Intro to Serverless Framework

Welcome! In this lesson, we'll get acquainted with the Serverless Framework, a powerful command-line interface (CLI) tool.

It helps you build, deploy, and manage serverless applications across different cloud providers, including AWS Lambda.

Why Use Serverless Framework?

The Serverless Framework simplifies serverless development significantly. Here's why it's popular:

Cloud-Agnostic: Works with AWS, Azure, Google Cloud, and more.
Simplified Deployment: Automates the creation of cloud resources needed for your functions.
Consistency: Provides a standardized way to define and manage your serverless applications.
Focus on Code: Lets you concentrate on writing your application logic, not infrastructure setup.

Core Concepts: Services & Functions

Let's understand some key terms:

Service: Your project. It's a collection of related functions, events, and resources. Defined in a serverless.yml file.
Function: A single Lambda function (or similar compute unit in other clouds). It's your actual code.
Event: What triggers your function. Examples include HTTP requests, S3 uploads, or database changes.

Installing the Serverless CLI

First, you'll need Node.js and npm installed on your machine. Then, you can install the Serverless Framework CLI globally using npm:

npm install -g serverless

Creating Your First Service

Once installed, you can create a new serverless service using the serverless create command. You'll specify a template for your desired cloud provider and runtime.

For an AWS Node.js service, you might use:

serverless create --template aws-nodejs --path my-first-service

Understanding serverless.yml

The core of your Serverless Framework project is the serverless.yml file. This YAML file defines your service's configuration, including provider, functions, and events.

Here's a basic structure:

service: my-first-service
frameworkVersion: '3'

provider:
  name: aws
  runtime: nodejs18.x

functions:
  hello:
    handler: handler.hello

Defining a Lambda Function & Event

In serverless.yml, you define your Lambda functions and the events that trigger them. For example, to make our hello function accessible via an HTTP API endpoint:

service: my-first-service
frameworkVersion: '3'

provider:
  name: aws
  runtime: nodejs18.x

functions:
  hello:
    handler: handler.hello
    events:
      - httpApi:
          path: /hello
          method: get

Writing the Handler Code

Now, let's look at the actual Node.js code for our hello function, typically located in handler.js. This code will be executed when the HTTP API event triggers it.

Try running this example:

'use strict';

module.exports.hello = async (event) => {
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'Hello from Serverless Framework!',
        input: event,
      },
      null,
      2
    ),
  };
};

Deploying Your Service

Once your serverless.yml and handler code are ready, deploying your serverless application to AWS is as simple as running a single command:

The framework will package your code, create the necessary AWS resources (Lambda function, API Gateway endpoint, IAM roles), and deploy them.

serverless deploy
