How To Node - NodeJS Authentification et WebSocket, avec Node.JS, Express, et Socket.IO | naholyr.fr ATTENTION : certaines portions de code présentées ici sont valables pour Express 2.x et ne fonctionnent plus avec Express 3.x. Il s’agit principalement de la partie traitant du parsing de cookie, l’articles reste à 95% valable, mais vous trouverez les détails pour Express 3 dans cet article → Authentification WebSocket avec les sessions Express 3.x et Socket.IO La première fois qu’on utilise les websockets, on se dit que c’est compliqué (pas tant que ça en fait). Et puis un jour on aimerait bien sécuriser la connexion au socket, parce que la partie « temps réel » nécessite d’être authentifié, ou simplement parce qu’il faut un pré-requis (comme avoir donné son nom avant de pouvoir chatter) avant que l’écoute ne démarre réellement. La première idée qu’on a est de se trimballer des flags et d’activer/désactiver l’écoute de certains messages en fonction de ces flags (par exemple: tant que l’utilisateur n’a pas donné son nom, les évènements « message envoyé » sont ignorés). Sommaire: 1. 2. 3.

Heroku | Cloud Application Platform Express - guide Getting started With node installed (download), get your first application started by creating a directory somewhere on your machine: $ mkdir hello-world In this same directory you'll be defining the application "package", which are no different than any other node package. You'll need a package.json file in the directory, with express defined as a dependency. Now that you have a package.json file in this directory you can use npm(1) to install the dependencies, in this case just Express: $ npm install Once npm finishes you'll have a localized Express 3.x dependency in the . $ npm ls hello-world@0.0.1 /private/tmp └─┬ express@3.0.0beta7 ├── commander@0.6.1 ├─┬ connect@2.3.9 │ ├── bytes@0.1.0 │ ├── cookie@0.0.4 │ ├── crc@0.2.0 │ ├── formidable@1.0.11 │ └── qs@0.4.2 ├── cookie@0.0.3 ├── debug@0.7.0 ├── fresh@0.1.0 ├── methods@0.0.1 ├── mkdirp@0.3.3 ├── range-parser@0.0.4 ├─┬ response-send@0.0.1 │ └── crc@0.2.0 └─┬ send@0.0.3 └── mime@1.2.6 Now to create the application itself!

Docs #Installing $ npm install socket.io #Using with Node http server Server (app.js) Client (index.html) #Using with Express 3/4 #Using with the Express framework #Sending and receiving events Socket.IO allows you to emit and receive custom events. Server #Restricting yourself to a namespace If you have control over all the messages and events emitted for a particular application, using the default / namespace works. This has the benefit of multiplexing a single connection. <script> var chat = io.connect(' , news = io.connect(' chat.on('connect', function () { chat.emit('hi!') #Sending volatile messages Sometimes certain messages can be dropped. If a certain client is not ready to receive messages (because of network slowness or other issues, or because they’re connected through long polling and is in the middle of a request-response cycle), if they doesn’t receive ALL the tweets related to bieber your application won’t suffer. #Broadcasting messages

Amazon Web Services, Cloud Computing: Compute, Storage, Database Node Js + Express Js + Jade + Socket I/O + Sails Js | Sois Net ! Node.js is a server-side software system designed for writing scalable Internet applications, notably web servers. Programs are written on the server side in JavaScript, using event-driven, asynchronous I/O to minimize overhead and maximize scalability (source : wikipédia) Node.js est un système logiciel côté serveur conçu pour écrire des applications Internet évolutives, les serveurs Web, notamment. Les programmes sont écrits sur le côté serveur en JavaScript, en utilisant la programmation évènementielle, E / S asynchrone pour minimiser les temps d’attentes et optimiser l’évolutivité. Node JS est tout simplement un interpréteur de JavaScript côté serveur. Plus besoin d’apache ou nginx, le serveur web est écrit en Javascript/NodeJs.

By the end of this Tutorial, you will be able to develop and deploy Node.js Applications by yourself. What is Node.js Node.js is a framework to develop highly-scalable applications which can handle tens of thousands of simultaneous client connections efficiently. It is intended to build scalable network programs easily. Node.js is based on V8 JavaScript Engine. History At the European JSConf 2009, Ryan Dahl introduced a project he has been working on. The project received huge appreciation immediately after the demonstration and did not look back since then. Core concept Event Driven / Asynchronous over Thread based Node instead, uses event driven programming. No locks over Deadlocks Event loop as a language construct than a library
