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.

this follow question undefined reference rsa_generate_key in openssl? have openssl program generate rsa key, follows : #include <stdio.h> #include <openssl/rsa.h> #include <openssl/pem.h> int main(int argc, char* argv[]) { rsa *r = null; int ret; r = rsa_new(); bignum *bne = null; ret = rsa_generate_key_ex(r, 2048, bne, null); return 0; } when compile gcc -i../include rsatest.c -lcrypto -l. i undefined reference errors functions in libraries gdi32 , zlib. so correct this, have add -lz , -lgdi32, as gcc -i../include/ rsatest.c -lcrypto -lz -lgdi32 -l. my question is, aren't static libcrypto , libssl self sufficient? in why having add libraries make work? there option should have added while compiling library prevent this? i'm using 64 bit windows mingw compiler. made openssl library of msys , make.
