Installation and Setup

To set up the project locally, follow these steps:

Prerequisites

• Node.js and npm (Node Package Manager) installed on your machine.
• Git installed for version control.

Steps

1. Clone the repository: git clone https://github.com/imtushaarr/KrafChat-App.git & cd KrafChat-App command.

2. Install dependencies: npm install command.

3. Set up Firebase:

• - Create a Firebase project in the console.firebase.google.com
• - Enable Firestore, Authentication, and Storage in your Firebase project.
• - the google-services.json file and place it in the src/lib directory.
• - a .env file in the root of your project and add your Firebase configuration details.

4. Start the development server: npm run dev command.

5. The app should now be running on http://localhost:3000.

Detailed Component Breakdown

Authentication

User authentication is handled by Firebase Authentication. Users can sign up, log in, and manage their session. The Login component handles the UI for these processes, while the Firebase API manages the backend logic.

Chat Functionality

The core of the application is the chat functionality. Users can start conversations, send text messages, and view chat history. The chat data is stored in Firestore, and the UI is updated in real-time using Firebase’s snapshot listeners.

User Blocking

Users have the ability to block or unblock other users. This is managed via Zustand for state management and Firestore for persistence. The Detail component handles the user interface for blocking and other settings.

Media Sharing

The Firebase configuration is essential for connecting your app to Firebase services. This includes setting up Firestore for the database, enabling Firebase Authentication for user management, and configuring Firebase Storage for media uploads.

Media Sharing

VITE_FIREBASE_API_KEY=your_api_key
VITE_FIREBASE_AUTH_DOMAIN=your_auth_domain
VITE_FIREBASE_PROJECT_ID=your_project_id
VITE_FIREBASE_STORAGE_BUCKET=your_storage_bucket
VITE_FIREBASE_MESSAGING_SENDER_ID=your_messaging_sender_id
VITE_FIREBASE_APP_ID=your_app_id

Make sure to replace the placeholders with your actual Firebase project details.

State Management with Zustand

Zustand is used for managing the global state of the application, including user data and chat states. It provides a simple and lightweight alternative to more complex state management libraries like Redux.

Example Zustand Store for Chat

import { create } from 'zustand';
export const useChatStore = create((set) => ({
chatId: null,
user: null, isCurrentUserBlocked: false,
isReceiverBlocked: false,
// other state and actions... }));

This store handles the state of the current chat, including whether the current user or the recipient is blocked.

Styling

The application is styled using standard CSS. Each component has its own CSS file, making it easy to manage styles and ensure that the UI is consistent across the app.

Global Styles

The index.css file contains global styles, including font settings, color variables, and default element styles. Component-specific styles are contained within their respective CSS files.

Security Considerations

• Authentication: Ensure that only authenticated users can access the chat functionalities.
• Data Validation: Validate and sanitize user inputs to prevent XSS and other attacks.
• Firestore Rules: Implement Firestore security rules to control who can read or write to your database.
• Environment Variables: Store sensitive information like API keys in environment variables and never commit them to Git.

Conclusion

The KrafChat App is a robust, real-time chat application designed with scalability and user experience in mind. By leveraging modern tools like React, Zustand, and Firebase, the app offers a seamless and responsive chat experience. This documentation should provide a comprehensive overview of the project and guide you through the setup, development, and deployment processes.
