Initialize project
AWS SAM provides you with a command line tool, the AWS SAM CLI, that makes it easy for you to create and manage serverless applications. It particularly makes easy the scaffolding of a new project, as it creates the initial skeleton of a hello world application, so you can use it as a baseline and continue building your project from there.
Run the following command to scaffold a new project:
sam init
It will prompt for project configuration parameters:
Type 1 to select AWS Quick Start Templates
Type 1 to select Zip as the package type
Choose nodejs12.x for runtime
Leave default sam-app for project name
Type 1 to select the Hello World Example
This command supports cookiecutter templates, so you could write your own custom scaffolding templates and specify them using the location flag, For example: sam init –location git+ssh://git@github.com/aws-samples/cookiecutter-aws-sam-python.git.
Project should now be initialized
You should see a new folder sam-app created with a basic Hello World scaffolding.
If you are interested in learning more about initializing SAM projects, you can find the full reference for the sam init command in the SAM CLI reference.
