Async-Attempt

Intuitive way of using async-await

Attempt is a zero dependency library which helps you to use multiple awaits without cluttering your code with unnecessary try/catch.

Installation

npm i async-attempt

Usage

import attempt, { Result } from "async-attempt";

let result: Result<string> = await attempt(readFile('myFile.txt'))

if(!result.ok) {
    console.error(result.error)
    return;
}

console.log(result.data)

Here readFile function returns a promise. Using attempt function one can call the readFile function almost synchronously without the hastle of try/catch. This is specially helpfull if you have to call numerous functions with await.

Default value

With the attempt function you may also pass a default value, which is returned if the promise is rejected.

let result = await attempt(readFile('myFile.txt'), "Some default string.")

or simply

let {data} = await attempt(readFile('myFile.txt'), "Some default string.")

So you are always sure that the promise returns a valid value without the hastle of writing the boiler plate code.
