unic

unic is a node.js session manager with some advanced features like one session by user, remote disconnect,...

How does it work

unic is a server side session manager. Frontend/backend communication is done using HTTP. unic permits to:

• register a user (but does not check password, this should be done elsewhere) and create a session to store credentials.
• It permits to autorize only ONE session simultanously for a user. If you try to open a second session from another browser, you will get an error message.
• You can chose to force login and disconnect remotly the user from other location.
• Close the session and abandon all data stored in it.
• You can chose a language for error messages. Currently english(en, default language) and french (fr) are supported but other languages can easily be added. This is done using internationalisation package qamoos. As language is stored as a session variable, you should activate session management by using express-session middleware.

Almost all the actions return an object in the form of {err: errorCode, msg : message}

Example of use

app.js

var express = require('express');
var app = express();
var expressSession = require('express-session');
var uniC = require('uniC');

app.use( expressSession({secret:'mySecretKey', cookie: { maxAge: 60000 }, resave:false, saveUninitialized:true}) );

// getLogin gives the current connected login.
function getLogin(req,res){
    res.status(200).json(uniC(req).getLogin() || null).end();
}

// get the value stored in the session  (this could be any objet containing useful information about the user or the session, timestamp,..)
function getStoredValue(req,res){
    res.status(200).json(uniC(req).get()).end();
}

// signin and store a value in the session
function signin(req,res){
    var force = !!parseInt(req.params.force);
    res.status(200).json(uniC(req).signin( req.params.login , force , {} )).end();
}

function signout(req,res){
    uniC(req).signout();
}

// guard is currently similar to getLogin
function guard(req,res){
    res.status(200).json(uniC(req).guard()).end();
}

// change the current language for this session.
// All qamoos in this session will switch to the new language
function lang(req,res){
    uniC(req).lang(req.params.lang);
}

The third argument of the signin method is any object that will be stored in the session. It can be obtained with the .get() method.
