Promise It Exists
Synopsis
This module checks a filepath to confirm the file exists.
Motivation
Node does not have a one-liner for file validation using promises, so I wrote a module to do the job.
##Installation
$ npm install @johnpaulvaughan/promise-it-exists --save##Code Example Resolves a Promise on success:
let promiseIt = require('@johnpaulvaughan/promise-it-exists');
return promiseIt.exists('testing/good filename.txt')
.then((result) => console.log(result))
.catch((err) = > console.log(err)
// -> 'testing/my good filename.txt'Rejects with an error on failure:
let promiseIt = require('@johnpaulvaughan/promise-it-exists');
return promiseIt.exists('testing/bad filename.txt')
.then((result) => console.log(result))
.catch((err) = > console.log(err)
// -> Error('File does not exist')
