Drawing the Line: When to Use Server and Client Components in Your Next.js App

Cybermaxi7 — Wed, 20 Mar 2024 09:47:19 +0000

Introduction

Next.js is a powerful framework for building modern web applications. It excels at both server-side rendering (SSR) and client-side rendering (CSR), offering you the flexibility to optimize performance and user experience. Recently, Next.js introduced Server Components and Client Components, providing more granular control over your application's rendering strategy.

This blog post will guide you through understanding these components, their strengths, and when to leverage each one effectively in your Next.js projects.

Understanding Server and Client in Next.js

In web development, the server refers to the computer in a data center that stores your application code and responds to user requests. The client is the user's web browser that fetches content from the server and displays it to the user.

Next.js maintains two separate module graphs under the hood. One graph holds all the Server Components, which are rendered on the server. The other graph contains Client Components, which are initially rendered on the server but can leverage client-side JavaScript for interactivity.

Server Components in Next.js

Every component in Next.js is initially considered a Server Component by default. This means it's rendered on the server and sent to the browser as pre-rendered HTML. Server Components offer several advantages:

Improved SEO: Search engines can easily crawl and index the initial HTML content generated by the server.
Faster Initial Load: Users see the content instantly without waiting for JavaScript to download and execute.
Reduced Client-Side JavaScript: Less code running in the browser can lead to better performance.

Here's a simple example of a Server Component that displays a greeting message:

// server-component.js
export default function ServerComponent() {
  return (
    <h1>Hello from the Server!</h1>
  );
}

Client Components in Next.js

Client Components are ideal for situations where you need interactivity or complex UI elements that require client-side JavaScript manipulation.

To define a Client Component, we simply add the use client directive at the top of the file:



"use client"

// client-component.js
import { useState } from 'react'; // Import useState hook


export default function ClientComponent() {
  const [count, setCount] = useState(0);

  const handleClick = () => setCount(count + 1);

  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={handleClick}>Click me</button>
    </div>
  );
}

The use client directive indicates the start of a Client Component. These components are initially rendered on the server using placeholders, and then hydrated with actual content on the client-side using the RSC Payload.

Here's when Client Components are your best bet:

Interactive elements like forms, user input, and real-time updates.
Complex UI components that rely on heavy client-side JavaScript libraries.
Content that requires user-specific data or personalization.

The example above demonstrates how to use the useState hook in a Client Component. This hook allows us to manage the state of the component (the count variable) and update it using the setCount function triggered by the button click. This state management happens entirely on the client-side.

Interleaving Server and Client Components

The beauty of Next.js lies in its ability to combine Server Components and Client Components within your application. You can nest Server Components inside Client Components using the children prop. However, keep in mind that nested Server Components within Client Components will require additional data fetching on the client-side.

Conclusion

By understanding Server Components and Client Components in Next.js, you're equipped to make informed decisions about where to use each type in your application. This strategic approach leads to performant, SEO-friendly, and interactive user experiences.

The Advanced React Compound Component Pattern

Cybermaxi7 — Tue, 31 Oct 2023 14:53:46 +0000

Introduction

In the world of React development, the Advanced React Compound Component Pattern is a powerful concept that enables us to build parent components and their associated child components, which are designed to work seamlessly together. This pattern is a game-changer when it comes to creating highly flexible and reusable components with a truly expressive API, and it often requires little to no reliance on traditional props.

What is the Compound Component Pattern?

The Compound Component Pattern follows a simple principle: a set of components is meant to be used together within a parent component. Think of the HTML select element and its child option elements. The option elements only make sense when placed inside a select element, and they work together to create a dropdown menu. Compound components operate on the same principle, allowing us to design components that work harmoniously and provide a clean and expressive interface for developers.

Advantages of Using Compound Components

The Advanced React Compound Component Pattern offers several advantages:

Flexibility: By designing components that are tightly coupled, you gain flexibility in controlling the behavior of child components within the parent.
Reusability: Components created using this pattern are highly reusable and can be used in various parts of your application.
Expressive API: The API becomes expressive and intuitive, as child components are meant to be used in a specific way, reducing the need for excessive props.

Building a Counter App

To illustrate the power of the Advanced Compound Component Pattern, let's consider building a simple counter app using two different approaches: the traditional way and the advanced compound component pattern.

