Task Assigment Whatsapp API PHP Laravel Assignment (Make WhatsApp API server (whatsapp api clone):

To develop a WhatsApp-like chat API server using Laravel 8, PHP 8.0, and WebSockets, follow these steps to build and document essential chat functionalities. Here’s a structured approach:

1. Setting up the Environment • Install Laravel: Install a Laravel 8 project. • Install WebSocket Server: Use a WebSocket library like beyondcode/laravel-websockets to manage real-time messaging. • Database: Configure your RDBMS (MySQL, PostgreSQL, etc.) to set up tables for storing chatrooms, messages, and users.
2. Database Schema Tables: • Users: id, name, email, created_at, updated_at • Chatrooms: id, name, max_members, created_at, updated_at • UserChatroom (pivot table for many-to-many relationship): user_id, chatroom_id • Messages: id, user_id, chatroom_id, message, attachment_path, created_at
3. API Development
4. Create Chatroom o Endpoint: POST /api/chatrooms o Action: Create a new chatroom with a maximum member limit. o Body: { "name": "string", "max_members": integer } o Constraints: Ensure chatroom names are unique.
5. List Chatrooms o Endpoint: GET /api/chatrooms o Action: Retrieve a list of available chatrooms. o Response: Return all chatrooms with current and max member counts.
6. Enter Chatroom o Endpoint: POST /api/chatrooms/{id}/enter o Action: Add the user to a chatroom if it has not reached the max member limit. o Logic: Verify that the user isn't already a member and that the max member limit hasn’t been reached.
7. Leave Chatroom o Endpoint: POST /api/chatrooms/{id}/leave o Action: Remove the user from the chatroom. o Logic: Check if the user is a member before removing them.
8. Send Message o Endpoint: POST /api/chatrooms/{id}/messages o Action: Send a text or attachment message. o Body: { "message": "string", "attachment": "file" } o Storage: Store attachments in a root/picture or root/video directory based on the file type.
9. List Messages o Endpoint: GET /api/chatrooms/{id}/messages o Action: Retrieve all messages for a chatroom, paginated.
10. WebSocket Integration • WebSocket Channels: Each chatroom will have its WebSocket channel (e.g., chatroom.{id}). • Event Broadcasting: Use Laravel’s broadcasting capabilities for real-time updates when a new message is sent. • Presence Channels: Track users entering and leaving chatrooms to update members in real-time.
11. API Documentation • Use Swagger or Postman collections to document endpoints, parameters, responses, and possible error codes. Provide a guide on how to use each API.
12. Deployment • Deploy the Laravel API server on a hosting service like DigitalOcean, AWS, or Laravel Vapor. • Set up a WebSocket server to ensure real-time messaging functionality is live. This setup ensures a modular, scalable, and maintainable structure by separating user, chatroom, and message management responsibilities. Implementing WebSockets for real-time communication enhances the chat experience, similar to WhatsApp. Let me know if you need help with code snippets for specific parts! 7.Testing: To test the "Create Chatroom" API endpoint in Postman for your Laravel application, follow these steps: 7.1. Start the Local Server If you haven't already, start your Laravel server by running: bash Copy code php artisan serve This will usually start the server at http://127.0.0.1:8000. 7.2. Open Postman and Set Up the Request
13. Open Postman and create a new POST request.
14. Set the Request URL to: arduino Copy code http://127.0.0.1:8000/api/chatrooms Make sure this URL matches your local server address, including the api prefix if you defined your routes in routes/api.php.
15. Set the Request Method to POST.
16. Add the Headers: o If your API requires authentication, add the necessary token in the Headers tab. For example:  Authorization: Bearer YOUR_TOKEN_HERE (replace YOUR_TOKEN_HERE with an actual token). o Set the Content-Type to application/json: plaintext Copy code Content-Type: application/json
17. Add the Body: o Go to the Body tab. o Select raw and set the format to JSON. o Add the following JSON data, replacing the values as needed: json Copy code { "name": "General Chat", "max_members": 10 }
18. Send the Request: o Click the Send button in Postman. o You should receive a response indicating whether the chatroom was created successfully. 7.3. Example Response If the request is successful, you should receive a 201 Created status with a response similar to this: json Copy code { "chatroom": { "id": 1, "name": "General Chat", "max_members": 10, "created_at": "2024-11-05T10:00:00.000000Z", "updated_at": "2024-11-05T10:00:00.000000Z" }, "message": "Chatroom created successfully." } If there’s an error (such as validation errors or missing fields), Laravel will return an appropriate response with a 400 or 422 status, and a message indicating what went wrong.
