1. Install

$ npm install -g serverless

2. Create

Just create the following simple boilerplate:

$ touch serverless.yml # more info in the "Configure" section below
$ touch index.js       # your lambda code
$ touch .env           # your AWS api keys
# .env
AWS_ACCESS_KEY_ID=XXX
AWS_SECRET_ACCESS_KEY=XXX

the index.js file should look something like this:

module.exports.createUser = async (e) => {
  return {
    statusCode: 200,
    body: 'Created User'
  }
}

module.exports.getUsers = async (e) => {
  return {
    statusCode: 200,
    body: 'Got Users'
  }
}

module.exports.auth = async (event, context) => {
  return {
    principalId: 'user',
    policyDocument: {
      Version: '2012-10-17',
      Statement: [
        {
          Action: 'execute-api:Invoke',
          Effect: 'Allow',
          Resource: event.methodArn
        }
      ]
    }
  }
}

Keep reading for info on how to set up the serverless.yml file.

3. Configure

You can configure the component to either create a new REST API from scratch, or extend an existing one.

Creating REST APIs

You can create new REST APIs by specifying the endpoints you'd like to create, and optionally passing a name and description for your new REST API. You may also choose between a lambda proxy or http proxy integration by using the function or proxyURI field respectively. The function field will override the proxyURI field.

# serverless.yml

createUser:
  component: "@serverless/aws-lambda"
  inputs:
    code: ./code
    handler: index.createUser
getUsers:
  component: "@serverless/aws-lambda"
  inputs:
    code: ./code
    handler: index.getUsers
auth:
  component: "@serverless/aws-lambda"
  inputs:
    code: ./code
    handler: index.auth

restApi:
  component: "@serverless/aws-api-gateway"
  inputs:
    description: Serverless REST API
    endpoints:
      - path: /users
        method: POST
        function: ${createUser.arn}
        authorizer: ${auth.arn}
      - path: /users
        method: GET
        function: ${getUsers.arn}
        authorizer: ${auth.arn}
      - path: /users
        method: PUT
        proxyURI: https://example.com/users
        authorizer: ${auth.arn}
        apiKeyRequired: false

Extending REST APIs

You can extend existing REST APIs by specifying the REST API ID. This will only create, remove & manage the specified endpoints without removing or disrupting other endpoints.

# serverless.yml

createUser:
  component: "@serverless/aws-lambda"
  inputs:
    code: ./code
    handler: index.createUser
getUsers:
  component: "@serverless/aws-lambda"
  inputs:
    code: ./code
    handler: index.getUsers

restApi:
  component: "@serverless/aws-api-gateway"
  inputs:
    id: qwertyuiop # specify the REST API ID you'd like to extend
    endpoints:
      - path: /users
        method: POST
        function: ${createUser.arn}
      - path: /users
        method: GET
        function: ${getUsers.arn}
