react-scrollspy-nav

react-scrollspy-nav is a React component that provides smooth scrolling navigation to a web page. It also accounts for the factor that a React app may use different React router and therefore has different url patterns (for example the hash pathname in HashRouter).

See the Demo.

Installation

npm i react-scrollspy-nav --save

Usage

import React, { Component } from "react";
import ScrollspyNav from "react-scrollspy-nav";

class App extends Component {
    render() {
        return (
            <div>
                <ScrollspyNav
                    scrollTargetIds={["section_1", "section_2", "section_3"]}
                    offset={100}
                    activeNavClass="is-active"
                    scrollDuration="1000"
                    headerBackground="true"
                >
                    <ul>
                        <li><a href="/">Home</a></li>
                        <li><a href="#section_1">Section 1</a></li>
                        <li><a href="#section_2">Section 2</a></li>
                        <li><a href="#section_3">Section 3</a></li>
                    </ul>
                </ScrollspyNav>
                
                <div>
                    <div style={{"height": "400px"}}><span>Welcome!</span></div>
                    <div id="section_1" style={{"height": "500px"}}><span>Section 1</span></div>
                    <div id="section_2" style={{"height": "500px"}}><span>Section 2</span></div>
                    <div id="section_3" style={{"height": "500px"}}><span>Section 3</span></div>
                </div>
            </div>
        );
    }
}

export default App;

Note:

• The above code provides the skeleton for it to work. You need to style the nav and the target sections yourself to have better visual effect.
• style={{"height": "500px"}} on the section div here is only an example to put more height for each section div to make the page scrollable. Adjust it according to your needs.
