react-svgpathplayer

Description/Features

This player component loads an SVG image as it's child element using Snap.svg. It has two modes of operation: play/pause animation of a path element and/or forward/backward display of path elements contained in a parent element ("stepped" path or "stepping").

An SVG marker can also be specified to follow the leading end of the the path during animation and to be positioned at the end of stepped paths.

The player is configured by supplying CSS selector strings for the animated path, parent element of stepped segments, and marker. These strings are supplied to SnapSVG's select method and are applied only to the SVG element in the DOM. CSS class selectors are recommended if multiple players will be used on a single page; if ids are used in SVG images they must be globally unique to the page.

The presence/absence of path and segments properties enables/disables their respective control buttons and display sections.

The player's controls can be hidden and the path can be animated once or looped repeatedly. See the demo for configuration examples.

Usage

As a Component Within a React Application

See the demo for example usage of this component and the composition of the SVG images.

Install the component:

npm install react-svgpathplayer

Unfortunately, Snap.svg doesn't integrate well with the npm infrastructure; it is easiest to just includes it in the HTML or take a look at the demoConfig in the webpack.config.babel.js file.

Include the component in the application, provide it's props, and render it:

import SVGPathPlayer from 'react-svgpathplayer';
require('./images/pathsegments.svg');


export default class Demo extends React.Component {
    render() {
        let props = {svg:'./images/pathsegments.svg',
                     path:'.dog-path-0',
                     segments:'.dog-path-segments-0',
                     marker:'.dog',
                     units:'yd',
                     scale:1/36.0,
                     loading:true,
                     time:10236};
         return (<SVGPathPlayer {...props}/>);
    }
}
