[nodejs] replacing PHP with node.js
I am in the processing rearchitecting my web site. Currently it is Apache and PHP on the back and Javascript on the client side. Can I just rewrite my php scripts in node and just change the javascript call the node scripts or do I need more infrastructure software? Does apache have a node plugin or how will that work?

thank you for your reply.
At this point I am trying to validate my assumptions and my understanding
of the big picture and data flow.

[nodejs] node.js and front end JS code
I am not understanding the data flow from the client side JS and back end node.js code. So I am developing a web app, my first one ever :) Here is how I am envisioning it, the client is browser based, one URL only... I have a node script that is my web server, index.js, starts listening on . I do not want this script to return HTML text, does it not have to return a HTML filename and not the content? I thought that UI representation and details are done in a file, HTML and javascript. That being the case, the node should return the name of that file. Am I not understanding this correctly? As far as the code running on the server, we should have a web server, I am creating a very light weight one with node itself. The other piece is business logic, I am doing that in various node scripts. No knowledge of HTML file details cooked into node code. All of the example I see Hello world HTML text getting send back for the first page. I want to send that index.html. How does one do that? or I am missing the spirit of node? -- -- 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.

[nodejs] node.js only web site
Is it possible to service a web site with node.js only or do I have to have a web server of sort such as express.js? Here is what I am trying to do. I have a web application, HTML and javascript only on the client side. It is all in one URL... like gmail like... I have my index.html page, my login page. I have an index.js that is my web server running on 8080. It reads the index.html page and sends it to the browser. Great so far. Now on the form, the user puts in username and password and presses login button, the javascript needs to call a node script, let's call it login.js. It will return a JSON saying success or failure. So do I just create the login.js in the same directory as the index.js and I am done? or do I need more framework/plumbing for the javascript to call other node scripts? I do not have any routing since it is all one page. Correct?

soap.createClient(url, *function*(err, client) {

What am I missing?

Re: [nodejs] wsdl file and node.js
changed the code and implemented your suggestions:
*var* soap = require('soap');
*var* url = 'http://www.webservicex.net/stockquote.asmx?WSDL';
*var* args = {
symbol : 'AMZN'
};
soap.createClient(url, *function*(err, client) {
client.GetQuote(args, *function*(err, result) {
*if* (err) {
console.log(err);
*return*;
}
console.log(result);
});
});
and in the console all i see is
{ GetQuoteResult: [ 'exception' ] }
Thoughts?

[nodejs] Re: wsdl file and node.js
if I change the wsdl function to some invalid, I get an exception about a
bad function
so the GetQuote is correct and the result, not the error, is
GetQuoteResult [ exception].
Any ideas? I am really stumped.

[nodejs] node.js and promise
I am a fairly new to javaScript and node.js both. I am trying to wrap my head around promises and I am having a hard time. I am looking for a very simple tutorial/video on this topic and having little success. Is there a reference that can be recommended? A before and after code snippet can be a good starting position.

[nodejs] Re: node.js and promise
we all of this I still can not figure out how to take an async function and change it from callback to a promise. 1. Do I have to declare a promise before I can call a 'then' on it? Every time I do not and call a then on an async function, I get a syntax error.

Re: [nodejs] node.js and promise
Let us use an example:
var q = require('q');
var myAsyncFunction = function(err, result) {
if (err)
console.log("We got an error");
console.log("Success");
};
myAsyncFunction().then(function () { console.log("promise is working");
});
myAsyncFunction().then(function () { console.log("it really worked"); });
^
TypeError: Cannot call method 'then' of undefined
How do I turn myAsyncFunction into a promise?

[nodejs] node.soap client gettings [Error: DEPTH_ZERO_SELF_SIGNED_CERT] error
I have a node app using the soap module, node-soap. I am creating a soap
client using a URL. On the mentioned URL, there is a self signed
certificate and it is causing a [Error: DEPTH_ZERO_SELF_SIGNED_CERT]. I am
not finding much on this but is there is any setting I can tweak for this
client to get around this error?
My code is the following:
var url3 = "https://172.31.19.39/MgmtServer.wsdl";;
var args3 = { "user": "admin-priv", "password":"password"};
soap.createClient(url3, function(err, client) {
if (err) {
console.error(err);
return;
}
console.log(client.describe().MgmtServer.MgmtServer.mgmtValidatePassword);
client.MgmtServer.MgmtServer.mgmtValidatePassword(args3, function(err,
result) {
if (err) {
console.error(err);
return;
}
console.log(result);
});});
the output is [Error: DEPTH_ZERO_SELF_SIGNED_CERT] [Error:
DEPTH_ZERO_SELF_SIGNED_CERT]
Any way to deal with this? the certificate is a valid, not expired, self
signed certificate

