Ledger Supply

Let’s look at the preview on the bottom right, we’ll notice that it is not displaying anything. This is because we haven’t yet implemented the useSupply hook in our React application.

To address this, we’ll call the useSupply hook to handle the fetch call in the editor on the top right.

import {useSupply} from '@awesome-algorand/react-query'


export function SupplyViewer(){
    const query = {isLoading: true, isError: false, error: undefined, data: undefined}


    if(query.isLoading) return <div>Loading...</div>
    if(query.isError) return <div>Error: {query.error.message}</div>


    return (
        <div>
            <h2>Online: {query.data["online-money"]}</h2>
            <h2>Total: {query.data["total-money"]}</h2>
        </div>
    )
}
