Flat try

An abstraction to handle exceptions without the need of new code blocks, improving readability (IMO)

Works for both sync and async functions

Install

npm i --save flat-try

Usage

Functions:

const Try = require('flat-try')

const [err, result] = Try(() => myDangerousFunc(arg1))

if (err) {
    // handle it
}

// use the result

If you don't worry about the function context you don't need to wrap it with arrow functions, just use apply:

const Try = require('flat-try')

const [err, result] = Try.apply(myDangerousFunc, arg1, arg2, argN)

if (err) {
    // handle it
}

// use the result

Promises/Async:

const Try = require('flat-try')

const [err, result] = await Try.promise(myDangerousFuncThatReturnsAPromise(arg1))

if (err) {
    // handle it
}

// use the result
