Today's mission...

Thursday 22nd February 2024

With all the designing I did, I'm too excited to wait into I have most of the pages done to code something so I decided to take just a small piece from one of the designs I did and just work on it!

I chose the (I don't even know what to call it) fanfic information card + the popup options menu to the side. I want to test myself to work on the popup menu's functionality because I already know I can replicate the design to the tip - not to toot my own horn thought...!

The target is to get it done by today!

React JS

Component-Based Architecture:

React applications are built using components, which are reusable, self-contained pieces of the UI. Components can be nested, managed, and handled independently, leading to better maintainability and scalability.

JSX (JavaScript XML):

React uses JSX, a syntax extension that allows HTML to be written within JavaScript. This makes the code more readable and easier to write.

Virtual DOM:

React maintains a virtual DOM, an in-memory representation of the actual DOM. When the state of an object changes, React updates the virtual DOM and efficiently determines the minimal set of changes needed to update the real DOM, leading to performance improvements.

One-Way Data Binding:

Data flows in one direction, from parent to child components, which makes the data flow and logic easier to understand and debug.

State Management:

React components can maintain internal state, making it easy to build dynamic and interactive UIs. For more complex state management, libraries like Redux or Context API can be used.

Advantages of Using React

Performance:

Due to the virtual DOM, React minimizes direct manipulation of the DOM, resulting in better performance for dynamic applications.

Reusable Components:

Components can be reused across different parts of an application, reducing the amount of code and enhancing consistency.

Strong Community and Ecosystem:

A large community and a rich ecosystem of tools and libraries support React, making it easier to find solutions, get support, and integrate with other technologies.

SEO Friendly:

React can be rendered on the server using Node.js, making web pages more SEO-friendly compared to traditional client-side rendering.

Getting Started with React

To start building applications with React, you need to have Node.js and npm (Node Package Manager) installed. Here’s a basic setup to create a new React application:

Install Node.js and npm:

Download and install from Node.js website.

Create a New React Application:

You can use Create React App, an officially supported way to create single-page React applications with no configuration required:

npx create-react-app my-app cd my-app npm start

import React from 'react';

function Welcome(props) { return

Hello, {props.name}

; }

export default Welcome;

Introduction to React JS 

React is like the carpenter’s toolbox for building web interfaces. Created by the folks at Facebook, it’s a set of tools that makes crafting interactive and dynamic websites a whole lot easier. Imagine it as a set of magic building blocks that help developers create sleek, responsive, and engaging front-end applications. Since its debut in 2013, React has become a favorite among web developers, kind of like the go-to tool when you want to make your website not just look good but also feel lively and interactive. It’s a bit like the secret sauce behind many of the awesome websites you use every day.

Features of React JS

Declarative Syntax: React uses a declarative syntax, allowing developers to describe the desired outcome, and React takes care of the underlying logic to achieve that outcome. This makes the code more predictable and easier to understand.

2. Component-Based Architecture: React follows a component-based architecture where the UI is broken down into reusable components. Each component manages its own state and can be composed to build complex user interfaces.

3. Virtual DOM: React uses a virtual DOM to improve performance. Instead of directly manipulating the actual DOM, React creates a virtual representation of it in memory and updates only the parts of the actual DOM that have changed. This minimizes the number of DOM manipulations, resulting in faster updates.

4. JSX (JavaScript XML): React uses JSX, a syntax extension for JavaScript that allows you to write HTML elements and components in a syntax similar to XML or HTML. JSX makes the code more readable and helps with the integration of UI components.

Components in React

In React, think of components as building blocks for your user interface — they’re like Lego pieces that you can assemble to create your application. These components are self-contained and can be reused, making it easier to manage and organize your user interface. It’s as if you’re constructing your application with Lego bricks, where each brick represents a specific part of your user interface.

This modular approach simplifies the development process and encourages a more flexible and maintainable code structure.

Dumb components: Think of these components as the friendly faces you see in a store’s display window. They’re there to catch your eye and make everything look inviting. These components are all about the visual appeal, like the welcoming decor of a shop, without getting into the technical details or behind-the-scenes work.

2. Smart components:Think of these components as the wise decision-makers. They not only handle the important business details but also decide when and how things should appear on the screen. It’s like having an event planner for your app — they manage the behind-the-scenes work and ensure everything shows up at just the right time and in the best way possible.

NOTE 🤓:These components can come to life either as classes or functions. They’re adaptable, like a versatile tool that can be crafted in different ways based on your needs.

State of a component

In the world of React, think of the state as a component’s personal notebook — it’s where the component keeps track of information that can change over time. This information might shift based on how users interact with the component or how the outside world reacts to it. Whether the component is a classic novel (a class) or a snappy note (a function), it handles its state in its own unique way. What’s really neat is that when this internal state undergoes a change, it’s like the component automatically freshens up, updating its look without any fuss — kind of like a quick, seamless makeover happening in the background.

