cx(...classes: any): string

The cx function is a utility to conditionally concatenate class names into a single string. This is particularly useful when working with CSS in JavaScript frameworks or libraries, such as React, where class names might be dynamic.

Installation

npm install @architecturex/utils.cx

Usage

import cx from '@architecturex/utils.cx'

Call the cx function with any number of arguments to concatenate them into a single string of class names:

const className = cx('class1', 'class2', condition && 'class3')

Arguments

The cx function can accept multiple arguments of various types:

• String: The string is directly added to the result.
• Number: Numbers are converted to strings and added to the result.
• Array: Nested arrays are flattened. Each element in the array is processed based on its type (can be any of the supported types).
• Object: Object properties that have truthy values are added to the result. For custom objects with a custom toString method that doesn't rely on native code, the toString method's output is added.

Examples

1. Basic strings:

cx('class1', 'class2') // "class1 class2"

2. Conditional classes:

const isActive = true

cx('class1', isActive && 'active') // "class1 active"

3. Arrays

cx(['class1', 'class2', ['nested1', 'nested2']]) // "class1 class2 nested1 nested2"

4. Objects:

const buttonStyles = {
  btn: true,
  'btn-primary': true,
  'btn-disabled': false
}

cx(buttonStyles) // "btn btn-primary"
