If you'd like to use a framework-agnostic package instead, see <https://www.npmjs.com/package/@rerun-io/web-viewer>.
## Install
```sh
npm i @rerun-io/web-viewer-react
```
️ Note:
The package version is equal to the supported Rerun SDK version.
This means that `@rerun-io/web-viewer-react@0.10.0` can only connect to a data source (`.rrd` file, gRPC connection, etc.) that originates from a Rerun SDK with version `0.10.0`!
## Usage
```jsx
import WebViewer from "@rerun-io/web-viewer-react";
export default function App() {
return <WebViewer width="800px" height="600px" rrd="…"/>
}
```
The `rrd` in the snippet above should be a URL pointing to either:
- A hosted `.rrd` file, such as <https://app.rerun.io/version/0.34.0/examples/dna.rrd>
- A gRPC connection to the SDK opened via the [`serve`](https://www.rerun.io/docs/reference/sdk/operating-modes#serve) API
If `rrd` is not set, the Viewer will display the same welcome screen as <https://app.rerun.io>.
This can be disabled by setting the `hide_welcome_screen` prop to `true`.
⚠ It's important to set the viewer's width and height, as without it the viewer may not display correctly.
Setting the values to empty strings is valid, as long as you style the canvas through other means.
️ Note:
This package only targets recent versions of browsers.
If your target browser does not support Wasm imports or top-level await, you may need to install additional plugins for your bundler.
