**Currently there are some problem with React V18**

## Install and Import

Install pannellum-react component

```bash
npm install pannellum-react --save
```

or

```
yarn add pannellum-react
```

Import pannellum-react in your react component file by

```js
import { Pannellum, PannellumVideo } from "pannellum-react";
```

_Note: By using import Pannellum from "pannellum-react/es/elements/Pannellum" the video.js component will be skipped, which decreases the production build by more than 500kb._

> **Note:** Currently only `equirectangular` type is supported! planning to do also `multires`

> **Note:** `Tours` component currently is not supported but is WIP.
> **Note:** For having video tours, there is the custum hotspot which can implement the video scene changing using `handleClick`. In fact in can be the tour for videos and photos.
> **Note:** You can also create your tour with custom hotspot, by changing the image dynamically.
> **Note:** If you manage the props by state, you can update the component smoothly (example: updating yaw, pitch or hfov won't re-render the image and it will dynamically update)

## API

pannellum-react has most of the official pannellum properties (not all of them). It just needed to be passed as props of the `pannellum` component like example above.on

Additionally, by Getting refrence of the component, you can get the pannellum **Viewer** calling `getViewer()` which gives all the available functions of the viewer such as `getPitch`, `setPitch` , `getYaw` and etc. find [here](https://pannellum.org/documentation/api/#viewer)

Moreover, you can force render the component using `forceRender()` in case if you change a prop and didn't change constantly.(example would be hotspot: if you want to update hotspot dynamically, better to call forceRender after updating the hotspots)

> example `this.PanImage.current.getViewer().getPitch()`, PanImage is ref of the component.

> This is working also for the video component
