CSS Modules for Rust

css_mod

CSS Modules implementation for Rust web applications

A CSS Module is a CSS file in which all class names and animation names are scoped locally by default.

Features

This is currently incomplete implementation of CSS Modules spec, as it only supports the vital features.

• Local scoping for names
  • Classes
  • Animations
  • Grid lines/areas
  • @counter-style
• :local() / :global()
• composes
• url() / @import

Usage

1. Add this crate as a regular and build dependency:

   # Cargo.toml
   
   [dependencies]
   css_mod = "0.1.0"
   
   [build-dependencies]
   css_mod = "0.1.0"

2. Create build script and call compiler:

   // build.rs
   
   fn main() {
       css_mod::Compiler::new()
           .add_modules("src/**/*.css").unwrap()
           .compile("assets/app.css").unwrap();
   }

3. Call init somewhere early in program execution:

   // src/main.rs
   
   fn main() {
       css_mod::init!();
   }

4. Finally get name mapping for CSS module:

   // src/my-component.rs
   
   let css = css_mod::get!("my-component.css");
   let global_class_name = css["local-class-name"]; // my-component__local-class-name__0
