{{- else if contains "NodePort" .Values.service.type }}
  export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ include "beszel.fullname" . }}-web)
  export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
  echo http://$NODE_IP:$NODE_PORT
{{- end }}
```

{{- else if contains "LoadBalancer" .Values.service.type }}
     NOTE: It may take a few minutes for the LoadBalancer IP to be available.
           You can watch its status by running 'kubectl get --namespace {{ .Release.Namespace }} svc -w {{ include "beszel.fullname" . }}'
  export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ include "beszel.fullname" . }} --template "{{"{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"}})
  echo http://$SERVICE_IP:{{ .Values.service.port }}
{{- end }}

### Implement Dark Mode Theming

Source: https://github.com/henrygd/beszel/blob/main/internal/site/index.html

This script attempts to load a UI theme from local storage. If no theme is set or it's not 'light', it checks the user's preferred color scheme. It then applies the 'dark' or 'light' class to the document element accordingly. This is useful for creating a persistent dark mode for your website.

```javascript
(function() { try { var theme = localStorage.getItem('ui-theme'); var isDark = theme === 'dark' || (theme !== 'light' && window.matchMedia('(prefers-color-scheme: dark)').matches); document.documentElement.classList.add(isDark ? 'dark' : 'light'); } catch (e) {} })();
```

```bash
{{- else if contains "ClusterIP" .Values.service.type }}
  export POD_NAME=$(kubectl get pods --namespace {{ .Release.Namespace }} -l "app.kubernetes.io/name={{ include "beszel.name" . }},app.kubernetes.io/instance={{ .Release.Name }}" -o jsonpath="{.items[0].metadata.name}")
  export CONTAINER_PORT=$(kubectl get pod --namespace {{ .Release.Namespace }} $POD_NAME -o jsonpath="{.spec.containers[0].ports[0].containerPort}")
  echo "Visit http://127.0.0.1:8090 to use your application"
  kubectl --namespace {{ .Release.Namespace }} port-forward $POD_NAME 8090:$CONTAINER_PORT
{{- end }}
```
