How to implement redirect (301 code) mock in serverless framework config (for AWS) without lambda

问题

I'd like that the root path of my API redirect (301) to completely another site with docs. So I have a lambda at e.g /function1 path and the / should return code 301 with another location. And I'd like to do it without another lambda.

This is exactly what is described here, but via aws command line tool. I tried this approach - it works perfectly, but I'd like to configure such API gateway mock via serverless framework config.

Fortunately, the series of CLI commands you linked to can be reproduced in CloudFormation, which can then be dropped into the Resources section of your Serverless template.

In this example, a GET to /function1 will invoke a lambda function, while a GET to / will return a 301 to a well-known search engine.

service: sls-301-mock

provider:
  name: aws
  runtime: nodejs12.x
  stage: dev
  region: us-east-1

functions:
  hello:
    handler: handler.hello
    events:
      - http:
          path: function1
          method: get

resources:
  Resources:
    Method:
      Type: AWS::ApiGateway::Method
      Properties:
        HttpMethod: GET
        ResourceId: 
          !GetAtt ApiGatewayRestApi.RootResourceId
        RestApiId: 
          Ref: ApiGatewayRestApi
        AuthorizationType: NONE
        MethodResponses:
          - ResponseModels: {"application/json":"Empty"}
            StatusCode: 301
            ResponseParameters: 
              "method.response.header.Location": true
        Integration:
          Type: MOCK
          RequestTemplates:
            "application/json": "{\n \"statusCode\": 301\n}"         
          IntegrationResponses:
            - StatusCode: 301
              ResponseParameters:
                "method.response.header.Location": "'https://google.com'"

Tested with:

Framework Core: 1.62.0
Plugin: 3.3.0
SDK: 2.3.0
Components Core: 1.1.2
Components CLI: 1.4.0

Notes

ApiGatewayRestApi is, by convention, the logical name of the API Gateway Stage resource created by Serverless on account of the http event.

EDIT

This answer is not as verbose, and uses an http event instead of the Resources section. I haven't tested it, but it may also work for you.

Managed to achieve it with referring one function twice. But see also reply of Mike Patrick - looks more universal

    ...
    events:
      - http:
          path: main/root/to/the/function
          method: get
          cors: true
      - http:
          path: /
          method: get
          integration: mock
          request:
            template:
              application/json: '{"statusCode": 301}'
          response:
            template: redirect
            headers:
              Location: "'my-redirect-url-note-the-quotes-they-are-important'"
            statusCodes:
              301:
                pattern: ''
