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

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

you can use safelyTry to do something like this

import safelyTry from 'safely-try';

const { data: result, error } = safelyTry(somethingMightThrowException);
if (error) {
  handleTheError(error);
  return;
}

or you can use safelyTryTuple to do something like this

import { safelyTryTuple as st } from 'safely-try';

const [result, error] = st(somethingMightThrowException);
if (error) {
  handleTheError(error);
  return;
}
