undici 8.5.0 requires Node >= 22.19.0 (its declared engines), so CI's Node 20.x could not load undici's CacheStorage (missing webidl.util.markAsUncloneable) and the proxy integration tests failed. Bump the CI setup-node to 22.x to match the repo's Node floor. Reconcile the declared floor with undici's real requirement: bump root engines.node to >=22.19.0 and correct the CLI README note (undici 8.5.0 needs >=22.19.0, not >=22.7.5). Also document proxy support in the web README and clarify that a caller-supplied eventSourceInit.fetch bypasses the proxy wrapper by design.

# React + TypeScript + Vite
|
|
|
|
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
|
|
|
|
Currently, two official plugins are available:
|
|
|
|
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
|
|
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
|
|
|
|
## React Compiler
|
|
|
|
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 ESLint configuration
|
|
|
|
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
|
|
|
|
```js
|
|
export default defineConfig([
|
|
globalIgnores(['dist']),
|
|
{
|
|
files: ['**/*.{ts,tsx}'],
|
|
extends: [
|
|
// Other configs...
|
|
|
|
// Remove tseslint.configs.recommended and replace with this
|
|
tseslint.configs.recommendedTypeChecked,
|
|
// Alternatively, use this for stricter rules
|
|
tseslint.configs.strictTypeChecked,
|
|
// Optionally, add this for stylistic rules
|
|
tseslint.configs.stylisticTypeChecked,
|
|
|
|
// Other configs...
|
|
],
|
|
languageOptions: {
|
|
parserOptions: {
|
|
project: ['./tsconfig.node.json', './tsconfig.app.json'],
|
|
tsconfigRootDir: import.meta.dirname,
|
|
},
|
|
// other options...
|
|
},
|
|
},
|
|
])
|
|
```
|
|
|
|
You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
|
|
|
|
```js
|
|
// eslint.config.js
|
|
import reactX from 'eslint-plugin-react-x'
|
|
import reactDom from 'eslint-plugin-react-dom'
|
|
|
|
export default defineConfig([
|
|
globalIgnores(['dist']),
|
|
{
|
|
files: ['**/*.{ts,tsx}'],
|
|
extends: [
|
|
// Other configs...
|
|
// Enable lint rules for React
|
|
reactX.configs['recommended-typescript'],
|
|
// Enable lint rules for React DOM
|
|
reactDom.configs.recommended,
|
|
],
|
|
languageOptions: {
|
|
parserOptions: {
|
|
project: ['./tsconfig.node.json', './tsconfig.app.json'],
|
|
tsconfigRootDir: import.meta.dirname,
|
|
},
|
|
// other options...
|
|
},
|
|
},
|
|
])
|
|
```
|
|
|
|
## HTTP proxy support
|
|
|
|
The web backend connects to remote MCP servers through the shared Node transport (`core/mcp/node/transport.ts`), which honors the conventional proxy environment variables: `HTTPS_PROXY` / `HTTP_PROXY` (and their lowercase forms) select the proxy, and `NO_PROXY` exempts hosts. Routing is powered by [`undici`](https://www.npmjs.com/package/undici)'s `EnvHttpProxyAgent`, imported lazily only when a proxy variable is set, so runs without a proxy configured pay no cost. See the CLI README for more detail.
