@app

@app declares the application namespace

Syntax

• Lower + upper case alphanumeric string
• Maximum of 100 characters
• Dashes and underscores are allowed
• Must begin with a letter

🪧 Changing the project’s app name or region between deployments will create a new CloudFormation stack. The app namespace is used to create a stack name, which is unique to each AWS region.

Example

Create an app with the namespace “foobaz”:

@app
foobaz

{
  "app": "foobaz"
}

---
app: foobaz