Traditional Approach

In the traditional approach, building a counter app might involve creating a parent component with various state management and rendering logic. Props are often used to control the behavior of the component. Below is a simplified example:

import { useState } from "react";
// Traditional Counter Component

import "./styles.css";
function Counter({ iconIncrease, iconDecrease, label }) {
    const [count, setCount] = useState(0);
    const increase = () => setCount((c) => c + 1);
    const decrease = () => setCount((c) => c - 1);
    return (
        <div style={{ display: "flex", gap: "10px", fontSize: "20px"}}>
            <label>{label}</label>
            <button onClick={decrease}>{iconDecrease}</button>
            <p>{count}</p>
            <button onClick={increase}>{iconIncrease}</button>
        </div>
    );
}
export default function App() {
    return (
        <div>
            <h1>Compound Component Pattern</h1>
            <Counter
                iconIncrease="+"
                iconDecrease="-"
                label="My NOT so flexible counter"
            />
        </div>
    );
}

While this approach works, it can become less manageable as the complexity of your component grows.

Advanced Compound Component Pattern

Now, let's explore the power of the Advanced React Compound Component Pattern using the context API by building the same counter app:

By utilizing the Compound Component Pattern, we've separated the display and behavior concerns into child components while maintaining a clean and expressive API.

Conclusion

The Advanced React Compound Component Pattern is a transformative approach for creating highly flexible and reusable components in React mostly. Its advantages include flexibility, reusability, and an expressive API. By harnessing this pattern, you can build components that work seamlessly together, enabling you to create cleaner, more maintainable code for your applications.

Redux vs. Context API: A Comprehensive Comparison

Cybermaxi7 — Sat, 07 Oct 2023 20:40:10 +0000

In the world of React state management, two popular choices stand out: the Context API and Redux. Each has its own set of advantages and trade-offs. In this article, we'll dive deep into their pros, cons, and recommendations on which one to use based on your project's needs.

1. Package Size and Setup:

Context API:

    // Context setup example
    import React, { createContext, useContext, useReducer } from 'react';

    // Create a context for your global state
    const MyContext = createContext();

    // Create a reducer function to handle state changes
    const reducer = (state, action) => {
      switch (action.type) {
        case 'UPDATE_VALUE':
          return { ...state, value: action.payload };
        default:
          return state;
      }
    };

    const MyProvider = ({ children }) => {
      const [state, dispatch] = useReducer(reducer, { value: '' });

      return (
        <MyContext.Provider value={{ state, dispatch }}>
          {children}
        </MyContext.Provider>
      );
    };

    export const useMyContext = () => {
      const context = useContext(MyContext);
      if (!context) {
        throw new Error('useMyContext must be used within a MyProvider');
      }
      return context;
    };

Redux:

    // Redux setup example
    import { configureStore, createSlice } from '@reduxjs/toolkit';

    // Create a slice with a reducer
    const mySlice = createSlice({
      name: 'mySlice',
      initialState: { value: '' },
      reducers: {
        updateValue: (state, action) => {
          state.value = action.payload;
        },
      },
    });

    // Create the Redux store
    const store = configureStore({
      reducer: mySlice.reducer,
    });

    // Dispatch an action to update state
    store.dispatch(mySlice.actions.updateValue('New Value'));

2. Handling Async Operations:

Context API:
Redux:

3. Performance Optimization:

Context API:
Redux:

4. Dev Tools:

Context API:
Redux:

Practical Recommendations:

While it's often said that the Context API is suitable for smaller apps and Redux for larger ones, the decision isn't always that straightforward. Let's delve deeper into when to use each:

Context API:
Redux:

Mastering useEffect: Rules, Best Practices, and Pitfalls

Cybermaxi7 — Sun, 24 Sep 2023 20:13:55 +0000

In the world of React, the useEffect hook is a powerful tool for handling side effects and managing component lifecycle. However, wielding this power comes with great responsibility. In this comprehensive guide, we'll delve into the rules, best practices, and common pitfalls when working with useEffect.

