fck-trycatch

Description

Tiny module that exports two functions: attempt and attemptSync. These functions accept a function as first argument and call it wrapped in a try/catch block, returning an error (if any, else null) and whatever was returned by the provided function (if anything, else null).

Usage

attempt/attemptSync accept the following parameters:

• func: the function to be wrapped in try/catch.
• thisArg (optional): if func is a method this argument should be used to bind it to the proper context.
• ...args (optional, depending on func): the arguments to be passed to the function call.

Example

import { attempt } from "fck-trycatch";

const main = async () => {
    const [fetchErr, res] = await attempt(fetch, null, "/someurl");

    if (fetchErr) {
        console.error(fetchErr);
        return;
    }

    const [parseErr, data] = await attempt(res.json, res);

    if (parseErr) {
        console.error(parseErr);
        return;
    }

    console.log(data);
};

main();
