p-try Build Status

Start a promise chain

How is it useful?

Install

$ npm install p-try

Usage

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

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

API

pTry(fn, …args)

Returns a Promise resolved with the value of calling fn(...args). 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.
