OptiKit

The Zero-Dependency, Ultra-Lightweight Utility Engine for Modern JavaScript & TypeScript.

OptiKit is a zero-dependency, ultra-lightweight, and fully tree-shakeable JavaScript/TypeScript utility engine designed to replace legacy monolithic packages like Lodash, Moment, and Ramda. Built natively in TypeScript, it ships 38 hand-optimized modules containing 434+ functions in both ES Modules (.mjs) and CommonJS (.js) formats.

Key Highlights

• ⚡ 16.0 KB Minified + Gzipped
• 🛡️ 100/100 Security & Vulnerability Score (Socket Security Verified)
• 📦 0 External Dependencies — Immune to supply-chain attacks
• 🌳 100% Tree-Shakeable — Ships with "sideEffects": false
• 🎯 434+ Isomorphic Utilities across 38 dedicated domain modules
• 🧪 426 Unit Tests with 100% passing test coverage

Code Examples

1. String Casing & Formatting

import { slugify, truncate, escapeHtml } from '@dev_x_mohit/opti-kit';

slugify('OptiKit Zero Dependency!'); // "optikit-zero-dependency"
truncate('Building high performance web apps', 18); // "Building high..."
escapeHtml('<h1>Hello World</h1>'); // "&lt;h1&gt;Hello World&lt;/h1&gt;"

2. Array & Object Operations

import { chunk, unique, groupBy, deepClone, deepMerge } from '@dev_x_mohit/opti-kit';

chunk([1, 2, 3, 4, 5, 6], 2); // [[1, 2], [3, 4], [5, 6]]
unique([1, 1, 2, 3, 3]); // [1, 2, 3]
groupBy([{ r: 'admin' }, { r: 'user' }, { r: 'admin' }], i => i.r); // { admin: [...], user: [...] }

const merged = deepMerge({ a: 1 }, { b: 2 }); // { a: 1, b: 2 }

3. Isomorphic safeStorage Wrapper

import { safeStorage } from '@dev_x_mohit/opti-kit';

// Zero-throw wrapper: works in Next.js/React SSR without window errors!
// Supports native object JSON parsing and custom millisecond expiration times:
safeStorage.setItem('user_session', { id: 'usr_99', role: 'admin' }, 60000); // 1 minute expiration
const session = safeStorage.getItem('user_session'); // { id: 'usr_99', role: 'admin' }

4. Async Retry & Debounce

import { delay, retry, debounce } from '@dev_x_mohit/opti-kit';

await delay(500); // sleep 500ms

// Automatically retry failed API calls 3 times with exponential backoff
const data = await retry(async () => fetchApiData(), 3, 500);

// Debounce expensive handlers
const onSearch = debounce((query) => executeSearch(query), 300);
