Use the configuration files in the
/js/config folder to customize your own map layers, task urls and widgets. The base configuration file is viewer.js and the majority of your work will be here.
Multiple cmv apps may be created by using several different config files, the default is
viewer.js. This offers flexibility if you want to deploy more than one CMV on your site by using a url to call different configs within different
viewer.js files. For example
http://YourServerName/viewer/?config=viewer2 to load a separate config file in config folder or to a completely different folder
Sometimes the configuration object for a widget can be quite involved and length. In those cases, it often makes it easier to separate that widget's configuration into a separate file. Configurations for the Basemaps and Identify widgets are frequently maintained this way.
