React runtime for Rive

Overview

This guide documents how to get started using the React runtime library. Rive runtime libraries are open-source. The source is available in its GitHub repository. This library contains a React component, as well as custom hooks to help integrate Rive into your web application (types included). Under the hood, this runtime is a React-friendly wrapper around the @rive-app/canvas runtime, exposing types, and Rive instance functionality.

Quick Start

See our quick start example that shows how to play a Rive animation with React.

Getting Started

Follow the steps below for a quick start on integrating Rive into your React app.

1. Install the dependency

The Rive React runtime allows for two main options based on which backing renderer you need.
  • (Recommended) @rive-app/react-canvas - Wraps the @rive-app/canvas dependency. Unless you specifically need a WebGL backing renderer, we recommend you use this dependency when using Rive in your apps for quick and fast usage.
  • @rive-app/react-canvas-lite - Similar to @rive-app/react-canvas, but smaller. This is recommended if the Rive graphic does not use Rive Text
  • @rive-app/react-webgl - Wraps the @rive-app/webgl dependency. In the future, we may have advanced rendering features that are only supported by using WebGL. At the moment, however, due to the size of the dependency (with Skia), we do not recommend it unless you have specific needs here. We are currently working on improving the performance and size with the Rive Renderer.
npm i --save @rive-app/react-canvas

2a. Render the Rive component

Rive React provides a basic component as its default import for displaying simple animations with a few props you can set such as artboard and layout. Include the code below in your React project to test out an example Rive animation.
import Rive from '@rive-app/react-canvas';
export const Simple = () => (
<Rive
src="https://cdn.rive.app/animations/vehicles.riv"
stateMachines="bumpy"
/>
);
See here for more on the parameters and return values of the <Rive /> component.

2b. Using the useRive hook

In many cases, you may not only need the React component to render your animation but also the rive object instance that controls it as well. The Rive object instance allows you to tap into APIs for:
  • Setting Rive Text values dynamically
  • Subscribing to Rive Events with your own callbacks
  • Controlling animation playback (i.e. pause and play)
  • ... and much more
The useRive hook returns both this rive instance, as well as the React component that mounts the underlying <canvas> element that Rive will draw onto.
import { useRive } from '@rive-app/react-canvas';
export default function Simple() {
const { rive, RiveComponent } = useRive({
src: 'https://cdn.rive.app/animations/vehicles.riv',
stateMachines: "bumpy",
autoplay: false,
});
return (
<RiveComponent
onMouseEnter={() => rive && rive.play()}
onMouseLeave={() => rive && rive.pause()}
/>
);
}
Note: Rive will not instantiate until the <RiveCopmonent /> is rendered out, as the underlying <canvas> element needs to be present in the DOM. Also, keep in mind that the canvas size depends on the container it's placed within. Initially, this is 0x0. Either pass a className to RiveComponent or wrap RiveComponent with an appropriately sized container.
See here for more on the parameters and return values of useRive.
Additionally, explore subsequent runtime pages to learn how to control animation playback, state machines, and more.

Rendering Considerations with useRive

At this time, we highly recommend isolating your usage of useRive to its own wrapper component if you plan on conditionally rendering the <RiveComponent /> returned from the useRive hook. This is due to Rive being instanced when the component is mounted and the rendering context associated with a specific underlying <canvas> element. When React tries to unmount/re-render, you may end up with the animation restarting or not displaying when a new <canvas> is mounted. By isolating useRive to its own wrapper component, Rive will have a chance to properly clean up, and restart the animation with a new canvas. In a parent component, you can then conditionally render the wrapper component based on any state or prop-based logic.
