Label Studio is an open-source, configurable data annotation tool. ✌️

Frontend, as its name suggests, is the frontend library developed using React and mobx-state-tree, distributed as an NPM package. You can include it in your applications and provide data annotation support to your users. It can be granularly customized and extended.

    },

    task: {
      annotations: [],

      }
    },

    onLabelStudioLoad: function(LS) {
      var c = LS.annotationStore.addAnnotation({
        userGenerate: true
      });
      LS.annotationStore.selectAnnotation(c.id);
    }
  });
</script>

Development

1. Clone the repository

   git clone git@github.com:heartexlabs/label-studio-frontend.git
   # or: git clone https://github.com/heartexlabs/label-studio-frontend.git
   cd label-studio-frontend

2. Install required dependencies

   npm install

3. Start the development server

   npm run start

4. Check different ways to initiate the development server config & task data in src/env/development.js, changing the data variable is a good place to start.

5. After you make changes and ready to use it in production, you need to create a production build

   npm run build-bundle

   Now you have one .js file and one .css file in the build/static/ directory
