Label Studio

Label Studio is a complex, NX-managed project divided into three main components:

Main App (apps/labelstudio)

This is the primary application that consolidates all frontend framework elements. It's the hub for integrating and managing the different libraries and functionalities of Label Studio.

Library - Label Studio Frontend (libs/editor)

Label Studio Frontend, developed with React and mobx-state-tree, is a robust frontend library tailored for data annotation. It's designed for seamless integration into your applications, providing a rich set of features for data handling and visualization. Customization and extensibility are core aspects, allowing for tailored annotation experiences.

Library - Datamanager (libs/datamanager)

Datamanager is an advanced tool specifically for data exploration within Label Studio. Key features include:

Installation Instructions

1 - Dependencies Installation:

• Execute yarn install --frozen-lockfile to install all necessary dependencies.

2 - Environment Configuration (Optional for HMR):

• If you want to enable Hot Module Replacement (HMR), create an .env file in the root Label Studio directory.
• Add the following configuration:
  • FRONTEND_HMR=true: Enables Hot Module Replacement in Django.

Optional configurations (defaults should work for most setups):

• FRONTEND_HOSTNAME: HMR server address (default: http://localhost:8010).
• DJANGO_HOSTNAME: Django server address (default: http://localhost:8080).

If using Docker Compose with HMR:

• Update the env_file: .env directive in docker-compose.override.yml under the app service.
• Rerun the app or docker compose service from the project root for changes to take effect.

To start the development server with HMR:

• From the web directory: Run yarn dev
• Or from the project root: Run make frontend-dev

Custom Configuration for DataManager:

• If you need to customize the configuration specifically for DataManager, follow these steps:
  • Duplicate the .env.example file located in the DataManager directory and rename the copy to .env.
  • Make your desired changes in this new .env file. The key configurations to consider are:
    • NX_API_GATEWAY: Set this to your API root. For example, http://localhost:8080/api/dm.
    • LS_ACCESS_TOKEN: This is the access token for Label Studio, which can be obtained from your Label Studio account page.
• This process allows you to have a customized configuration for DataManager, separate from the default settings in the .env.local files.

Usage Instructions

Key Development and Build Commands

• Label Studio App:
  • yarn ls:dev: Build the main Label Studio app with Hot Module Reload for development.
  • yarn ls:watch: Build the main Label Studio app continuously for development.

• General
  • yarn build: Build all apps and libraries in the project.
  • yarn ui:serve: Serve the Storybook instance for the shared UI library.
  • yarn test:e2e: Run end-to-end tests for all apps and libraries.
  • yarn test:integration: Run integration tests for all apps and libraries.
  • yarn test:unit: Run unit tests for all apps and libraries.
  • yarn lint: Run biome linter across all files with autofix.
  • yarn lint-scss: Run stylelint linter across all scss files with autofix.

Git Hooks

This project uses python pre-commit hooks to ensure code quality. To install the hooks, run make configure-hooks in the project root directory. This will install the hooks and run them on every pre-push to ensure pull requests will be aligned with linting for both python and javascript/typescript code.

If for any reason you need to format or lint using the same pre-commit hooks directly, you can run make fmt or make fmt-check respectively from the project root directory.
