Google and Facebook sign-in with cordova / phonegap

Was using this earlier:
https://stackoverflow.com/a/23931392

- now is depricated for google
https://developers.googleblog.com/2016/08/modernizing-oauth-interactions-in-native-apps.html

- and with ios the code does not work, because now when ios opens an in-app-browser instance, it deletes the browser instance where the phonegap app is running. For this to work, both windows contexts should be well alive :P

So,
Most promising option:
https://github.com/EddyVerbruggen/cordova-plugin-googleplus

Follow the steps (lots of prerequisites)

- I had to install 'q' package separately.

npm install q --save

- do take care to match your version of cordova-ios and the cordova-plugin-googleplus
(if this mismatch happens: build errors, runtime errors and dependancy problems will happen)

- do not forget to run prepare

- solving the dependancy problems
  - remove plugin, platform, node_modules

rm -rf mmapp/platforms mmapp/plugins mmapp/node_modules

  - install everything again

phonegap build ios

  - remember to add the info.plist file to the project


Error:
CDVPlugin class GooglePlus (pluginName: GooglePlus) does not exist.
- happens when two versions of the plugin are clashing

Fork of the official plugin, but keeps the SDK version used, updated. Also, actively maintained.

Installation and Examples work out of the box.

Pointers:
- Recent updates to permissions framework
- Graph API Explorer - good tool to test out the graph queries
