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:

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, https://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.
