Package Exports

react-cursor-position

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-cursor-position) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

react-cursor-position

A React component that decorates its children with mouse cursor coordinates, plotted relative to itself.

Status

Demo

The react-image-magnify project depends on this package for mouse coordinate observation. Please have a look at the react-image-magnify demo to see this package in action.

For touch position tracking, see react-touch-position. It has a similar architecture and interface.

Installation

npm install --save react-cursor-position

Usage

Intended as a primitive for composing features that require notification of mouse cursor position status.

<ReactCursorPosition>
    <ChildComponentOne/>
    <ChildComponentTwo/>
</ReactCursorPosition>

ReactCursorPosition wraps its children in a div, which mouse cursor position is plotted relative to.

Each child component will receive a prop named cursorPosition, which has the following structure.

{
    x: Number,
    y: Number,
    isOutside: Boolean
}
