Functional try-catch wrapper for promises.

Install

``
npm i try-to-catch
`

API

$3

Wrap function to avoid try-catch block, resolves [error, result];

$3

Simplest example with async-await:

`js
import {tryToCatch} from 'try-to-catch';

const reject = Promise.reject.bind(Promise);
await tryToCatch(reject, 'hi');
// returns
// [ Error: hi]
`

Can be used with functions:

`js
import {tryToCatch} from 'try-to-catch';

await tryToCatch(() => 5);
// returns
[null, 5];
`

Advanced example:

`js
import {readFile, readdir} from 'node:fs/promises';
import {tryToCatch} from 'try-to-catch';

const [error, data] = await tryToCatch(read, process.argv[2]);

if (error) {
console.error(error);
process.exit(1);
}

console.log(data);

async function read(path) {
const [error, data] = await tryToCatch(readFile, path, 'utf8');

if (!error)
return data;

if (error.code !== 'EISDIR')
return error;

return await readdir(path);
}
