Wild Workouts

Wild Workouts is an example Go DDD project that we created to show how to build Go applications that are easy to develop, maintain, and fun to work with, especially in the long term!

The idea for this series, is to apply DDD by refactoring. This process is in progress! Please check articles, to know the current progress.

No application is perfect from the beginning. With over a dozen coming articles, we will uncover what issues you can find in the current implementation. We will also show how to fix these issues and achieve clean implementation by refactoring.

Google Cloud Deployment

> cd terraform/
> make

Fill all required parameters:
	project [current: wild-workouts project]:       # <----- put your Wild Workouts Google Cloud project name here (it will be created) 
	user [current: [email protected]]:                # <----- put your Google (Gmail, G-suite etc.) e-mail here
	billing_account [current: My billing account]:  # <----- your billing account name, can be found here
	region [current: europe-west1]: 
	firebase_location [current: europe-west]: 

# it may take a couple of minutes...

The setup is almost done!

Now you need to enable Email/Password provider in the Firebase console.
To do this, visit[your-project]/authentication/providers

You can also downgrade the subscription plan to Spark (it's set to Blaze by default).
The Spark plan is completely free and has all features needed for running this project.

Congratulations! Your project should be available at: https://[your-project]

If it's not, check if the build finished successfully:[your-project]
