stread - stream string

The stread Node.js module makes an utf-8 encoded string readable through the stream API, which can be handy sometimes, while writing tests for streams, for example.

Build Status

Why not use PassThrough?

stread is more than 2x faster than PassThrough:

$ node benchmark.js

Working...

  12 tests completed.

  stread 10           x 57,941 ops/sec ±1.85% (168 runs sampled)

Example

Piping to a writable stream

var stread = require('stread')

stread('You know what it is to be born alone, Baby tortoise!')
  .pipe(process.stdout)

Reading one octet at a time

var stread = require('stread')

var reader = stread('You know what it is to be born alone, Baby tortoise!')
var writer = process.stdout

function write () {
  var ok
  var chunk
  do {
    if ((chunk = reader.read(1)) !== null) {
      ok = writer.write(chunk)
    }
  } while (chunk && ok)
  if (!ok) writer.once('drain', write)
}

write()

Exports

function stread(str)
  • str The String to stream.

Returns a Readable stream.

Installation

With npm, do:

$ npm install stread
