fs-readfile-promise

fs-readfile-promise

Promises/A+ version of fs.readFile

var readFile = require('fs-readfile-promise');

readFile('path/to/file')
.then(buffer => console.log(buffer.toString()))
.catch(err => console.log(err.message));

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

Installation

Use npm.

npm install fs-readfile-promise

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

const onFulfilled = buffer => console.log(buffer.toString());
const onRejected = err => console.log('Cannot read the file.');

readFile('path/to/file').then(onFulfilled, onRejected);
