Set up firebase:

• Create a project at the Firebase console.
• Get your account credentials from the Firebase console at settings>service accounts, where you can click on generate new private key and download the credentials as a json file. It will contain keys such as project_id, client_email and client id. Now copy them into your project in the credentials/server.js file.
• Get your authentication credentials from the Firebase console under authentication>users>web setup. It will include keys like apiKey, authDomain and databaseUrl and it goes into your project in credentials/client.js.
• Copy the databaseUrl key you got in the last step into server.js in the corresponding line.
• Back at the Firebase web console, go to authentication>signup method and select Google.

The idea behind the example

The goal is to authenticate users with firebase and store their auth token in sessions. A logged in user will see their messages on page load and then be able to post new messages.
