fs-readfile-promise

fs-readfile-promise

Promise version of fs.readFile

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

readFile('path/to/file')
.then(function(buffer) {
  console.log(buffer.toString());
})
.catch(function(err) {
  console.log(err.message);
});

Based on the principle of modular programming, this module has only one functionality readFile, unlike other file system modules using promises. 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

Install with npm. (Make sure you have installed Node)

npm install --save fs-readfile-promise

API

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

readFile(filename [, options])

filename: String
options: Object (same as fs.readFile)
Return: Object (Promise)

When it finish reading the file, it will be fulfilled with an Buffer of the file as its first argument.

When it fails to read the file, it will be rejected with an error as its first argument.

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

var onFulfilled = function(buffer) {
  console.log(buffer.toString());
};

var onRejected = function(err) {
  console.log('Cannot read the file.');
};

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