Dependency Array Rules

Inclusive Dependencies: The dependency array is your compass. Every state variable, prop, or context used inside the effect must find its place in this array. It ensures that your effect runs whenever any of these values change.
Reactivity Matters: Reactive values are the lifeblood of useEffect. Any function or variable that references another reactive value should be included. Don't forget, everything related to state, props, or context is a reactive value.
Dependency Is Not Optional: Dependencies choose themselves. Avoid ignoring the dependency ESLint rule; it helps you avoid unexpected behavior and bugs.
No Objects or Arrays: Objects and arrays should stay out of the dependency array. They're recreated on every render, and React considers a new object as different from the old one. ({} !== {})

Removing Unnecessary Dependencies

Function Dependencies: When it comes to functions, there are options:
- Move the function into the useEffect if it's used exclusively there.
- If the function is reused elsewhere, consider memoizing it using useCallback().
- If the function doesn't reference any reactive value, move it outside the effect for optimal performance.
Object Dependencies: Instead of including the entire object, focus on the specific property you need, especially if it's a primitive value. If that doesn't work, consider memoization techniques.

Other Strategies

Multiple Dependencies: When dealing with numerous reactive values, consider using useReducer to simplify your logic.
Stable Dependencies: No need to include setState (from useState) or dispatch (from useReducer) in the dependencies. React ensures their stability across renders.

When Not to Use useEffect

Last Resort: useEffect should be a last resort when no other solution makes sense. Consider alternatives first.

Cases of Overuse

Event Handling: Instead of using useEffect for responding to an event, create an event function. It keeps your code organized and readable.
Data Fetching: While fetching data when a component mounts might work in small apps, for real-world applications, consider using a library like react-query for better data management.
Synchronizing State Changes: Avoid using useEffect for synchronizing state changes with one another. Opt for derived state and event handlers for a cleaner and more maintainable codebase.

In conclusion, mastering useEffect involves understanding its rules, leveraging best practices, and recognizing when it's not the right tool for the job. By following these guidelines, you'll harness the true potential of useEffect in your React applications.

Mastering React State Management: From Local to Global

Cybermaxi7 — Fri, 15 Sep 2023 11:02:43 +0000

Welcome to the exciting world of state management in React! As developers, we know that handling state is a fundamental part of building robust web applications. In React, we have a multitude of options to manage state effectively, each tailored to different scenarios. Let's embark on a journey to explore these state management techniques and gain a deeper understanding of where and when to use them.

Understanding Types of State

To begin our journey, let's classify state based on accessibility and domain:

A. State Accessibility:

1. Local State: This type of state is specific to one or a few components and is accessible only to their child components.
2. Global State: Here, state is needed by multiple components, and it's accessible throughout the entire application.

B. State Domain:

3. Remote State: When all application data is loaded from a remote server (usually an API), it's considered remote state. This data is typically asynchronous and requires fetching and updating.

4. UI State: UI state encompasses everything else, such as themes, filters, form data, and more. These states are usually synchronous and are stored within the application.

State Placement Options

Now that we understand the types of state, let's explore where we can place them:

- Local Components: Use useState, useReducer, or useRef for managing state within a specific component.

- Parent Components: Lift state up to a parent component when needed. Utilize useState, useReducer, or useRef.

- Context: For global state, particularly UI state, leverage Context API combined with useState or useReducer.

- 3rd Party Library: If you require global state, consider using libraries like Redux, React-Query, SWR, Zustand, and others.

- URL: When you need to pass global state between pages, React-Router provides the tools you need.

- Browser: For storing data in the user's browser, use local storage or session storage.

Managing Different Types of State

Now, let's get practical. Here's how to manage different types of state in practice:

Local UI State: Use useState, useRef, or useReducer for handling local UI state within a component.

Local Remote State: In smaller applications, you can use fetch() combined with useEffect() and useState() or useReducer() to manage local remote state.

Global UI State: For global UI state, Context API combined with useState() or useReducer() is a powerful choice. You can also explore libraries like Redux, Zustand, Recoil, and even React-Router for navigation-based UI state.

Global Remote State: When dealing with global remote state, consider using Context API, fetch(), useEffect(), and useState() or useReducer(). Specialized tools like React-Query, SWR, and RTK Query can further streamline remote global state management.

