Maksim Alekseev 1f90d2a6ee feat(inbound): Advanced XHTTP and external TLS proxy settings (#4491)
*  Introduce extended XHTTP and external proxy settings

*  Add custom SNI for proxy

*  Add previous changes into React version of app

* fix(sub): isolate per-proxy tlsSettings during external-proxy iteration

cloneMap (Clash) is shallow and `newStream := stream` (JSON) is an alias,
so tlsSettings was shared across iterations. The new applyExternalProxyTLSToStream
mutates it, leaking one proxy's serverName/fingerprint/alpn into the next
(only overwritten when the next proxy explicitly sets the same field).

Add cloneStreamForExternalProxy: shallow clones the top-level stream plus
deep clones tlsSettings and tlsSettings.settings. Regression test locks
in that proxy B does not inherit proxy A's fingerprint/alpn when B leaves
them unset.

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

  1. Add frontend/<page>.html referencing /src/entries/<page>.tsx.
  2. Add src/entries/<page>.tsx that imports the page component and mounts it with createRoot(...).render(...).
  3. Add the page component under src/pages/<page>/.
  4. Register the entry in rollupOptions.input in vite.config.js.
  5. If the page is reachable from the sidebar at /panel/<route>, add it to MIGRATED_ROUTES so the dev proxy serves the Vite HTML.
  6. Wire the Go controller to serveDistPage(c, "<page>.html").
