fs-readfile-promise
Promises/A+ version of fs.readFile
const readFile = require('fs-readfile-promise');
readFile('path/to/file')
.then(buffer => console.log(buffer.toString()))
.catch(err => console.error(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
API
const readFile = require('fs-readfile-promise');
readFile(filename [, options])

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.
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);
