Package Exports

fs-readfile-promise

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fs-readfile-promise) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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
