How do I set up WebSocket Manager in an ASP.NET Core project?

Start by adding the NuGet package, then configure the middleware in Startup.cs and define handler classes for method invocation. Refer to the samples folder in the repository for basic implementation examples, as mentioned in the README.

WebSocket Manager vs SignalR: which is better for new projects?

SignalR is now the official choice with more features, fallback transports, and better support. WebSocket Manager is only preferable if you need a minimal, WebSocket-only solution and are comfortable with its limitations and unofficial status.

Does WebSocket Manager handle automatic reconnections?

No, it lacks built-in reconnection logic, unlike SignalR which manages this automatically. You'll need to implement custom reconnection handling in your client code, adding complexity.

Is WebSocket Manager compatible with .NET 5 or later versions?

It targets .NET Core, so it might work with newer versions, but since it's not actively maintained, compatibility isn't guaranteed. Check the GitHub repository for recent updates or forks.

Can I use WebSocket Manager for server-to-server communication?

Yes, the .NET Core client allows server-to-server or desktop application communication over WebSockets, as stated in the README's features, but scalability might be limited compared to dedicated messaging systems.

What happens if WebSockets are blocked in a client environment?

The connection will fail entirely because WebSocket Manager doesn't support fallback transports. You'd need to implement alternative methods or switch to a library like SignalR that handles this automatically.

What is websocket-manager?

WebSocket Manager is an ASP.NET Core middleware that provides real-time communication capabilities to .NET Core applications. It enables bidirectional method invocation between client and server over WebSocket connections, serving as a lightweight alternative to SignalR while it was unavailable for ASP.NET Core.

Target Audience

ASP.NET Core developers needing real-time functionality in their applications, particularly those who couldn't wait for the official SignalR release for .NET Core.

Value Proposition

Developers choose WebSocket Manager for its immediate availability as a SignalR-inspired solution, its simplicity compared to full SignalR, and its support for both TypeScript/JavaScript and .NET Core clients.

Overview

Real-Time library for ASP .NET Core

Use Cases

Best For

Adding real-time features to ASP.NET Core applications
Building chat applications with .NET Core backends
Creating dashboard applications with live data updates
Implementing bidirectional communication in .NET Core projects
Developing applications needing server-to-client method invocation
Projects requiring a lightweight alternative to SignalR for ASP.NET Core

Not Ideal For

Projects requiring transport fallbacks like Server-Sent Events or Long Polling for broader client compatibility
Enterprises needing official Microsoft support, long-term maintenance, and integration with Azure services
Applications that depend on SignalR's mature ecosystem, extensive documentation, and community plugins
Teams building scalable real-time systems with built-in features like connection management across servers

Pros & Cons

Pros

Lightweight Immediate Solution

Created as a stopgap when SignalR for ASP.NET Core was delayed, it provides essential real-time functionality without the overhead of a full framework, as noted in the README's philosophy.

Bidirectional Method Invocation

Enables both client and server to invoke each other's methods over WebSockets, mirroring SignalR's core API for simplified real-time communication.

Cross-Platform Client Support

Includes a TypeScript/JavaScript client for web apps and a .NET Core client for server-to-server or desktop use, offering flexibility across different application types.

SignalR-Inspired Familiarity

Uses an API similar to SignalR, making it easy for developers with SignalR experience to adopt, as highlighted in the README's feature list.

Cons

Limited Transport Options

Relies solely on WebSockets without fallback mechanisms, which can break in environments with restrictive firewalls or older clients that SignalR handles gracefully.

Unofficial and Potentially Stale

As a third-party library created to fill a temporary gap, it risks abandonment now that official SignalR is available, leading to security and compatibility concerns over time.

Sparse Documentation and Examples

The README primarily directs users to sample code in the repository, lacking comprehensive guides, which can increase setup time and troubleshooting effort.

Open Source Alternative To

websocket-manager is an open-source alternative to the following products:

SignalR

SignalR is a .NET library for adding real-time web functionality to applications, enabling server-side code to push content to clients instantly.
