serverless

What is serverless?

The serverless npm package is a framework that allows you to build serverless applications using cloud providers like AWS Lambda, Azure Functions, Google Cloud Functions, and more. It abstracts away the infrastructure management tasks, enabling developers to focus on writing application logic.

What are serverless's main functionalities?

Deployment Automation

Automates the deployment of your serverless application to the cloud provider. The 'serverless deploy' command packages your application, uploads it to the cloud provider, and sets up the necessary services like AWS Lambda, API Gateway, etc.

Function Invocation

Allows you to invoke a deployed function directly from the command line. The '-f' flag specifies the function name you want to invoke, in this case, 'hello'.

serverless invoke -f hello

Local Development

Enables local development and testing of serverless applications. The 'serverless offline' plugin simulates AWS Lambda and API Gateway on your local machine to speed up development cycles.

Logs Retrieval

Retrieves logs for a specific function from the cloud provider. The '-f' flag specifies the function name whose logs you want to view, in this case, 'hello'.

serverless logs -f hello

Configuration Management

Allows you to define your serverless application's configuration in a 'serverless.yml' file. This includes the service name, provider details, runtime, functions, events, and other resources.

service: myService
provider:
  name: aws
  runtime: nodejs12.x
functions:
  hello:
    handler: handler.hello
