# Adding Feature Information

Feature Information is available via the `featureinfo` package. It allows a user to view the attribute data of a `WMS` or raster `GeoTIFF` layer upon clicking on the layer in the map. Please follow the instructions below for how to add Feature Info to your app. 

### Adding Feature Information to your App

{% stepper %}
{% step %}

#### Add the `featureinfo` package to your app

In the packages folder, add the `featureinfo` package. If it is not already present in your app, copy it into the packages folder from [this repository](https://github.com/directedproject-eu/directed-pioneer/tree/main/src/packages). Then, add the package to your application's `packages.json` under `dependencies`. For example: 

```typescript
// your-app/package.json
{
    "name": "my-app",
    "private": true,
    "main": "services.ts",
    "dependencies": {
        "featureinfo": "workspace:^"
    }
}
```

{% endstep %}

{% step %}

#### Install the `featureinfo` package

Run `pnpm install` to install the package.
{% endstep %}

{% step %}

#### Import the package into your app's map

In `MapApp.tsx` (or your main map file), import the package.

```typescript
// your-app/MapApp.tsx
import { FeatureInfo } from "featureinfo";
```

{% endstep %}

{% step %}

#### Add the UI component to your app's map

After the return statement in your `MapApp.tsx`, add the component. This could be, for example, within a `MapAnchor` :

```typescript
// your-app/MapApp.tsx
<MapAnchor position="bottom-left" horizontalGap={15} verticalGap={60}>
    {mapModel && (
        <FeatureInfo
            mapModel={mapModel.map!}
            projection="EPSG:3857"
            layerId={""}
        />
    )}
</MapAnchor>
```

{% endstep %}
{% endstepper %}
