Ko-fi overlay widget

Jump to usage

A React component for accepting donations though Ko-fi without leaving your website:

Features

• Fully customize donate button style & content
• Accept donations in page context (no redirect)
• Customize donation panel size & placement
• Trigger a function when donation panel is open or closed

Motivation

To set up what Ko-fi calls their "Floating Button Donation Widget," they let you do some basic customization and ask you to copy and paste two <script> tags onto your site:

This has some limitations:

• Only a few choices for button CTA (call-to-action text)
• Limited selection of background colors
• Requires you to load a <script> tag from their CDN, which creates a global variable, and you then need to call a method on that global to render the donate button. Few potential issues with that:
  • Requires an extra network request on every page load
  • Doesn't work well with modern JS bundling + import/export syntax
  • Doesn't work well with a React component-based frontend
  • Doesn't play nice with web frameworks like Next.js. Next.js makes it difficult to inject an arbitrary script like kofiWidgetOverlay.draw(...) – and to only run that code after the external overlay-widget.js script is loaded.

This component is designed to address those limitations.

Install

npm install react-kofi-overlay

(or equivalent on your package manager)

Usage

Props

Prop	Required	Type	Description
(children)	required	ReactNode	Contents of the donation button. Can be plain text or any React nodes that are valid children of a <button> element.
username	required	string	Ko-fi profile to display in the donation panel. Corresponds to the page at ko-fi.com/<username>.
classNames	optional	object	Class names to apply to different parts of the component for styling. See Styling for more info.
styles	optional	object	Inline styles to apply to different parts of the component for styling. See Styling for more info.
onToggle	optional	function	Function to call when the donate panel is opened or closed. It receives one argument: a boolean open value that indicates if the panel was opened or closed.

Styling

The component accepts classNames or styles props to customize the appearance of the donate button and various parts of the donate panel. Both props should be an object with one or more of the keys below.

Note: While you could provide both classNames and styles, it isn't recommended because they will override one another. Pick one based on how you're writing CSS in your codebase.

Name	Description
donateBtn	Donate <button> element.
panel	Wrapper <div> around panel that appears when donate button is clicked. By default, the panel is anchored to the bottom right of the viewport on desktop and full screen on mobile.
closeBtn	<button> to close the donate panel.
closeIcon	(X) icon within the panel close button.
profileLink	Wrapper <div> around the link to your Ko-fi profile. By default, it's anchored to the bottom of the donate panel.
