1. Install

$ npm install -g serverless

2. Create

$ mkdir my-function && cd my-function

the directory should look something like this:

|- code
  |- handler.js
  |- package.json # optional
|- serverless.yml
|- .env           # your AWS api keys

# .env
AWS_ACCESS_KEY_ID=XXX
AWS_SECRET_ACCESS_KEY=XXX

// handler.js
module.exports.hello = async (event, context, cb) => {
  return { hello: 'world' }
}

3. Configure

# serverless.yml

myFunction:
  component: "@serverless/aws-lambda"
  inputs:
    name: my-function
    description: My Serverless Function
    memory: 128
    timeout: 20
    code: ./code
    handler: handler.hello
    runtime: nodejs8.10
    env:
      TABLE_NAME: my-table
    region: us-east-1

    # if you'd like to include any shims
    shims:
      - ../shims/shim.js 

    # specifying an existing deployment bucket would optimise deployment speed
    # by using accelerated multipart uploads and dependency management with layers
    bucket: my-deployment-bucket

4. Deploy

$ serverless
