Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Published

A set of utilities for react on client side

Readme

@kopexa/react-utils

A powerful utility toolkit for advanced React development, part of the Kopexa Sight Design System.


Overview

@kopexa/react-utils provides essential utilities for building robust, scalable, and maintainable React applications. It includes advanced context creation and ref management utilities, designed for modern React (v19+) and seamless integration with the Kopexa Sight ecosystem.

Features

  • createContext: Type-safe, ergonomic context creation with strict mode and custom error messages.
  • mergeRefs: Effortlessly merge multiple refs (callback and object) for advanced component composition.
  • TypeScript-first: Fully typed APIs for maximum safety and DX.
  • Zero dependencies: Only peer-depends on React.

Installation

pnpm add @kopexa/react-utils
# or
yarn add @kopexa/react-utils
# or
npm install @kopexa/react-utils

API

createContext<T>(options?: CreateContextOptions<T>): [Provider, useContext, Context]

A strict, ergonomic alternative to React's context API.

import { createContext } from '@kopexa/react-utils';

const [Provider, useMyContext] = createContext<number>({
  name: 'MyContext',
  strict: true,
  hookName: 'useMyContext',
  providerName: 'MyProvider',
});

function MyComponent() {
  const value = useMyContext();
  // ...
}

Options

  • strict (default: true): Throws if context is missing.
  • hookName, providerName, errorMessage, name, defaultValue: Customize error and context behavior.

mergeRefs<T>(...refs: Ref<T>[]): Ref<T>

Merge multiple refs (callback or object) into a single ref for advanced component composition.

import { mergeRefs } from '@kopexa/react-utils';

function MyInput(props, ref) {
  return <input ref={mergeRefs(ref, props.innerRef)} />;
}

Best Practices

  • Use createContext for all new context providers in your app or library for safer, more maintainable code.
  • Use mergeRefs when you need to forward refs to multiple consumers (e.g., HOCs, hooks, portals).

Why Kopexa Sight?

Kopexa Sight is dedicated to building reliable, developer-friendly open source tools. This package is designed for clarity, stability, and best practices, inspired by the Google API Design Guide.
