dev-utils-plus

Type-safe utility functions for JavaScript/TypeScript: string, array, object, date, validation, crypto, format, math. Clean APIs, strict types, zero runtime dependencies, and tree-shakable builds.

Features

• Type-safe utilities: built with TypeScript, .d.ts included
• Zero dependencies: lightweight and fast
• Tree-shakable: import only what you need
• Node + Browser: works across environments
• Broad coverage: string, array, object, date, validation, crypto, format, math
• Lodash alternative: modern, modular helper functions
• Enhanced error handling: comprehensive input validation with descriptive error messages
• Improved performance: optimized algorithms and better memory usage
• Rich documentation: detailed JSDoc comments with examples for every function

Install

npm i dev-utils-plus
# or
pnpm add dev-utils-plus
# or

  // string
  capitalize, 
  toCamelCase,
  toKebabCase,
  toSnakeCase,
  toPascalCase,
  escapeHtml,
  cleanWhitespace,
  generateRandomString,

  // array
  unique, 
  shuffle,
  chunk,
  flatten as flattenArray,
  take,
  drop,
  max,
  min,

  // object
  deepClone, 
  deepMerge,
  pick,
  omit,
  get,
  set,
  flattenObject,

  // date
  formatDate,
  startOfDay,
  endOfDay,
  addDays,

  // format
  formatCurrency,
  formatFileSize,
  formatDuration,

  // math
  clamp,
  median,
  distance,
  binomial,
  randomInt,

  // validation
  isValidEmail,

  // crypto
  generateUUID,
  toBase64,
  fromBase64
} from 'dev-utils-plus';

// Enhanced string utilities
capitalize('hello world'); // "Hello world"
toCamelCase('hello-world'); // "helloWorld"
toPascalCase('hello-world'); // "HelloWorld"
escapeHtml('<div>Hello & world</div>'); // "&lt;div&gt;Hello &amp; world&lt;/div&gt;"
cleanWhitespace('  hello   world  '); // "hello world"

// Enhanced array utilities
unique([1, 2, 2, 3]); // [1, 2, 3]
take([1, 2, 3, 4, 5], 3); // [1, 2, 3]
drop([1, 2, 3, 4, 5], 2); // [3, 4, 5]
max([1, 5, 3, 9, 2]); // 9

// Enhanced math utilities
clamp(10, 0, 5); // 5
median([1, 2, 3, 4]); // 2.5
distance(0, 0, 3, 4); // 5
binomial(5, 2); // 10
randomInt(1, 10); // Random integer between 1-10

// Existing utilities work the same
formatCurrency(1234.56, 'USD'); // "$1,234.56"
isValidEmail('user@example.com'); // true
