In this tutorial we are going to explain how to add Log in, Log out, and Sign up functionality to your ionic app using the Firebase services.

You can find the Ionic official installation documentation here.

1. Make sure you have an up-to-date version of Node.js installed on your system. If you don't have Node.js installed, you can install it from here.
2. Open a terminal (Mac) or a command interpreter (cmd, Windows), and install Cordova and Ionic:
   • npm install -g cordova
   • npm install -g ionic
   • On a Mac, you may have to use sudo depending on your system configuration: sudo npm install -g cordova ionic
3. If you already have Cordova and Ionic installed on your computer, make sure you update to the latest version:
   • npm update -g cordova
   • npm update -g ionic
   • Or sudo npm update -g cordova ionic

First we need to link this new Ionic project with our reference repo on github. Clone this repo so we can start working on the app:

• git clone https://github.com/ionicthemes/firebase-authentication-for-your-ionic-app.git
• cd firebase-authentication-for-your-ionic-app

After this, we need to set up some stuff before starting working on the Ionic project. To do so, run these commands:

• npm install
• bower install

Finally, to see the current state of the project, run:

• ionic serve
