grpcSimple

Documentation

Overview

Package grpcHardcore implements grpc tunnel without importing google.golang.org/grpc.

Reference

https://github.com/Dreamacro/clash/blob/master/transport/gun/gun.go, which is under MIT license

在 clash的客户端实现 的 基础上 继续用 golang的 http2包 实现了 grpc 的 基本服务端，并改进了 原代码。

grpcSimple包 比grpc包 小很多，替代grpc包的话，可以减小 4MB 左右的可执行文件大小。但是目前不支持 multiMode。

grpcSimple包 是很棒 很有用的 实现，未来可以添加 针对 grpc的ServiceName的回落。
