# Configuration with bluerain.js

All projects created by the BlueRain CLI have a `bluerain.ts` (or `bluerain.js`) file. This file serves as a manifest for a BlueRain project. This is where you import all your plugins, hooks, components and configurations. 

Practically, this file only exports an object that has props of `BlueRainApp` component. So if you're building or compiling the project without BlueRain CLI, it possible to not have a `bluerain.ts` (or `bluerain.js`) file at all and just use any code structure that suits your project.
