A robust, clean, and efficient real-time bidirectional socket library for Go backends and JavaScript clients.
Glue is a real-time bidirectional socket library that connects web browsers with Go backends, providing a robust alternative to Socket.io. It automatically selects the best socket layer (WebSockets or AjaxSockets) and handles reconnections and caching to ensure reliable communication. The library is designed for simplicity and efficiency in building real-time applications.
Developers building real-time web applications who need a reliable socket library for Go backends and JavaScript clients, especially those seeking a cleaner and more stable alternative to Socket.io.
Glue offers a fixed API with no breaking changes, thread-safe server implementation, and automatic fallback handling, making it a robust and efficient choice for real-time communication without the complexity of other libraries.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Automatically detects and switches between WebSockets and AjaxSockets based on browser support, ensuring connectivity in restrictive environments without manual intervention.
Configurable reconnection delays, attempts, and caching bridge disconnections, maintaining data integrity and reducing downtime in unreliable networks.
The Go server implementation is explicitly designed as thread-safe, enabling reliable concurrent operations for high-traffic real-time applications.
Supports separate channels within a single socket connection, allowing organized data flow and reducing complexity for multi-faceted applications.
The API is fixed with no breaking changes, providing long-term stability and reducing maintenance overhead for production deployments.
Requires explicit discarding of unread data with DiscardRead() to prevent socket blockage and closure, adding developer overhead and risk of errors if overlooked.
Only supports WebSockets and AjaxSockets, lacking modern alternatives like WebTransport, which may limit performance or compatibility in cutting-edge environments.
Documentation is basic with GoDoc and simple examples, offering little guidance for complex scenarios such as scaling or integration with other Go frameworks.
Broadcasting and other advanced functionalities require manual implementation using server methods like Sockets or OnNewSocket, unlike libraries with out-of-the-box solutions.
