Tinita

Modern TypeScript utility library with tree-shaking support.

Installation

npm install tinita
# or
yarn add tinita
# or
pnpm add tinita

Requirements

• TypeScript >= 5.0 (recommended)
• No runtime dependencies

Features

• Zero dependencies: No external runtime dependencies
• Tree-shakeable: One file = one function for optimal bundle size
• TypeScript-first: Full type safety with type guards and strict mode
• Modern build: ESM and CJS support with subpath exports
• Thoroughly tested: Comprehensive test coverage
• Framework-agnostic: Works with any JavaScript framework or vanilla JS

What's Included

Tinita provides a comprehensive collection of utilities organized by domain:

• Type guards & validators: Type-safe runtime checks for numbers, strings, objects, arrays, and more
• File utilities: File name handling, size formatting, duplicate detection
• UUID generation: Cross-platform UUID v4 with automatic fallbacks
• String utilities: Manipulation, validation, and transformation helpers
• Array utilities: Filtering, mapping, and data structure operations
• Object utilities: Deep cloning, merging, path access
• Date utilities: Formatting, parsing, and manipulation

All utilities follow consistent patterns:

• Type guards return value is Type for TypeScript narrowing
• Pure functions with no side effects
• Minimal API surface for each utility
• Comprehensive edge case handling

Usage

Barrel Import (Convenient)

Import multiple utilities from the main entry point:

import { isNumber, isPositive, generateUUID } from 'tinita';

Subpath Import (Optimal Tree-Shaking)

Import directly from utility paths for guaranteed minimal bundle size:

import { generateUUID } from 'tinita/uuid/generateUUID';
import { fileSize } from 'tinita/file/fileSize';

Recommendation: Use subpath imports for production to ensure optimal bundle size regardless of bundler capabilities.

TypeScript Support

All utilities are fully typed with TypeScript.

Environment Support

tinita works in any JavaScript environment:

• ✅ Node.js (v18+)
• ✅ Browser (all modern browsers)
• ✅ Deno
• ✅ Bun
• ✅ Edge runtimes (Cloudflare Workers, Vercel Edge Functions, etc.)

Testing

To run tests:
