p-try
Advanced tools
Package description
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.
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);
});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 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 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.
