
    }
})

// ... and then do this at runtime:
const { getProjection, runCommand, updateSnapshot } = hebo.connect({
    eventRepository,
    snapshotRepository,
    notificationHandler,
    authorizer,
    user,
});

await runCommand('createLibrary', 1234);
await runCommand('setLibraryName', 1234, 'North Branch');

const library = getProjection('library', 1234);

await updateSnapshot('library', 1234);
