Quick Facts about Next.js

Once Upon a Time: Next.js Takes the Stage

Imagine a band of JavaScript enthusiasts clamoring for a rockstar framework to bust the charts. Enter Next.js, born in a 2016 brainstorm by Guillermo Rauch and the zealous folks at Zeit (now Vercel), who were bent on harmonizing the chaotic world of SSR with the upbeat tunes of React. What's the fuss? Next.js let devs conjure web pages server-side, tickling the ivories of SEO and performance without breaking a sweat.


A Quantum Leap in Web Development: The 'getStaticProps' Razzle-Dazzle

Fast forward to the head-spinning tale of Next.js 9.3, dropping in March 2020. This version had devs grinning ear to ear with the debut act of 'getStaticProps' and 'getServerSideProps'. Static generation took a bow as Next.js juggled data-fetching like never before. Just like pulling a rabbit out of a hat, they made static and server-rendered pages frolic together seamlessly.



function HomePage({ props }) {
return 
{props.title}

}
// This gets called at build time
export async function getStaticProps() {
// Fetch data from an API
const title = await fetchMyTitle();
return {
props: {
title,
},
}
}


Next.js Goes Full Maverick: Incremental Static Regeneration

Let's jet to April 2020, following the trail of bread crumbs left by Next.js 9.5. Sneaky little thing called Incremental Static Regeneration (ISR) tiptoed onto the scene. Think of ISR as a cheeky chameleon—updates static content on the fly without the stage crew (your build process) breaking a sweat! This unsung hero works behind the curtains so your users get the freshest content without any hiccups.



export async function getStaticProps() {
return {
props: {...},
revalidate: 10, // In seconds
}
}

Top 10 Next.js Related Tech



JavaScript (The Programming Lingua Franca)

Let's cut straight to the chase – without JavaScript, you might as well pack up your Next.js dreams and go home. It's the very soil in which the framework's roots entangle; the bread to Next.js' butter. It's like the air for developers, but with more semicolons and fewer birds.



TypeScript (JavaScript's Smarty Pants Sibling)

TypeScript is JavaScript who went to college, got an education, and came back home insisting on type safety and clear documentation. Strongly-typed and smug about it, TypeScript adds that extra layer of sophistication, making your code as poised as a Victorian lady at tea time.


            
const greeting: string = "Hello, Next.js developer!";
            
        



React (The Soul of Next.js)

React is the heartthrob of modern web development – and Next.js is basically its cool, urban cousin. It's the Picasso of user interfaces, turning your clunky HTML into a masterpiece of stateful, responsive components that make users weep with joy (or frustration, depending on the bugs).



Node.js (The Silent Enabler)

Just like that rockstar roadie who sets up the stage for an epic concert, Node.js sets up the environment where Next.js can truly shine. It's the bouncer of the server party, dealing with requests, responses, and that tipsy module trying to sidestep npm's package management.



CSS-in-JS (Stylish, Literally)

Forget the vanilla CSS that wears socks with sandals. CSS-in-JS is like a fashion-forward trend that marries your styles with your components. It's the ultimate 'look good, feel good' for your code, ensuring that your interface dazzles users like a disco ball in a moonlit diner.



ESLint (The Code Whisperer)

No one truly appreciates a backseat driver until it's ESLint, telling you where you went wrong without screaming. It’s that wise sage perched upon your shoulder, making sure your JavaScript conforms to the etiquette of good coding standards. Ignore it at your peril or embrace it for harmonious coding zen.



Prettier (The Code Beautician)

Prettier is like the Marie Kondo of coding; it takes your messy code and, with a flick of its magic wand, transforms it into a work of art that actually sparks joy. If your code is a tousled hairdo, Prettier is the stylist that’s ready to do a makeover.



Webpack (The Packing Wizard)

Behind every successful code bundle, there’s a Webpack wizard, expertly orchestrating each module into neat, tidy parcels ready for deployment. It’s like a Tetris champion for your code, slotting every piece into the perfect spot for maximum performance and efficiency.



Redux/State Management (The Overseer)

Managing the state without Redux or similar state management libraries is like herding cats. Redux steps in like a wise old shepherd, giving every cat, I mean state, a place and keeping the chaos at bay with its mighty staff of actions and reducers.



API Routes (The Postman Always Rings Twice)

API routes in Next.js are your personal post office; they handle incoming requests and dispatch outgoing responses with the precision of a Swiss watch. If your data has places to be and APIs to see, these routes ensure everything arrives signed, sealed, and delivered.
