Scroll-To-Hash-Element

npm GitHub License GitHub package.json dev/peer/optional dependency version

No longer requires react-router as dependency!

This component enables hash/anchor links to function within a React application.

It works by listening to the hash property of window.location and scrolling to the matching element if it exists.

This was originally written to solve the issue of hash links no longer working with React Router v6+, and required react-router as a dependency. However, it has been refactored to work with any router (or lack thereof).

Scrolling itself is provided by the native browser method Element.scrollIntoView()

Installation

Install the package with npm or yarn

npm install @cascadia-code/scroll-to-hash-element

Just place this component anywhere in the top level of the application and it will work passively in the background.

import React from "react";
import ScrollToHashElement from "@cascadia-code/scroll-to-hash-element";

import Header from "./Header";
import Content from "./Content";

const App = () => {
  return (
    <div className="grid">
      <ScrollToHashElement />
      <Header />
      <Content />
    </div>
  );
};

export default App;

Usage

Creating Hash Links

With React-Router

You can create React-Router links as you normally would. For example a link to a hash element on the homepage would look like this

<Link to="/#some-div-id">Link Text</Link>

or this

<Link to="#some-div-id">Link Text</Link>

a sub page like this

<Link to="/about#story">Our Story</Link>

Without React-Router

You can create standard anchor tags. For example a link to a hash element on the homepage would look like this

<a href="https://github.com/ncoughlin/scroll-to-hash-element/blob/main/#some-div-id">Link Text</a>

or this

<a href="#some-div-id">Link Text</a>

a sub page like this

<a href="https://github.com/ncoughlin/scroll-to-hash-element/blob/main/about#story">Our Story</a>

Customize Scroll Behavior

You can customize the scroll behavior by passing props to the ScrollToHashElement component.

<ScrollToHashElement behavior="smooth" inline="center" block="center" />
prop default options
behavior "auto" "auto", "instant", "smooth"
inline "nearest" "center", "end", "nearest", "start"
block "start" "center", "end", "nearest", "start"
