Flow-read NPM | npm.io

flow-read

Thin wrapper for graceful-fs file read stream.

Installation

$ npm install flow-read

API

To create a readStream factory,

var readStream = require( 'flow-read' ),
	rStream = readStream();

rStream.path( filepath )

This method is a setter/getter. If no filepath is provided, returns the filepath. You configure the stream factory by specifying a filepath:

rStream.path( 'path/to/file' );

rStream.stream( clbk )

Provided a filepath has been specified, to create a new readStream:

var stream = rStream.stream( clbk );

Where the optional clbk is invoked upon stream end and has an error as its first argument. If no read errors, error is null.

Usage

Methods are chainable:

readStream()
	.path( 'path/to/file' )
	.stream( clbk )
	.pipe( process.stdout );

Examples

// File read stream generator:
var readStream = require( 'flow-read' );

// Create a new stream, passing along an optional error handler:
var stream = readStream()
	.path( __dirname + '/path/to/file.json' )
	.stream( onError );

// Pipe the stream:
stream.pipe( process.stdout );

// Error handler:
function onError( error ) {
	if ( error ) {
		console.error( error.stack );
		throw new Error( 'Error!!!' );
	}
	console.log( 'Finished!' );
