In this workshop, we will build a chatbot based on OpenAI language models and implementing the Retrieval Augmented Generation (RAG) pattern. You'll use Fastify to create a Node.js service that leverage OpenAI SDK and LangChain to build a chatbot that will answer questions based on a corpus of documents, as well as a website to test it.

You can also use the Dev Containers extension for VS Code to work locally using a ready-to-use dev environment.

This project is structured as monorepo and makes use of NPM Workspaces.

npm install
npm start

This command will start the frontend and backend services. For these services to work, you need to have a .env file at the root of the project with at least the following content:

AZURE_SEARCH_SERVICE=<your_azure_cognitive_search_instance_name>
AZURE_OPENAI_URL=<you_openai_instance_url>

The application will then be available at http://localhost:8000.

npm run docker:build

This command will build the container images for all services.

azd auth login
azd up

This commands will first ask you to log in into Azure. Then it will provison the Azure resources, package the services and deploy them to Azure.

This workshop is based on the enterprise-ready sample ChatGPT + Enterprise data with Azure OpenAI and Cognitive Search:

• JavaScript version
• Python version
• Java version
• C# version
