In this mini series we are going to Design and Build a chat application using Socket.io. We will first discuss basic design concepts while exploring the design for this application in Sketch. We will then move on to laying out our application in HTML and CSS, and lastly, will add Javascript to complete the functionality. Along the way, we are going to use modern Web Development technologies and features such as Flexbox, CSS Variables, ES6 Arrow Functions, ES6 Map, Let and Const variables, Node.js, Express.js, and Socket.io. - View it on GitHub
