Srotas 🔁

Srotas (स्रोतस्) is a lightweight React-friendly utility library offering a set of reusable event handler functions. It helps developers avoid boilerplate code by offering common event handling patterns — debouncing, throttling, blocking key presses, preventing right clicks, and more.

The name Srotas — derived from Sanskrit — means “stream” or “flow”, a poetic nod to the flow of events this library elegantly manages.

Features 🌊

• 🎯 Focused API: Tiny, purposeful, and highly reusable event utilities.
• 💡 Typed Handlers: Built with full TypeScript support and IDE autocompletion.
• ⚛️ React-Ready: Designed for seamless integration in React apps.
• ⚡ Zero Dependencies: Tree-shakable and dependency-free.
• 🧪 Dev-First: Built with Vite, TypeScript, and tested for production use.

Installation 📦

npm install srotas
# or
yarn add srotas
# or
pnpm add srotas

Prerequisites

Ensure you have the following installed:

• Node.js: v22 or later.
• React: v19 or later.

Usage ⚙️

import {
  preventDefaultOnly,
  stopPropagationOnly,
  preventAndStopEvent,
  debounceEvent,
  throttleEvent,
} from "srotas";

<button onClick={preventAndStopEvent}>Click</button>

You can also use more advanced handlers like:

<input
  onKeyDown={(e) => blockKeyPress(e, ["Enter", "Escape"])}
  onChange={debounceEvent((e) => handleInputChange(e), 300)}
/>

Exports 📤

General Handlers

preventDefaultOnly(e)
stopPropagationOnly(e)
preventAndStopEvent(e)

Debug Handlers

logEventDetails(e)

Context-Specific Handlers

preventRightClick(e)
focusElement("#input-id")
preventDrag(e)
blockKeyPress(e, ["Enter", "Escape"])

Utility Handlers

debounceEvent(handlerFn, delay)
throttleEvent(handlerFn, limit)

All handlers are strongly typed and compatible with React's synthetic events.
