Functions

func CreateEmbeddingsStepObject

func CreateEmbeddingsStepObject(runtime *goja.Runtime, loop *eventloop.EventLoop, provider steps.Step[string, []float32]) (*goja.Object, error)

Example usage with embeddings step

func CreateStepObject

func CreateStepObject[T any, U any](
	runtime *goja.Runtime,
	loop *eventloop.EventLoop,
	step steps.Step[T, U],
	inputConverter func(goja.Value) T,
	outputConverter func(U) goja.Value,
) (*goja.Object, error)

CreateStepObject creates a JavaScript object wrapping a Step with Promise, blocking and callback APIs

func NewJSLambdaStep

func NewJSLambdaStep[T any, U any](
	runtime *goja.Runtime,
	fn goja.Callable,
	inputConverter func(T) goja.Value,
	outputConverter func(goja.Value) (U, error),
) steps.Step[T, U]

Helper to create a LambdaStep from a JavaScript function

func RegisterConversation

func RegisterConversation(runtime *goja.Runtime) error

RegisterConversation registers the Conversation constructor in the JavaScript runtime

func RegisterEmbeddings

func RegisterEmbeddings(runtime *goja.Runtime, globalName string, provider embeddings.Provider, loop *eventloop.EventLoop) error

RegisterEmbeddings registers the embeddings functionality in the given Goja runtime

func RegisterFactory

func RegisterFactory(runtime *goja.Runtime, loop *eventloop.EventLoop, stepSettings *settings.StepSettings) error

RegisterFactory registers the chat step factory functionality in the JavaScript runtime

func RegisterStep

func RegisterStep[T any, U any](
	runtime *goja.Runtime,
	loop *eventloop.EventLoop,
	name string,
	step steps.Step[T, U],
	inputConverter func(goja.Value) T,
	outputConverter func(U) goja.Value,
) error

RegisterStep is kept for backward compatibility