[nodejs] Re: node.soap client gettings [Error: DEPTH_ZERO_SELF_SIGNED_CERT] error
Added
process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';
now I get past that error, I get the client.describe and the client call
fails.
The code is
var url3 = "https://172.31.19.39/MgmtServer.wsdl";;
var args3 = { "user": "admin-priv", "password":"password"};
soap.createClient(url3, function(err, client) {
if (err) {
console.error(err);
return;
}
console.log(client.describe().MgmtServer.MgmtServer.mgmtValidatePassword);
client.MgmtServer.MgmtServer.mgmtValidatePassword(args3, function(err,
result) {
if (err) {
console.error(err);
return;
}
and the output is now
{ input: { user: 'xsd:string', password: 'xsd:string' },
output:
{ rsp:
{ nsName: 'complexType',
namespace: 'ns',
name: 'complexType',
children: [Object],
xmlns: 'urn:MgmtServer',
'$name': 'MGMT-RESPONSE-S' } } }
{ [Error: connect ECONNREFUSED]
code: 'ECONNREFUSED',
errno: 'ECONNREFUSED',
syscall: 'connect' }
{ [Error: connect ECONNREFUSED]
code: 'ECONNREFUSED',
errno: 'ECONNREFUSED',
syscall: 'connect' }
not sure where the ECONNREFUSED is caused by.
Thoughts on this?

In index.js which is part of the request package, I see this line request.debug = process.env.NODE_DEBUG && /request/ .test(process.env.NODE_DEBUG) how do I make sure the second part is true, /request/.test(process.env.NODE_DEBUG that is? This is how they are testing if something gets logged to the console or not. Any ideas? -- -- 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.

Re: [nodejs] how to get a console output to show up (from the request package)
thanks for the response. How do I do that in the code itself? and how do I do multiple ones? lets say debugging for http and request and xyz package.

[nodejs] syntax error is node-soap (debug) script when NODE_DEBUG is set
Just learned how to use the NODE_DEBUG env settings. Now I get a syntax
error in
./node_modules/soap/node_modules/request/lib/debug.js
module.exports =
function debug () {
if (/\brequest\b/.test(process.env.NODE_DEBUG))
console.error('REQUEST %s', util.format.apply(util, arguments))
}
ReferenceError: util is not defined
Any ideas what the issue might be? Does not look like this code can ever
work if the NODE_DEBUG is set correctly.
Thoughts?

[nodejs] how to create a singleton
A newbie question... I have an app that connects and reuses the same connection to a remote database and a connection to a remote soap server. I want to implement a singleton pattern for each of these. I am used to doing that in C++ and Java but want to know what the standard implementation for a Singleton pattern is in node.js.

[nodejs] Re: how to create a singleton
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.

[nodejs] Re: how to create a singleton
Awesome that works wonderfully. Thanks. One more issue that you have an idea on, is that in getInstance I have to make an async call. It creates a soap connection and that is only supported in async mode. Any thoughts on how to structure that code?

Re: [nodejs] Re: how to create a singleton
I could then it would get ugly, because now whoever calls getInstance have to provide a callback.

Re: [nodejs] Re: how to create a singleton
this I get the jist of the conversation but my Javascript skills, less than 2 months, does not allow me to be able to code this up. Also, as a starter in the new language the last thing I want to do is to miss out on the language correct way of things and force lets say the Java way of doing things in JS. Can you show me a skeleton of such function and a tiny consumer of that? The reason I say that is the fact that all of the examples are all done in the same JS file and not setup as module and when I try to change to a module and a consumer, I run into syntax problems and I do not understand the difference between a class exporting an object as opposed to a constructor Thank you so much for showing me the correct way On Thursday, November 21, 2013 7:37:32 AM UTC-8, Kamil Leszczuk wrote: > > Aah, nevermind then, I misunerstood ;) > 21 lis 2013 16:36 "Gregg Caines" > > napisał(a): > >> Yeah... that's what I'm saying :) >> >> G >> >> >> On Thu, Nov 21, 2013 at 7:33 AM, Kamil Leszczuk >> >> > wrote: >> >>> > For example, if I have a module for emailing with a send() method on >>> it, I don't have it export a constructor; I have it export an object.

returns the connection, or SoapClient.instance...

My original intent is for the consumer of this object is to use the "client" synchronously on demand, as opposed to async.

[nodejs] define is not defined errot
so I am trying to export a class constructor... This is what I have done
based on my readings.
define('SystemVersionResponse', function() {
function SystemVersionResponse(input) {
this.errorMessage = String.fromCharCode.apply(String,
input.rsp.rsp.errorMessage.item).replace(/\0/g,'');
this.errorNumber = input.rsp.rsp.errorMessage.errorNumber;
}
SystemVersionResponse.prototype.getErrorCode = function() {
return errorNumber;
};
SystemVersionResponse.prototype.getErrorMessage = function() {
return errorMessage;
};
SystemVersionResponse.prototype.getRevision = function() {
return revision;
};
return SystemVersionResponse;
});
I get the syntax error:
ReferenceError: define is not defined
What package am I missing?
Is this the correct way to export a constructor?

