To make a React VR app for the web, build its 3D scene with React Three Fiber, then use @react-three/xr to enter and manage an immersive WebXR session. Add a VR entry button, controller and hand input, and runtime support checks; develop with a desktop emulator where available, then test on a compatible headset. Deploy over HTTPS.
This guide is about browser-based WebXR apps—not a native headset app. “React VR” can also refer to the older React 360 project; Meta’s porting guidance says React 360 currently does not support WebXR, so it is not the right starting point for a new WebXR app.
What you need to build a React VR app
React Three Fiber is a React renderer for three.js: you describe a 3D scene with React components, and Fiber renders it through three.js. The @react-three/xr package adds React components and hooks for WebXR, including the VR entry button and input components.
- A React app with compatible React and React Three Fiber major versions. The Fiber documentation pairs Fiber 8 with React 18 and Fiber 9 with React 19.
three,@types/three, and@react-three/fiber, as listed in the Fiber installation documentation, plus@react-three/xrfor XR support.- A WebXR-capable browser and headset for immersive on-device testing. Meta’s React tutorial also offers a desktop emulator path for development.
Meta Horizon OS Developers’ React WebXR tutorial specifies Node.js 20.x or later and npm 10.x or later. Those are the requirements for that tutorial, not a guarantee that every React or WebXR project has identical requirements.

Start with a scene, then add WebXR
First render a simple scene in a Fiber <Canvas>. Put scene objects and lights inside it, then wrap the scene with <XR> and add the XR controls. This small starting point follows the @react-three/xr documented pattern:
import { Canvas } from '@react-three/fiber'
import { VRButton, XR, Controllers, Hands } from '@react-three/xr'
export default function App() {
return (
<>
<VRButton />
<Canvas>
<XR>
<Controllers />
<Hands />
<mesh>
<boxGeometry />
<meshBasicMaterial color="blue" />
</mesh>
</XR>
</Canvas>
</>
)
}The blue box is only a scene sanity check. Replace it with your own components and interaction logic as you build out the experience. The VR button gives the user an entry point to immersive mode; starting a session in response to a user gesture is important for WebXR.
Check device support and choose a play area
Do not infer XR support from a browser’s user-agent string. Meta recommends feature detection with navigator.xr?.isSessionSupported(...). Check the session mode your app needs—such as immersive-vr—and provide a non-immersive fallback or a clear unavailable state if the browser does not support it.

Request or use the appropriate reference space for the experience. Meta’s guidance identifies local-floor and bounded-floor for floor-based, room-scale use cases. The right choice depends on how the app positions the user and whether it needs a bounded play area; do not assume every device provides the same room setup.
Add controller and hand interactions
Include <Controllers /> and <Hands /> inside the XR scene when the experience should support those inputs. Then map input events to actions that make sense in the scene—for example, selecting an object, activating a tool, or firing a projectile—and show the result visually or with sound.
Meta’s Quest guidance describes controller input through targetRaySpace, gripSpace, and an xr-standard Gamepad. Hand tracking exposes 25 joints. @react-three/xr wires these inputs by default, but your app still needs to define what each interaction does. Treat hands and controllers as input options, not assumptions: check the capabilities available in the active session and make essential actions understandable without relying on a single input method.

Load 3D assets and build interaction state
Use glTF or GLB models for imported 3D content. Meta’s React sample demonstrates loading glTF models, extracting sub-objects, and cloning instances—useful techniques when a scene reuses the same asset many times. Keep asset complexity appropriate for real-time rendering on the headset you intend to support; the available sources do not establish a universal model or performance budget.
For an interactive experience, keep shared game state—such as a score or active projectiles—in a state layer accessible to the components that need it. Meta’s sample uses Zustand for cross-component game data, frame-based animation, and proximity-based collision detection without a physics engine. Those are example techniques, not requirements; a physics engine may be more suitable when the simulation needs more involved physical behavior.

Visual changes are not the only feedback available in VR. Meta’s example covers spatial audio and controller haptics, alongside collision detection and animation. Use feedback selectively: a sound or brief haptic response can confirm an action, while clear visual state should still communicate what changed for users whose device lacks a particular capability.

Test without a headset, then verify on-device
A headset is necessary to test the actual immersive experience, but it need not be the first development step. Meta’s React tutorial includes a built-in desktop emulator path, which can help you iterate on scene content and interaction logic. Emulator behavior is not a substitute for checking the browser, tracking, input, and comfort of the target headset.
- Run the app in a desktop browser or the tutorial’s emulator and verify that the scene renders and its basic interactions work.
- Check the support-detection path and the app’s fallback when immersive WebXR is unavailable.
- Open the app in a WebXR-compatible headset browser, activate VR through the on-page button, and test the intended reference space and input methods.
- Check imported models, animation, audio, collision responses, and any haptic feedback on the device. Test optional features only on devices that report support.
Quest-specific WebXR capabilities listed by Meta include passthrough, plane detection, hit testing, anchors, and DOM overlay. Meta also says depth sensing is not available in Quest WebXR. These are device-specific capabilities, not baseline features to build into every WebXR app; use capability checks and keep the core experience functional without optional features.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Deploy the app for headset access
Serve the deployed web app over HTTPS so it can be opened in a headset browser as a secure web experience. Meta’s tutorial repository includes deployment guidance, including GitHub Pages. After deployment, verify the production URL on the target headset rather than relying only on local desktop testing.

How this stack compares with other WebXR options
React Three Fiber with @react-three/xr is the React-focused approach described here. Meta also lists A-Frame, Babylon.js, and three.js as WebXR-capable alternatives. The sources establish their WebXR capability but do not provide a like-for-like comparison of performance, input setup, or asset workflows.
| Approach | What the available guidance establishes | What is not established |
|---|---|---|
React Three Fiber + @react-three/xr |
React-oriented scene rendering with XR components and hooks; the documented starter includes VRButton, controllers, and hands. | Comparative performance or device coverage versus the alternatives. |
| A-Frame, Babylon.js, or three.js | Meta lists each as WebXR-capable. | A detailed comparison of React integration, controller and hand setup, performance, and asset workflow. |
| React 360 | Meta’s porting guide says it currently does not support WebXR. | Suitability for a new immersive WebXR app. |
Meta Horizon OS Developers’ complete React target-shooting sample is a practical next step after the minimal scene: its documented coverage includes controller input, Zustand-based 3D game state, spatial audio, haptic feedback, proximity collision detection, glTF loading, and frame-based animation. The tutorial is described as two hours long, with setup requirements of Node.js 20.x or later and npm 10.x or later.
