react-tailwind-grid-viewer

A React component that provides a visual overlay for displaying and debugging grid layouts in your application, defined by tailwind classes.

Features

• Visualize grid columns across different breakpoints
• Toggle visibility with Shift + G on your keyboard
• Customizable colors and opacity
• Configurable grid settings for different breakpoints

Installation

npm i react-tailwind-grid-viewer

or

yarn add react-tailwind-grid-viewer

Usage

import GridViewer from "react-tailwind-grid-viewer";
<GridViewer color="bg-cyan-500" />;

It's a good idea to avoid rendering the component in production, but it's up to you.

{
  process.env.NODE_ENV !== "production" && <GridViewer color="bg-cyan-500" />;
}

Keyboard Shortcut

Press Shift + G to toggle the grid overlay visibility.

FAQ

Q: I can only see the column numbers, but not the grid lines.

A: Make sure you set color to a existing background color class in from your tailwind config e.g. bg-gray-500.

Q: Can I use GridViewer with other CSS frameworks?

A: While GridViewer is designed to work seamlessly with Tailwind CSS, you could use it with other frameworks by providing appropriate class names in the grid configuration.

Q: How can I change the keyboard shortcut?

A: Currently, the keyboard shortcut is not customizable.

Q: Does GridViewer affect my application's performance?

A: GridViewer is designed to have minimal impact on performance. It only renders when visible and uses CSS for most of its functionality. However, it's recommended to remove or disable it in production builds.
