Socket.io makes use of Engine.io to achieve server-side connection with Engine.io-client for the client side.ĭata transfer in Socket.io is mostly done in the form of a JSON (JavaScript Object Notation), so we will be using the JSON format for this article. Each connection, also known as a socket, consists of two parts: The server side and the client side. Data transfer is done via an open connection allowing for real-time data exchange. Socket.io is a JavaScript library that works similarly to WebSockets. Socket connections can be a server to the client, client to server, or between two clients or servers. A connection in a socket persists once created until it is terminated. Sockets are connections achieved between given points in a network. WebSockets can be used to build out anything from a real-time trading application to a chat application, or just about anything that requires efficient, real-time data transfer. Unlike the HTTPS protocol, WebSocket allows for data transfer in both directions. This connection persists until the channel is terminated. WebSocket is a web communication protocol that allows for the transfer of data from the client side to the server side (and from the server side to the client side) once a channel between them is created. This article covers the basics of Socket.io, from setting up a connection to connecting your client side to the server side. You should know that Socket.io is not a WebSocket, but rather a custom real-time transfer protocol implementation built on other real-time protocols. It consists of both the client side and the server side, with the server side handling different connections and information dispersion. Whether you are building a chat application, a video sharing app, or even a video conferencing app, Socket.io provides a connection between your clients, allowing for lightning speed data transfer between them. So, it is just like a real-time web-page opened in multiple clients’ browser which are connected to a common server, i.e, localhost.Ī complete documentation for using express module.Ī complete documentation for using nodemon module.Elizabeth Amaechi Follow Web developer and technical writer.

We can open this page in as many windows as we want. Now, we’ll open the browser and enter in the address bar.

The following message will be displayed in the console - Server listening on port: 3000 Now, we can start our server in the terminal using the command npm run start. Step 4 - So, our coding part is complete. It will also emit events which will be received by the client for proper functioning of our web application. It will receive all the events emitted by the client and will properly handle them. Our server application will send index.html file to the client. The style.css file will contain the following codes. Now that we have understood the function of our html file, let’s write the CSS file so that our webpage looks good. babelrc which will be opened in a text editor and the following text will be entered - ) Then, in our project directory, we’ll create a file named. So, the beginning of our package.json file should look like the following. Then, we’ll open the package.json file in a text editor and add the following value corresponding to the key ‘script’.

Npm install -save-dev babel-cli babel-preset-env babel-preset-stage-0Ībove command will install babel-cli, babel-preset-env and babel-preset-stage-0 modules which are the dev dependencies of our project. This will install express, nodemon and socket.io modules which are the dependencies of our project. Npm install -save express nodemon socket.io Then you have to run following commands.

Then you will be asked to enter various details about your application, which will be stored as a json file named ‘Package.json’. Navigate into that directory and run npm init. Step 1: First of all, open the terminal and create one directory which will be dedicated for our project. So, now we are ready to initiate our project. Node.js should be installed on your local machine.Knowledge of - HTML, CSS, JavaScript, JQuery, and Node.js.
