FAQPage Schema
How do I open my frontend in the browser using a custom VITE_PORT?▼

To open your frontend in the browser, the system reads the VITE_PORT from your .env file and launches the default browser. It defaults to port 5173 if VITE_PORT is not specified.

What is the default port used to open a Vite frontend application?▼

The default port to open a Vite frontend application is 5173. This is used automatically when the VITE_PORT environment variable is not defined in your .env file.

How to quickly preview a local React app in the default browser after startup?▼

Quickly preview a local React app by triggering the system's default open mechanism. It reads the configured VITE_PORT to launch the exact development URL in your default browser.

Does the browser open command require a specific .env file configuration?▼

The browser open command does not strictly require a .env file configuration. It looks for VITE_PORT in the .env file, but automatically falls back to port 5173 if the file or variable is missing.

Can I use this to open a frontend for QA workflows on a different port?▼

Yes, you can use this for QA workflows on a different port. Simply set the desired port number as the VITE_PORT variable in your .env file, and the browser will open that specific URL.
