Re: [nodejs] how to create a singleton
Please check Addy Osmani book, Learning Javascript design patterns. http://addyosmani.com/resources/essentialjsdesignpatterns/book/ It has a correct version of singleton implementation On Nov 19, 2013, at 1:38 AM, Reza Razavipour reza.razavip...@gmail.com wrote: A newbie question...

Re: [nodejs] Re: how to create a singleton
yeah that's right. You just need to add the line
module.exports = mySingleton
and in the caller file require as follows
var singleton = require('./single').mySingleton
Hope that helps

Wonderful book, thank you.
So reading the book, if I put the code for the mySingleton class into a file
on its own, call it single.js.
In my main.js, I add that with a require statement, such as var singleton =
require('./.single);
when I say, singleton.getInstance(), I get a compile error saying singleton
does not have a getInstance function...
Do I have to add an export to the single.js file I created or what am I
missing...
The code is as follows:
var mySingleton = (function() {
var instance;
function init() {
var privateRandomNumber = Math.random();
return {
publicMethod : function() {
console.log(The public can see me!);
},
publicProperty : I am also public,
getRandomNumber : function() {
return privateRandomNumber;
},
getInstance : function() {
if (!instance) {
instance = init();
}
return instance;
}
};
};
return {
getInstance : function() {
if (!instance) {
instance = init();
}
return instance;
}
};
})();
Thanks for the help.

Re: [nodejs] git server built with node
Hi Quinton, Took a look at gitserver. Interesting. I'd love to see some comparisons to gitolite, especially how flexible it is to manage permissions and add hooks. good job anyway On Apr 18, 2013, at 10:51 PM, Quinton Pike qrp...@gmail.com wrote: I am building a NodeJS multi-tenant git server based on pushover.

Re: [nodejs] Node.js under OSX
Hi Bodo, choosing Homebrew over Mac Ports was the right thing to do as far as I can tell. I made the change about two years ago and have never regretted it. Anyway, node.js on os x works just fine for me José On 3 Aug 2012, at 10:56, kyogron kyog...@googlemail.com wrote: Hi, I have now switched from GNU/Linux to Mac OSX.

[nodejs] - Github Followers Thread
Hi all, below is the github link to a project I have been working on on and off for a few months now. Unfortunately I haven't deployed it yet because (a) there still are a few use cases to complete, (2) the deployment is kinda tricky in that I need both an account to host git repositories and a server to host the riak db. I am still thinking about the best option. Any suggestion is welcome. https://github.com/joques/the_fellow_ship José -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups nodejs group.