[nodejs] node programming style question
I see both style and trying to understand the differences... Debugging,
logging, other plus or minus...
Option one:
var zero = function (n){
return n < 10 ? "0" + n : n;
};
Option two:
function zero (n){
return n < 10 ? "0" + n : n;
};
What is the "recommended" style and why?

[nodejs] how to implement a rollback functionality for a set of asynchrous calls
So I have a node server making calls to a SOAP server. All are asynchronous as one would expect. The node server will get a list of commands to run, each will translate to one async call. The rule is start running the commands until the list is complete or one leads to an error, i.e. a command that fails. In the case of the failure, need to rollback all the succeeded commands, really identical to a SQL transaction. The commands will have to be rolled back, in the reverse order, to ensure system integrity. Up to now, I did not have the rollback feature. So far I was using async.series with a callback for each of my commands. My commands are very analogous to SQL commands, to help picture what I need to do. Any simple ways to implement the rollback?

[nodejs] how to synchronize two async.waterfall calls
I have a set of read commands that I have to in sequence. Any fails,
processing stops.
readCommands is an array of read functions...
async.waterfall(readCommands, function(err) {
if (err) {
console.log(err);
res.send(500, { error : err.toString() });
return;
}
else {
console.log('we determined the state to which we have to
rollback to');
}
});
at this point, I know what I started with. Now I want to do the write
commands
async.waterfall(writeCommands, function(err) {
if (err) {
console.log(err);
res.send(500, { error : err.toString() });
return;
}
else {
console.log('we succeeded with all the write commands...');
}
});
the arrays readCommands and writeCommands entries are radically different
so very hard to combine them. But I DO for the first waterfall to finish
before I go to the next one.
How do I make a "waterfall" out of the existing two?

[nodejs] logging with rconsole question
I am prototyping logging for my node.js application and started with
rconsole package. Not clear how to set the logging levels. I have the
following code and regardless of what debug level I set, I see the same
output.
require('rconsole')
console.set({
facility: 'local0' // default: user
, title: 'web-01' // default: node -- can also be set with
`process.title`
, highestLevel: 'err' // [emerg, alert, crit, err, warning, notice, info,
debug]
, stdout: false // default: false
, stderr: true // default: true
, syslog: true // default: true
, syslogHashTags: false // default: false
, showTime: true// default: true
, showLine: true// default: true
, showFile: true// default: true
, showTags: true// default: true })
console.warn('level is set to err and this is a warn');
console.notice('notice');
console.error('error');
console.set({
highestLevel: 'notice',
stderr: false
})
console.warn('level is set to notice warn and this is a warn');
console.notice('notice');
console.error('error');
console.set({
highestLevel: 'crit',
stderr: false
})
console.warn('level is set to notice crit and this is a warn');
console.notice('notice');
console.error('error');
and the output, I always see the same output which is
level is set to err and this is a warn
notice
error
level is set to notice warn and this is a warn
notice
error
level is set to notice crit and this is a warn
notice
error
Can someone explain to me what I am doing wrong here?

same output, no change after using error. This is on a Mac, I do not thin

Except this server is not very reliable and crashes some time :( So at some point during the run, I make a call and I get socket connection error. What is a standard customary, pattern, to deal with this issue.

[nodejs] callback hell on steroid
I have a node.js, express really, app that needs to make SOAP calls, asynchronously of course. In this case, I make a soap call and I get a count. Once i have the count, I have to loop and make a series of SOAP calls for each, this part you can think of this as async.series calls. I have used async waterfall, series, parallel and Q promises; somewhat comfortable with them. How do you suggest I set this up to avoid callback hell and have control over exceptions and the rest. I can not see how this should be laid out. -- -- 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.

[nodejs] chaining a promise and array of promises
I am using Q for my promise library.
I have a promise that if success calls and array of promises.
The code is:
getCount(client).then(function (count) { //
when successful create a
var promises = [];
// array of promises to be processed next
for (var i = 0; i < count; i++) {
// in order
promises.push(az(client, i));
}
return Q.all(promises);
}).then(function(results) {
console.log("everything went right. All results:", results);
}, function(err) {
console.log("something (either getCount, or one of the az
calls) blew up", err);
});
so az takes and index and returns a value. If index === 1 it throws.
function az(client, index) {
var xml = " ";
client.MgmtServer.MgmtServer.asynCall(xml, function (err, result) {
if (err) {
return deferred.reject(err);
}
if (1 === index) {
console.log('index 1 is bad news');
return deferred.reject("Blew up");
}
console.log('returning with index ' + index + ' returning ' +
(index + 30));
deferred.resolve(index + 30);
}
);
return deferred.promise;
};
when I run this, I see this output:
everything went right. All results: [ 3, 3, 3 ]
returning with index 0 returning 30
index 1 is bad news
returning with index 2 returning 32
Output of getCount first then az 1 2 3 and the exception for 1 never
sending me to console.log("something (either getCount, or one of the az
calls) blew up", err);
Am I using my array of promises incorrectly?

