feature.redux

This API returns the state for the Scratch website. It only works on Scratch 3.0 pages, where React is used. It returns null on Scratch 2.0 pages. Here's an example:

export default async function ({ feature, console }) {
    // Get the state.
    let state = feature.redux.getState()  
    // It returned important information about the current page, including the logged in user.
}

Similar information can be found on Scratch 2.0 pages using the Scratch variable.
