React Router Crash Course: Step-by-Step Guide

React Router is the standard routing library for React. In this crash course, we’ll build a simple multi-page app using React Router v6+ and Vite. Let’s get started!

1. Project Setup

First, create a new React project using Vite:

npm create vite@latest react-router-crash-course -- --template react

Install React Router:

npm install react-router-dom

2. Project Structure

Organize your files as follows:

src/

3. Setting Up the Router

In main.jsx, wrap your app with BrowserRouter:

import React from "react";

4. Defining Routes

In App.jsx, set up your routes:

import { Routes, Route } from "react-router-dom";

5. Creating Navigation

In components/Navigation.jsx, add navigation links:

import { NavLink } from "react-router-dom";

6. Building Pages

Create simple components for each page in the pages/ directory. Example for HomePage.jsx:

function HomePage() {

Repeat for AboutPage.jsx, ContactPage.jsx, etc.

7. Dynamic Routes

In ProductDetailPage.jsx, use the useParams hook to get the product ID:

import { useParams } from "react-router-dom";

8. Nested Routes (Dashboard Example)

In DashboardLayout.jsx, use the Outlet component:

import { Outlet, NavLink } from "react-router-dom";

9. Handling 404s

In NotFoundPage.jsx:

function NotFoundPage() {

10. Running the App

Start your development server:

npm run dev

Visit

http://localhost:5173

to see your app in action!

Conclusion

You now have a working React app with multiple pages, nested routes, dynamic routes, and a 404 page—all powered by React Router. Experiment by adding more pages or features!

In this tutorial, you'll get a complete understanding of React components including how to build and structure them using best practices. You'll learn about functional components, props, state, JSX, hooks, composition, and how to break an app into reusable modules.

🔧 Step-by-Step Tutorial

1. 📦 What is a Component in React?

* A component is a reusable and self-contained part of the UI.

* It’s either a function or class (function preferred).

* Allows splitting the UI into isolated pieces.

function MyComponent() {

2. 🧩 Types of Components

✅ Functional Components (modern, preferred)

const Welcome = () =>

❌ Class Components (legacy)

class Welcome extends React.Component {

3. 🛠 Using Props

Props = "properties" → input data passed to a component.They are read-only and passed via JSX attributes.

function Greeting({ name }) {

Hello, {name}!

4. 🔁 State Management

State = data that can change.Use useState to manage it in a functional component.

const [count, setCount] = useState(0);

Updating state triggers a re-render of the component.

5. ⏱ Lifecycle with useEffect

React uses useEffect() for side effects like fetching data.

useEffect(() => {

6. 💻 JSX Syntax

JSX = HTML + JavaScript hybrid syntax.It compiles to React.createElement() behind the scenes.

const App = () => (

7. 🧱 Component Composition

Components can include other components → reusable UIs.

const Page = () => (

8. 📦 Exporting and Importing Components

Create a component:

const Footer = () =>

Use it:

import Footer from './components/Footer';

9. 📁 Project Refactor Example

We extracted Footer.jsx, Home.jsx, Page.jsx, RecipePage.jsx, RecipeCard.jsx, and RecipeModal.jsx components into a structured folder system.

Folder Structure:

src/

10. 📚 Best Practices

* ✅ Name components with capital letters

* ✅ One export default per file

* ✅ Keep components small & focused

* ✅ Use props to customize components

* ✅ Return a single parent element

🔍 Implement Search & Category Filtering in React with TailwindCSS (2025 Guide)

In this guide, you’ll learn how to implement powerful search and category filtering in a React application using TailwindCSS for styling. This builds on a previous project where we created a responsive recipe website.

By the end of this tutorial, you'll be able to:

* Filter recipe cards by text input

* Filter by category dropdown

* Clear search with a single click

* Ensure case-insensitive matching

✅ Prerequisites

* A React app already set up (ideally with TailwindCSS + recipe data)

* Basic understanding of React state and hooks

🧱 Step 1: Create State for Search and Category

Inside your RecipesPage.jsx (or App.jsx if everything is in one file):

const [searchQuery, setSearchQuery] = useState("");

🎨 Step 2: Create the UI

🔍 Search + Filter Inputs

⚙️ Step 3: Search Logic with useEffect

useEffect(() => {

This runs every time the search query or category changes.

