AIDK API Reference / aidk/content / StreamChunkType

Enumeration: StreamChunkType

Defined in: packages/shared/src/streaming.ts:580

Deprecated

Use StreamEvent types instead. StreamChunkType was replaced by discriminated union types like ContentDeltaEvent, MessageEndEvent, etc. The new StreamEvent union provides better type safety with proper discriminated unions.

Migration guide:

StreamChunkType.CONTENT_DELTA -> event.type === "content_delta" (ContentDeltaEvent)
StreamChunkType.MESSAGE_END -> event.type === "message_end" (MessageEndEvent)
StreamChunkType.TOOL_CALL -> event.type === "tool_call" (ToolCallEvent)
etc.
