Use JSON to configure complex entities

As your app grows in complexity, you need better ways of supplying configuration to your app. For example, if you want to configure a new login system, you might create one Remote Config parameter for each dynamic value you want to control. However, configuring your login system this way is tedious, and very hard to understand and maintain.

A better way to provide configuration for such a login system would be to use JSON and group all of those parameters into one single parameter. This makes editing and maintaining the login parameter much simpler over time.

The Firebase console provides a JSON validator and pretty-printer that you can use when editing Remote Config parameters. When working in the console, click the {} icon to open the editor.
