* perf(frontend): lazy-load modals on inbounds / clients / index pages Modals on the three list pages were imported statically, so the JS + CSS for every form, info, qr, log, backup, metrics, system-history, version, and config-text modal sat in the initial bundle even though they're only needed after a click. Converted those imports to React.lazy() and gated each modal with a new LazyMount helper that mounts on first open and keeps the component mounted thereafter so AntD close animations still play. Build now emits a dedicated chunk per modal — InboundFormModal at 66 kB (13 kB gzipped) and InboundInfoModal at 23 kB (4 kB gzipped) are the largest, totalling roughly 150 kB of code that no longer parses on first paint. Profiler measured the inbounds-page React render tree drop from ~444 ms to ~254 ms on a prod build. * perf(frontend): split codemirror / jalali / otpauth into lazy vendor chunks Heavy libs (codemirror, persian-calendar-suite, otpauth) and antd's rc-/cssinjs transitive deps used to fall into the catch-all `vendor` chunk and load with every entry point. Give them their own manualChunks groups so they only load with the lazy modal/page that needs them. Initial vendor (catch-all) drops from 1293 kB / 408 kB gzip to 76 kB / 27 kB gzip; codemirror (408 kB / 131 kB gzip) is now on the JsonEditor lazy path instead of the inbounds/clients/index initial load.
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").
