The Nodes page (and any other recharts-using route) crashed in dev and prod with TypeError: require_isUnsafeProperty is not a function. Root cause: es-toolkit's package.json exports './compat/*' only via a default condition pointing at the CJS shims under compat/<name>.js. Those shims use a require_X.Y access pattern that Vite's optimizer (Rolldown in Vite 8) and the production Rolldown build both mishandle, losing the named-export accessor and calling the namespace object as a function. recharts imports a dozen of these subpaths with default- import syntax, so every chart path tripped the bug. The matching ESM build at dist/compat/<category>/<name>.mjs is fine, but it only carries a named export. Recharts uses default imports. Plug a small Rollup-compatible plugin (enforce: 'pre') in front of the resolver: any 'es-toolkit/compat/<name>' request becomes a virtual module that imports the named symbol from the right .mjs file and re-exports it as both default and named. The plugin is registered as a top-level plugin (for the prod build) and via the new Vite 8 optimizeDeps.rolldownOptions.plugins (for the dev pre-bundler), so both pipelines pick it up consistently.
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").
