node-stream-grab-string
Quick-and-dirty function for extracting a string from a Node text stream
Installation
npm install grab-string
Usage
var grabString = require('grab-string');
var input = fs.createReadStream('README.md');
var output = fs.createWriteStream('copy-of-README.md')
input
.pipe(grabString(console.log))
.pipe(output);
//prints the contents of README.md to the console, and also writes them to copy-of-README.md
//note that console.log is only called once
Notes
This should not be used on a real system, this is just a quick shortcut for non-performance-intensive tasks.
