In this module, you will learn how to build a retrieval augmented generation (RAG) application using FastAPI, DSPy, and Weaviate. Your application will have a React frontend that you will create.
The adventure begins...
A quick overview of the architecture of the audio AI assistant you are going to build, as an extra of this course.
In this video, I will guide you step by step on how to set up a FastAPI API, and add DSPy service to it.
Create a basic file upload route for your application to handle document uploads.
Enhance your file upload route with error handling and better user feedback.
Learn how to parse plain text documents and extract meaningful content for your RAG app.
Incorporate Optical Character Recognition (OCR) to parse and retrieve data from PDF documents.
Set up and manage a Weaviate vector store to efficiently store and retrieve vectorized data.
Implement background tasks in your FastAPI app to improve performance and handle time-consuming operations.
Build a React frontend for your RAG application, enabling users to interact with the system through a web interface.
A quick overview of the architecture of the audio AI assistant you are going to build.
To create the frontend folder: npx create-react-app frontend
Install dependencies:
npm install styled-components
npm install --save-dev @babel/plugin-proposal-private-property-in-object
npm install react-router-dom@latest
npm install uuid
To create the backend follow these instructions:
mkdir backend
npm init -y
npm install express multer openai
npm install dotenv
npm install uuid
npm install cors
add your OPENAI_API_KEY in the .env file
Learn to build a comprehensive full-stack Retrieval Augmented Generation (RAG) application from scratch using cutting-edge technologies like FastAPI, Weaviate, DSPy, and React. In this hands-on course, you will master the process of developing a robust backend with FastAPI, handling document uploads and parsing with DSPy, and managing vector data storage using Weaviate. You'll also create a responsive React frontend to provide users with an interactive interface. By the end of the course, you'll have the practical skills to develop and deploy AI-powered applications that leverage retrieval-augmented generation techniques for smarter data handling and response generation.
