Building a Chat Application With Svelte and Firebase:

Building a chat application with Svelte & Firebase can be an exciting project for web developers looking to build real-time applications. The four main steps involved in building this application are setting up the project, Firebase configuration, Svelte-Firebase integration, & Google authentication implementation, followed by Firestore integration for chat.

Step 1: Setting Up The Project:

The first step in building our chat application is setting up the project. This involves developing a new Svelte app using the Svelte template & installing Firebase dependencies using npm or yarn. Once the Svelte app is set up, we can move to the next step, which is Firebase configuration.

Step 2: Firebase Configuration:

Firebase configuration involves creating a Firebase project in the Firebase console & configuring Firebase authentication for our Svelte app. We can build a new Firebase project & then configure Firebase authentication by enabling Google authentication & configuring the essential settings.

Step 3: Svelte-Firebase Integration:

The third step is Svelte-Firebase integration, which involves installing the necessary Firebase packages & configuring Firebase in our Svelte app. We can install the Firebase packages using npm or yarn & then initialize Firebase in our app by supplying the necessary configuration options.

Step 4:  Google Authentication Implementation:

The fourth step is implementing Google authentication in our chat application. This involves building a Google authentication button in our app and then handling the authentication flow operating Firebase authentication. Once the user is authenticated, we can then proceed to the final step, which is Firestore integration for chat.

Step 5: Firestore Integration for Chat:

Firestore integration for chat involves creating a Firestore supply for our chat messages & then using Firestore real-time updates to show new chat messages in real-time. We can also execute features such as message input & message deletion using Firestore APIs.
