tailwind-upgrade

To upgrade Tailwind CSS to v4, you need to migrate your configuration from tailwind.config.js to CSS-first @theme directives, adapt to the Oxide engine, and run visual regression tests to ensure UI stability. This process automates that transition safely.

The Tailwind CSS v4 Oxide engine migration process involves assessing project risks, converting design tokens and utilities to @theme directives, and benchmarking performance against Oxide targets. It orchestrates the shift from older Tailwind versions while ensuring compatibility with existing dependencies.

Yes, upgrading to Tailwind CSS v4 requires converting your tailwind.config.js file to CSS-first configuration using @theme directives. This migration handles the shift automatically, ensuring your design tokens and utilities integrate smoothly into the new Oxide engine structure.

You benchmark frontend performance after a Tailwind CSS upgrade by measuring the build and runtime metrics against the Oxide engine targets. This migration process includes performance benchmarking to ensure the new v4 architecture meets your expected speed and efficiency improvements.

Yes, you can integrate visual regression testing during a Tailwind CSS v4 migration. The upgrade process includes integration with regression tooling to catch unintended visual and functional changes, ensuring your UI design remains stable across the transition.

Migrating an established project to Tailwind CSS v4 carries the risk of dependency conflicts and unintended UI changes from the Oxide engine shift. The migration manages this risk assessment, but complex project structures may require careful manual review of converted design tokens and utilities.
