I created an application using Appery.io, appery offers publishing on their own hosting but, I need to publish the application on our internal windows IIS server.
Unfortunately, after searching through resources like StackOverflow and other forums, I couldn’t find a clear solution or guidance on how to achieve this.
>Solution :
You need download the app as a mobile web app, click EXPORT > HTML/JS/CSS:

Download the project and unzip it.
The folder should contain package.json.
From inside this catalog, start npm install (you need to have node.js and npm installed): all the dependencies will need to be installed from package.json.
Then run ionic serve which will start the project preview.
ionic build –prod will create the project build that can be then uploaded to whenever you need it.
