Build a sleek chat interface for your AI prototype using Vite and Lit, while managing infrastructure with Bicep and Azure Developer CLI. This quest enhances UX, streamlines deployment, and sets the stage for advanced AI features, making your app scalable and user-friendly. Bullet points:

Quest 3: Build a Sleek Chat Interface for Your AI Prototype
If you’ve been tinkering with AI prototypes, you know that a simple console isn’t enough. Microsoft’s latest Quest 3 tutorial shows how to add a polished chat UI using modern tools like Vite and Lit. This step transforms your AI from a basic prototype into an interactive experience anyone can use.
What’s New in Quest 3?
This quest focuses on user experience, making your AI prototype not just functional but friendly and engaging. You’ll build a chat interface that feels like a real app, complete with message rendering and chat state management.
Alongside the UI, you’ll get hands-on with infrastructure-as-code using Bicep and streamline deployment with the Azure Developer CLI (azd). These tools help keep your project clean, scalable, and ready for future upgrades.
“A sleek UI turns a console prototype into something playable by anyone.”
Major Updates and Tools You’ll Explore
Vite + Lit for Lightning-Fast UIs
Vite offers blazing-fast development builds and hot reloads. Paired with Lit, it lets you create reactive web components effortlessly. Your custom <chat-ui>
component will handle chat messages smoothly, whether connected to a mock or real AI backend.
Azure Developer CLI (azd)
The Azure Developer CLI ties your frontend, backend, and infrastructure into one seamless workflow. Just run azd up
to spin up your app environment instantly—no complex setup required.
Infrastructure as Code with Bicep
Bicep simplifies writing infrastructure templates. You’ll provision Azure Static Web Apps and App Service resources declaratively, ensuring your app is scalable and DevOps-ready from the start.
“Using Bicep & azd ensures your app can scale and deploy cleanly later on.”
Why This Quest Matters for AI Builders
First impressions count. A user-friendly chat UI invites more users to interact with your AI prototype. Plus, this quest lays the groundwork for advanced features like retrieval-augmented generation (RAG) and memory integration.
By managing infrastructure as code, you also future-proof your app for smooth deployment and scaling. This is crucial for turning prototypes into production-ready solutions.
