Serverless plugin to set specific validator request on method

Installation

Requirements

This require you to have documentation plugin installed

In serverless.yml create custom resource for request validators

    xMyRequestValidator:  
      Type: "AWS::ApiGateway::RequestValidator"
      Properties:
        Name: 'my-req-validator'
        RestApiId: 
          Ref: ApiGatewayRestApi
        ValidateRequestBody: true
        ValidateRequestParameters: false  

For every function you wish to use the validator set property reqValidatorName: 'xMyRequestValidator' to match resource you described

  debug:
    handler: apis/admin/debug/debug.debug
    timeout: 10
    events:
      - http:
          path: admin/debug
          method: get
          cors: true
          private: true 
          reqValidatorName: 'xMyRequestValidator'

Use Validator specified in different Stack

The serverless framework allows us to share resources among several stacks. Therefore a CloudFormation Output has to be specified in one stack. This Output can be imported in another stack to make use of it. For more information see here.

Specify a request validator in a different stack:

plugins:
  - serverless-reqvalidator-plugin
service: my-service-a
functions:
  hello:
    handler: handler.myHandler
    events:
      - http:
          path: hello
          reqValidatorName: 'myReqValidator'

resources:
  Resource:
    xMyRequestValidator:
      Type: "AWS::ApiGateway::RequestValidator"
      Properties:
        Name: 'my-req-validator'
        RestApiId: 
          Ref: ApiGatewayRestApi
        ValidateRequestBody: true
        ValidateRequestParameters: false
  Outputs:
    xMyRequestValidator:
      Value:
        Ref: my-req-validator
      Export:
        Name: myReqValidator


Make use of the exported request validator in stack b:

plugins:
  - serverless-reqvalidator-plugin
service: my-service-b
functions:
  hello:
    handler: handler.myHandler
    events:
      - http:
          path: hello
          reqValidatorName:
            Fn::ImportValue: 'myReqValidator'
