Paddle.js is a browser JavaScript library for opening the checkout of the payment service Paddle on a web page and retrieving pricing information. You add the script to the page, set a client token with Paddle.Initialize, and then open an overlay or inline checkout with Paddle.Checkout.open. An npm package wrapper is also provided, so it can be used with type support in frameworks such as React.
