socket.io-context
Advanced tools
Provides updatable JS object (shared context) on top of socket.io connection in unobtrusive way.
npm install socket.io-context
Server side:
var io = require('socket.io-context');
var ws = io.Context(http, {
// custom options here, will augment ws.settings
});
ws.on('connection', function(client) {
//
// N.B.
// `client` here is vanilla connection socket augmented with
// `.update()` method which allows to mangle the shared context
// at any level of depth
//
// define some context properties
//
client.update({
foo: 'bar',
deep: {
method: function(a, b, c, fn) {
fn(a + b + c);
}
},
callme: function() {
this.browser.callme('hello from server');
}
});
});
Client side:
<script src="/socket.io/socket.io.js"></script>
<script>
// connect
var client = io.Context({ /* socket options here, if any */ });
var server = client.context;
// N.B. `server` has now property `foo` set to `'bar'`
// along with property `deep` which has property `method` which is
// truly callable
// call remote method
server.deep.method(1, 2, 3, function(result) {
console.log('deep.method(1, 2, 3) resulted in ', result);
});
// update shared context
client.update({
// replace `foo`
foo: 'baz',
// augment `deep`
deep: {
// with stolen cookies ;)
cookies: document.cookie
},
// define `browser`
browser: {
callme: function(text) {
alert(text);
}
}
}, null, function() {
// N.B. update is async process so continuation style is allowed
// now context is updated and we can call remote method which
// calls back `browser.callme` method
server.callme();
});
</script>
In short, whatever you like. Have fun and profit.
