pretty-class v1.0.2

Pretty Class

pretty-class is a lightweight utility package designed to simplify the process of generating dynamic class names in JavaScript and TypeScript applications. It provides a flexible and intuitive way to conditionally combine class names based on different input types.

Installation

To install pretty-class, use npm or yarn:

npm install pretty-class

or

yarn add pretty-class

Usage

Importing the Package

import prettyClass from 'pretty-class';

Function Signature

export type prettyClassTypes = string | Record<string, boolean> | prettyClassTypes[] | undefined | null | false;
const prettyClass: (...args: prettyClassTypes[]) => string;

Parameters

• args: A variable number of arguments of type prettyClassTypes. Each argument can be:
  • A string: Adds the string directly to the class list.
  • An object with keys as class names and values as boolean: Includes the key if the value is true.
  • An array: Recursively processes the array elements.
  • undefined, null, or false: Ignored in the output.

Returns

• A string containing the concatenated class names.

Example Usage

Basic String Input

const result = prettyClass('class1', 'class2');
console.log(result); // Output: "class1 class2"

Conditional Classes

const result = prettyClass({ 'class1': true, 'class2': false, 'class3': true });
console.log(result); // Output: "class1 class3"

Nested Arrays

const result = prettyClass(['class1', { 'class2': true }, ['class3', { 'class4': false }]]);
console.log(result); // Output: "class1 class2 class3"

Mixed Inputs

const result = prettyClass('class1', { 'class2': true }, ['class3', null, false]);
console.log(result); // Output: "class1 class2 class3"

Benefits

• Lightweight: Minimal code footprint.
• Flexible: Supports various input types.
• Recursive: Handles nested arrays gracefully.
• Typed: Fully typed for TypeScript users.
