[codegen] graphql config - multiple extension outputs from a project

[n10000k]

Is your feature request related to a problem? Please describe.
I want to output typescript types to lambda functions as well as my frontend application also.

Describe the solution you'd like
The ability to have many extensions with the same key as amplify within the same project:

projects:
  Workspaces:
    schemaPath: src/graphql/Workspaces/schema.json
    includes:
      - src/graphql/Workspaces/**/*.ts
    excludes:
      - ./amplify/**
    extensions:
      amplify:
        codeGenTarget: typescript
        generatedFileName: src/utils/API.ts
        docsFilePath: src/graphql/Workspaces
        maxDepth: 2
      amplify:
        codeGenTarget: typescript
        generatedFileName: amplify/backend/foobar/API.ts
        docsFilePath: amplify/backend/foobar
        maxDepth: 2
extensions:
  amplify:
    version: 3

Describe alternatives you've considered
Having a folder in the root directory to allow types to be read from there, however it's not easy and requires extra permissions and npm won't let you read outside the main dir it's being ran from. So this will be an issue for lambda functions.

Alternative solution
This would work a better way instead of executing the extension many times;

projects:
  Workspaces:
    schemaPath: src/graphql/Workspaces/schema.json
    includes:
      - src/graphql/Workspaces/**/*.ts
    excludes:
      - ./amplify/**
    extensions:
      amplify:
        codeGenTarget: typescript
        generatedFiles: 
          - src/utils/API.ts
          - amplify/backend/API.ts
        docsFilePaths:
          - src/graphql/Workspaces
          - amplify/backend/Workspaces
        maxDepth: 2
extensions:
  amplify:
    version: 3

An argument made this though could be that you're restricted to one language output at this point. Your frontend is javascript, but your lambda function is python.. it's not going to like the typescript output.

Hi @uncodable Thank you for taking time and requesting this feature. We are working on making the codegen configuration more flexible and customizable. Please look out for an RFC on this.
Meanwhile, if you hadn't figured out already, you could edit the .graphqlconfig.yml file in your project root, edit the path to generatedFiles and run amplify codegen to generate the code at a different place.

Thanks for the update @phani-srikar it's a blocker at the moment on my current project 👍🏻

@uncodable just wanted to let you know that we've publish an RFC to address this and other code generation issues. Would love to have your feedback! aws-amplify/amplify-cli#6898

Any news when it will be ready? Some years already passed.

@hackmajoris as a workaround i found this to be working perfectly fine

(working only if you agree to generate all possible queries and types for some reason when you add/re-add codegen)

projects:
  functionsonsteroids:
    schemaPath: amplify/backend/api/functionsonsteroids/build/schema.graphql
    includes:
      - src/graphql/**/*.graphql
    excludes:
      - ./amplify/**
    extensions:
      amplify:
        codeGenTarget: angular
        generatedFileName: src/app/API.service.ts
        docsFilePath: src/graphql
        region: eu-central-1
        apiId: null
        maxDepth: 2


  lambdaShared:
    schemaPath: amplify/backend/api/functionsonsteroids/build/schema.graphql
    includes:
      - projects/lambda-shared/src/lib/**/*.ts
    excludes:
      - ./amplify/**
    extensions:
      amplify:
        codeGenTarget: typescript
        generatedFileName: projects/lambda-shared/src/lib/generated/app-sync.models.ts
        docsFilePath: projects/lambda-shared/src/lib/generated/
        region: eu-central-1
        apiId: null
        maxDepth: 2

extensions:
  amplify:
    version: 3

Thank you. I have implemented the exact same approach and can confirm that it works fine.
PS: I do use Nx to manage the monorepo, and https://nx.dev/more-concepts/grouping-libraries comes in rescue when dealing with sharing libraries.

What is the easiest way to get codeGenTarget: typescript #and graphql, to output all other things equal?
