Hello guys,
I'm trying to implement a web-based terminal in my node-RED-dashboard with the template node. For this I am using xterm and now I want to connect it to wetty. But always I'm connecting it to the socket, the following error-message is visible in the console-tab:
> Access to XMLHttpRequest at '[http://10.207.48.36:3000/socket.io/?EIO=4&transport=polling&t=OCXBIJl](http://10.207.48.36:3000/socket.io/?EIO=4&transport=polling&t=OCXBIJl)' from origin '[http://10.207.48.36:1880](http://10.207.48.36:1880)' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
I've already read, that I have to configure the **Access-Control-Allow-Origin** with _Express and Cors_ but I cant figure out how to add the library to the dashboard-template-node.
Here you can see the node:
Thanks in advance
Justin
