Krayfaus' Typescript Essentials

This package is a collection of utilities I find useful when coding in TypeScript.

Function	Description
String.prototype.format	Equivalent* alternative to String literals.
String.format	Equivalent* alternative to String literals.
String.value	Avoid (string \| undefined) types.
resolve	Resolves a promise (try...catch) and returns data, error.
wait	Sleep worker thread for `n` milliseconds.

* Slightly faster according to a performance test.

👨‍🏫 Usage

`wait()` and `String.format`

import '@krayfaus/essentials/extend/string';
import { wait } from '@krayfaus/essentials';

async function withEssentials() {
    const delay = await wait(5000); // Sleep for 5 seconds.
    console.info('Waited for {0}ms.'.format(delay));
}

async function withoutEssentials() {
    const delay = setTimeout(function () {
        /* do something after the timeout */
    }, 5000); // Sleep for 5 seconds.
    console.info(`Waited for ${delay}ms.`);
}

`resolve()` and `String.value()`

import axios from 'axios';
import { resolve } from '@krayfaus/essentials';

async function withEssentials() {
    const [response, error] = await resolve(axios.get('/user?ID=12345'));
    if (error) { return handleError(error); }
    const data = String.value(response.data);
    console.log(data);
}

async function withoutEssentials() {
    try {
        const response = await axios.get('/user?ID=12345');
        const data = response.data?.toString() || '';
        console.log(data);
    } catch (error) {
        /* error handling */
    }
}
