About this page
This page explains how to implement the ReAct (Reason+Act) pattern from scratch using only TypeScript, without any frameworks. ReAct is an AI agent pattern where LLMs alternate between 'reasoning' and 'acting' steps to solve problems progressively. The article demonstrates this through a practical example of an npm package selection agent using two tools: search and get_info. It illustrates how the Reason→Action→Observation loop works by showing actual code implementation.
