LangBot Day 6: Output Parsers — Transforming Raw Responses into Usable Data
reading time: 20 minutes
Recap: On Day 5, LangBot started returning typed objects — every response is now a LangBotResponse with .message, .mood, and .confidence. That is great when you need structured metadata. But structured output is not always the right tool. Sometimes you just want a clean string. Sometimes you want a parsed list. Today we add output parsers — lightweight LCEL components that transform raw AIMessage output into exactly the shape you need.
