Or follow the steps below for creating & deploying a simple service and learning some simple Serverless commands.

Create a new service

Create a new service using the Node.js template, specifying a unique name and an optional path for your service.

# Create a new Serverless Service/Project
$ serverless create --template aws-nodejs --path my-service
# Change into the newly created directory
$ cd my-service

Deploy, test and diagnose your service

Deploy the Service

Use this when you have made changes to your Functions, Events or Resources in serverless.yml or you simply want to deploy all changes within your Service at the same time.

serverless deploy -v

Deploy the Function

Use this to quickly upload and overwrite your function code, allowing you to develop faster.

serverless deploy function -f hello

Invoke the Function

Invokes a Function and returns logs.

serverless invoke -f hello -l

Fetch the Function Logs

Open up a separate tab in your console, set your Provider Credentials and stream all logs for a specific Function using this command.

serverless logs -f hello -t

Cleanup

If at any point, you no longer need your service, you can run the following command to remove the Functions, Events and Resources that were created, and ensure that you don't incur any unexpected charges.

serverless remove
