super({ name: 'First initiable' })
}

console.log('%%%%%% First create') // eslint-disable-line no-console
}

protected async _destroyFn(): Promise {
console.log('%%%%%% First destroy') // eslint-disable-line no-console
}
}

// app.ts
import { AppFlow } from '@beecode/msh-node-app'

export class App extends AppFlow {
public constructor() {
super(new FirstInitiable(), [new SecondInitiable(), new ThirdInitiable()])
}
}


// index.ts
import { LogLevelType } from '@beecode/msh-node-log'
import { ConsoleLogger } from '@beecode/msh-node-log/lib/console-logger'

import { NodeAppLogger } from '@beecode/msh-node-app/lib/util/logger'

import { appStarterFactory } from '@beecode/msh-node-app'
import { App } from './app'

NodeAppLogger(new ConsoleLogger({ logLevel: LogLevelType.DEBUG }))
