Programming with Mosh・2 minutes read

The course on NexJS covers everything from basics to advanced concepts, focusing on building a full-stack app for issue tracking, and utilizing a cutting-edge stack with practical projects. It also covers the fundamentals of NexJS, setting up the development environment, different rendering methods, and styling options like Tailwind and Daisy UI for efficient development.

Insights

  • Next.js offers a comprehensive course covering basic to advanced concepts, focusing on building a full-stack production-grade app for issue tracking with a cutting-edge stack of tools like NexJS 13, Tailwind, and Prisma, guided by an experienced instructor.
  • Server-side rendering (SSR) in Next.js is more efficient than client-side rendering (CSR) as it prevents unnecessary bundle size growth, allows search engine bots to index pages, and ensures optimal performance by using a mix of server and client components, with components organized in specific folders for efficient development.

Efficient navigation with server-side rendering in Next.js

  • Client-side navigation reduces the number of requests by only downloading necessary content.
  • Server-side rendering (SSR) and client-side rendering (CSR) are two ways to render components, with SSR being more efficient.
  • SSR prevents unnecessary bundle size growth and resource-heavy client-side rendering.
  • Search engine bots can view and index pages rendered on the server, unlike client-side rendering.
  • Server components lack interactivity and cannot access browser APIs, unlike client components.
  • A mix of server and client components is often used in real-world applications for optimal performance.
  • In Next.js, components in the app folder are server components by default, ensuring efficient rendering.
  • The pages router in Next.js does not support server components, necessitating the use of the app router.
  • Components can be organized in the components folder, co-located with pages for efficient development.
  • Fetching data in server components eliminates the need for state and effect hooks, improving performance and reducing bundle size.

Next.js Configuration, Caching, Rendering, and Styling

  • Configuration parameters in Next.js can be set, like revalidate, which triggers a background job to fetch fresh data from the backend at specified intervals, such as every 10 seconds.
  • Caching in Next.js is implemented in the fetch function, not in third-party libraries like Axios, ensuring data is not cached.
  • Next.js offers performance optimization techniques like Static rendering or static site generation, where pages or components with static data are rendered once during application build for production.
  • Dynamic rendering, on the other hand, occurs at request time, with examples showing how timestamps change in development mode but remain static in production due to caching.
  • Disabling caching in Next.js prompts the system to render pages dynamically at request time rather than statically at build time.
  • Rendering in Next.js can occur on the client or server, with Static rendering happening at build time and Dynamic rendering at request time.
  • Styling in Next.js can be achieved through Global Styles, CSS modules, Tailwind, and Daisy UI, each serving specific purposes in styling applications.
  • Global styles in Next.js should be reserved for truly global styles, while CSS modules are used for component-specific styles to prevent clashes.
  • CSS modules in Next.js are scoped to components or pages, preventing style conflicts by generating unique class names during transformation.
  • Tailwind, a popular CSS framework, utilizes utility classes for styling, offering a wide range of classes for padding, margins, text, colors, and font thickness.

Efficient styling with Tailwind and Daisy UI

  • Tailwind allows styling applications directly in the component file, eliminating the need to switch between CSS and component files.
  • The separation of concerns principle is maintained as each React component acts as a module with its own reusable boundary.
  • Tailwind ensures that only the utility classes used in the markup are included in the final CSS bundle, simplifying cleanup when components are changed or deleted.
  • Daisy UI, a popular component library for Tailwind, offers various components like buttons, accordions, and cards, simplifying development.
  • Installation of Daisy UI involves adding it as a development dependency and configuring it in the Tailwind configuration file.
  • Applying themes in Daisy UI involves activating the desired theme in the configuration file and specifying it in the HTML element using a data attribute.
