• emitter-io

  0 2,886 1.6 Go

  High performance, distributed and low latency publish-subscribe platform.

  

• kubefwd

  2 2,447 5.8 Go

  Bulk port forwarding Kubernetes services for local development.

  

  Project mention: Using Telepresence 2 for Kubernetes debugging and local development | dev.to | 2021-04-15

  Kubefwd works similar to Telepresence by making your local environment think it is inside the cluster. The networking tunnel is one direction only. Telepresence is much smarter as it also makes the other cluster applications think that your local app is inside the same cluster. So with Kubefwd you only get 50% of what basic Telepresence offers. Telepresence also has volume mounting support for more advanced scenarios.

• gobgp

  Project mention: How I Stopped Coding Repetitive Service Components with Kong | dev.to | 2021-05-18

  Taking things to a broader level, Kuma is another platform agnostic-OSS solution for service mesh and microservice management – with control plane support of Kubernetes, virtual machines (VM), and even bare-metal environments. Kuma was donated to the Cloud Native Computing Foundation (CNCF) by Kong and still actively contributes to the evolving code base.

• nano

  1 1,709 1.0 Go

  Lightweight, facility, high performance golang based game server framework

  Project mention: New ‘Action Roguelike’ C++ Project on GitHub | news.ycombinator.com | 2021-01-16

  Couldn't you use just a vanilla Golang (or any other language) microservice for all of this? If you know what you are doing you can have a bulletproof basic service with all of the above up and running in no time, just add your game logic. Most of your requirements are part and parcel of any modern commercial Docker microservice. Never mind that such frameworks already exist, e.g. nano [0] specifically designed for games.

  Scalability is also not an issue. Number of simultaneous players and objects is limited by bandwidth and latency only. There are certainly no barriers to handling multi-million entity databases on any modern server. You're really only limited by how much data you can push out to your users within an update tick. And of course by how much money you're willing to pay for back end compute capacity on an ongoing basis. But those costs are very low these days, especially if you have dedicated servers rather then AWS/Google/Azure.

  I think perhaps the issue is not so much that frameworks don't exist, but rather that no single framework has achieved popularity in the game design community. The indie crowd is not likely to want to, or afford to, run servers for years and years, so the demand is not there. The triple-A studios roll their own.

• mqttPaho

  1 1,629 5.9 Go

  

  Project mention: Are websockets right for this? | reddit.com/r/golang | 2021-04-27

  I suggest PubSub with queue persistence, so https://github.com/eclipse/paho.mqtt.golang with https://mosquitto.org/ as broker. Mosquitto also supports websockets interface and can be run over TLS.
