express-session-synchronize-socket.io
express middleware session can be attach to
socket.iohave an synchronizer session and can dist session HTTP with micro-service
Installation
npm i express-session-synchronize-socket.io --save
yarn add express-session-synchronize-socket.io
usage:
server.js
const
exp = require('express')
,app = exp()
,server = require('http').Server( app )
,session = require('express-session-synchronize-socket.io')()
, io = require('socket.io')( server )
;
app
// ... you'r other middlewares
.use( session.express( /* default value session optional */ ) )
// ... you'r other middlewares
;
app.get('/' , (req,res) => {
const val = req.session.val ; // session HTTP access
if( !val.id ) {
req.session.val.id = Math.random() ; // define one key id for current session
// manual synchronize session with tcp store
req.session.synchronize( {
model: "http"
,target: "tcp"
} ) ;
}
console.log('from HTTP: ' , val.id ) ;

// ... you'r other middlewares
;
io.on('connect' , socket => {
const val = socket.session.val;
// 0.xxx... , after request on "/" , because HTTP controller have synchronize memory strore
console.log( 'from TCP: ' , val.id ) ;
} ) ;

access to HTTP session from default route
use you HTTP session with an micro-service
and easier build view render
with Reactjs , Angularjs , Emberjs or other framework/library Javascript
custom micro-service HTTP session
config middleware
// ... ,
session = require('express-session-synchronize-socket.io')(
null, // give null for not default route access session
true
)
// ... ,define your routes with express e.g :
// ... ,
app
.get('/get/session/avatar' , ( req , res ) => {
// return only avatar session
res.json( req.session.user.avatar || null ) ;
} )
.get('/get/session/username' , ( req , res ) => {
res.json( req.session.user.username || null )
} )
.get( '/get/session/create-at' , ( req , res ) => {
res.json( req.session.user.createAt ) ;
} )
.get('/get/session/all' , ( req , res ) => {
// all is only user here
res.json( req.session.user ) ;
} )
;session HTTP is not save in cookies this package use local state of Nodejs for an memory store
you can thus easily imagine a structure using a notion of session server and client session the client session data being distributed in micro service for example where sent to your template in a more traditional way
