Are you ready to amplify your Shiny applications with Google Firebase? This guide walks you through the steps to integrate Firebase for authentication effortlessly. Think of Firebase as your application’s personal bouncer—it checks on your users and grants them access based on their identity, ensuring your app remains secure while providing a smooth user experience.

What Is Firebase?

Google Firebase is a platform that provides a variety of tools and services for web and mobile app development. In this case, we will focus on its authentication features, allowing you to manage user sessions with a variety of authentication methods.

Authentication Methods

Currently, the following authentication methods are available in the Firebase package:

• Email & Password
• Email Link
• Google
• Github
• Facebook
• Twitter
• Microsoft
• Yahoo!
• Phone

How to Get Started

Follow these steps to integrate Firebase authentication into your Shiny application:

Step 1: Installation

To begin using Firebase in your Shiny application, you need to install the package. Here’s how:

• Install the stable version from CRAN:

install.packages("firebase")

• For the development version from GitHub, use:

# install.packages("remotes")

• Then:

remotes::install_github("JohnCoene/firebase")

• For the latest cutting-edge features, use:

remotes::install_github("JohnCoene/firebase@packer")

Step 2: Example Code

Now that you have installed Firebase, let’s dive into the application code. Imagine you are a conductor, and the `shinyApp` is your orchestra, each instrument (code) plays a role in creating a beautiful symphony (fully functional app).

Here’s how your code might look:

library(shiny)
library(firebase)

ui <- fluidPage(
  useFirebase(),  # Import dependencies 
  firebaseUIContainer()
)

server <- function(input, output) {
  f <- FirebaseUI$    new()$  # Instantiate
    set_providers(  # Define providers
      email = TRUE, 
      google = TRUE
    )$ 
    launch()  # Launch
}

shinyApp(ui, server)

Troubleshooting

While implementing the Firebase integration, you may run into some challenges. Here are some troubleshooting tips to help you get back on track:

• Firebase not connecting: Ensure your Firebase project settings are correctly configured. Double-check API keys and authentication methods.
• No response from providers: Verify that the providers you activated (email, Google, etc.) are supported and properly set up in your Firebase console.
• UI not displaying: Make sure you have included the necessary library calls and UI components.
