+# Explorer Frontend Testing
+
+## Summary
+
+Path-based URLs (e.g. `/address/0x99b3511a2d315a497c8112c1fdd8d508d4b1e506`) now work on the explorer. The fix includes:
+
+1. **SPA path-based routing** – `applyHashRoute()` in `frontend/public/index.html` reads both `pathname` and `hash`, so `/address/0x...`, `/tx/0x...`, `/block/123`, etc. load correctly.
+2. **Nginx SPA paths** – Nginx serves `index.html` for `/address`, `/tx`, `/block`, `/token`, `/blocks`, `/transactions`, `/bridge`, `/weth`, `/watchlist`, and `/nft`.
+3. **HTTP + HTTPS** – Both HTTP (for internal tests) and HTTPS serve the SPA for these paths.
+
+## Test Commands
+
+### Shell E2E (curl-based)
+
+```bash
+./explorer-monorepo/scripts/e2e-test-explorer.sh
+```
+
+Requires network access to `192.168.11.140` (VMID 5000).
+
+### Playwright E2E
+
+```bash
+cd explorer-monorepo
+EXPLORER_URL="http://192.168.11.140" npx playwright test e2e-explorer-frontend.spec.ts --project=chromium
+```

+| Tx | `/tx/<hash>` |

+
+## Proxy 301 Note
+
+If `https://explorer.d-bis.org/address/0x...` returns 301, the proxy (NPMplus/Cloudflare) may need configuration. The VM nginx serves the SPA correctly. Workaround: use `#/address/0x...` or access via LAN.
