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);
});Other packages similar to p-try
bluebird
Bluebird is a full-featured promise library with a focus on innovative features and performance. It includes utilities for converting callback-based APIs to promises, advanced error handling, and concurrency helpers. Compared to p-try, Bluebird is more feature-rich and can be used for a wider range of promise-related tasks.
q
Q is one of the earliest promise libraries for JavaScript. It provides a robust set of features for creating and managing promises. While Q is more comprehensive than p-try, it is also larger in size and may be more complex for simple use cases where p-try would suffice.
es6-promise
ES6-Promise is a polyfill for the ES6 Promise specification. It provides the basic functionality needed to work with promises in environments that do not support them natively. Unlike p-try, which is a utility for starting promise chains, ES6-Promise is focused on implementing the standard Promise API.
Readme
p-try
Start a promise chain
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.
