AzureFeeds

In this quest, you’ll give your Gen AI prototype a polished chat interface using Vite and Lit. Along the way, you’ll also manage application infrastructure with Bicep and Azure Developer CLI (azd), making your prototype more structured and ready for deployment.

This step is all about UX, making your AI prototype not just functional, but interactive and user-friendly.

🔧 What You’ll Build

By the end of this quest, you’ll have:

• A chat UI built with Vite and Lit 


• A structured codebase with infrastructure-as-code (IaC) using Bicep 


• Seamless local deployment workflow using the Azure Developer CLI (azd) 

This UI lets users chat with your prototype as if it were a real app.

💡 Why This Quest Matters

• First impressions count – A sleek UI turns a console prototype into something playable by anyone. 


• Scaffolding for more – Once your UI is ready, you can plug in advanced features like RAG and memory. 


• Clean infrastructure – Using Bicep & azd ensures your app can scale and deploy cleanly later on.

🚀 What You’ll Need

1. ✅ A GitHub account


2. ✅ Visual Studio Code installed


3. ✅ Node.js installed


4. ✅An Azure subscription. Use the free trial if you don’t have one, or Azure for Students if you are a student.


5. ✅ Azure Developer CLI installed

🛠️ Concepts You’ll Explore

⚡️Vite + Lit = Fast UIs with Modern web components

In this quest, you’ll use Vite for lightning-fast dev builds and hot reloads, paired with Lit to build sleek, reactive web components. You’ll integrate a custom built with Lit to render messages and manage chat state—plug in a mock or real AI backend and you’re good to go. Fast, modular, and extensible.

💻 Azure Developer CLI (azd)

ties your app’s frontend, backend, and infrastructure into one command-line flow. You’ll use it to instantly spin up a working app environment without writing the setup from scratch—just and go!

🏗️ Infrastructure as Code with Bicep

Bicep lets you write your infra as code using simple, declarative templates. In this quest, you’ll use Bicep to provision services like Azure Static Web Apps and App Service, ensuring everything is scalable, consistent, and DevOps-ready.
