Assets

Static files such as images and stylesheets can be placed in "assets/" folder of the project. These files can be referenced within your app.

# Assets are copied during the build process.

Any files placed within the `assets/` folder at runtime will not be available to the app
when running in production mode. The `assets/` folder should only be used for static files.

Referencing Assets

To reference an image in the "assets/" simply pass the relative path as a prop.

For example, you can store your logo in your assets folder:

assets
└── Reflex.svg

Then you can display it using a rx.image component:

rx.image(src="/Reflex.svg", width="5em")

Always prefix the asset path with a forward slash `/` to reference the asset from the root of the project,
or it may not display correctly on non-root pages.

Favicon

The favicon is the small icon that appears in the browser tab.

You can add a "favicon.ico" file to the "assets/" folder to change the favicon.
