Clone the repository and install all dependencies:
git clone firstname.lastname@example.org:heartexlabs/label-studio.git cd label-studio npm install
Now you can make any changes to the code or add your custom tags.
npm run start
And open your browser at http://localhost:3000
A good introduction point is to study
src/env/development.js. That file defines a labeling config for the studio as well as creates the environment.
To change the configuration of the project you need to assign the value to the variable
const data = Sentiment;
npm run build-bundle
Generates the compiled version of label studio. This compiled version needs to be included in your app.
