If you’ve been writing JavaScript for more than 10 minutes, you already know one thing:
you keep rewriting the same tiny utility functions over and over again.
That’s stupidly inefficient.
So I built coderkit, a lightweight, practical utility toolkit meant to kill repetitive code and give you a clean, reliable set of helpers you actually use in day-to-day dev work.
No clutter. No over-engineered “generic utility abstraction patterns.”
Just real functions solving real problems.
⭐ What Exactly Is coderkit?
A compact collection of JS utilities that handle common tasks cleanly and consistently.
It currently includes basic foundational helpers, and the goal is to expand it into:
50+ real-world utilities — string helpers, array manipulation, date processing, financial calculators, object operations, and more.
The focus is on:
- Simplicity
- Readability
- Daily usefulness
- Zero unnecessary bloat
🔧 Feature Categories in coderkit
This section breaks down what the toolkit actually aims to offer.
📘 Math Utilities
Forget rewriting the same formulas all the time. These helpers cover:
- Accurate arithmetic (fix JS floating-point nonsense)
- Range clamping
- Percentage helpers
- Rounding utilities
- Average, sum, min/max helpers
Clean math logic without surprises.
📦 Array Utilities
Probably the most repetitive area in JS development. coderkit includes:
- Unique filtering
- Deep flatten
- Chunking
- Smart sorting
- Grouping
- Safe merging
These are the functions every dev ends up rewriting from scratch in every new project.
🧩 Object Utilities
JS objects get messy fast. These utilities keep them predictable:
- Deep clone (properly)
- Deep merge
- Safe nested property access
- Object diff
- Key/value transformers
- Cleanup helpers (remove empty/null values)
No more hacks or slow lodash clones unless you actually need them.
🔡 String Utilities
Small helpers you constantly need:
- Capitalize, title case
- Trim variations
- Slugify
- Random string/ID generator
- Regex-safe replace helpers
- Case-insensitive comparisons
Perfect for both frontend UI logic and backend formatting.
💰 Financial Utilities
This category matters because financial logic gets tricky quickly:
- Tax calculations
- Discount logic
- EMI calculators
- Profit/loss helpers
- Currency formatting
- Financial rounding (banker’s rounding, etc.)
Useful for dashboards, billing systems, inventory apps, or any business-related UI.
🎯 Purpose — Why coderkit Exists
Most JS projects don’t need a massive library like Lodash, but they still need small helper functions.
Instead of installing 40kb of code to use only one function…
coderkit gives you the exact utilities you need — nothing more, nothing less.
- Tiny package
- Modular imports
- Beginner-friendly
- Works in any JS/TS project
- Clean, readable code
This toolkit is meant to be practical, not academic.
📦 Installation
npm install coderkit
Usage is straightforward:
import { add, subtract, multiply } from "coderkit";
console.log(add(5, 10)); // 15
🧭 Roadmap (Focused & Realistic)
- Add 50+ essential utilities
- Improve documentation
- Full TypeScript support
- Add benchmarks and performance notes
- Release v1.0 with all planned categories
