How to Contribute

1. Create a new or modify YAML OpenAPI spec for Label Studio endpoints. For example, ./fern/openapi/resources/comments.yaml:

   paths:
    /api/comments:
      get: ...
      post: ...
   components:
    schemas:
      Comments: ...
    requestBodies:
      api_comments_create: ...

   • paths : contain API path
   • components (optional): components to reuse in responses
   • requestBodies (optional): request bodies specification to reuse in requests’ requestBody
2. Add $ref references in overrides.yaml:

   paths:
    /api/comments/:
      get:
        $ref: "./resources/comments.yaml#/paths/~1api~1comments/get"
        x-fern-sdk-group-name: comments
        x-fern-sdk-method-name: list
        x-fern-audiences:
          - public
      post:
        $ref: "./resources/comments.yaml#/paths/~1api~1comments/post"
        x-fern-sdk-group-name: comments
        x-fern-sdk-method-name: create
        x-fern-audiences:
          - public

   this will define the public methods called client.comments.list() and client.comments.create(). Read more about Fern's OpenAPI extensions
3. Create a PR in label-studio-client-generator using Follow-Merge workflow. For example, push a branch called fb-PRJ-123-update-comments-api
4. Ensure PR is created in label-studio-sdk and Label Studio repo
5. Update added endpoints in Django code.
6. Add integration tests with newly added functions in LS: https://github.com/HumanSignal/label-studio/tree/develop/label_studio/tests/sdk

Create openapi.yaml

swagger2openapi --yaml --outfile ./fern/openapi/openapi.yaml http://localhost:8080/docs/api?format=openapi

Generate docs

fern generate --docs

Generate docs locally

fern docs dev

Add custom docs

Go to fern/openapi/overrides.yaml and modify fields keeping the structure as in fern/openapi/openapi.yaml. For example

paths:
  /api/projects/:
    post:
      summary: List of Projects

-->

paths:
  /api/projects/:
    post:
      summary: A new title to be replaced
    get:
      description: and another update in description `/get` endpoint.

Generate SDK locally

1. Ensure label-studio-sdk is at the same level as this generator directory, for example:

parent/
├── label-studio-client-generator/
└── label-studio-sdk/

2. Ensure you have a local Label Studio instance running in docker container with name label-studio-enterprise-app-1.
3. Run ./localgen.sh to generate SDK locally. The package will be generated in label-studio-client-generator/label_studio_sdk/ directory.
4. Test the generated SDK by running python -c "from label_studio_sdk import LabelStudio".
