Emotion is a performant and flexible CSS-in-JS library. Building on many other CSS-in-JS libraries, it allows you to style apps quickly with string or object styles. It has predictable composition to avoid specificity issues with CSS. With source maps and labels, Emotion has a great developer experience and great performance with heavy caching in production.

This library complements the internationalized routing capabilities of Next.js by managing translations and providing them to components.

Next.js gives you the best developer experience with all the features you need for production: hybrid static & server rendering, TypeScript support, smart bundling, route pre-fetching, and more. No config needed.

React-Toastify allows you to add notifications to your app with ease.

A fully typesafe router with first-class search-param APIs and built-in caching, built for JS/TS

Framework-agnostic CSS-in-JS with support for server-side rendering, browser prefixing, and minimum CSS generation.
