Tutorials covering the frameworks and libraries that shape how modern applications are built — Angular, React, Vue, and the ecosystem tools that surround them. Each chapter is standalone, built around real examples and verified facts.
In the previous chapter, you set up Angular Universal and sent your first server-rendered page to the browser. The server produced HTML, the browser painted it immediately, and the user saw content before the JavaScript bundle finished downloading. That is the promise of SSR. But there is a second act that determines whether the promise…
A React application’s JavaScript bundle grows with every feature, every third-party library, and every route. The bundle that was 200 KB at the MVP stage becomes 2 MB after a year of additions, and the user who only wants to view their profile is downloading the admin dashboard, the rich text editor, and the entire…
A server-driven UI reverses the usual direction of a front-end build. Instead of shipping the markup and the styles from the client bundle, the server sends a description of the interface, and the client renders it. The description may be a JSON tree, a set of components, or a list of the Tailwind class strings….
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…
In the previous chapters, you set up Angular Universal for server-side rendering and learned how hydration makes the server-rendered HTML interactive. But SSR is not the only way to deliver pre-rendered HTML. When your content is the same for every user — marketing pages, blog posts, documentation, product catalogs with stable data — rendering on…
A loading state is not a spinner. It is a contract between the application and the user: the application has accepted the request, is working on it, and will show the result as soon as it is ready. The traditional way to implement this contract is a boolean flag—const [isLoading, setIsLoading] = useState(true)—checked at the…
A legacy application has years of CSS. The stylesheets are the thousands of lines, the selectors are the deep and the specific, the class names are the semantic (.btn-primary, .card-header), and the cascade depends on the load order that only the original author understood. The Tailwind adoption cannot be the big-bang rewrite; the application is…
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…
The Angular Router is one of the framework’s most used features and one of its least understood. You configure routes, navigate with routerLink, and read parameters from ActivatedRoute. That is the API surface most developers interact with. But underneath, the router is a state machine that runs through a specific sequence of events for every…
React’s rendering process is a synchronous, recursive operation. When a component throws during render, React cannot simply catch the error and continue—the component tree may be in an inconsistent state, with some components mounted and others not, some hooks already called and others not. In React 15 and earlier, this inconsistency would corrupt React’s internal…
