Getting started
Installation (browser)
git clone https://github.com/anttisykari/dstream
<script src='dstream.js'></script>
Installation (node.js)
npm install dstream
var stream = require('dstream');
First steps
// Create a source stream
var s = stream();
// You can observe stream's values
s.forEach(function(value) {
console.log('I got a value', value);
});
// You can set its value
s.set(1);
// -> I got a value 1
// You can create a derived stream
var s2 = stream.map(function(value) {
return value * 2;
});
s2.forEach(function(value) {
console.log('s2', value);
});
s.set(123):
// -> s2 246
