Vchat-sdk is a SaaS (Software as a Service) chat system that offers real-time messaging capabilities for web and mobile applications. It consists of two parts: the server-side and the client-side. The server-side is built using Node.js and Socket.IO for real-time communication, while MongoDB is used for data storage.

A unique feature of vchat-sdk is its independence from Firebase for data storage. However, it does provide the option to enable push notifications using Firebase Cloud Messaging (FCM) or OneSignal.

About V_CHAT_SDK

• V_CHAT_SDK is a package written in pure Dart and NestJS for the server-side. It helps you add chat functionality to any existing or new Flutter mobile project, regardless of the back-end service you use.
• V_CHAT_SDK offers unlimited text, image, video, record, location, push notifications, and data control.
• With only 6 public APIs, V_CHAT_SDK is an easy way to integrate advanced real-time messaging into your chat.
• V_CHAT_SDK uses Node.js for its backend service and Firebase for push notifications. MongoDB is used as the message database, while the client-side is powered by Flutter.

About Microservices

1. Reduced load on your main server, as chat traffic can be high.
2. Improved scalability: Microservices make it easier to identify and resolve scaling bottlenecks at a per-microservice level.
3. Easy to build and maintain: Their single-purpose design enables smaller, cross-functional teams to specialize in a subset of the microservices within a solution.

Use Cases

1. Perfect for social media apps that require a chat system similar to WhatsApp or Facebook.
2. Ideal for e-commerce apps looking to add chat features, such as delivery or marketplace communication, like OLX or Facebook Marketplace.
3. Can be used for real-time user chat support.

How V_CHAT_SDK Works

V_CHAT_SDK connects with your backend service, regardless of the language or framework it uses. It communicates with your system through public APIs and runs separately, yet remains connected via these APIs.

When you register a new user in your system, call the V_CHAT_SDK public API to create a separate database for saving user information like names, images, and identifiers. Once the user is successfully connected in your client app ( typically after successful authentication), you need to connect the user to the V_CHAT_SDK system to enable communication with other users this done through using of flutter packages already build. If you have an existing production app and wish to integrate V_CHAT_SDK, you can migrate old users, as explained in the backend section.

Technologies

1. Nestjs is used for server-side code.
2. MongoDB stores chat texts and user data.
3. Socket.IO enables real-time communication.
4. FCM or OneSignal provide push notifications. You can choose between them or enable both, and V_CHAT_SDK will manage the user's platform availability.
5. Amazon AWS S3 securely stores user media with access restrictions using pre-signed URLs.
6. WebRTC is used for video and voice calls, but it's not 100% stable and requires a paid TURN server. Support for Agora.io will be added.
7. Client-side SDK supports Flutter for Android, iOS, web, Windows, and Mac.

Server Requirements for V_CHAT_SDK

V_CHAT_SDK is a lightweight SaaS chat system with minimal server resource requirements:

• 1 CPU core
• 1 GB RAM
• Fast SSD storage
• Ubuntu version 18 or higher
• Recommended hosting: DigitalOcean

Additionally, you need a MongoDB database for data storage. You can host a free MongoDB database on MongoDB Atlas, a cloud-based database service offering simple and secure data management.

With these minimum server requirements, you can easily set up V_CHAT_SDK and start enabling real-time messaging in your web or mobile applications.
