Vue’s reactivity model creates a specific challenge for end-to-end testing: the DOM changes after the test acts, not during. A click triggers a reactive state update, which schedules a re-render, which may trigger a router navigation, which may trigger an async data fetch, which may trigger another re-render. Tests that assert immediately after an action…
Storybook is a workshop for Vue components: each .stories.js file declares the discrete states a component can be in, and Storybook renders each state in isolation, outside the application. Visual regression testing exploits this structure. Every story is already a specification of what the component should look like in a given state. Capturing a screenshot…
VitePress and Nuxt both generate static HTML from Vue code, but they target different problems. VitePress is a documentation-first static site generator: Markdown files become pages, a default theme handles navigation and search, and the output is a content-centric site that ships almost no JavaScript beyond hydration . Nuxt is a full-stack Vue framework where…
Server-side rendering in Vue is not a framework feature that you enable with a flag. It is an architectural pattern that requires two coordinated entry points—one for the server and one for the client—and a renderer that converts a Vue application instance into an HTML string. The @vue/server-renderer package provides that renderer, and its API…
Hydration is the moment of truth for server-side rendering. The server sends HTML that the browser parses and displays, and then Vue’s client-side runtime walks that existing DOM, comparing it against the virtual DOM it would have produced from the same component tree. When the two match, Vue attaches event listeners and the page becomes…
Nuxt is the full-stack framework built on top of Vue. It takes the component model you already know and wraps it in a server engine, a routing system, and a data-fetching layer that work together without configuration. Where a plain Vue application requires you to assemble Vue Router, decide on a build tool, and wire…
Nuxt’s power comes not just from routing and data fetching, but from three interlocking systems that make the framework extensible, deployable, and ergonomic. Modules let you package and share framework modifications. The Nitro server engine compiles your server code into a standalone output that runs anywhere. Auto-imports eliminate the boilerplate of explicit imports while preserving…
Micro-frontends apply the principle of service decomposition to the browser. Instead of one monolithic Vue application, the UI is split into independently developed, tested, and deployed fragments that a shell application composes at runtime. Module Federation is the mechanism that makes this composition practical: it allows a JavaScript application to expose modules to other applications…
Internationalization is not a feature you add at the end of a project; it is a structural decision that touches every string, date, and number the user sees. vue-i18n is the standard library for this in Vue, and its modern Composition API mode changes how translation state flows through an application. Unlike a simple dictionary…
Headless components invert the traditional relationship between a UI library and its styling. Instead of shipping pre-styled components that you override with CSS, a headless library provides the behavior—state management, accessibility attributes, keyboard navigation, focus handling—and leaves every visual decision to you. Tailwind CSS is a natural fit for this model because it gives you…