This comprehensive guide equips you with the knowledge to choose the right state management approach for your React applications. Whether you're handling local UI state or managing global remote state, understanding these techniques will make you a more proficient React developer. 🚀🔗

Mastering State Management in React Router: Storing and Retrieving State in URLs

Cybermaxi7 — Wed, 13 Sep 2023 22:30:40 +0000

Today, I explored the fascinating realm of storing state in URLs using React Router. It's a game-changing concept that can enhance the usability and shareability of your web applications.

Why Store State in the URL? 🌐

The URL isn't just a path to your web pages; it's a versatile tool for managing UI state. Consider scenarios like toggling panels, sorting lists, or applying filters. Storing this information in the URL has compelling advantages:

Global Accessibility: State stored in the URL becomes globally accessible to all components within your app.
Data Persistence: Seamlessly pass data from one page to another, preserving the context effortlessly.
Bookmark and Share: Users can bookmark or share a page with its exact UI state, fostering collaboration.

Params and Query Strings in URLs 📊

When it comes to storing state in URLs, we rely on two key components: params and query strings. Let's dissect a URL to understand their role:

www.example.com/app/cities/lisbon?lat=38.2&lng=-9.4

app/cities: The path segment of the URL.
lisbon: Params, allowing for targeted data transmission.
lat=38.2&lng=-9.4: Query strings, perfect for global state management.

In React, we harness this power with the help of React Router's useParams().

Implementing State Storage with Dynamic Parameters 🛤️

Let's dive into some code to illustrate the concept further:

import React from 'react';
import { BrowserRouter as Router, Route, Link, useParams } from 'react-router-dom';

// Component for Page 1
function Page1() {
  // Access the "id" parameter from the URL
  const { id } = useParams();

  return (
    <div>
      <h2>Page 1</h2>
      <p>State stored in URL: {id}</p>
      <Link to="/page2">Go to Page 2</Link>
    </div>
  );
}

// Component for Page 2
function Page2() {
  return (
    <div>
      <h2>Page 2</h2>
      <Link to="/page1/123">Go to Page 1 with State</Link>
    </div>
  );
}

// App Component
function App() {
  return (
    <Router>
      <Route path="/page1/:id" component={Page1} />
      <Route path="/page2" component={Page2} />
    </Router>
  );
}

export default App;

In this example:

We define a dynamic route using :id in the route path ("/page1/:id"), allowing for state changes.
In the Page1 component, we access the id parameter from the URL using useParams().
You can visit "/page1/123" to see the state stored in the URL.
Links within the components navigate between pages and pass state in the URL.

By following these steps, you open a world of possibilities for your React applications.

Mastering React Styling: A Beginner's Guide

Cybermaxi7 — Tue, 12 Sep 2023 20:39:03 +0000

Styling is a crucial aspect of building visually appealing and user-friendly web applications. In the React ecosystem, developers have a plethora of styling options to choose from. But why are there so many options? The answer lies in React's flexibility and lack of a built-in styling solution. React gives developers the freedom to choose their preferred styling approach. Let's explore some of the common styling options in React, each with its own characteristics and use cases. 🎨

Why So Many Styling Options?
React is an opinionated library; it doesn't impose a specific styling approach. Instead, it grants developers the liberty to pick the method that resonates most with their project's needs. Let's delve into some of the common styling options in React, each with its own distinct characteristics and use cases. 🚀

1. Inline-CSS
✨
Where: JSX elements
How: style props
Scope: JSX elements
Based on: CSS
Inline-CSS offers simplicity in styling React components. You define styles directly within your JSX code using the style prop. It's convenient for quick styling but can become unwieldy for complex designs.

2. CSS or Sass Files
✨
Where: External files
How: className prop
Scope: Entire app
Based on: CSS
Using external CSS or Sass files allows you to maintain separate stylesheets for your React components. You apply styles using the className prop. This approach provides global styling across your entire application but may lead to class name conflicts.

3. CSS Modules
✨
Where: One external file per component
How: className prop
Scope: Component
Based on: CSS
CSS Modules offer a solution to class name collision issues. You create dedicated CSS files for each component and import them using module syntax. This approach encapsulates styles within each component, preventing unintended side effects.

