Request validation using serverless framework

Question

I am using serverless framework for the backend. How can I implement request validation? (do not want to write validation inside lambda functions).

Answer 1

As Ivan indicated, there is no need for external plugins as this is supported by the Serverless framework. However, I think the way to configure this has changed.

functions:
  create:
    handler: posts.create
    events:
      - http:
          path: posts/create
          method: post
          request:
            schema:
              application/json: ${file(create_request.json)}

This example was taken from: https://www.serverless.com/framework/docs/providers/aws/events/apigateway/#request-schema-validators
