📄 Description

This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

Minor Changes

  • #1852 2ea3128 Thanks @hntrl! - feat: add type utilities for authoring graph nodes and conditional edges

    New exported type utilities for improved TypeScript ergonomics:

    • ExtractStateType<Schema> - Extract the State type from any supported schema (StateSchema, AnnotationRoot, or Zod object)
    • ExtractUpdateType<Schema> - Extract the Update type (partial state for node returns) from any supported schema
    • GraphNode<Schema, Context?, Nodes?> - Strongly-typed utility for defining graph node functions with full inference for state, runtime context, and optional type-safe routing via Command
    • ConditionalEdgeRouter<Schema, Context?, Nodes?> - Type for conditional edge routing functions passed to addConditionalEdges

    These utilities enable defining nodes outside the StateGraph builder while maintaining full type safety:

    import {
  StateSchema,
  GraphNode,
  ConditionalEdgeRouter,
  END,
} from "@langchain/langgraph";
import { z } from "zod/v4";

const AgentState = new StateSchema({
  messages: MessagesValue,
  step: z.number().default(0),
});

interface MyContext {
  userId: string;
}

// Fully typed node function
const processNode: GraphNode<typeof AgentState> = (state, runtime) => {
  return { step: state.step + 1 };
};

// Type-safe routing with Command
const routerNode: GraphNode<
  typeof AgentState,
  MyContext,
  "agent" | "tool"
> = (state) => new Command({ goto: state.needsTool ? "tool" : "agent" });

// Conditional edge router
const router: ConditionalEdgeRouter<
  typeof AgentState,
  MyContext,
  "continue"
> = (state) => (state.done ? END : "continue");

  • #1842 7ddf854 Thanks @hntrl! - feat: StateSchema, ReducedValue, and UntrackedValue

    StateSchema provides a new API for defining graph state that works with any Standard Schema-compliant validation library (Zod, Valibot, ArkType, and others).

    Standard Schema support

    LangGraph now supports Standard Schema, an open specification implemented by Zod 4, Valibot, ArkType, and other schema libraries. This means you can use your preferred validation library without lock-in:

    import { z } from "zod"; // or valibot, arktype, etc.
import {
  StateSchema,
  ReducedValue,
  MessagesValue,
} from "@langchain/langgraph";

const AgentState = new StateSchema({
  messages: MessagesValue,
  currentStep: z.string(),
  count: z.number().default(0),
  history: new ReducedValue(
    z.array(z.string()).default(() => []),
    {
      inputSchema: z.string(),
      reducer: (current, next) => [...current, next],
    }
  ),
});

// Type-safe state and update types
type State = typeof AgentState.State;
type Update = typeof AgentState.Update;

const graph = new StateGraph(AgentState)
  .addNode("agent", (state) => ({ count: state.count + 1 }))
  .addEdge(START, "agent")
  .addEdge("agent", END)
  .compile();

    New exports

    • StateSchema - Define state with any Standard Schema-compliant library
    • ReducedValue - Define fields with custom reducer functions for accumulating state
    • UntrackedValue - Define transient fields that are not persisted to checkpoints
    • MessagesValue - Pre-built message list channel with add/remove semantics

Patch Changes

  • #1901 6d8f3ed Thanks @dqbd! - Perform reference equality check on reducers before throwing "Channel already exists with a different type" error

  • Updated dependencies [5629d46, 78743d6]:

    • @langchain/langgraph-sdk@1.5.4

@langchain/langgraph-sdk@1.5.4

Patch Changes

  • #1821 5629d46 Thanks @dqbd! - feat(sdk): allow client-side filtering of events when joining a stream.

  • #1897 78743d6 Thanks @bracesproul! - fix: cannot convert undefined or null to object error in useStream

langgraph@1.0.16
