Custom visuals: change port from 8080

[ChrisWilliams]

I've installed the PBIVIZ custom visualization tools by following the tutorial at https://powerbi.microsoft.com/en-us/documentation/powerbi-custom-visuals-getting-started-with-develo....

However, I have an app on my dev machine that already uses port 8080.  Can this port be changed to some other option, and how would I do that?

If not, may I suggest that you choose another, non-common port for the dev environment?  8080 is fairly popular already so there are bound to be conflicts.

Technically the port can be changed in the file

C:\Users\userName\AppData\Roaming\npm\node_modules\powerbi-visuals-tools\config.json

However the communication between Power BI Service and the visual server seems broken when using a port other than 8080.

So, to avoid the port comflict, develop custom visual on a dedicated dev machine or change the port for the process that is occupying port 8080.
