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).
