Piyush Garg - Building AI Agent from Scratch with OpenAI and Postgres

The video builds on a previous tutorial by creating a real-world AI agent using a to-do application. The focus is on integrating AI with a real database and ORM (Object-Relational Mapping) to perform CRUD operations. The tutorial uses PostgreSQL for the database and Drizzle ORM for managing database interactions. The AI agent is designed to understand natural language commands to manage to-do tasks, demonstrating how AI can interact with databases securely. The video also covers setting up a Docker environment for PostgreSQL, creating a schema for to-do tasks, and using OpenAI's API for natural language processing. The tutorial provides a step-by-step guide to setting up the environment, writing the necessary code, and testing the AI agent's functionality. The practical application shows how AI can be used to automate task management, providing a foundation for more complex AI-driven applications.

Key Points:

  • Use PostgreSQL and Drizzle ORM to manage database operations for AI agents.
  • Integrate OpenAI's API to process natural language commands for task management.
  • Set up a Docker environment to run PostgreSQL securely and efficiently.
  • Create a schema for to-do tasks to perform CRUD operations using AI.
  • Demonstrate AI's capability to automate and manage tasks through natural language processing.

  • Drizzle ORM requires the installation of Drizzle Kit and Drizzle Studio to facilitate development.
  • Add a command in your package.json to open Drizzle Studio with 'npm run studio' for streamlined access.
  • Key CRUD operationsโ€”create, read, update, and deleteโ€”are implemented using Drizzle ORM, focusing on a 'todo' table.
  • Functions such as 'getAllTodos', 'createTodo', and 'searchTodo' are used to interact with the database.
  • 'getAllTodos' retrieves all entries from the 'todo' table efficiently using asynchronous database calls.
  • 'createTodo' adds a new record into the 'todo' table, simplifying the process to just needing a string input for the 'todo'.
  • The flexibility of Drizzle ORM allows for file organization in either a single consolidated file or across multiple files for better management.
  • For example, using 'getAllTodos', developers can quickly fetch all todos, enhancing data retrieval processes.
