In this project, we will build a full stack app that works similar to ChatGPT and answers prompts and keeps the context throughout the conversation. We will use Vue.js with Pinia for state management, Node and Express on the backend with TypeScript. Stream for the chat featrues and a Neon PostgreSQL database to store users and chat logs.