📦 Step 4: Display Filtered Recipes

No recipes found.

🧠 Bonus: Tips

* Use toLowerCase() to make searching case-insensitive

* Use Set to generate unique categories

* Add debounce if your search data is large

* For UX, make the clear button instantly reset filters

🚀 React.js Crash Course 2025 – Build Your First App from Scratch

Welcome to this beginner-friendly React.js crash course for 2025! Whether you're transitioning from HTML, CSS, and JavaScript or starting fresh, this tutorial will give you a rock-solid foundation in React with best practices, clean structure, and modern JavaScript techniques.

📦 Step 1: What Is React.js?

React is a JavaScript library for building user interfaces, created and maintained by Meta (Facebook). It allows you to create reusable components, use a virtual DOM for faster rendering, and structure your frontend with clean, component-based architecture.

React is not a full-blown framework like Angular—think of it as the view layer of your app. It’s great for building single-page applications (SPAs).

🧱 Step 2: Setting Up React

✅ Prerequisites:

* Node.js & npm (Install from nodejs.org)

* A code editor like VS Code

🛠 Create a New React App

npx create-react-app my-app

Replace my-app with your project name.

Navigate into your app:

cd my-app

Start the app:

npm start

Your React app will open at

http://localhost:3000

📂 Step 3: Project Structure Overview

React generates this structure:

my-app/

* App.js: Main component

* App.css: Main stylesheet

* index.js: App entry point

🧩 Step 4: Understanding JSX & Components

Create a Functional Component

// src/components/Welcome.jsx

Import & Use It

// App.js

JSX Notes

* Always return a single root element (use <>... if needed).

* Use className instead of class.

⚛️ Step 5: Using State with useState

import { useState } from 'react';

Count: {count}

⏱ Step 6: Using Effects with useEffect

import { useEffect, useState } from 'react';

Time passed: {seconds}s

🎨 Step 7: Styling in React

Option 1: CSS File

/* App.css */

Option 2: Inline Style

const myStyle = {

🔁 Step 8: Conditional Rendering

const [isLoggedIn, setIsLoggedIn] = useState(false);

Or with &&:

{hasAccess && }

🧾 Step 9: Lists and Keys

const items = ["A", "B", "C"];

⚠️ Use unique IDs for production (not index as key).

🗂 Step 10: Folder Structure Best Practices

src/

Clean up unused files like logo.svg, App.test.js, etc.

🚀 Next Steps

* Use React Router for navigation

* Deploy using Vercel or Netlify

* Add form handling and API calls

🔧 Getting Started: Setup Tailwind CSS 4.1 Without a Build Tool

To keep things simple, we’ll use Tailwind via the CDN—no frameworks, no build tools.

Tailwind 4.1 Demo

You can now use all of Tailwind’s new features right in your HTML.

🎨 1. Drop Shadow with Color

Standard shadows often fall flat, especially in dark mode. Tailwind 4.1 adds color drop shadows to give your elements more punch.

💡 Example:

To control intensity, use shade values like drop-shadow-red-500, drop-shadow-blue-300, etc.

✨ 2. Text Shadows (with Color!)

Text shadows bring another layer of depth, especially on headings and banners.

💡 Example:

You can go from text-shadow-2xs to text-shadow-lg, and add color variants like text-shadow-blue-400.

🖼️ 3. Mask Utilities for Images

You can now mask images or elements using directional gradients.

💡 Example:

This creates a soft fade from bottom to top or vice versa. You can tweak directions with classes like mask-top, mask-left, mask-right.

⚠️ Mask gradients might look different in dark mode.

⚙️ 4. Seamless Dark Mode

Tailwind 4.1 improves dark mode handling—just use the dark: prefix, no extra configuration needed.

💡 Example:

✅ Other Notable Improvements

* Text wrapping control via overflow-wrap

* Improved browser compatibility

* Less need for configuration files

* CSS @import now works for simpler integrations
