This lesson

This lesson teaches Progressive framework: the concepts, APIs, and habits you need before advancing in Vue.

Vue’s progressive adoption lets teams add interactivity to one page without rewriting the whole app.

You will apply Progressive framework in contexts like: Greenfield SPAs, dashboards, design systems, and full-stack apps that pair Vue with PHP or Node APIs.

Write TypeScript, click Run—Vue 3 loads from CDN with the template compiler, mountApp shows UI in #app, and printOutput feeds the terminal.

At the start of the track—complete before JSX-heavy lessons that assume you understand the playground.

Progressive means you can start small—a single widget on a legacy PHP page—and grow into a full single-page application without a rewrite day one.

Levels of adoption

Script tag + CDN — enhance one section (this playground uses the same idea)
Build step with Vite — Single File Components (.vue), hot reload, TypeScript
Full SPA — Vue Router, Pinia for state, API layer, testing
Meta-frameworks — Nuxt for SSR, file-based routing, and deployment patterns

Why teams like progressive adoption

Ship a dashboard widget before committing the whole frontend
Keep server-rendered pages for SEO while Vue handles interactive islands
Migrate feature-by-feature instead of big-bang rewrites

Compared to React’s ecosystem

React is often described as a library—you choose router and data layers explicitly. Vue ships more built-in guidance (templates, reactivity, official router and state libraries) while still allowing escape hatches. Neither is universally “better”; match team skills and migration constraints.

Important interview questions and answers

Q: Can Vue coexist with server-rendered HTML?
A: Yes—mount on a #app node inside otherwise static pages, similar to React roots.
Q: When would you skip a full SPA?
A: Marketing pages, lightly interactive forms, or gradual migration where bundle size and complexity should stay minimal.
