Rewrite FinalMaskForm.tsx from a class-coupled component (mutated stream.finalmask.tcp[] via .addTcpMask/.delTcpMask methods, notified parent via onChange callback) into a Pattern A sub-form: takes a NamePath base, a FormInstance, and the surrounding network/protocol, then composes Form.List + Form.Item at absolute paths under that base. All array structures use nested Form.List — tcp/udp mask arrays, the clients/servers groups in header-custom (Form.List of Form.List of ItemEditor), and the noise list. Type Selects use onChange to reset the settings sub-object via form.setFieldValue, mirroring the legacy changeMaskType behavior. The kcp.mtu side effect on xdns type change is preserved. Wired into both InboundFormModal and OutboundFormModal stream tabs, placed after the sockopt section. The component is the first Pattern A consumer of nested Form.List inside another Form.List, so it stands as the reference for future nested-array sub-forms.
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").
