Create new error instances with a code and additional properties.
$ npm install err-code// or$ bower install err-code
The browser file is named index.umd.js which supports CommonJS, AMD and globals (errCode).
I find myself doing this repeatedly:
var err = 'My message';errcode = 'SOMECODE';errdetail = 'Additional information about the error';throw err;
var errcode = ;// fill error with message + codethrow ;// fill error with message + code + propsthrow ;// fill error with message + propsthrow ;
If the passed
Error already has a
.code field, or fields specified in the third argument to
errcode they will be overwritten, unless the fields are read only or otherwise throw during assignment in which case a new object will be created that shares a prototype chain with the original
.message properties will be carried over from the original error and
.code or any passed properties will be set on it.
