How To: Set a proxy in the Web AppBuilder (Developer Edition)


The Developer edition of Web AppBuilder supports the option to set an outbound proxy. This may be useful if it is required to use a proxy to communicate with external URLs such as arcgis.com from the computer running Web AppBuilder.


The documentation related to this article covers the option of adding a proxy and port setting when running Web AppBuilder from the command line. Another option if using the Windows version of node.js, is to edit the startup.bat file that comes with the web app builder.

  • In a text editor, open the startup.bat file. On line number 29 of the bat file there should be the following text.
  • Specify -proxy:port on this line after the start up parameters.
