Code Generation

Twerge provides powerful code generation capabilities, allowing you to generate Go code from class mappings for improved performance and type safety.

The Problem

When using shortened class names in a production environment, you need:

1. A way to consistently map original Tailwind classes to short names
2. Fast lookups without runtime overhead
3. Type safety and compiler checks
4. Integration with build processes

How Twerge Solves It

Twerge can generate Go code that contains the class mappings, providing compile-time checking and improved performance:

package main

import "github.com/conneroisu/twerge"

func main() {
	if err := twerge.CodeGen(
		twerge.Default(),
		"classes/classes.go",
		"input.css",
		"classes/classes.html",
		views.View(),
	); err != nil {
		panic(err)
	}
}

Benefits of Code Generation

Using generated code provides several advantages:

1. Performance - No runtime hash computation or map lookups
2. Type Safety - Compile-time checking of class names
3. Smaller Binary - Compiled code can be optimized by the Go compiler
4. Build-time Validation - Issues are caught during the build process
5. IDE Support - Auto-completion and refactoring support in IDEs
