does-exist

Promising module to test for existence of a file/directory adherent to best-practices defined within nodejs.org documentation.

Assumes Node 6+

Simple featureless convenience utility to asynchronously determine if a file or directory exists at the provided path. Follows the implementation suggested in the Node.js FileSystem documentation, with the result returned via a Promise.

Usage

From Node:

const doesExist = require('does-exist');

doesExist(pathToFileOrDir)
  // if pathToFileOrDir exists, promise resolves to true (otherwise false)
  .then(result => console.log(result))
  // if a non-ENOENT error is thrown, the promise is rejected passing the thrown error
  .catch(console.error.bind(console));

From command line:

$ exists path-to-file

Installation

Install via npm:

$ npm i does-exist

Tests and Coverage
