1089

1090
+ In most cases your application or library code should have no issues with
1091
+ ` AsyncLocalStorage ` . But in rare cases you may face situations when the
1092
+ current store is lost in one of asynchronous operations. Then you should
1093
+ consider the following options.
1094
+
1095
+ If your code is callback-based, it is enough to promisify it with
1096
+ [ ` util.promisify() ` ] [ ] , so it starts working with native promises.
1097
+
1098
+ If you need to keep using callback-based API, or your code assumes
1099
+ a custom thenable implementation, you should use [ ` AsyncResource ` ] [ ] class
1100
+ to associate the asynchronous operation with the correct execution context.
