Overall, Next.js applications consistently achieve excellent scores on metrics like Time to First Byte, Lighthouse Performance, Total Blocking Time etc. Next.js gives you the toolkit to build incredibly fast web apps.

Getting Started with Next.js and its tooling

Next.js offers a robust toolchain out of the box to streamline development, building and deployment of your apps.

Next.js CLI

The create-next-app CLI tool bootstraps a new Next.js project with zero-configuration. It provides options for TypeScript, ESLint, etc.

Built-in Compiler

Next.js bundles Webpack behind the scenes using optimized default settings for seamless compilation and bundling.

Development Server

npm run dev spins up the Next.js dev server providing hot reloading as you develop your app.

Example of Next.js

Let’s see a simple example to illustrate Next.js in action. We’ll build a basic blog site with pages for Home, About and Blog Post.

First, we create a pages/index.js file that serves as the home page by default in Next.js. The exported React component defines the page UI.

export default function HomePage() {
  return <h1>Welcome to my Blog!</h1>; 
}

For the About page, we add a pages/about.js file, again exporting a React component:

export default function AboutPage() {
  return <h1>About Me</h1>;
}

Finally, we create pages/blog/[slug].js to generate dynamic blog post pages:

export default function BlogPost({ post }) {
  // Fetch post data using slug  
  return (
    <div>
      <h1>{post.title}</h1>
      {post.content}
    </div>
  );
}

Next.js will automatically handle routing and code splitting for these pages. We can easily build on this to create a complete blog!

State Management in Next.js

Next.js does not have a built-in state management solution. However, it integrates well with external state management libraries like Redux, MobX and Recoil.

Redux is the most commonly used library for managing state in Next.js apps. It provides a centralized store for state, and actions/reducers to manipulate state immutably. Next.js apps can integrate Redux in two ways:

• Using react-redux bindings to connect state and components.
• Using Redux Toolkit for a simplified Redux setup.

MobX provides an alternative observable-based state management using a more declarative approach. It automatically tracks state changes instead of needing explicit reducers. MobX can also integrate nicely with Next.js apps.

Recoil is a newer state management library that provides greater flexibility than Redux, using atoms and selectors. It has gaining adoption within the Next.js community.

So in summary, while Next.js does not dictate a specific state management solution, Redux, MobX and Recoil are great options to manage state for scalable apps. The flexibility allows choosing a library aligned with your preferences.

Under pages/index.vue we define the home page component:

<template>
  <h1>Welcome to my Blog!</h1>
</template>

For the about page, we create pages/about.vue:

<template>
  <h1>About Me</h1> 
</template>

Then we add a dynamic blog post page under pages/posts/_slug.vue:

<template>
  <div>
    <h1>{{ post.title }}</h1>
    <div>{{ post.content }}</div>
  </div>
</template>

<script>
export default {
  async asyncData({ params }) {
    // Fetch post data using `params.slug`
  }  
}  
</script>

Nuxt.js will automatically handle the routing and transitions between these pages. We can continue developing upon this foundation further.

State Management in Nuxt.js

Nuxt.js tightly integrates with Vuex for state management in Nuxt apps. Vuex is the official centralized state management library for Vue, similar to Redux.

However, Nuxt.js goes a step further and provides direct integration with Vuex modules right out of the box. The store directory contains your Vuex modules, and Nuxt auto-registers them without needing boilerplate code.

The components of Vuex like state, mutations, actions, getters etc. can be directly used across your Nuxt app seamlessly. Since Vuex itself integrates deeply with Vue, this makes state management very straightforward with Nuxt.

Nuxt.js handles the complexity of hooking up Vuex to your backend Nuxt server automatically. Things like server-side rendering work smoothly. The tight integration also ensures your Vuex state is preserved properly across page navigations.

While external state libraries like Redux can be used with Nuxt, Vuex integration gives the advantage of building on top of the official Vue state management solution designed specifically for Vue apps.
