+## Using EventSource
+
+Lynx provides the [EventSource](/api/lynx-api/global/fetch) with the same usage as the Web.
+
+You can refer to the MDN guides on [Using server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch) for more information.
+
+```typescript
+const url = 'https://sse.dev/test';
+const eventSource = new lynx.EventSource(url2);
+
+eventSource.onmessage = (event) => {
+  console.log('Received message:', event.data);
+};
+
+eventSource.onerror = (error) => {
+  console.error('EventSource failed:', error);
+};
+```

 ## Using Other Networking Libraries
 
 Since The Fetch API is built into Lynx. This means that you can use third party libraries that depend on it.

+## 使用 EventSource
+
+LynxSDK 提供 Web 标准完全一致的 `EventSource`，以处理 SSE 协议。
+
+你可以查阅 MDN 文档的 [Using server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events) 了解如何使用 `EventSource` 及 SEE 协议。
+
+```typescript
+const url = 'https://sse.dev/test';
+const eventSource = new lynx.EventSource(url2);
+
+eventSource.onmessage = (event) => {
+  console.log('Received message:', event.data);
+};
+
+eventSource.onerror = (error) => {
+  console.error('EventSource failed:', error);
+};
+```
+
 ## 使用其他网络库
 
 由于 Fetch API 已内置于 Lynx，这意味着您可以使用依赖于该 API 的第三方库。
