Block Information

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 useBlockInformation hook in our React application.

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

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


export function BlockInformationViewer(){
    const data = {round: 1}
    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>Round: {query.data.block.rnd}</h2>
            <h2>Network: {query.data.block.gen}</h2>
            <h2>Txns: {query.data.block.txns?.length || 0}</h2>
        </div>
    )
}
