Study Notes
Firebase Overview
- Firebase is a client-side app development platform developed by Google
- It integrates with many Google tools, like ads
- It's a collection of around 20 products
- Products are categorized into build and run categories
Firebase Build Category
- Managed Infrastructure: Protects backend resources and verifies traffic origins
- App Check: Protects backend from abuse and ensures only authorized users access
- Hosting: Provides secure, global hosting for static and dynamic web apps
- Authentication: Simplifies user login and onboarding using built-in UI and security methods (email/password, social logins, etc.)
- Firestore (NoSQL): Flexible database with scalability and cloud hosting supporting real-time updates, offline use, structured data with documents and collections
- Real-time Database: Optimized for simpler use cases needing fast real-time synchronization across devices, using JSON tree structure
- Cloud Storage: Provides secure and robust file storage synchronizing between app and cloud
- Cloud Messaging: Sends targeted push notifications for user engagement using unique tokens for targeting
- In-app Messaging: Displays contextual messages within the app, such as prompts, based on user actions or app state
Firebase Run Category
- Crashlytics: Real-time crash reporting tool to identify and fix stability issues in the app
- Google Analytics: Free tool to track app usage, user behavior, and engagement
- Cloud Messaging: For sending targeted push notifications
- In-app Messaging: Displays contextual messages in-app based on user actions or app state
- Remote Config:Allows for updating app behavior without code updates (new versions).
- A/B Testing: Compares different app variations to determine better performing ones.
Firebase Console
- Google provides various "consoles" to manage different aspects of Firebase, including the main Firebase console
- Consoles are webpages for controlling various settings
- Firebase also has a dedicated console to manage the products
- There is a section for viewing analytics in the console
Analytics
- Real-time data updates on device usage, demographics and app engagement data once every 24 hours
- Provides a dashboard allowing developers to view this information
Firebase Storage
- Provides cloud-based storage for files accessible by app, handling networking and syncing
Firebase Setup and Use Examples
- Examples of adding Firebase to Android apps to handle authentication, data access, storage and use of existing SDKs.
Firebase Database (Realtime Database & Firestore)
- RealtimeDatabase: A JSON tree-based, real-time, cloud database
- Firestore: A NoSQL, document-based, scalable database well-suited for various data structures, with query capabilities.
- Setup and use examples for connecting and interacting with these databases provided, including adding data and retrieving it within the app.
