Overview

The svelte-popperjs is a library that provides functionality for integrating Popper (a popular positioning engine) into Svelte applications without the need for wrapper components or component bindings. Unlike other Popper libraries for Svelte, svelte-popperjs takes advantage of Svelte actions to simplify the process and minimize the number of DOM references in the script tag. It can be easily installed as a dev dependency and works well with popular Svelte bundlers like Rollup, Vite, and SvelteKit.
