    Input values for the chain run.

  • Optional config: BaseCallbackConfig

    Optional configuration for the Runnable.

  Returns Promise<ChainValues>

  Promise that resolves with the output of the chain run.

prepOutputs

• prepOutputs(inputs, outputs, returnOnlyOutputs?): Promise<Record<string, unknown>>

• Parameters

  • returnOnlyOutputs: boolean = false

  Returns Promise<Record<string, unknown>>

run

• run(input, config?): Promise<string>

• Parameters

  • input: any

  • Optional config: BaseCallbackConfig | Callbacks

  Returns Promise<string>

serialize

• serialize(): SerializedBaseChain

• Return a json-like object representing this chain.

  Returns SerializedBaseChain

Static deserialize
