OpenFin

Configuring Your Application

Suggest Edits

The OpenFin Runtime requires each application to provide a JSON formatted configuration file. This configuration file defines the visual properties of the app, its dependencies, and other deployment settings. The developer is in control of the app development process and how this file is hosted and configured. Both the openfin-cli and OpenFin RVM will use a configuration file to launch applications as well as make use of other configuration data.
