Quickstart Guide: Build a Power Apps Code App from Scratch Using Vite

Ready to build a fully custom Power Apps code app from the ground up? In this quickstart guide, you'll learn exactly how to scaffold a blank app using Vite and transform it into a fully functional Power Apps code app — step by step, no fluff. Whether you're a seasoned developer or just getting started with the Power Platform, this guide gives you a clean, practical foundation to build on.

Power Apps code apps give developers the freedom to build rich, modern experiences using standard web technologies while still leveraging the full power of the Microsoft ecosystem. If you've been looking for a way to break free from the canvas app limitations and write real code, this is your starting point.

What You'll Need Before You Start

Before diving in, make sure you have the following prerequisites in place:

Not sure if your environment is set up correctly? Our team at CRMONCE offers expert consulting services to help you get your Power Platform environment production-ready from day one.

Step 1: Scaffold a Blank App with Vite

The first step is creating a new blank project using Vite. Open your terminal and run the following command:

npm create vite@latest my-code-app -- --template vanilla-ts

This generates a clean TypeScript project with a minimal structure. Navigate into the project folder and install dependencies:

cd my-code-app
npm install

Step 2: Configure the Project for Power Apps

Once your Vite project is scaffolded, you'll need to configure it to work as a Power Apps code app. This involves:

Step 3: Connect to the Power Platform

With your project configured, the next step is connecting it to your Power Platform environment using the PAC CLI:

pac auth create --url https://your-environment.crm.dynamics.com

Once authenticated, you can push your app to the environment and begin testing directly inside Power Apps Studio.

Step 4: Build and Package Your Code App

Before deploying, build your project for production:

npm run build

Then use the PAC CLI to package and push the app:

pac canvas pack --sources ./src --msapp ./dist/MyCodeApp.msapp

Your app is now packaged and ready to be imported into your Power Apps environment.

Step 5: Test and Iterate

Once uploaded, open the app in Power Apps Studio and run it in preview mode. Use browser developer tools for debugging, just as you would with any standard web application. The power of code apps is that your standard web development skills transfer directly.

Why Build Power Apps Code Apps?
