JetBus 介绍
Jet 是一个用于 Web 的轻量级和实时的消息总线。支持浏览器和 Node.js node-
jet，提供 Lua 版本 lua-
jet 和基于 Arduino 的版本 Arduino-
Jet。
示例代码：
var jet = require('node-jet');
var peer = new jet.Peer({
url: 'ws://jet.nodejitsu.com:80'
});
peer.connect().then(function() {
console.log('peer is connected to daemon');
});
var machineName = new jet.State('machine/name', 'animal');
machineName.on('set', function(newName) {
setMachineName(newName); // does something appropriate
});
peer.add(machineName).then(function() {
console.log('machine/name has been added to daemon');
}).catch(function(err) {
console.log('could not add machine/name to daemon', err);
});
// add a state
var cpuLoad = new jet.State('cpu/load', readCpuLoad());
peer.add(cpuLoad).then(function() {
// async post new value
setTimeout(function () {
cpuLoad.value(readCpuLoad());
},3000);
});
添加方法：
// add a method
var greet = new jet.Method('greet');
greet.on('call', function(name) {
if (name.first === 'John') {
throw 'John is a bad guy!';
}
var greeting = 'Hello ' + name.first + ' ' + name.last;
console.log(greeting);
return greeting;
});
peer.add(greet);
