Installation

npm install packagename

Quick Start

const { validate, format, transform } = require('packagename');

// Validate data structures
const isValid = validate.object({
  name: 'string',
  age: 'number',
  email: 'email'
}, userData);

// Format dates across timezones
const formatted = format.date(new Date(), 'YYYY-MM-DD', 'America/New_York');

// Transform data pipelines
const result = transform.pipe(
  data,
  transform.filter(x => x.active),
  transform.map(x => x.value),
  transform.reduce((a, b) => a + b, 0)
);
