Introducing `coderkit` — A Practical Utility Toolkit for Everyday JavaScript Work

[Sascha]

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

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.


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.


npm install coderkit




Usage is straightforward:


import { add, subtract, multiply } from "coderkit";

console.log(add(5, 10)); // 15

• Add 50+ essential utilities
• Improve documentation
• Full TypeScript support
• Add benchmarks and performance notes
• Release v1.0 with all planned categories

Contributions, suggestions, and criticism are always welcome.
If something sucks, say it. That’s how the tool improves.
