There are 2 zip files. One for the state of the project at the beginning of the tutorial, and one for the state of the project after implementing the steps shown in the tutorial. If you want to test the “after” code, you will still need to create your own project in the firebase console and paste in the configuration details of your app in the environment.ts file as demonstrated in the tutorial.
Once you have downloaded and unzipped the project code repository, open your terminal or cmd and run $ npm install in order to install the project dependencies.
