Follow the [LangGraph Python quickstart](/langgraph-python/quickstart) to
|
|
configure the `sample_agent` graph. Start its existing LangGraph server:
|
|
|
|
```bash title="Agent application"
|
|
npx @langchain/langgraph-cli dev --port 8123 --no-browser
|
|
```
|
|
|
|
Point the native LangGraph adapter at that deployment:
|
|
|
|
```dotenv title=".env"
|
|
LANGGRAPH_DEPLOYMENT_URL=http://localhost:8123
|
|
```
|
|
|
|
The Runtime package installed by the Channels quickstart includes the native
|
|
LangGraph adapter.
|
|
|
|
LangGraph Server speaks the LangGraph API, so use `LangGraphAgent` rather
|
|
than `HttpAgent`. Return a fresh adapter for every channel thread:
|
|
|
|
```ts title="agent.ts"
|
|
import { LangGraphAgent } from "@copilotkit/runtime/langgraph";
|
|
|
|
export function makeAgent(threadId: string) {
|
|
const agent = new LangGraphAgent({
|
|
deploymentUrl: process.env.LANGGRAPH_DEPLOYMENT_URL!,
|
|
graphId: "sample_agent",
|
|
});
|
|
agent.threadId = threadId;
|
|
return agent;
|
|
}
|
|
```
