API

const readFiles = require('read-files-promise');

readFiles(filenames [, options])

filenames: Array of String (file paths)
options: Object or String (same as fs.readFile's second argument)
Return: Object (Promise)

It reads the files specified in its first argument.

When it finish reading all the files, it will be fulfilled with an array of the contents as its first argument. The order of the contents depends on the order of file paths.

It won't reject unless it fails horribly. Finding zero files can be a success.

const readFiles = require('read-files-promise');

readFiles([
  'path/to/file0' // 'a'
  'path/to/file1' // 'b'
  'path/to/file2' // 'c'
]).then(onFulfilled, onRejected);

function onFulfilled(buffers) {
  buffers; //=> [<Buffer 61>, <Buffer 62>, <Buffer 63>]
};

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