4. CSS in JavaScript (Styled Components)
✨
Where: External file or component file
How: Creates new component
Scope: Component
Based on: JavaScript
Styled Components, a popular library, allows you to write CSS-in-JS. You create styled components as JavaScript functions. This approach offers component-level styling and leverages JavaScript's power to generate dynamic styles.

5. Utility-First CSS (e.g., Tailwind CSS)
✨
Where: JSX elements
How: className props
Scope: JSX elements
Based on: CSS

Utility-first CSS frameworks like Tailwind CSS provide a set of utility classes that you apply directly to JSX elements. This approach encourages rapid development by applying pre-defined styles using class names.

6. UI Libraries
✨
In addition to the traditional styling methods, React developers have the option to leverage UI libraries such as Material-UI (MUI), Chakra UI, Mantine, and many more. These libraries offer pre-designed components with consistent styling and extensive customization options, simplifying the styling process and enhancing the development experience.

In conclusion, the diverse landscape of styling options in React caters to various preferences and project requirements. Whether you gravitate toward the simplicity of inline styles or harness the power of CSS-in-JS, React provides the flexibility to choose the styling approach that best suits your specific needs. Exploring these options empowers you to craft beautiful and functional React applications that captivate users and make your coding journey an exciting one. Happy styling! 🎉🎨

Functional and Class Component in React.js: Exploring React's Evolution

Cybermaxi7 — Thu, 31 Aug 2023 20:19:54 +0000

In the world of React development, there's an ongoing debate about the choice between Class Components and Functional Components. Each has its own advantages and use cases. In this article, we'll delve into the key differences between these two approaches and shed light on which one might be more suitable for your projects.

Evolution of Components
Functional Component: A modern approach that gained prominence with the introduction of hooks in React 16.8 (released in 2019). It's important to note that function components existed even before hooks (pre-React 16.8), but their capabilities were limited without the ability to manage state.

Class Component: The older approach, dating back to React 0.13 in 2015. Class components have been a staple in React development for a long time and are still used in various codebases.

Note: React's function components existed before hooks, but they lacked certain features like local state management.

Creating Components
In React, creating components is the foundation of building UIs. Let's compare how Class Components and Functional Components are created:

Functional Component: These are created using standard JavaScript functions. This can be a function declaration or an arrow function.

const FunctionalComponent = (props) => {
  // Component logic here
};

Class Component: Class components are built using ES6 classes that extend the React.Component class.

class ClassComponent extends React.Component {
  // Component logic here
}

Handling Props and State
Props and state are essential aspects of React components. Let's see how they are managed in both Class and Functional Components:

Class Component: In class components, props are accessed using this.props.X, and local state is managed using this.setState.
Functional Component: Functional components simplify this process. Props can be accessed using destructuring, like { X } = props. Local state is managed using the useState hook.

Managing Side Effects and Lifecycle
One of the most significant differences between Class and Functional Components is how they handle side effects and component lifecycle.

Class Component: React's class components rely on lifecycle methods such as componentDidMount and componentWillUnmount for managing side effects and synchronization.
Functional Component: In functional components, the focus is on synchronization rather than a traditional lifecycle. This is achieved using the useEffect hook, which provides a more intuitive and streamlined way to manage side effects.

Event Handling and JSX Return
Functional Component:
In a functional component, event handlers can be defined as regular functions within the component's body. JSX is returned directly from the function.

import React from 'react';

const FunctionalComponent = () => {
  const handleClick = () => {
    console.log('Button clicked in functional component');
  };

  return (
    <div>
      <button onClick={handleClick}>Click me (Functional)</button>
    </div>
  );
};

export default FunctionalComponent;

Class Component:
In a class component, you need to define separate methods for each event handler. JSX is returned from the render method.

import React from 'react';

class ClassComponent extends React.Component {
  handleClick() {
    console.log('Button clicked in class component');
  }

  render() {
    return (
      <div>
        <button onClick={this.handleClick}>Click me (Class)</button>
      </div>
    );
  }
}

export default ClassComponent;

Managing Side Effects and Lifecycle
Functional Component:
In functional components, you can use the useEffect hook to handle side effects and synchronization, similar to how you would use lifecycle methods in class components.

