soroush.asadi 90ac0b81d1 feat: V2 microservices stack — backend services, gateway, JWT auth
Add full V2 architecture: identity, content, studio (.NET 10) and file,
render, notification, gateway (Go) services with vendored deps, plus DB
migrations, event/API contracts, and an init-db script.

Wire the Next.js frontend to the gateway: server-side JWT auth routes
(login/register/refresh/logout/me), gateway fetch helper, and session/
cookie/jwt helpers under src/lib.

Containerize the stack via docker-compose.v2.yml and per-service
Dockerfiles. Base images resolve through a Nexus mirror (Docker Hub) and
MCR directly; npm/NuGet pull from Nexus groups. Self-host fonts via
next/font/local to avoid Google Fonts (geo-blocked).

Add CI workflow and ignore .env.v2, *.stackdump, and .NET bin/obj.

Server-Sent Events

GoDoc Build Status codecov Go Report Card

Server-sent events (SSE) is a technology where a browser receives automatic updates from a server via HTTP connection. The Server-Sent Events EventSource API is standardized as part of HTML5[1] by the W3C.

Sample code

import "github.com/gin-contrib/sse"

func httpHandler(w http.ResponseWriter, req *http.Request) {
	// data can be a primitive like a string, an integer or a float
	sse.Encode(w, sse.Event{
		Event: "message",
		Data:  "some data\nmore data",
	})

	// also a complex type, like a map, a struct or a slice
	sse.Encode(w, sse.Event{
		Id:    "124",
		Event: "message",
		Data: map[string]interface{}{
			"user":    "manu",
			"date":    time.Now().Unix(),
			"content": "hi!",
		},
	})
}
event: message
data: some data\\nmore data

id: 124
event: message
data: {"content":"hi!","date":1431540810,"user":"manu"}
 

Content-Type

fmt.Println(sse.ContentType)
text/event-stream

Decoding support

There is a client-side implementation of SSE coming soon.
