Super simple streaming responses for Connect/Express.
npm install streamableHave you ever wanted to utilize Content-Encoding: chunked in XHR, without waiting for the entire request to complete? With Streamable, you can!
install Streamable using npm:
``
npm install streamable
Streamable assumes you're using Express/Connect as your HTTP server, and Socket.io as an async socket connection to the browser.
`js
// setup a basic express 3.x server
var express = require('express');
var app = express();
var server = require('http').createServer(app);
// setup a basic socket.io server
var io = require('socket.io').listen(server);
`
Once we've setup our server-side dependencies, we need to require streamable. Streamable requires knowledge of our socket.io instance.
`js`
var streamable = require('streamable').streamable(io)
Now that we're all configured, we can start using streamable in our REST API.
`js`
app.get('/foo', streamable, function(req, res) {
res.write({foo: 'bar'});
res.write("whatever data I want");
res.write("multiple", ["arguments", "work", "too"]);
res.end();
});
Server-side is ready to go.
Streamable assumes you have jQuery and Socket.io available to your browser, so make sure they are included in page before streamble's client.js.
Once you've included everything you need, add this to your HTML:
`html`
the onData call will happen n times--once per write. The onEnd call is guaranteed to be called one time after all onData and/or onError events have fired. If you've passed multiple values to write on the server-side, you can expect them as arguments in the same order of your onData` event handler.
