* feat(sub): add Happ client integration, routing presets, and app management Implement comprehensive Happ proxy client integration according to official developer specifications. - Fix header emission on disabled routing and hidden settings to send explicit '0' headers rather than omitting, allowing Happ clients to reset cached settings. - Add support for 'happ://routing/off' deeplink in routing validation. - Preserve '?serverDescription=' query parameters in link fragments without escaping to support Happ server subtitles across VMess, VLESS, Trojan and SS. - Add Happ application management headers: ProviderID, New-Url, Fallback-Url, Sub-Info banners, Sub-Expire notifications, No-Limit mode, hardware ID enforcement, TUN modes/types, route exclusions, APNS exclusions, and per-app proxy settings. - Add curated routing presets (Iran Bypass, China Direct, AdBlock, Global) and interactive visual rule generator in frontend settings. - Synchronize all 13 translation locales with native Persian, Russian, and Chinese translations. * fix(sub): keep Happ header overrides behind the auto-detect opt-in The Routing-Enable/Hide-Settings off values were emitted on the User-Agent alone, so every panel that upgraded would push "Routing-Enable: 0" — documented by happ.su as disabling routing globally — to every Happ client without the operator enabling anything. They now ride subHappAutoDetect like every other Happ header. Two further mismatches against the vendor spec: - serverDescription was written as a key of the VMess base64 JSON object. happ.su documents it as a "#Title?serverDescription=<base64>" link parameter or a JSON "meta" entry, so the caption never reached Happ while every other VMess consumer received an unknown key. Dropped rather than moved: emitting the documented form is unsafe here because our own parser base64-decodes the whole VMess body (internal/util/link/outbound.go). - The TUN Mode dropdown stored the literal "default", forwarded as "Tun-Mode: default", where happ.su documents system|gvisor only. It now stores the unset value so no header is sent. TUN Type "default" is a documented value and is unchanged. Each fix carries a test that fails without it.
3x-ui Documentation
The official documentation and product site for 3x-ui — an advanced web panel for managing Xray-core servers.
Overview
This directory (docs/ in the 3x-ui monorepo) contains
the source for docs.sanaei.dev — a static-first documentation and
marketing site built with Fumadocs on Next.js. It has no backend,
no database, and no auth: every page is prerendered and every tool runs entirely in the
browser.
What's inside
The documentation walks you through 3x-ui from first install to day-to-day operation:
- Getting Started — installation, first login, and updating or uninstalling the panel.
- Configuration — the panel, inbounds, REALITY, transports, clients, subscriptions, and share links.
- Operations — reverse proxy, multi-node setups, outbounds & routing, backup/restore, the Telegram bot, and security.
- Reference — environment variables, the database, ports & firewall, and the HTTP API.
- Help — troubleshooting, FAQ, migration, and how to contribute.
Interactive tools
The site ships with in-browser helpers that generate configuration for you — no data ever leaves your browser:
| Tool | What it does |
|---|---|
| REALITY Config Generator | Build a valid REALITY inbound configuration. |
| Share Link Inspector | Decode and inspect vless:// / vmess:// share links. |
| Install Command Builder | Assemble the right install command for your setup. |
| Reverse Proxy Generator | Generate reverse-proxy configs (Nginx / Caddy). |
| Protocol Wizard | Pick and configure the right protocol for your needs. |
| Firewall Rules Generator | Produce firewall rules for your ports. |

Quick start
This project uses pnpm (npm lockfiles are gitignored). Run everything
from the docs/ directory:
cd docs
pnpm install
pnpm dev # http://localhost:3000
Useful scripts:
| Script | Description |
|---|---|
pnpm dev |
Start the dev server |
pnpm build |
Production build (also typechecks) |
pnpm typecheck |
Generate MDX/route types and tsc --noEmit |
pnpm lint |
Run oxlint (.oxlintrc.json) |
pnpm test |
Run unit tests (Vitest) |

Project structure
app/ # Next.js App Router — layouts, home, docs, OG images, search, llms.txt
components/ # React components — interactive tools, home sections, MDX bindings
content/docs/ # MDX documentation, one folder per locale (en · fa · ru · zh)
lib/ # source config, i18n, GitHub stats, and the unit-tested lib/xray logic
public/ # static assets — logos, favicon, openapi.json, CNAME
scripts/ # build-time scripts (API reference generation)
source.config.ts # Fumadocs MDX schema & collection config
next.config.mjs # Next.js config (static-export gating)
proxy.ts # i18n middleware
Internationalization
Documentation is authored in English. Persian (fa, RTL), Russian (ru), and
Chinese (zh) locales are wired up; untranslated pages fall back to English so they
never 404. English URLs are unprefixed; other locales live under /fa, /ru, /zh.
Deployment
The site builds for two targets:
- Vercel / Node —
pnpm build(static search index + prerendered OG images). - GitHub Pages (static export) —
DEPLOY_TARGET=static pnpm build→out/.
