Modern, lightweight utility toolkit for JavaScript and TypeScript — including object, array, string, date, and validation helpers.

Features

• 🧠 Object utilities: pick(), omit(), hasField()
• 🔢 Array utilities: unique(), flatten()
• 🔡 String utilities: capitalize(), kebabCase()
• 📅 Date utilities: isToday(), formatDate()
• ✔️ Validation utilities: isEmail(), isEmpty()

Installation

npm install microkitjs
# or
yarn add microkitjs

Usage

Import individual utilities or the whole package:

import { pick, unique, capitalize, isToday, isEmail } from 'microkitjs';

🧠 Object Utilities

const user = { name: 'Alice', age: 30, email: '[email protected]', active: true };

pick(user, ['name', 'email']);
// => { name: 'Alice', email: '[email protected]' }

omit(user, ['age', 'active']);
// => { name: 'Alice', email: '[email protected]' }

hasField(user, 'email');
// => true

hasField(user, 'password');
// => false

🔢 Array Utilities

unique([1, 2, 2, 3, 4, 4]);
// => [1, 2, 3, 4]

flatten([1, [2, 3], [4, [5]]]);
// => [1, 2, 3, 4, [5]] // Note: only one level flattened

🔡 String Utilities

capitalize('hello world');
// => 'Hello world'

kebabCase('Hello World Example');
// => 'hello-world-example'

📅 Date Utilities

isToday(new Date());
// => true (if run on the same day)

formatDate(new Date(), 'YYYY-MM-DD');
// => '2025-06-15' (example output)

✔️ Validation Utilities

isEmail('[email protected]');
// => true

isEmail('invalid-email');
// => false

isEmpty('');
// => true

isEmpty('not empty');
// => false
