yarn add ultra-utils
# or
pnpm add ultra-utils

📖 Complete Usage Guide

Ultra Utils provides two main ways to use the library: JavaScript/TypeScript imports and Terminal/CLI commands. Choose the method that best fits your workflow.

🔧 JavaScript/TypeScript Usage

Method 1: Named Imports (Recommended for Tree Shaking)

// Import specific functions you need
import { slugify, camelCase, sha256, randomColor, addDays } from 'ultra-utils';

// Use the functions
const slug = slugify('Hello World!');           // 'hello-world'
const camel = camelCase('hello-world');         // 'helloWorld'
const hash = sha256('password');                // 'ef92b778bafe771e89245b89ecbc08a44a4e166c06659911881f383d4473e94f'
const color = randomColor();                    // '#a3d5f1'
const futureDate = addDays(new Date(), 30);    // Date 30 days from now

Method 2: Category Imports

// Import by utility category
import { stringUtils, cryptoUtils, colorUtils, dateUtils } from 'ultra-utils';

// Use category functions
stringUtils.slugify('Hello World!');
cryptoUtils.sha256('password');
colorUtils.randomColor();
dateUtils.addDays(new Date(), 30);

Method 3: Default Import (All Functions)

// Import everything (larger bundle size)
import utils from 'ultra-utils';

// Use any function
utils.slugify('Hello World!');
utils.sha256('password');
utils.randomColor();
utils.addDays(new Date(), 30);

Method 4: CommonJS (Node.js)

// CommonJS require syntax
const { slugify, sha256, randomColor } = require('ultra-utils');

// Or require everything
const utils = require('ultra-utils');
utils.slugify('Hello World!');

TypeScript Support

import { slugify, RandomColorFormat, DateFormat } from 'ultra-utils';

// Full type safety and IntelliSense
const slug: string = slugify('Hello World');
const color = randomColor('hsl' as RandomColorFormat);
const formatted = formatDate(new Date(), 'YYYY-MM-DD' as DateFormat);
