A lightweight Go library for network I/O event notification using epoll/kqueue, designed for building high-performance network applications.
Event is a network I/O event notification library written in Go that enables developers to build high-performance network applications. It uses system-level polling mechanisms like epoll and kqueue to efficiently monitor file descriptors for read, write, and timeout events, minimizing resource usage while maximizing throughput.
Go developers building network servers, proxies, or any application requiring efficient handling of multiple concurrent I/O operations, especially those targeting Linux, FreeBSD, or Darwin platforms.
Developers choose Event for its simplicity, low memory footprint, and direct integration with Go, offering a native alternative to C libraries like libevent without sacrificing performance or control.

Uses epoll and kqueue for fast I/O event notification, similar to libevent, ensuring high performance for network applications as stated in the README and description.
Optimized for low memory usage, making it suitable for resource-constrained environments, a key feature highlighted in the README.
Offers an intuitive interface for event creation, attachment, and dispatch, with clear examples like EvRead|EvTimeout combinations in the README.
Supports event priorities (e.g., HP for high priority), allowing critical events to be handled first when multiple trigger simultaneously, as shown in the code examples.
Only supports UNIX-like systems (Linux, BSD, Darwin) as per the badges, excluding Windows, which restricts cross-platform deployment.
Requires manual handling of file descriptors and syscalls, making it error-prone and less accessible compared to higher-level Go concurrency patterns.
Being a niche library, it lacks extensive documentation, community support, and pre-built integrations, unlike more popular frameworks.
