How does Nano compare to Colyseus for real-time game servers?

Nano is a Go-based framework focusing on server-side networking with built-in distributed support, while Colyseus is a Node.js solution with more integrated room management. Nano offers better performance for Go ecosystems but requires more setup for client integration and has a steeper learning curve for non-Go developers.

How to scale Nano servers horizontally for large player counts?

Use Nano's built-in distributed system solutions, such as running multiple instances and employing components like agents for message dispatch. Refer to the cluster demo example for implementation details on load balancing and inter-server communication.

What client platforms does Nano support out of the box?

Nano provides client libraries for JavaScript, TypeScript, and game engines like Egret and Cocos Creator, enabling cross-platform development for web and mobile games, as documented in the Resources section of the README.

Is Nano suitable for building non-game real-time applications like chat apps?

Yes, Nano can handle chat applications due to its WebSocket support and real-time capabilities; a chat room demo is provided in the examples with minimal code. However, it lacks pre-built features like user authentication or message persistence, requiring custom implementation.

How to handle database operations asynchronously in Nano without blocking?

Run database queries or other slow tasks in goroutines and use nano.Invoke to process results in the main logic thread, as shown in the async task example in the README. This prevents blocking and maintains server responsiveness.

What are the performance benchmarks for Nano under high load?

The README includes benchmarks like the PingPong test, showing high IOPS on standard hardware (e.g., 110,000 average on an i5-6500), but real-world performance depends on deployment, network conditions, and custom game logic optimization.

nano — Lightweight Go Game Server Framework

What is nano?

Nano is a lightweight, high-performance game server framework built in Go, designed to simplify the development of real-time multiplayer applications. It provides a core network architecture and a suite of tools that help developers eliminate repetitive networking code, allowing them to focus on game logic and business rules. The framework supports distributed systems, making it suitable for scalable game server deployments.

Target Audience

Backend developers and engineers building real-time game servers, social games, mobile games, or any distributed multiplayer application in Go. It is particularly useful for teams needing a performant and scalable networking foundation without reinventing the wheel.

Value Proposition

Developers choose Nano for its simplicity, performance, and built-in support for distributed systems, which reduces development time for common networking tasks. Its component-based architecture and cross-platform client libraries provide flexibility and ease of integration compared to building custom solutions from scratch.

Lightweight, facility, high performance golang based game server framework

Use Cases

Best For

Building real-time multiplayer game servers in Go
Creating scalable distributed systems for online games
Developing social or mobile games with WebSocket communication
Prototyping game servers quickly with a lightweight framework
Integrating Lua scripting into game server components
Implementing chat rooms or real-time collaboration features

Not Ideal For

Projects not using Go or requiring polyglot microservices across different server languages
Simple applications where lightweight HTTP/REST APIs suffice without real-time networking needs
Teams seeking pre-built game mechanics, physics engines, or extensive out-of-the-box game logic libraries
Environments with strict dependency minimization policies due to Nano's reliance on Protocol Buffers, gRPC, and other external tools

Pros & Cons

Pros

Component-Based Architecture

Allows building applications as collections of components with handlers, simplifying code organization and reuse, as illustrated in the 'How to build a system with Nano' section and accompanying diagram.

Built-In Distributed Support

Provides ready-made solutions for creating distributed game servers, enabling scalable multi-server deployments without custom clustering code, demonstrated in the cluster chat demo.

Efficient Async Handling

Supports running slow tasks like database queries in goroutines and handling results in the main logic thread using nano.Invoke, with a clear code example in the asynchronous task section.

Cross-Platform Client Libraries

Offers client libraries for JavaScript, TypeScript, and game engines like Egret and Cocos Creator, facilitating integration with various frontends, as listed in the Resources section.

Cons

Incomplete Documentation

The README explicitly notes that Lua integration documentation is incomplete, which may hinder developers needing scripting support for game logic.

Complex Dependency Setup

Requires manual installation of multiple dependencies like Protocol Buffers, gRPC, and specific tools, adding to initial setup time and potential maintenance overhead.

Niche Game Server Focus

Designed primarily for game servers, making it less versatile for general-purpose real-time applications outside gaming, with limited examples for other use cases.
