doublet

Handle any Javascript and Typescript function as an error and response tuple. This prevents declaring variables outside of a try/catch block for a cleaner flow.


Installation

``shell
npm i doublet
`

Usage

$3

`ts
import axios from 'axios';
import doublet from 'doublet';
import HttpException from 'your-favorite-error-handler';

async function fetchUser(id: string): User {
let user;

try {
user = await axios(/users/${id});
} catch (error) {
throw new HttpException(Could not fetch user ID "${id}", Error; ${error.message}, error.status);
}

// Do something with user
}

`
