I'm really excited about this. It's by the creator of uWebSockets[0], alexhultman[1]. It looks like it builds heavily on his work there. Based on the performance compared to redis, this is already an impressive start. Excited to see where this goes! I also second an attempt at comparing it to ZeroMQ, even though they're obviously somewhat different. [0] https://github.com/uNetworking/uWebSockets [1] https://github.com/alexhultman

For anyone else slightly confused at first: the Discord Linux release (https://discordapp.com/download) includes uWebSockets in ./resources/bootstrap/discord_rpc/uws.js. This is only the JS source code and there is no licensing information attached whatsoever. This directly conflicts with uWebSocket's licence (https://github.com/uWebSockets/uWebSockets/blob/master/LICEN...), which clearly states: "3. This notice may not be removed or altered from any source distribution."

This is cool, but I'm a bit confused. Websockets have been around for a long time now, and there are tons of popular libraries (like socket.io, but more importantly, you should check out the high performance https://github.com/uWebSockets/uWebSockets instead). Is all this doing trying to encourage awareness that using websockets is good? If so, awesome. Else, what is it? Because it does not discuss how Websockets lose state on reload. Your game will be in a completely wrong state. Managing and maintaining state is the important thing (which is what https://github.com/amark/gun does, which is of course also "websockets-first"). When you reload your game, it should return/remain as it was, or else half your players are going to see a half-broken system!