import React, { useEffect } from 'react';

const FunctionalComponent = () => {
  useEffect(() => {
    console.log('Functional component mounted');
    return () => {
      console.log('Functional component unmounted');
    };
  }, []);

  return <div>Functional Component</div>;
};

export default FunctionalComponent;

Class Component:
In class components, lifecycle methods like componentDidMount and componentWillUnmount are used to manage side effects and synchronization.

import React from 'react';

class ClassComponent extends React.Component {
  componentDidMount() {
    console.log('Class component mounted');
  }

  componentWillUnmount() {
    console.log('Class component unmounted');
  }

  render() {
    return <div>Class Component</div>;
  }
}

export default ClassComponent;

Advantages of Functional Components
Functional components offer several advantages over class components:

Ease of Development: Functional components require less boilerplate code, making them quicker to develop.
Cleaner Code: The useEffect hook consolidates all lifecycle-related code, resulting in cleaner and more organized code.
Custom Hooks: Functional components, in conjunction with custom hooks, facilitate the sharing of strategic logic across components.
No More this: Functional components eliminate the need for using the this keyword.

The Class Component's Edge
While functional components have gained dominance, class components still hold an advantage in terms of beginner-friendliness due to their more straightforward lifecycle methods, such as componentDidMount and componentWillUnmount.

Understanding React Hooks: A Deep Dive

Cybermaxi7 — Mon, 28 Aug 2023 20:27:39 +0000

React hooks have become an essential part of modern React development, providing a powerful way to interact with React's internal mechanisms. In this article, we'll explore what React hooks are, how they work, and why they've revolutionized the way we build React applications.

What Are React Hooks?

At their core, React hooks are specialized functions built into React that grant us direct access to its internal operations. Think of hooks as an API that allows us to tap into React's inner workings—like creating and accessing state within the fiber tree or managing side effects effectively.

Hooks empower us to perform tasks such as manual DOM selections and more. They also introduce a unified naming convention—notice the common "use" prefix in hook names like useState and useEffect. This consistency enables us to encapsulate and reuse non-visual logic seamlessly.

The Power of Hooks

One significant advantage of hooks is their ability to give function components state ownership and the capability to manage side effects at various lifecycle points. This functionality was previously exclusive to class components before React v16.8 introduced hooks.

Exploring Common Hooks

useState: Easily manage state within functional components.
useEffect: Handle side effects and lifecycle events efficiently.
useReducer: Alternative state management solution for more complex scenarios.
useContext: Access context values without nesting components.

Unveiling Lesser-Known Hooks

While some hooks take the spotlight, there's a treasure trove of lesser-known hooks waiting to be discovered. Some of these include useRef, useCallback, useMemo, useTransition, and more. These hooks provide specialized functionalities for various use cases, from optimizing performance to managing references.

Navigating Hook Usage: Rules to Remember

Location Matters: Hooks must be called at the top level of a functional component. Avoid using them within conditionals, loops, nested functions, or after an early return. This rule ensures hooks maintain a consistent order—critical for their proper functioning.
Contextual Calling: Hooks can exclusively be used within React functions, meaning they're suitable for both function components and custom hooks. If you're using React's ESLint, it automatically enforces this rule, highlighting any violations.

In Conclusion

React hooks have transformed the way we approach React development, offering a clean and effective way to manage state, side effects, and more within functional components. By understanding their nuances and following the rules of usage, you'll unlock the true potential of React hooks in your projects.

Unveiling the Distinction: Frameworks vs. Libraries and Navigating React's Abundant Ecosystem

Cybermaxi7 — Sun, 20 Aug 2023 20:15:14 +0000

I noticed misconceptions about frameworks and libraries, so I'll try to explain the differences. 🔍

Note: REACT IS A LIBRARY AND NOT A FRAMEWORK!!! 🚫📦

What are Frameworks?

In the world of JavaScript, a framework (an all-in-one kit) is a complete structure that includes everything you need in order to build a large-scale application. It encompasses everything (like HTTP requests, Styling, Routing, Form Management, etc.) all out of the box.

However, the downside is that you're bound by the framework's tools and conventions (which is not always bad). Examples of Frameworks include Svelte, Vue, Angular, etc.

What are Libraries?

Basically, libraries are pieces of code that developers share with other developers to use. A good example is React, which we call a view library because all it does is draw components onto the user interface (UI).

