-# React + TypeScript + Vite
+# SenlinAI Web
 
-This template provides a minimal setup to get React working in Vite with HMR and some Oxlint rules.
+Svelte + TypeScript web client for the project workbench.
 
-Currently, two official plugins are available:
+## Scripts
 
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
+```powershell
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
+npm run dev
-
+npm test -- --run
-## React Compiler
+npm run build
-
+npx playwright test
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
-
-## Expanding the Oxlint configuration
-
-If you are developing a production application, we recommend enabling type-aware lint rules by installing `oxlint-tsgolint` and editing `.oxlintrc.json`:
-
-```json
-{
-  "$schema": "./node_modules/oxlint/configuration_schema.json",
-  "plugins": ["react", "typescript", "oxc"],
-  "options": {
-    "typeAware": true
-  },
-  "rules": {
-    "react/rules-of-hooks": "error",
-    "react/only-export-components": ["warn", { "allowConstantExport": true }]
-  }
-}
 ```
 
-See the [Oxlint rules documentation](https://oxc.rs/docs/guide/usage/linter/rules) for the full list of rules and categories.
+The login shell lets users enter the server IP address or domain name used as the API base URL.

 Do not hardcode this value into application source files. Pass it through `DATABASE_URL`.
 
+Run:
+
+```powershell
+Set-Location backend
+$env:DATABASE_URL='postgres://postgres:Weidong2023~!@8.137.107.29:19432/agent_dev?sslmode=disable'

+Expected: `TestPostgresPing` passes.
