css-modules VS React

Use methodologies such as BEM, and technologies including CSS modules, CSS-in-JS, and Shadow DOM to isolate the styles of each micro-application and prevent conflicts, thus ensuring reliable encapsulation and modularity.

For many years, Culture Amp took the second option, and distributed shared components without compiled CSS. This meant that every app that consumed shared components needed to include the necessary CSS build tooling – at that time CSS Modules and node-sass – with a compatible version and configuration. This was relatively easy to set up, but over time proved difficult to maintain. When node-sass was deprecated in favour of (the much faster but slightly incompatible) Dart Sass, this demanded a difficult lock-step migration across all those codebases, which we have yet to achieve. And as new applications have switched to Tailwind for their own styles, they've had to continue to maintain those old build tools in parallel for the shared components' styles.

So CSS modules are a form of 3rd-party CSS-in-JS, where what you import are the class names, which are then usually obfuscated etc at compile time, and all the actual style declarations are (usually) compiled into a single css file or tag as part of the bundling process. You can read the og docs on'em here, and you've probably seen'em used in React like:

import styles from "./styles.css";

function Example(){
    return (
        

            Hello
        
    );
}

They predate the ability to import non-js files in vanilla by a good while, and rely on the compile process to translate your .css files into .js files that can be imported using whichever loader you use in your bundler.

Import assertions are a vanilla way to import non-js files by telling the browser how to import them; assert { type: "css" } says to treat the file as CSS and create a CSSStyleSheet, assert { type: "json" } says to treat the file as JSON and create a JSON object - and hopefully assert { type: "html" } will hopefully arrive soon and create a #document-fragment or something similar.

Hope that clears it up!

Extensions of CSS: for example, Sass, Less, Tailwind, CSS Modules, to make stuff look a certain way on your own.

The components are styled with CSS modules. When building the library, these styles will get transformed to normal CSS style sheets. This means that the consuming application will not even be required to support CSS modules. (In the future I want to extend this tutorial to use vanilla-extract instead.)

NextJS comes with built-in support for CSS Modules which allows you to scope your styles locally in individual components without worrying about name collisions or messing up other parts of the codebase.

CSS modules are not to be confused with mixins, as they serve the opposite purpose. While mixins are components or functions to be reused globally, modules are style sheets with a local scope used in a similar way as styled components in React.

CSS Modules CSS Modules is a pre-processing step: by default, styles are scoped locally to the current component, and the transpiler ensures no conflicts.

But if you don’t want to use any of those yet, I would suggest at least using CSS modules to scope styling to components.

Have you seen/tried CSS Modules? It's built into CRA and Vite, and it lets you write styles that are scoped to the component. I've heard people talk about using them alongside Tailwind, so I don't think it's necessarily an either/or situation, but to me it feels a lot more natural.

In the JavaScript ecosystem, there are guides for enabling SAML-based enterprise single sign-on in AdonisJS, Express.js, Next.js, Remix, and React with an Express.js backend.

What you have seen now works great especially when you are fetching data on the server, like in React Server Components using Next.js. But data fetching on the client side is often a bit more involved. At least what you want is for example some data loading indication and to know when the data is actually available in the client.

In addition to being a best practice, performance optimization in React is crucial since it affects the user experience directly. The speed and responsiveness of your React app are critical factors in determining its level of success in the modern digital world, where customers want seamless, quick, and uninterrupted experiences.

Familiarity with TypeScript, React and Next.js

We all know what React is at this point, but why use it with Vite and React Router DOM over something like NextJS?

Frameworks and Libraries: There are numerous JavaScript frameworks and libraries, such as React, Angular, and Vue.js, which simplify the development of complex web applications.

Javascript in the browser React - react is a library that gives developers an application programming interface (API) to manipulate the DOM (this is React's ReactDOM package). React uses components and JSX to make building reusable code easier. docs JSX - is a syntax extension for React Javascript code that lets you write HTML-like markup in a javascript file. This makes it easier to write reusable HTML. docs State - a key react concept that guides setting and storage of data between renders. docs Hooks - a key react concept for logic triggered by state change docs Vue - is a framework for building web interfaces. Vue is lightweight and best for small projects prioritizing speed over functionality. doc Angular - web development framework. Angular is best for dynamic more feature rich sites. docs
