simple-boost – The Lightning Payment Button

🚀 Usage

HTML / Web Component

Include the script and drop the <simple-boost> tag anywhere on your page:

<script type="module" src="https://esm.sh/simple-boost@latest"></script>

<simple-boost 
  address="hello@getalby.com" 
  amount="2100" 
  currency="sats">
  Support our work
</simple-boost>

React

⚠️ Important: Required Packages

The React wrapper depends on the following packages to work:
react, react-dom, and @lit/react
Installing these ensures the component works correctly in your React project.

npm install react react-dom @lit/react

The React wrapper will not work in a non-React project.

import { SimpleBoostButton } from "simple-boost/react";

function Boost() {
  return (
    <SimpleBoostButton
      address="hello@getalby.com"
      amount={2100}
      currency="sats"
    >
      Support our work
    </SimpleBoostButton>
  );
}

export default Boost;
