Topic:
JavaScript;Scripting Languages;Apache Web Server
Recenty, I found one name of Node.js and I review and google it
and found some video and article about Node.js such as
http://dojotoolkit.org/documentation/tutorials/1.8/node/
http://blog.modulus.io/absolute-beginners-guide-to-nodejs
stackoverflow.com/questions/2353818/how-do-i-get-started-with-node-js
http://www.youtube.com/watch?v=jo_B4LTHi3I
And just conclude something from my understanding that is
1-Node.js is server-side javascript platform
2-Create Http request on server--side by client without apache on server , Is it Right?
That is what I know, but all related article or video doesn't mention
what is advantage of using Node.js
So I guess that is
Normally on browser webpage those Javascript code is at client-side so
user can run the code on its computer browser and can be viewed those code by
browser view source option.
And If we are using Node.js , we can put those javascript code into server side
and browser user can run it but from server and users can't veiw ths code.
I think that is good thing if so since we can write some javascript code saved
into server and also let user run it at server side so that
If not, I don't see anything from Node.js to improve my application and website security
If you know the Node.js behind, please let me know what is advantage and application
we can feel using Node.js, for similar example, what is advantage of using
facebook that is you can share or broadcast your information with others.
And I think Node.js should focus on telling people what advantage of using it first
before just all the time mention the code syntax
Please advise
Duncan

Browser user could NOT copy and could not view the code that is good for software security that has similar feature as php coding on server-side
Is it right what I wrote above ?

To run node.js, you have to have your own server because you have to install it as a program. And it requires 'root' access to read files and access the network.
On shared hosting, all of that is set up for you and you don't need 'root' access and usually can't even get shell or command line access much less install a program.
When first installed, node.js does not do anything at all. You have to add functions to it to make it do things. There are libraries and a package manager available to help you.

online game application should run on user browser, Right ?
yes, that's why I say your question don't apply to nodejs
Could you explain it more.
What consuming lot of time and ressources is client-server request
using nodejs you should reduce the number of client-server request especially in a peer to peer game because it's easy to play with JSON for example
nodejs is not as fast as java or php for calculation and memory management is less powerful

where are you running the game? in the user browser so it don't apply...
if you've multiple users playing on the same board in a peer to peer game, nodejs should be good
if you've lot and complex calculations or intense memory usage, it's not good

And online Game Application might not be good in speed from
using javascript/Node.js at server side than javascript at client-side
using javascript/Node.js at server side than javascript at client-side
You think So ?

Thanks for your reply, that is a good start for Node.js study

But Javascript at server-side will be running slower than Javascript at
client side, Right ?
client side, Right ?
if you've the latestS Xeon on the server and your user run on a Pentium 1 I don't think... but it's not the question, it's not because you've javascript running on the server that you need to remove or don't user it on the client side;
using javascript on the server may help you remove some boring part on the client side for example when you need to query external ressource and process, you can save time and client-server requests

Browser User could not view the Node.js javascript code on server, Is it Right ?
yes, of course they CAN'T
And so what is advantage of using Node.js ?
java, php, .net can't easily play with DOM
java, php, .net can't easily read, delete, add data from a JSON structure to a database
java, php, .net don't easily allow you to create a web service

what I like :
- javascript everywhere, when I send data, I don't need to fight, I simply use the data as they come no need to unserialize, serialize. Additionaly, using MongoDB simplify the storing of data, MongoDB is a "JSON database", to store I use a very simple javascript method
- javascript is good to play with DOM
- You should be able to use any Javascript plugin, for example you can use jQuery (not yet directly on windows), YUI, that mean you can build page on the server side using a javascript framework!
1-Node.js is server-side javascript platform
yes
2-Create Http request on server--side by client without apache on server , Is it Right?
yes
the question is how and why do you choose PHP instead Java or ASP.NET?