Re: [nodejs] node and database connection pool
Matt,
just so I understand, you are saying if a node package such as mongodb
provides connection pooling, they have to be implementing the package using
a pooling system that is implemented in C?

[nodejs] Node.js and cross-domain AJAX requests
I work on a express.js connect and node server. The client is done using AngularJS and it will to make calls to number of different backend node servers.

[nodejs] how to read file from a relative path
So i have a node app and I have the following:
var options = {
key: fs.readFileSync('./server.key'),
cert: fs.readFileSync('./server.crt')
};
This only works if I run the app from these 2 files are.
How do I change my code so that it works regardless of where it is launched
from?
I am looking for the "node" way of doing this. I know I can use an env
variable to get around this.
Thoughts?

[nodejs] Re: can one use socket.io for domain sockets?
I had started looking at that, thank you. So here is what I need to do to communicate to the server. The server has created a UNIX domain socket, lets call it /tmp/connect_to_me and it is listening on it for connections. Lets switch to C++ for a second since the server is in C++ So client attempts to connect to /tmp/connect_to_me, the server accepts that and returns a "file descriptor" to the client for reading and writing... That is what my node client has to do. So now having read the net module, I can net.connect to /tmp/connect_to_me but now I can read and write from the domain socket which is not what I need to do, I need to read and write from the "file descriptor" or stream returned to me by the server. And that is what I am trying to solve. Any thoughts?

[nodejs] how to write to a UNIX domain socket
so my server provide a UNIX domain socket and accepts my connection, from
node.js client.
My code is:var client = net.createConnection("/tmp/SocketServer"); I see
that the server accepted my connection looking at the logs.
next step is for me to write to this socket, or the client variable.
In the debugger, client variable is of type Socket.
I only see EventEmitters for the client. How do I write to it?

[nodejs] jasmine test cases for a SOAP server
I am writing a web server in node and express and most of the routes make SOAP calls. I want to write test cases for my routes. I have enough for my non SOAP call features. So I need to have a mock SOAP server? How would that look?

[nodejs] Re: jasmine test cases for a SOAP server
Right now my soap calls are so deeply nested into my REST routes, I think I have to start pulling those out, and make them more accessible directly. Only then I can mock the specific calls. I was really hoping for a SOAP mock server that I can add the call supports to them but like you said I can simulate that will timeouts and something that returns some fake data. It is not trivial and it is tedious...

[nodejs] node server using 80% CPU
I have a RESTful node server. Clients send requests which all translate to SOAP calls. The SOAP server and node server all both on the same machines. One HTTPS request, all are HTTPS, can translate into up to 7 SOAP calls. When the client puts the auto refresh on, every 5 seconds a series of requests are sent to the node server. With 2 clients, auto refresh on, can add up to two dozens of SOAP calls, the node server, using top, goes up above 80%. How can I determine what is causing this CPU spike? 2 dozens of SOAP calls can cause this? -- Job board: http://jobs.nodejs.org/ New group rules: https://gist.github.com/othiym23/9886289#file-moderation-policy-md Old group rules: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines --- You received this message because you are subscribed to the Google Groups "nodejs" group.

[nodejs] RESTful server and websockets
I feel that a server that provides a RESTFul API should not support websockets connections. Websocket connections implies stateful, server is aware of a persistent connection to a client. A RESTFul server implies that there is no notion of a client, only request and response and nothing more as it pertains to the client. We have a case where the clients, AngularJS code, communicates with a REST node server. Now we have a feature of server "updating" the clients of an event. Client can polls, very frequently, for the event happening. Or enter the websockets and the notion of publisher/subscriber. To provide that and to stay pure to the RESTFul premise, we can add a secondary node server for this purpose of pub/sub model. Am I the only one feeling like mixing RESTful API and websockets is mixing metaphors and should be avoided?

[nodejs] Re: RESTful server and websockets
I feel the way that websockets violate REST principle is the notion of the server knowing about a client and its "state" in the sense that the server is aware of a "persistent" client waiting for to be told of an event. this is different that the REST model of request/response. To me it is mixing stateless and stateful. Agree? On Thursday, August 28, 2014 2:08:35 AM UTC-7, Floby wrote: > > That first answer is right.
