Schema fixes per https://xtls.github.io/config/transports/finalmask.html and https://xtls.github.io/config/transports/sockopt.html: finalmask: - QuicCongestionSchema: remove non-doc 'cubic', keep reno/bbr/brutal/force-brutal - Add BbrProfileSchema (conservative/standard/aggressive) and bbrProfile field - brutalUp/brutalDown: number -> string per docs (units like '60 mbps') - Tighten ranges: maxIdleTimeout 4-120, keepAlivePeriod 2-60, maxIncomingStreams min 8 - UdpMaskTypeSchema: add missing 'sudoku' - udpHop.interval stays as preprocessed string-range per intentional B19 divergence sockopt: - tcpFastOpen: boolean -> union(boolean, number) per docs (number tunes queue size) - mark: drop min(0) (can be any int) - domainStrategy default: 'UseIP' -> 'AsIs' per docs - tcpKeepAlive Interval/Idle defaults: 0/300 -> 45/45 per docs (outbound) - Add AddressPortStrategySchema enum (7 values) + addressPortStrategy field - Add HappyEyeballsSchema (tryDelayMs/prioritizeIPv6/interleave/maxConcurrentTry) - Add CustomSockoptSchema (system/type/level/opt/value) + customSockopt array Bug fixes: - options.ts: Address_Port_Strategy values were lowercase ('srvportonly'); xray-core requires camelCase ('SrvPortOnly'). Fixed all 6 entries. - OutboundFormModal: domainStrategy Select was mistakenly populated from ADDRESS_PORT_STRATEGY_OPTIONS; now uses DOMAIN_STRATEGY_OPTION. - OutboundFormModal: inline sockopt defaults (hardcoded {acceptProxyProtocol: false, domainStrategy: 'UseIP', ...}) replaced with SockoptStreamSettingsSchema.parse({}) so schema is the single source. Form additions (both InboundFormModal + OutboundFormModal): - Address+port strategy Select - Happy Eyeballs Switch + sub-form (tryDelayMs/prioritizeIPv6/interleave/maxConcurrentTry) - Custom sockopt Form.List (system/type/level/opt/value) - FinalMaskForm: BBR Profile Select (visible when congestion='bbr'), Brutal Up/Down placeholders updated to string format Golden fixtures (8 new + 4 xhttp extras): - finalmask/{tcp-mask, udp-mask, quic-params, combined}.json — cover all TCP mask types, 7 UDP mask types including new sudoku, full QUIC params shape - sockopt/{defaults, tcp-tuning, tproxy, full}.json — full sockopt knobs - stream/xhttp-{basic, extra-padding, extra-placement, extra-tuning}.json — cover the extra-blob fields bundled into share-link extra=<json> Tests now at 312 (up from 300); typecheck/lint clean.
3x-ui frontend
React 19 + Ant Design 6 + TypeScript + Vite 8. Multi-page app — one HTML
entry per panel route — built into ../web/dist/ and embedded into the
Go binary via embed.FS.
Dev
npm install
npm run dev
Vite serves on http://localhost:5173/. API calls and /panel/* routes
proxy to the Go panel at http://localhost:2053/, so start the Go panel
first (go run main.go) and then Vite.
The proxy auto-rewrites /panel, /panel/settings, /panel/inbounds,
/panel/xray to the matching Vite-served HTML in dev mode (see
MIGRATED_ROUTES in vite.config.js), so the sidebar's
production-style links work without round-tripping through Go.
Production build
npm run build
Outputs to ../web/dist/ (HTML at the root, hashed JS/CSS under
assets/). The Go binary embeds this directory at compile time and
web/controller/dist.go serves the per-page HTML.
Type check and lint
npm run typecheck
npm run lint
tsc --noEmit against tsconfig.json (strict mode, jsx: "react-jsx",
@/* → src/* alias). ESLint 10 with eslint.config.js (flat config)
— @eslint/js recommended plus typescript-eslint and
eslint-plugin-react-hooks rules.

Adding a new page
- Add
frontend/<page>.htmlreferencing/src/entries/<page>.tsx. - Add
src/entries/<page>.tsxthat imports the page component and mounts it withcreateRoot(...).render(...). - Add the page component under
src/pages/<page>/. - Register the entry in
rollupOptions.inputinvite.config.js. - If the page is reachable from the sidebar at
/panel/<route>, add it toMIGRATED_ROUTESso the dev proxy serves the Vite HTML. - Wire the Go controller to
serveDistPage(c, "<page>.html").
