Next.js is a popular React framework that allows developers to build powerful and dynamic web applications with ease. It provides a number of features that make it a valuable tool for front-end development. In this tutorial, we will explore some of the most important Next.js features to learn.
1. Server-side rendering (SSR): One of the key features of Next.js is its support for server-side rendering. This means that the HTML for a page is generated on the server and sent to the client, rather than being generated in the browser. This can improve performance and SEO, as search engines can easily crawl the content of the page. To enable server-side rendering in Next.js, you simply need to export a function called getServerSideProps in your page component. This function will fetch data from an API or database and pass it to the component as props.
2. Static site generation (SSG): Next.js also supports static site generation, where the HTML for a page is generated at build time and served as a static file. This can improve performance even further, as there is no need to generate the page on each request. To enable static site generation in Next.js, you can use the getStaticProps function in your page component. This function will fetch data at build time and pass it to the component as props.
3. Automatic code splitting: Next.js automatically splits your code into smaller chunks, which are only loaded when needed. This can improve performance by reducing the initial load time of your application. You can take advantage of automatic code splitting by using dynamic imports for components that are not needed on the initial page load.
4. API routes: Next.js allows you to create API routes within your application, which can be used to fetch data or perform server-side operations. These routes are defined in a pages/api directory and can be accessed via a relative URL. This makes it easy to create a RESTful API within your Next.js application without the need for additional server configuration.
5. File-based routing: Next.js uses a file-based routing system, where each page of your application corresponds to a file in the pages directory. This makes it easy to create new pages and organize your project structure. You can also nest files within directories to create nested routes. For example, a file named about.js within a pages directory will create a route for /about in your application.
6. Image optimization: Next.js provides built-in support for optimizing images, which can improve performance by reducing the file size of images. You can use the next/image component to display images in your application, which will automatically optimize and serve the images in the appropriate format and size based on the device and screen resolution.
7. CSS and Sass support: Next.js has built-in support for styling your application with CSS and Sass. You can import CSS files directly into your components or use CSS modules for scoped styling. Next.js also supports global CSS stylesheets within the pages/_app.js file. If you prefer using Sass for styling, you can simply install the Sass package and import .scss files into your components.
8. TypeScript support: Next.js has excellent support for TypeScript, a popular statically typed language that helps catch errors early in development. You can easily set up a Next.js project with TypeScript by selecting the TypeScript option during project creation. This will generate TypeScript configuration files and allow you to write type-safe code throughout your application.
In conclusion, Next.js offers a wide range of powerful features that can help you build sophisticated web applications with ease. By mastering these key features, you can take full advantage of the capabilities of Next.js and create fast, performant, and maintainable applications. Happy coding!
Great video, huge benefit. Thank you.
Looks like we don't need tanstack's react-query anymore?
"Umm not sure i like the code. Just more stuff to learn wit hno much gain
This is very complicated to just be able to submit and get basic data
I am not going to watch anymore of your crap because you are going to fast and that is really stupid to teach like that. I hope you can get a clue.
You are going to fast. That is teaching ignorance.
That was the best intro ever 😂 thank you
I would pay a lot of money for like 50 – 100 videos like this. This is amazing man! I’ve been a C# and Django dev for a while, but I’ve been so impressed with NextJS and TypeScript. It’s such a powerful set of tools!
damm this video is almost perfect if wasn't for those clickity noisy keys 😭
Glad I found your channel. Thanks for the great content!
Can show the best way to handle loading when submiting data without useForm Hook. Do we use the tradional react way of defining a loading state and settting it to true and false before and after server action fn call.
the fact that I have to extract out buttons for pending hook to work is such a pain my god
I wish nextjs learned how to do page transition
Don't read the docs is the worst advice someone could give a developer.
what do you even eat bro
This one single video solved a lots of mysteries of myself, thanks a bunch
That keyboard sounds creamy af, mind showing us?
What's the name of the plugin which shows you error prompt next to the line where that error occured?
These concepts are mixed…
0:00 – Init and routing
1:03 – Data fetching via api routes
2:10 – Data storing via Server components
3:35 – form
6:26 – form status
These concepts are mixed so watch the short video to get full context / clarity…
