safely-try

safelyTry() is a type-safe elegant try-catch replacement for JavaScript / TypeScript inspired by Go error handling.

Installation

npm i --save safely-try

Usage

Instead of using ugly native try-catch like this

letresult;try{result=somethingMightThrowException();}catch(e){handleTheError(e);}

you can use safelyTry to do something like this

importsafelyTryfrom'safely-try';const{data: result, error }=safelyTry(somethingMightThrowException);if(error){handleTheError(error);return;}

or you can use safelyTryTuple to do something like this

import{safelyTryTupleasst}from'safely-try';const[result,error]=st(somethingMightThrowException);if(error){handleTheError(error);return;}
