How to export all firebase remote config keys and values?

Question

I want to migrate from existing firebase project to a new firebase project Issue is that I have a lot of remote config keys and values in my existing project Now I want to export all remote config keys and values then import to the new firebase project rather than writing everything over again in new project.

Is there any easy way to do it?.

Answer 1

You cannot do it from the Firebase console, but you can write a simple script which uses the Remote Config REST API - https://firebase.google.com/docs/remote-config/use-config-rest

So essentially you can download remote config from one project and then upload that into the new project - programmatically.

You can get the remote config keys and values as follows (Swift 4.2):

let remoteConfig = RemoteConfig.remoteConfig()
let ns = NamespaceGoogleMobilePlatform // Oddly evaluates to: "configns:firebase" including spelling mistake

let remoteKeys = remoteConfig.allKeys(from: .remote, namespace: ns)
let remoteDict = Dictionary(uniqueKeysWithValues: remoteKeys.map { ($0, remoteConfig[$0].stringValue) })

let defaultKeys = remoteConfig.allKeys(from: .default, namespace: ns)
let defaultDict = Dictionary(uniqueKeysWithValues: defaultKeys.map { ($0, remoteConfig[$0].stringValue) })

let staticKeys = remoteConfig.allKeys(from: .static, namespace: ns)
let staticDict = Dictionary(uniqueKeysWithValues: staticKeys.map { ($0, remoteConfig[$0].stringValue) })

In my brief searching, I couldn't get the flattened remoteConfig keys and values (i.e. what gets returned when using the subscript: remoteConfig[key]). I'm guessing you'd just need to overlay the remote values over the default values?
