Custom CMSApp

info

You only need to build a custom FireCMS app if you need a high degree of customization, like custom layouts, data source or storage source adaptations or special navigation or routing. Most use-cases are covered by the basic set-up. If you are getting started with FireCMS, it is recommended to follow the quickstart

FireCMS was originally developed to create Firebase/Firestore-based CMS apps with very little effort. We offer sensible defaults and multiple customization options and callbacks.

The simpler way to use FireCMS is using the component FirebaseCMSApp, which is in charge of navigation, initialising Firebase auth, storage and a Firestore datasource.

But there are a few situations where you may want to have more control and build your app using the same components that we use internally.

In that case you will want to use FireCMS as your main component, and inject all your dependencies.

In the process of having a cleaner code, all the code related to Firebase has been isolated into 3 components, one for authentication (auth delegate), one for the data source and one for storage. These components are abstracted away behind their respective interfaces. This means you can replace any of those services with your custom implementation!

For this reason we expose many of the components used internally, so you can use them in your app and combine them with your code

Some top-level components that you will find useful (same ones as used by FirebaseCMSApp):

You will also be responsible for initialising your MUI5 theme and your react-router Router

Example custom app

Scaffold,
SideDialogs,
SnackbarProvider,
useBuildModeController,

useFirebaseStorageSource,
useFirestoreDataSource,

useValidateAuthenticator
} from "firecms";

import { firebaseConfig } from "../firebase_config";

const DEFAULT_SIGN_IN_OPTIONS = [
