---

Makerkit stores your project configuration in a Typescript file named `configuration.ts`, in which we store **non-secret** data needed in the client-side bundles of your project.

## What is stored in the configuration file?

In this configuration file, we store data that is safe to be exposed in the client-side bundles of your project.

The configuration file contains the following data:

```tsx
import { LayoutStyle } from '~/core/layout-style';
import { GoogleAuthProvider } from 'firebase/auth';

enum Themes {
  Light = 'light',
  Dark = 'dark',
}

const configuration = {
  site: {
    name: 'Awesomely - Your SaaS Title',
    description: 'Your SaaS Description',
    themeColor: '#ffffff',
    themeColorDark: '#0a0a0a',
    siteUrl: process.env.NEXT_PUBLIC_SITE_URL as string,
    siteName: 'Awesomely',

  },
  auth: {
    // Enable MFA. You must upgrade to GCP Identity Platform to use it.
    // see: https://cloud.google.com/identity-platform/docs/product-comparison
    enableMultiFactorAuth: true,
    // When enabled, users will be required to verify their email address
    // before being able to access the app

          },
        ],
      },
    ],
  },
};

export default configuration;
```

## How should I store my secrets?

You should store your secrets in your **non public** environment variables, and ideally set up from your CI or Hosting Provider (such as Vercel).

Never add secrets to the configuration file, as it is exposed in the client-side bundles of your project.

Please refer to the Next.js official documentation on how to best store your secrets.
