getCurrentTaskInput<T = unknown>(config: LangGraphRunnableConfig<Record<string, any>>): T| Name | Type | Description |
|---|---|---|
config | LangGraphRunnableConfig<Record<string, any>> | Optional LangGraphRunnableConfig to read the task
input from. Provide this when running in an environment without
|
A helper utility function that returns the input for the currently executing task.
Note: When called without arguments, this relies on node:async_hooks /
AsyncLocalStorage, which is available in many JavaScript environments
(Node.js, Deno, Cloudflare Workers) but not in web browsers. In environments
without AsyncLocalStorage support, pass the config that your node/tool
function receives directly, e.g. getCurrentTaskInput(config).
Tip: Inside a tool run by a ToolNode, prefer reading graph state from
runtime.state on the second tool argument (typed as ToolRuntime from
@langchain/core/tools). It works in every runtime, including web browsers.
