This repo is forked from iamdustan/smoothscroll and rewritten with TypeScript.

Installation and use

 # npm
npm install seamless-scroll-polyfill --save

# yarn
yarn add seamless-scroll-polyfill

Use polyfill to patch all methods

 import { polyfill } from "seamless-scroll-polyfill";

polyfill();

Use specific polyfill

 import { elementScrollIntoViewPolyfill } from "seamless-scroll-polyfill";

elementScrollIntoViewPolyfill();

Use methods directly without patching

 import { scrollIntoView } from "seamless-scroll-polyfill";

scrollIntoView(document.querySelector("#target"), { behavior: "smooth", block: "center", inline: "center" });

Import via script

 <!-- please replace the `latest` with specific version -->
<script src="https://cdn.jsdelivr.net/npm/seamless-scroll-polyfill@latest"></script>
<script>
    // patch all methods
    seamless.polyfill();
    // or use specific methods
    seamless.scrollBy(window, { behavior: "smooth", top: 200, left: 0 });

    seamless.scrollIntoView(document.querySelector("#target"), {
        behavior: "smooth",
        block: "center",
        inline: "center",
    });
</script>
