* fix(frontend): reload page on Vite chunk preload error after upgrade
After a panel upgrade the embedded dist/ ships with new hashed chunk
filenames, so SPA tabs loaded before the upgrade hold references to
chunks that no longer exist on the server and lazy modals 404. Hook
`vite:preloadError` and force one full reload (guarded by a session
flag) so the browser picks up the new index.html.
* Revert "fix(frontend): reload page on Vite chunk preload error after upgrade"
This reverts commit bf0754d21e.
* fix(frontend): resolve lazy chunk URLs against runtime base path
Vite's default chunk-preload helper prepends a hardcoded `/` to asset
filenames, so dynamic chunk preloads always 404 when the panel is
served under a non-root webBasePath (e.g. /CxuVUNgm5mRLmjPhp3/). Use
experimental.renderBuiltUrl to embed window.X_UI_BASE_PATH (injected
by dist.go) as the runtime prefix, so __vite__mapDeps emits URLs like
`<basePath>assets/<file>` regardless of where the dist is mounted.
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").
