capability to host an html / web application in ArcGIS online

[Felix10546]

Hi all,

I am new to ArcGIS API for JavaScript. I want to do something like Dashboard and show some data analysis result from a hosted feature layer. However, I want to add some custom features using other js libraries like what can be call from node.js  . I searched some posts that Dashboard only allow custom widgets (ArcGIS Enterprise) and do not allow editing it like html+javascript. 

If I have written a Client side application in node.js calling Arcgis api for Javascript and other library.

Question: How can I host that application on ArcGIS online so that everyone can access it by uploading my project folder?

P.S. I see there is New item -> Application in ArcGIS online but seem to be referencing an application already hosted online in some url.

Hi @Felix10546, I don't think you can host such an application in ArcGIS Online. Custom apps like what you're describing should be self-hosted by developer/client on their own server or another trusted server.

For a list of what can be hosted and created in ArcGIS Online, please refer to this doc:
