$ npm install arraystream

Usage

with Array

var ArrayStream = require('arraystream');
var stream = ArrayStream.create(['hoge', 'fuga', 'piyo']);

stream.on('data', function(value, key) {
  console.log(value); // hoge, fuga, piyo
  console.log(key);   // 0,    1,    2
});

stream.on('end', function() { // emitted at the end of iteration
  console.log('end');
});

stream.on('error', function(e) { // emitted when an error occurred
  console.log(e);
});

with Object

var ArrayStream = require('arraystream');
var objstream = new ArrayStream({a:'hoge', b:'fuga', c:'piyo']);

objstream.on('data', function(value, key) {
  console.log(key);   // a,    b,    c
  console.log(value); // hoge, fuga, piyo
});

objstream.on('end', function() { // emitted at the end of Object
  console.log('end');
});

objstream.on('error', function(e) { // emitted when an error occurred
  console.log(e);
});

syntax sugar (forEach)

var arr = ['hoge', 'fuga', 'piyo'];
var stream = ArrayStream.forEach(arr, function(value, key) {
  console.log(value); // hoge, fuga, piyo
  console.log(key);   // 0,    1,    2
});

stream.on('end', function() { // emitted at the end of iteration
  console.log('end');
});

stream.on('error', function(e) { // emitted when an error occurred
  console.log(e);
});

arraystream's Issues

Why is on not tolerant stream after an error event an end event emitted?

Can you tell me why you implemented this behaviour? I saw no other readable stream in node.js with this behaviour. I thought in the error event the end is implied.
