App Shell Pattern
A PWA architecture that separates the minimal UI skeleton (shell) from dynamic content — the shell is cached by the service worker and loads instantly, while content is fetched fresh on each visit.
2mo ago mobile intermediate
Offline-First Design 🧠 1
An architectural approach where applications are designed to work fully without a network connection by default, treating connectivity as an enhancement rather than a requirement.

Progressive Web App (PWA) 🧠 1
A web application that uses modern browser APIs to deliver app-like experiences — installable on the home screen, working offline, and receiving push notifications — without requiring an app store.

Push Notifications (Web) 🧠 1
Browser notifications delivered to users even when the web page is not open, implemented via the Push API and service workers — requiring explicit user permission and a server-side push service.

A CSS approach where layouts adapt to different screen sizes using fluid grids, flexible images, and media queries — one codebase that works across mobile, tablet, and desktop.

Service Worker 🧠 7
A JavaScript file that runs in the background separate from the web page, intercepting network requests to enable offline support, background sync, and push notification delivery.

App Shell Architecture PHP 7.0+
Caching the minimal HTML, CSS, and JS needed to display the UI skeleton on first load — so the shell renders instantly from cache while dynamic content loads from the network.

Mobile Web Performance
Optimising web applications for mobile constraints — slower CPUs, limited RAM, high-latency 4G/5G, and battery sensitivity require different optimisation priorities than desktop.

Offline-First Design ES2015 🧠 1
Designing applications to work without a network connection by default — storing data locally, syncing when online, and handling conflicts gracefully.

PWA Installation & Add to Homescreen HTML5 🧠 1
Progressive Web Apps can be installed to the home screen like native apps — requiring HTTPS, a Web App Manifest, and a Service Worker, plus meeting browser-specific installation criteria.
3mo ago mobile intermediate
Responsive Design Patterns CSS3
Layout patterns for adapting UI across screen sizes — fluid grids, the column drop pattern, layout shifter, mostly fluid, and off-canvas navigation.

Touch Events & Pointer Events ES2015
Handling touch input on mobile — the Pointer Events API unifies mouse, touch, and stylus into one event model, replacing the need for separate touch and mouse event handlers.
3mo ago mobile intermediate
Web Push Notifications PHP 7.0+ 🧠 1
Sending notifications to users even when the browser is closed — using the Push API, Service Worker, and Web Push Protocol with VAPID authentication.

Diagram: Progressive Web Apps (PWA) Progressive Web Apps (PWA) ES2015 🧠 1
Web applications that use service workers, a manifest, and HTTPS to provide app-like experiences — installable, offline-capable, and push notification-enabled.
