Quick Start

No.GDK dose not support quick start.And I will not provide a generator.

I don't think less is best.I can guide you to make your our service different with anyone.

At First make sure that your env is in your project and you npm installed gdk.

You can download Learning Project.

1.Create bin File to guide - bin/start.js

require('gdk')

var baseDir  = __dirname;
gdk.load(gdk.c.path.join(baseDir,'../config'));

gdk.boot();

gdk.load(gdk.c.path.join(baseDir,'../http'));

gdk.cluster(function(){
    gdk.http.boot();
});

2.Create config File - config/index.js

var baseFile = __filename;
gdk.updatePath.config = baseFile;

gdk.config.Mcores = true;
gdk.config.errLog = gdk.c.path.join(__dirname,'../err.log');
gdk.config.port = 3000;

3.Create http base - http/index.js

gdk.updatePath.http = __filename;
gdk.http = {};

gdk.load(gdk.c.path.join(__dirname,'./router'));
gdk.load(gdk.c.path.join(__dirname,'./flow'));
gdk.load(gdk.c.path.join(__dirname,'./instance'));

4.Create flow file - http/flow/index.js

gdk.http.flow = function(req,res){
  if(gdk.http.router[gdk.c.url.parse(req.url).path]){
    gdk.http.router[gdk.c.url.parse(req.url).path](req,res);
  }else{
    res.end();
  }
}

5.Create router file - http/router/index.js

gdk.http.router = {};

gdk.http.router['/'] = function(req,res){
  res.end('Hello World!');
}

6.Create instance file - http/instance/index.js

gdk.http.server = function(req,res){
    gdk.http.flow(req,res);
};

gdk.http.boot = function(){
    var server = gdk.c.http.createServer(gdk.http.server);
    server.on('error',function(err){
        gdk.errCatch('server err',err);
    });
    server.listen(gdk.config.port);
};

7.Run

node bin/start.js

Command

1.bash command

Example:

bash---console.log(gdk.config)

2.Hot-update command

Example:

update---config

Example2:

upfile---/node/http/index.js

3.Your command

Example:

gdk.runTime.print = function(info){
  console.log(info)
}

print---here is a test

Cluster message I/O

In gdk Cluster mode.gdk.cluster(cb).cb will always run on workers.

Workers can use process.send to call a runtime function in all workers or master.

Example:

gdk.runTime.print = function(a,b){
  console.log(a+b)
}

process.send({bash:'print',arg:{'hello',' world'}});

Example:

gdk.runTime.MainCore = function(a,b){
  console.log(a+b)
}
  
process.send({bash:'MainCore',arg:{'hello',' world'},Master:true});
