Props make components configurable. Slots make them extensible. Scoped slots give the consumer control over presentation while the component keeps the logic. Anyone who truly understands slots and scoped slots in Vue.js can build components that fit seamlessly into any context.

State explosion is the most common maintainability problem in growing Vue projects: components accumulate reactive variables, watchers, and local state until they become impossible to understand. The way out is to minimize state, derive state from props, and use reactivity only where it is actually needed.

A Vue Storefront is more than an SPA skeleton in front of the Magento API. Teams that separate rendering model, GraphQL data layer, caching and routing from day one build a storefront that stays fast at tens of thousands of products and can be extended without a rebuild.

Volar is the name of the VS Code extension, the underlying Vue Language Server is the actual language server backend that provides type checking, autocompletion and error diagnostics in single file components. Anyone who understands how the two layers work together fixes IDE problems in Vue 3 projects far more precisely, instead of installing and uninstalling extensions at random.

Vue provide/inject is the underrated middle ground between prop drilling and global Pinia stores. Used correctly, it enables scoped dependency injection for component families, type-safe, reactive and without global state.

Anyone using modern frontend stacks with PhpStorm loses time to missing autocomplete configuration, failed CSS class completion, and Vite processes that aren't integrated into the IDE. The right settings reduce context switching between terminal, browser and editor to a minimum.

Nuxt SEO goes far beyond title tags. useSeoMeta, correct canonical URLs, a complete Open Graph implementation and JSON-LD structured data together determine how well a Nuxt app is understood by search engines and displayed on social media.

Vue 3 reactivity is not magic, it is a precise system built from JavaScript Proxy, dependency tracking and scheduling. Anyone who understands how ref(), reactive(), computed() and watch() work internally stops making reactivity mistakes, picks the right tool for every use case, and knows immediately why a component is not re-rendering. This article explains the reactivity system fully and with practical examples.

Reactive programming is solved differently in every modern frontend framework, with incompatible APIs and abstractions hidden behind framework boundaries. The TC39 Signals proposal defines a universal foundation for the first time: Signal, computed, and effect as native JavaScript primitives that frameworks can build on.

Nuxt 3 with Nitro offers several caching layers that can be configured independently of each other: server-side Nitro cache, ISR with stale-while-revalidate, CDN cache-control headers and edge deployment. The right combination of these layers makes the difference between an application with an 800 ms TTFB and one with 40 ms.
