A Rust clone targeting Tailwind CSS v4.1 behavior.
ironframe is an OSS project that re-implements Tailwind CSS v4.1-equivalent features in Rust. It separates scanner, generator, config, and CLI crates for fast iteration in learning and prototyping.
JIT Build Loop
Comes with scan/build/watch commands so you can regenerate CSS quickly as templates change.
Tailwind-style Input
Supports workflows around @import tailwindcss, @source, @apply, and split imports.
Modular Rust Design
Split into core/scanner/generator/config/cli crates for easier extension and experimentation.
Setup and Basic Usage
After cloning the repository, install the CLI (or run through cargo) and start with scan/build to verify class extraction and CSS output.
Setup
cargo install --path crates/cli
CLI Example
# 1) Extract class candidates
ironframe scan "src/**/*.{html,tsx}"
# 2) Build CSS once
ironframe build --out dist/app.css "src/**/*.{html,tsx}"
# 3) Build with input CSS and config
ironframe build --input-css src/app.css -c tailwind.toml --out dist/app.css "src/**/*.{html,tsx}"
# 4) Rebuild on file changes
ironframe watch --out dist/app.css "src/**/*.{html,tsx}"
Important Note
ironframe is a learning/prototyping implementation targeting Tailwind CSS v4.1-equivalent behavior so validate compatibility and output differences against your existing CSS before production use.
