zbus strives to make Message Queue and Remote Procedure Call fast, light-weighted and easy to build your own service-oriented architecture for many different platforms. Simply put, zbus = mq + rpc.

zbus carefully designed on its protocol and components to embrace KISS(Keep It Simple and Stupid) principle, but in all it delivers power and elasticity.

zbus-js

• zbus's javascript works for both Browser and NodeJS environments.
• zbus.js is the only source file required in browser

Getting started

Start zbus, see https://gitee.com/rushmore/zbus

1. NodeJS

npm install zbus

you are ready to go

2. Web Browser

just include zbus.js

API Demo

Only demos the gist of API, more configurable usage calls for your further interest.

Produce message

const client = new MqClient("localhost:15555");     

client.connect().then(()=>{
    var msg = {
        cmd: 'pub',
        mq: 'MyMQ',
        body: 'hello from js'
    };
    client.invoke(msg).then(res=>{
        console.log(res);
    });
});  

Consume message

const client = new MqClient("localhost:15555");  

var mq = "MyMQ", channel = "MyChannel"; 
function create(mq, channel){ 
    var msg = {};
    msg.headers = {
        cmd: 'create',
        mq: mq,
        channel: channel, 
    }; 

    client.invoke(msg).then(res=>{
        console.log(res);
    }); 
}

function sub(mq, channel){
    var msg = {};
    msg.headers = {
        cmd: 'sub',
        mq: mq,
        channel: channel, 
    }; 
    client.invoke(msg).then(res=>{ 
        console.log(res); 
    }); 
}  

client.addMqHandler(mq, channel, msg=>{ 
    console.log(msg); 
});

client.onopen = ()=>{
    create(mq, channel);
    sub(mq, channel);
};

client.connect();

RPC client

const rpc = new RpcClient("localhost:15555");     

var res = await rpc.example.plus(1,2);
console.log(res); 

RPC service

class MyService{
    plus(a, b) {
        return parseInt(a) + parseInt(b);
    } 
    echo(value) {
        return value;
    }  
    testEncoding() {
        return "中文";
    } 
    stringArray() {
        return ["hong", "leiming"];
    } 
    getBin() {
        return new Uint8Array(10);
    }  

    getOrder(){
        return {name: 'orderName', age: 18};
    } 

    html(){
        var res = new Message();
        res.status= 200;
        res.headers['content-type'] = 'text/html; charset=utf8';
        res.body = "<h1>hello html body</h1>"
        return res;
    } 
}       

var p = new RpcProcessor(); 
p.mount("/example", new MyService());
p.mount("/", home);

//RPC via MQ
var server = new RpcServer(p);
server.mqServerAddress = "localhost:15555"; 
server.mq = "/";  //mount to root directory of zbus server
server.mqMask = Protocol.MASK_DELETE_ON_EXIT;
//If auth requried
//server.enableAuth("2ba912a8-4a8d-49d2-1a22-198fd285cb06", "461277322-943d-4b2f-b9b6-3f860d746ffd"); //apiKey + secretKey 
server.start();
