Re: [nodejs] define is not defined errot
That’s an interesting opinion, but all nodejs code I’ve ever read makes modules
this way, so that makes it the de-facto nodejs way.

Re: [nodejs] Re: how to create a singleton
Sure that's the common explanation, but don't fall for it: globality has everything to do with it. If the singleton didn't care about creating global state, it could just have `this.created = true;` for its *only* internal state and have thrown exceptions from the constructor for any subsequent calls. That's the simplest way to ensure that only one instance gets constructed. In the browser, where there's no module system to stop your global variables from spraying everywhere, any singleton can just as safely be replaced by a simple single global instance instantiated normally. There's absolutely no difference in control or globality whatsoever, and you get better performance by not making completely unnecessary getInstance() calls just to get your instance. The singleton pattern is really nothing more than a hack to get globals into java via the global class namespace. Even in java, it's pretty common to solve the same problems with IoC containers now instead of singletons, because global state is generally considered A Bad Thing (unless used extremely judiciously).

This is simply not true. By default, module code has access to the `global`
object reference, which allows:
// module.js
global.foo = 1;
// program.js
require("./module.js");
console.log(foo); // 1
There is no implicit global environment bindings created for top level var
declarations or function declarations because the source body of module
code is wrapped in an IIFE:
https://github.com/joyent/node/blob/master/src/node.js#L1007-L1014. Which
is not the same as a unique "namespace" and certainly not the same as
having a fresh realm-like global object.

[nodejs] Streaming audio from avconv via NodeJs WebSockets into Chrome with AudioContext
Hello, we're having trouble playing streamed audio in a browser (using Chrome). We have a process which is streaming some audio (for example an internet radio) on udp on some port. It's avconv (`avconv -y -i SOMEURL -f alaw udp://localhost:PORT`). We have a NodeJs server which receives this audio stream and forwards it to multiple clients connected via websockets. The audio stream which NodeJs receives is wrapped in a buffer which is an array with numbers from 0 to 255. The data is sent to the browser without any issues and then we're using AudioContext to play the audio stream in the browser (our code is based on AudioStreamer - https://github.com/agektmr/AudioStreamer). At first, all all we got at this point was static. When looking into the AudioStreamer code, we realized that the audio stream data should be in the -1 to 1 range. With this knowledge we tried modifying each value in the buffer with this formula `x = (x/128) - 1`. We did it just to see what would happen and surprisingly the static became a bit less awful - you could even make out melodies of songs or words if the audio was speech. But it's still very very bad, lots of static, so this is obviously not a solution - but it does show that we are indeed receiving the audio stream via the websockets and not just some random data. So the question is - what are we doing wrong? Is there a codec/format we should be using? Of course all the code (the avconv, NodeJs and client side) can be modified at will. We could also use another browser if needed, though I assume that's not the problem here. The only thing we do know is that we really need this to work through websockets. The OS running the avconv and NodeJs is Ubuntu (various versions 10-13) Any ideas? All help will be appreciated. Thanks!

Re: [nodejs] Node.js support for Exporting excel and Database
If you use MS-SQL server, would suggest the “tedious” module over the MS one... it’s more portable. You may want to consider PostgreSQL or MySQL if either are an option (I prefer PostreSQL). (based on what your are describing for your data, I would lean towards an SQL database vs a non-relational db... Some use cases are better suited for NoSQL, yours doesn’t seem to be one of them) You can mount endpoints pretty easily with nodejs, though there are some REST frameworks for getting you going faster. For running the application as a service in windows, you’ll likely want to use NSSM (Non-Sucking Service Manager) to create your service entry in windows. For Linux, depends on your distro & version. As for “exporting” to excel if you only need one worksheet would just output to CSV which excel can open (then re-save) fine... if you need more, there are libraries, but they come with a little more overhead. From: Syed Haani Sent: Wednesday, November 27, 2013 4:55 AM To: nodejs@googlegroups.com Subject: [nodejs] Node.js support for Exporting excel and Database I am new to node.js. I am currently in a pre-development phase of an application. The application will be for tracking status of task of employee. The admin will have the right to export excel which will have data of employes for a given date range Currently I am thinking WCF Service and SQL Server for the backend. Few days back, someone told me about node.js and it's capabilities. And yes I was impressed I wanted to know if I write a service with node.js, how will the service be hosted, also if I can write code for exporting data in excel, and lastly which database providers/adapters does node.js support? Apologies if there is typo or this question need to be asked in any other community of stackExchange.

Re: [nodejs] how to create a singleton
of course you could just as easy have done...
//foo module ...
var foo = {...}
module.exports = foo;
//app.js
var foo = require(‘foo’)
all require(‘foo’) with the same library reference will be the same...
the only thing global does is allow multiple versions of libraries not to stomp
on eachother...
//bar module – first to register wins
module.exports = global.__bar__ = global.__bar__ || initModule();
function initModule() {
return {\*...some object...*\};
}
...
which can also be valuable

Sure it does. In browsers you can reference a global easily from any file. In
node, each file gets its own namespace, so you can’t.
This is simply not true. By default, module code has access to the `global`
object reference, which allows:
// module.js
global.foo = 1;
// program.js
require("./module.js");
console.log(foo); // 1
There is no implicit global environment bindings created for top level var
declarations or function declarations because the source body of module code is
wrapped in an IIFE:
https://github.com/joyent/node/blob/master/src/node.js#L1007-L1014. Which is
not the same as a unique "namespace" and certainly not the same as having a
fresh realm-like global object.

Sure, if I was trying to illustrate something that wasn't the thing I was
trying to illustrate. Or if I wanted to confuse my point with something
questionably relevant.
