Building Progressive Web Apps (PWAs) with Modern APIs
Progressive Web Apps (PWAs) are web applications that leverage modern web technologies to deliver an app-like experience to users. They combine the best of web and mobile apps, offering features such as offline access, push notifications, and device hardware access. In this tutorial, we will explore how to build a PWA using modern web APIs, including Service Workers, Web App Manifest, and IndexedDB.
To follow along with this tutorial, you should have a basic understanding of HTML, CSS, and JavaScript. Familiarity with modern JavaScript (ES6+) is also helpful.
Building a Real-Time Chat Application with WebSockets in Node.js
WebSockets provide a full-duplex communication channel over a single TCP connection, allowing both the client and server to send messages at any time. Unlike HTTP, WebSockets maintain a persistent connection, making them ideal for applications requiring real-time updates, such as chat apps, online gaming, and live notifications.
If you haven’t already installed Node.js, you can download it from the official website. Node.js includes npm, the package manager we will use to install dependencies.
