WebContainer lets you run your app and see it working. If your app has multiple parts (like a website and a backend), you can easily switch between them.

What is WebContainer?

Think of WebContainer like a mini computer inside CodinIT. It runs your code and shows you what it looks like, just like opening a website in your browser.

How to Use It

Switching Between Parts

When your app is running, you might see different “ports” (think of them as different doors to your app). You can click a dropdown to switch between them.
  • Click the port number to see all available parts
  • Select the one you want to view
  • Your preview updates instantly

When You Need Multiple Parts

Some apps have different pieces that work together:
  • Website - What users see and click on
  • Backend - The part that handles data and logic
  • Tools - Extra helpers for testing or building
You can view each part separately to make sure everything works correctly. Once you pick a part to view:
  • Type URLs in the address bar to visit different pages
  • Click the refresh button to reload
  • Open in a new tab to see it in your regular browser
Easy Switching: CodinIT automatically finds all the running parts of your app. Just pick the one you want to see from the dropdown menu.