However, if you want to build a large-scale single-page application, you'll need to include a lot of external libraries for things like HTTP requests, Styling, Routing, Form Management, etc.

Using a library gives you freedom; you can choose multiple 3rd-party libraries to build a complete application. The downside is that you need to research, download, learn, and stay up to date with multiple external libraries. 📚🕵️‍♂️

REACT'S 3RD PARTY LIBRARY ECOSYSTEM

Due to React's immense popularity, it has led to a vast ecosystem of libraries that we can include in our projects for various needs, such as:

Routing (for single-page applications SPA):

React Router
React Location etc.

Making HTTP Requests:

Fetch()
Axios etc.

Managing Remote Server State:

React Query
Apollo Client etc.
SWR (Stale-While-Revalidate) etc.

Global State Management:

Context API
Redux
Zustand etc.

Styling:

CSS Modules
Styled Components
Tailwind CSS etc.

Form Management:

React Hook Form
Formik etc.

Animations/Transitions:

Motion
React Spring

Entire UI Components:

Material UI
Chakra UI
Mantine

Due to the numerous library options for React application needs, developers saw a need to create frameworks on top of React, which include:

Next.js
Remix
Gatsby

These are opinionated React frameworks. They offer many features such as server-side rendering (SSR), static state generation (SSG), and a better developer experience, among others. 🛠️🚀

React UI Component Splitting Demystified: The Ultimate Guide to Building Better UIs

Cybermaxi7 — Sun, 13 Aug 2023 19:58:48 +0000

In React, we often encounter the challenge of splitting the User Interface (UI) into components. The size of a component matters significantly, and finding the right balance is crucial; we want to avoid going too small or too big.

IF A COMPONENT IS TOO SMALL 🤏

We end up with hundreds of tiny components. 😩
This leads to a confusing codebase, making it difficult to understand and navigate complex and disorganized source code in software development. 🕵️‍♂️
Everything becomes overly abstracted, a process that simplifies complex concepts by focusing on essential details and hiding unnecessary complexities. 🧩

IF A COMPONENT IS TOO BIG 💥

It takes on too many responsibilities. 🧱
Requires an excessive number of props. 🪚
Becomes challenging to reuse. ♻️
Leads to complex code that's hard to understand. 🤯

HOW TO SPLIT A UI INTO COMPONENTS

We've established four fundamental criteria for splitting UI into components, which involve asking yourself the following questions:

1. LOGICAL SEPARATION OF CONTENT/LAYOUT

Does the component contain pieces of content or layout that don't naturally belong together? For instance, both the navbar and the sidebar have their unique purposes, yet together they contribute to overall navigation and content organization. 🧭

2. REUSABILITY

Is there a genuine potential for reusing a part of the component? 🔄
Do you want or need to reuse it? 🔄

3. RESPONSIBILITY / COMPLEXITY

Is the component attempting to do too many things at once? 🤹‍♂️
Is it reliant on an excessive number of props? 📦
Does the component incorporate numerous pieces of state and/or effects? ⚡️
Is the JSX code within the component overly complex and confusing? 😵‍💫

4. PERSONAL CODING STYLE

Do you lean towards smaller or larger functions/components? Here, I'd advise creating components in a manner that enhances your productivity. ⚖️

NOTE
When unsure, start with relatively larger components and then split them into smaller ones as needed. 🛠️
In light of this, here are some general guidelines:

Remember that creating a new component introduces a new level of abstraction. Keep in mind that more abstraction comes with a cost as it demands more mental effort to switch between components. Hence, avoid creating new components prematurely. 🧠
Name a component based on its functionality and display. Don't shy away from using descriptive component names, even if they're lengthy. 🏷️
Avoid declaring a new component within another one. Instead, for related components, consider the approach in point 4 below. 🚫➡️➡️
Place related components in the same file (co-locate). Don't separate components into different files too hastily. 📁
Understand that it's entirely normal for an application to comprise components of varying sizes, ranging from small to large. 📐

In conclusion, keep these considerations in mind. Strive to avoid incorporating overly extensive functionalities into a single component, and make an effort to merge functionalities into fewer components when possible, always keeping reusability in mind. 🤝
