node-catstream

Filenames go in, contents come out. You can't explain that.

Installation

npm install --save catstream

Usage

catstream is a Transform stream that takes filenames as inputs and outputs the contents of said filenames in the order they were read.

var filenames = [
    'a.txt', // content: hello
    'b.txt', // content: goodbye
    'c.txt'  // content: o rly
];
var cat = require('catstream');
var c = cat()
c.pipe(process.stdout)
c.end(filenames.join('\n'))

// prints "hello goodbye o rly" to the console

more usually you have a readable stream with a list of filenames that you pipe to this.
