Create an opionated fun-stack app environment on AWS. With website, auth, and reactive api.
This repository contains reusable terraform modules to build this app.
Example on how to use it:
- Fun Scala Template: example
SDK library to communicate with the infrastructure in your code:
- Fun SDK Scala: sdk-scala
See local development module for mocking the AWS infrastructure locally:
- Fun Local Environment: local-env
- terraform (>= 1.3.0)
Use it in your terraform deployment as a module. Check out: Examples
For the custom domain: Either register the domain in AWS or create a hosted zone in AWS (then set the Nameservers at your registrar to the values you get from the following command):
aws route53 create-hosted-zone --name <my-domain> --caller-reference $(date +%s)
Run:
terraform init
terraform apply
Go to <my-domain> in your browser.
You can have multiple environments, like dev,staging,prod. Just set stage = "<dev|staging|prod>". These environents can be available online at <stage>.env.<my-domain>.
There are some errors that can occur, when switching between different configurations and/or updating the terraform module.
Error:

Solution:
terraform state rm $(terraform state list | grep -F ".module.auth[0].aws_cognito_user_pool_ui_customization.hosted_ui[0]")Error:
