Any web server can serve up the files. Simply copy the contents html folder to the root folder of a web server of your choice.
A basic Docker Compose file is included under the Docker folder. Testing with Docker is still experimental as we develop more deployment methods to run 4Dpubs.
Single-source is one advantage of 4Dpubs. Because the source is DITA, you can publish that source in any other format that DITA supports. The 4D content displays dynamically in the app, and you can generate static publications for viewing outside of the app. Turbonomic uses 4Dpubs to dynamically deliver help and API documentation. To see this in action, install the Turbonomic product. You also can see static versions of this documentation:
Two examples of 4Dpubs in action:
