# Releases
## @langchain/langgraph-sdk@1.9.20

### Patch Changes

- [#2508](https://github.com/langchain-ai/langgraphjs/pull/2508)
[`41cd05a`](https://github.com/langchain-ai/langgraphjs/commit/41cd05a411ed262443c2bd1048e1b728b7331ac6)
Thanks [@christian-bromann](https://github.com/christian-bromann)! -
fix(sdk): hydrate custom HttpAgentServerAdapter via transport getState

StreamController now prefers adapter getState() before
client.threads.getState,
HttpAgentServerAdapter implements GET /threads/:id/state, and useStream
inherits
apiUrl from the transport so hydration no longer defaults to
localhost:8123.

## @langchain/angular@1.0.20

Assistant-UI Claude Example

This example combines:

@assistant-ui/react for the Claude-style chat surface
@langchain/react for streaming LangGraph state on the frontend
a basic langchain agent on the backend

What it shows

A Claude-inspired assistant-ui thread and composer
A local single-agent graph powered by langchain
How to bridge @langchain/react state into assistant-ui with useExternalStoreRuntime

Setup

Create a local .env file in this folder with:

OPENAI_API_KEY=your_openai_api_key
OPENAI_MODEL=gpt-4.1-mini

Optional overrides:

LANGGRAPH_API_URL=http://localhost:2024
VITE_LANGGRAPH_API_URL=http://localhost:2024
VITE_LANGGRAPH_ASSISTANT_ID=assistant-ui-claude

Run

pnpm --filter @examples/assistant-ui-claude dev

Then open the Vite URL shown in the terminal, usually http://localhost:5173.

The frontend talks directly to the LangGraph dev server at http://localhost:2024, which serves the local assistant-ui-claude graph from langgraph.json.
