Usage

tryCatchFin

The tryCatchFin function provides a way to execute asynchronous operations and neatly handle success and failure cases.

Example:

Basic

import * as tcUtils from 'https://raw.githubusercontent.com/sdoerger/tryCatchFin-A-OneLiner/main/mod.ts';

const [result, error] = await tcUtils.tryCatchFin(() => 5 + 5);
tcUtils.assertError(error, 'An issue occurred');

console.log(result);

Async

import * as tcUtils from 'https://raw.githubusercontent.com/sdoerger/tryCatchFinFin-A-OneLiner/main/mod.ts';

async function fetchAnimals() {
    const response = await fetch(
        "https://api.publicapis.org/entries?category=Animals",
        {
            method: "GET",
        }
    );

    return await response.json();
};

const [result, error] = await tcUtils.tryCatchFin(fetchAnimals);
tcUtils.assertError(error, 'An issue occurred');

console.log(result);

assertError

The assertError function logs an error message along with the error if it exists.

Example:

import { assertError } from './helpers.ts';

assertError(new Error("Some error"), "An error occurred");

Running Tests
