Export ClassValue Type for Better Type Consistency and Reduced Imports

[msneves13]

Hi CVA team,

I am using the library in an Angular project and encountered an issue with type definitions. Specifically, the library does not export the ClassValue.

Here is a simplified example:

import { Directive, Input, computed, input, signal } from '@angular/core';
import { type ButtonVariants, buttonVariants } from './button.cva';

import { type ClassValue, clsx } from 'clsx';

@Directive({
	standalone: true,
	host: {
		'[class]': '_computedClass()',
	},
})
export class ButtonDirective {
	public readonly userClass = input<ClassValue>('', { alias: 'class' });
	private readonly _settableClass = signal<ClassValue>('');

	protected _computedClass = computed(() =>
		cx(
			buttonVariants({ btnType: this._btnType(), btnSize: this._btnSize(), btnColor: this._btnColor() }),
			this._settableClass(),
			this.userClass(),
		),
	);

	setClass(value: ClassValue) {
		this._settableClass.set(value);
	}

	private readonly _btnType = signal<ButtonVariants['btnType']>('basic');
	@Input()
	set btnType(type: ButtonVariants['btnType']) {
		this._btnType.set(type);
	}

	private readonly _btnSize = signal<ButtonVariants['btnSize']>('standard');
	@Input()
	set btnSize(size: ButtonVariants['btnSize']) {
		this._btnSize.set(size);
	}

	private readonly _btnColor = signal<ButtonVariants['btnColor']>('primary');
	@Input()
	set btnColor(color: ButtonVariants['btnColor']) {
		this._btnColor.set(color);
	}
}

CVA already provides a wrapper for clsx, which is very useful. However, the lack of exported type definitions like ClassValue means that we need to import these types from clsx directly. This leads to:

1. Increased Imports: Having to import types from multiple libraries increases the complexity and size of the import statements.

2. Type Consistency: Exporting ClassValue directly from CVA would ensure consistent types across the codebase, reducing potential type mismatches and making the code easier to maintain.

Would it be possible for the library to export the ClassValue type and other relevant types?

Thank you!
