reactjs - Robust way to handle app errors inside mapStateToProps? -

i'm looking advice on robust , reliable way handle errors within mapstatetoprops, , if it's advisable attempt @ level within react+redux app.

for example, if use react-redux's connect component , mapstatetoprops:

function mapstatetoprops(state, ownprops) {     throw error('some unfortunate error.');     return {         // data     } }

i want catch error , maybe display error component in place of rendering component. not make attempt recover - pick , move on.

at moment i've noticed stalls react completely, , page need reloaded: uncaught typeerror: cannot read property 'gethostnode' of null

i handle exception regular data since connect still expect props pass them component. i'd this:

function mapstatetoprops(state, ownprops) {  try {    // code    return {        // data    }  } catch (e){    return {        error: e    }  } }

and have component props.error , display error message.
