Package description

What is p-try?

The p-try npm package is used to start a promise chain and execute a function asynchronously. It is a simple utility that allows you to attempt to execute a function and return a Promise that resolves with the function's result or rejects if the function throws an error.

What are p-try's main functionalities?

Asynchronous function execution

This feature allows you to execute a function asynchronously and handle the result or error using promise chaining.

const pTry = require('p-try');

pTry(() => {
  return 'result';
}).then(result => {
  console.log(result); // 'result'
}).catch(error => {
  console.error(error);
});

How is it useful?

Install

npm install p-try

Usage

import pTry from 'p-try';

try {
	const value = await pTry(() => {
		return synchronousFunctionThatMightThrow();
	});
	console.log(value);
} catch (error) {
	console.error(error);
}

API

pTry(fn, ...arguments)

Returns a Promise resolved with the value of calling fn(...arguments). If the function throws an error, the returned Promise will be rejected with that error.

Support for passing arguments on to the fn is provided in order to be able to avoid creating unnecessary closures. You probably don't need this optimization unless you're pushing a lot of functions.

fn

The function to run to start the promise chain.

arguments

Arguments to pass to fn.
