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.

important

Remember to add the domain app.firecms.co to the list of allowed domains in AppCheck provider configuration.

note

This feature is requires a Plus or Pro plan.

You can enable Firebase App Check in your app directly in the project settings in the FireCMS Cloud console, or by providing the appCheck prop in your app configuration.

By implementing it in code, you can have more control over the configuration and the provider you want to use, including custom providers.

You can define some options:

• 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.

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.

important

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

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

const appConfig: FireCMSAppConfig = {

    version: "1",

    appCheck: {
        provider: new ReCaptchaEnterpriseProvider("your-site-key")
    },
}

export default appConfig;

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

const appConfig: FireCMSAppConfig = {

    version: "1",

    appCheck: {
        provider: new ReCaptchaV3Provider("your-site-key")
    },
}

export default appConfig;

Custom provider

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

Check your configuration

FireCMS Cloud can share dependencies with your uploaded app. It is important than your app and FireCMS Cloud use the same version of Firebase App Check. In order to do so, make sure, in your vite.config.ts, you are using the shared dependency provided by FireCMS. You need to have the dependency @firebase/app-check in your vite.config.ts. Federation plugin shared configuration.

This is a sample configuration:

import { defineConfig } from "vite"
import react from "@vitejs/plugin-react"
import federation from "@originjs/vite-plugin-federation"

// https://vitejs.dev/config/
export default defineConfig({
    esbuild: {
        logOverride: { "this-is-undefined-in-esm": "silent" }
    },
    plugins: [
        react(),
        federation({
            name: "remote_app",
            filename: "remoteEntry.js",
            exposes: {
                "./config": "./src/index"
            },
            shared: [
                "react",
                "react-dom",
                "@firecms/cloud",
                "@firecms/core",
                "@firecms/firebase",
                "@firecms/ui",
                "@firebase/firestore",
                "@firebase/app",
                "@firebase/functions",
                "@firebase/auth",
                "@firebase/storage",
                "@firebase/analytics",
                "@firebase/remote-config",
                "@firebase/app-check" // Add this line
            ]
        })
    ],
    build: {
        modulePreload: false,
        minify: false,
        target: "ESNEXT",
        cssCodeSplit: false,
    }
});
