sharer.js
Create your own social share buttons. No jquery. Just vanilla JS
...The library supports more than 20 social networks, messaging services, blogging platforms, and bookmarking tools. It can open sharing popups, behave as a regular link, or launch links in a new browser tab. Sharer.js is available through npm, downloadable minified files, and public CDNs. Its manual initialization API also supports buttons added dynamically after the page has loaded.
