fs-readfile-promise v3.0.1

fs-readfile-promise

Promisified version of fs.readFile

const readFilePromise = require('fs-readfile-promise');

(async () => {
  const buffer = await readFile('path/to/a/file');
  buffer.toString(); //=> '... file contents ...'
})();

Based on the principle of modular programming, this module has only one functionality readFile, unlike other Promise-based file system modules. If you'd like to use a bunch of other fs methods in the Promise way, choose other modules such as q-io and promise-fs.

Installation

Use npm.

npm install fs-readfile-promise
