The following guide describes how to implement smooth scrolling in Gatsby using the smooth-scroll package.

Instructions

1. add the package to your project:

npm install --save smooth-scroll

2. in your layout.js component, import the smooth-scroll package after the import statements but just before the component is rendered:

// layout.js
if (typeof window !== "undefined") {
  require("smooth-scroll")('a[href*="#"]');
}

3. add the id property to the element on the page you want to navigate to:

<InfoSection id="info" />

4. use Gatsby Link to navigate to the desired section of the page:

<Link to="#info">More Info</Link>

The approach described above works if you are trying to link to elements on the same page. However, if you want to implement smooth scrolling for every page, you need to use the Location component from Reach Router in order to access the current location via a render prop.
