Like the Selenium browser node command-line options, there is also a -nodeConfig option to load a JSON configuration file with all the common AppiumDriver desired capabilities for the nodes.

<span>Here is a sample Selenium node JSON configuration file for iPhone devices:

// iphone_config.json

{
   "capabilities":[
      {
         "platform":"MAC",
         "platformVersion":"10.0",
         "browserName":"iphone",
         "applicationName":"MAC-IPHONE",
         "maxInstances":1,
         "launchTimeout":"300000",
         "newCommandTimeout":"1800"
      }
   ],
   "configuration":{
      "_comment":"Configuration for Selenium Node MAC/IPHONE",
      "proxy":"org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
      "maxSessions":1,
      "cleanUpCycle":5000,
      "timeout":1800,
      "url":"http://127.0.0.1:4723/wd/hub",
      "port":4723,
