Esr-php-session NPM

esr-php-session

A esr-php-session is a session for express, socket.io, php, which doesn't suck to work together with Redis as a database.

Goals & Design

I built this package out of frustrations of existing packages express-session, connect-redis, express-socket.io-session. This three doesn't work properly together with redis database. and We can't find the package that allows working with php.

So this simple package was designed to work with sessions using Redis as database and three of express + socket.io + php. You can use them all together or for each separately

Installation

$ npm install esr-php-session --save

Before usage important to know

For session works properly with php+socket.io+express you have to specify the same name in any initialization. This option esr_php_session_name: 'my_session', should be equal otherwise they can't work simultaneously and to know each other

Usage with express and socket.io

Include to file

var esr_php_session = require('esr-php-session');

in middlewire add this lines

For using with express

app.use(esr_php_session.express_session({
  esr_php_session_name: 'my_session',
  secret: 'my new secret',
  maxAge: (60 * 60 * 24), // by default 24 hours
  ex: 60,
}));

then you can put variables to res.esr_php_session something like res.esr_php_session = some_value and this value will saved and will available on next reload page.

For using with socket.io

io.use(esr_php_session.socket_io_session({
  esr_php_session_name: 'my_session',
  secret: 'my new secret',
  maxAge: (60 * 60 * 24), // by default 24 hours
  ex: 60,
}));

now for you available socket.esr_php_session and you can put there some variable like socket.esr_php_session.views = 30

Usage with php

at first find file /node_modules/esr-php-session/Esr_php_session.php and include it to your php project

require_once 'Esr_php_session.php';

then create an object

$obj = new Esr_php_session(array(
  'esr_php_session_name' => 'my_session',
  'secret' => 'my new secret',
  'maxAge' => (60 * 60 * 24), // by default 24 hours
  'ex' => 60,
));

that's it, when you create an object in this time will be automatically added to $_COOKIE a new element with name of your session $_COOKIE[esr_php_session_name]

Example with express

const express = require('express');
const esr_php_session = require('esr_php_session');
var app = express();
app.listen(3000);

app.use(esr_php_session.express_session({
  esr_php_session_name: 'my_session',
  secret: 'my new secret',
  maxAge: (60 * 60 * 24), // by default 24 hours
  ex: 60,
}));

app.get('/', function(req, res){
  console.log(req.esr_php_session.views);
  if(req.esr_php_session.views || req.esr_php_session.views == 0){
    req.esr_php_session.views++;
  }else{
    req.esr_php_session.views = 0;
  }
  console.log('req.esr_php_session.views = ', req.esr_php_session.views);
  res.send('Views = ' + req.esr_php_session.views);
});

Example with socket.io

...
io.use(esr_php_session.socket_io_session({
  esr_php_session_name: 'my_session',
  secret: 'my new secret',
  maxAge: (60 * 60 * 24), // by default 24 hours
  ex: 60,
}));

io.on('connection', function(socket){

  console.log('connected socket.id = ' + socket.id);

  if(socket.esr_php_session){
    if(socket.esr_php_session.views){
      socket.emit('message', socket.esr_php_session.views);
    }else{
      socket.esr_php_session.views = 0;
      socket.emit('message', socket.esr_php_session.views);
    }
  }
  console.log(socket.esr_php_session.views);
}
