App Check

You can integrate Firebase App Check with your app to protect your backend resources from abuse, such as billing fraud or phishing. Firebase App Check works alongside other Firebase services, such as Firebase Authentication, to help secure your backend resources.

FireCMS provides a simple way to integrate Firebase App Check with your app.

Remember to add the domain where you will be deploying your app to the list of allowed domains in AppCheck provider configuration.

For self-hosted versions, you can enable Firebase App Check in your app by providing the options and firebaseApp props in the useAppCheck hook.

The useAppCheck hook is used to initialize Firebase App Check and monitor its status. It handles the asynchronous initialization process, provides loading state, and captures any errors that may occur during initialization.

Parameters

• firebaseApp (optional): An instance of FirebaseApp to use for App Check initialization.
• options (optional): Configuration options for App Check.
  • provider: The provider you want to use.
  • isTokenAutoRefreshEnabled: Whether to automatically refresh the token.
  • debugToken: A debug token to use.
  • forceRefresh: Whether to force a token refresh.

Return Value

Returns an object that includes:

• loading: A boolean indicating whether the initialization is in progress.
• appCheckVerified (optional): A boolean indicating whether the app has been verified by App Check.
• error (optional): Any error encountered during the initialization process.

Example

import {useAppCheck} from "@firecms/firebase";
import {ReCaptchaEnterpriseProvider} from "@firebase/app-check";

const {
    loading,
    error,
    appCheckVerified
} = useAppCheck({
    options: {
        provider: new ReCaptchaEnterpriseProvider(process.env.VITE_RECAPTCHA_SITE_KEY as string),
        isTokenAutoRefreshEnabled: true,
    }
});

Providers

The provider property is required and should be an instance of a Firebase AppCheck provider. You can use one of the following providers:

ReCaptchaEnterpriseProvider

In order to set up the ReCaptchaEnterpriseProvider, you need to create a new reCAPTCHA Enterprise site key. Follow the instructions in the Firebase documentation.

Make sure you have added the domain app.firecms.co to the list of allowed domains in the reCAPTCHA Enterprise console.

import {useAppCheck} from "@firecms/firebase";
import {ReCaptchaEnterpriseProvider} from "@firebase/app-check";

const {
    loading,
    error,
    appCheckVerified
} = useAppCheck({
    options: {
        provider: new ReCaptchaEnterpriseProvider("your-site-key"),
        isTokenAutoRefreshEnabled: true,
    }
});

ReCaptchaV3Provider

In order to set up the ReCaptchaV3Provider, you need to create a new reCAPTCHA v3 site key. Follow the instructions in the Firebase documentation.

import {useAppCheck} from "@firecms/firebase";
import {ReCaptchaV3Provider} from "@firebase/app-check";

const {
    loading,
    error,
    appCheckVerified
} = useAppCheck({
    options: {
        provider: new ReCaptchaV3Provider("your-site-key")
        isTokenAutoRefreshEnabled: true,
    }
});

Custom provider

You can also create a custom provider by implementing the AppCheckProvider interface.