Properties of a component

In React, components communicate with each other through a feature called “Props.” It’s like sharing notes or gifts between them, but here’s the catch: the communication is a one-way street, flowing strictly from a parent component to its child. Imagine it as a parent passing a sealed letter to their child. What’s interesting is that these messages, or props, are unchangeable once delivered. It’s akin to sending a secure package — the information remains intact, ensuring a clear and organized flow of data between React components.

Life cycle of a component

Components in React have a lifecycle, and it’s like understanding the natural flow of a component’s journey. This lifecycle serves as our guide, allowing us to make smart decisions at different points in the component’s existence. It’s a bit like knowing when to take specific actions, such as making an HTTP request or tidying up the user interface.

componentDidMount: Think of this as the behind-the-scenes moment when the component takes its place on the UI stage for the first time.

componentDidUpdate:Picture this as the component’s way of adapting and evolving — a sort of behind-the-scenes dance that happens when the component experiences a change in its mood or receives something new to work with.

componentWillUnmount: Function executed when the component is unmounted from the UI.

React Hooks are a set of functions that were introduced in React 16.8 to enable the use of state and other React features in functional components. Before the introduction of hooks, state and lifecycle methods were primarily associated with class components. Hooks allow functional components to have state, lifecycle features, and more, making them a powerful and concise alternative to class components.

The most commonly used React Hooks include:

use State: Enables functional components to manage state.

2. use Effect: Provides a way to perform side effects in functional components, similar to component DidMount and component DidUpdate in class components.

3. use Context: Allows functional components to subscribe to React context without introducing a nested component.

4. use Reducer: An alternative to use State for managing more complex state logic in functional components.

5. use Callback and use Memo: Optimize performance by memoizing functions and values to prevent unnecessary re-renders.

Hello world with create react app

Create React App is a ready-to-go setup designed for building React applications. It works seamlessly with Node version 14.0.0 or higher and npm version 5.6 or higher. To kickstart a new project, simply run the following commands in your terminal:

“npx create-react-app your-project-name”

Most used add-on libraries in React JS

1. Redux: A predictable state container for managing the state of your application in a more organized and scalable way.

2. React Router: Provides navigation and routing functionalities for React applications, allowing you to create dynamic and SPA (Single Page Application) experiences.

3. Axios: A promise-based HTTP client that simplifies making HTTP requests in React applications.

4. Styled-components: Enables writing CSS directly in your JavaScript files using tagged template literals, promoting component-based styling.

Most Common React JS Web Development Mistakes & How to Fix Them

React JS has become a popular choice for web development due to its flexibility, performance, and component-based architecture. However, many developers, especially beginners, often make mistakes that can impact the efficiency and maintainability of their applications. In this blog, we will explore some of the most common React JS web development mistakes and how to fix them.

1. Not Using Functional Components and Hooks

The Mistake:

Many developers still rely on class components when functional components combined with Hooks offer a more efficient and readable approach.

How to Fix:

Use functional components and Hooks like useState and useEffect instead of class-based components. For example:// Instead of this class Example extends React.Component { constructor(props) { super(props); this.state = { count: 0 }; } render() { return <button onClick={() => this.setState({ count: this.state.count + 1 })}>Click {this.state.count}</button>; } }// Use this import { useState } from 'react'; function Example() { const [count, setCount] = useState(0); return <button onClick={() => setCount(count + 1)}>Click {count}</button>; }

2. Ignoring Key Props in Lists

The Mistake:

When rendering lists, developers often forget to include the key prop, which can lead to inefficient rendering and UI bugs.

How to Fix:

Ensure that each list item has a unique key:{items.map(item => ( <div key={item.id}>{item.name}</div> ))}

3. Overusing useEffect for Side Effects

The Mistake:

Many developers misuse useEffect, leading to unnecessary re-renders and performance issues.

How to Fix:

Only use useEffect when necessary, and optimize dependencies to prevent infinite loops:useEffect(() => { fetchData(); }, []); // Runs only once

4. Not Optimizing Performance with useMemo and useCallback

The Mistake:

Failing to memoize functions and values results in unnecessary re-renders.

How to Fix:

Use useMemo and useCallback to optimize expensive calculations and function references:const memoizedValue = useMemo(() => computeExpensiveValue(a, b), [a, b]); const memoizedCallback = useCallback(() => doSomething(a), [a]);

5. Modifying State Directly

The Mistake:

Updating state directly instead of using setState or useState can lead to unpredictable behavior.

How to Fix:

Always use state setters:const [data, setData] = useState([]); setData([...data, newItem]);

6. Not Using PropTypes or TypeScript

The Mistake:

Not validating props can lead to runtime errors and unexpected behavior.

How to Fix:

Use PropTypes or TypeScript for type checking:import PropTypes from 'prop-types'; function Component({ name }) { return <h1>{name}</h1>; } Component.propTypes = { name: PropTypes.string.isRequired, };

Conclusion

By avoiding these common mistakes in React JS for web development, you can build more efficient, maintainable, and scalable applications. Whether you’re a beginner or an experienced developer, following best practices will help you create a better user experience while optimizing your React applications.
