i have started explore node.js , wondering user data stored if wanted create registration form/login , logout functionality website.

i know php form data written , stored sql database on server.

what happens when start use node.js authentification packages. still need set sql database on server? or work in different way? usernames, passwords , reg e-mails stored?

rather confused eager learn node.js , make simple working registration form.

thanks guys!

form data isn't stored (not unless you've handled stored).

when submit form, you're creating http request, , http request, server can designed handle data send said http request...

so, lets made form this:

<form method="post" action="/register">   <input type="text" name="email">   <input type="submit"> </form> 

through magic in browser, when click submit, creates http request where-ever action parameter pointing to.

so, can handle data server-side in our nodejs:

(lets we've made method serve form @ // ...):

http.createserver(function(req, res){    // ...    if (req.method === "post") {     // it's post request, lets gather data     var chunks = [], data = "";     req.on("data", function(chunk){       chunks.push(chunk.tostring());     });      req.on("end", function(){       data = chunks.join();        // handle data here...  save it, whatever need.     });   } });
