Opening your Mini App
Mini Apps are built using Web Technologies like HTML, CSS, and JavaScript. This means you can view your Mini App in a web browser just like any other website.
Using web technologies helps us to quickly see how our app looks like without needing to constantly check it inside the World App.
And… how do I do that?
To view your Mini App in a browser, follow these steps:
Locate the mini-app folder
Search for the my-app folder you created earlier. This is where our Mini App files are stored. If you followed the previous steps, it should be where you ran the create-world-app command.
Start the development server
Open a terminal in the my-app folder. You can do this by right-clicking the folder and selecting “Open in Terminal” or using your code editor’s terminal feature.
And run the following command to start the development server:
npm run devOpen your browser
Navigate to http://localhost:3000  in your web browser. This is where your Mini App should be running
Tada 🎉
You should now see something like this:
Hey. This is a great milestone! You have to feel proud if it’s your first time in the Mini App world. And even if it’s not, you are still doing great! Keep it going! 🚀
