Overview
w_transport is a platform-independent HTTP and WebSocket client library for Dart, designed to work seamlessly across Android, iOS, Web, macOS, Windows, and Linux. It supports standard HTTP requests and WebSocket connections, with built-in compatibility for SockJS in environments where native WebSockets aren't available. The library includes mock utilities that simplify testing by allowing developers to simulate network behavior without actual network calls. Ideal for applications requiring reliable, cross-platform communication with backend services.
Use cases
- Sending HTTP requests from Flutter apps
- Establishing WebSocket connections in web and mobile apps
- Testing network logic with mock responses
- Building real-time features using WebSockets
- Creating portable networking layers across platforms
Key features
- Cross-platform HTTP and WebSocket support
- Built-in SockJS fallback for browsers
- Mock utilities for unit testing
- Consistent API across all platforms
- Lightweight and focused on transport layer
Suitable for
- Developers building multi-platform Flutter apps
- Teams needing consistent network behavior across devices
- Projects requiring testable network code
- Real-time data streaming applications
- Backend-agnostic communication layers
Considerations
- Requires understanding of HTTP and WebSocket protocols
- Limited to transport-level functionality (no serialization)
- Mock utilities are for testing only, not production use
- Not suitable for complex REST clients with caching or auth out of the box
- Depends on external packages for JSON parsing or request interception
