Hi, no extra document, because in most of the cases you integrate jsreport on the server, not on the client.
Do you have a specific case when it makes sense to call jsreport directly from the front end?

Is the jsreport actually properly running? I mean can you reach the jsreport studio through browser?
How is your jsreport hosted? As the windows service, or inside iisnode?
Can you provide the startup logs?

@jan_blaha ,
