Different ways to use CSS

Published March 30, 2024 | By Matt

CSS (Cascading Style Sheets) gives you the power to transform the visual appearance of your web pages. From colors and fonts to layout and spacing, CSS offers a range of ways to achieve the look and feel you want. Understanding the different methods of applying CSS is key to efficient and maintainable web development.

1. Inline CSS

What is it? Inline CSS involves adding style rules directly within an HTML element’s style attribute.
Example:
HTML
<p style=”color: red; font-size: 18px;”>This text is red and large.</p>

Pros:
- Quick and convenient for minor, element-specific changes.
Cons:
- Can lead to bloated HTML code.
- More difficult to maintain as styles are scattered across your HTML.

2. Internal CSS

What is it? Internal CSS involves embedding a <style> block within the <head> section of your HTML document.
Example:
HTML
<head>
<style>
body {
background-color: lightblue;
}
h1 {
color: navy;
text-align: center;
}
</style>
</head>

Pros:
- Keeps styles organized within the same HTML file.
- Applies styles to all instances of a tag within the document.
Cons:
- Styles are limited to a single HTML page.

3. External CSS

What is it? External CSS uses a separate .css file that is linked to your HTML file using a <link> element within the <head>.
Example (styles.css):
CSS
body {
background-color: lightblue;
}
h1 {
color: navy;
text-align: center;
}

Example (HTML):
HTML
<head>
<link rel=”stylesheet” href=”styles.css”>
</head>

Pros:
- Best for maintainability – changes made in your CSS file update across all linked HTML pages.
- Clean separation of concerns (HTML for structure, CSS for style).
Cons:
- Requires an additional HTTP request (slightly slower initial loading).

When to Choose Which Method

Inline CSS: Use sparingly, mainly for quick testing or truly unique, element-specific styling overrides.
Internal CSS: Good for smaller projects or when styles are specific to a single page.
External CSS: The preferred method for most projects due to its benefits in reusability, organization, and maintainability.

Summing Up

Mastering these CSS methods gives you flexibility and efficiency. As you develop your web projects, consider the trade-offs of each to make the best stylistic choices!

How to Set up a React Webpack Application

Published March 27, 2024 | By Matt

Building modern web applications often means working with powerful tools that help you organize, optimize, and streamline your development process. Webpack is one such tool, a module bundler that takes your JavaScript code and its dependencies and packages them into a format ready for the browser. React is a fantastic library for creating dynamic and interactive user interfaces. In this guide, we’ll walk you through setting up a React project with Webpack, even if you’re new to these technologies.

What You’ll Need

Node.js and npm (or yarn): These are essential for working with JavaScript projects. If you don’t have them installed, download them from the Node.js website https://nodejs.org/.

Project Setup

Create a Folder: Start by creating a new directory for your project and open a terminal window in that directory.
Initialize Your Project: Run the following command to create a package.json file, which will manage your project’s dependencies:
Bash
npm init -y

Install Dependencies

Let’s install the necessary packages:

Bash

npm install react react-dom webpack webpack-cli webpack-dev-server –save-dev

React and ReactDOM: The core libraries for building React components.
Webpack and webpack-cli: Webpack itself and the command-line tools for working with it.
webpack-dev-server: A handy development server for testing your app.

Webpack Configuration (webpack.config.js)

Create the Configuration File: Create a file named webpack.config.js at the root of your project. Here’s a basic configuration to get you started:
JavaScript
const path = require(‘path’);
module.exports = {
entry: ‘./src/index.js’,
output: {
path: path.resolve(__dirname, ‘dist’),
filename: ‘bundle.js’
},
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: ‘babel-loader’
}
}
]
}
};

Explanation

- entry: The starting point for your application (typically index.js)
- output: Where Webpack should put the bundled code (here, a dist folder).
- module.rules: This tells Webpack how to handle different file types. Our rule uses babel-loader to process JavaScript and JSX (React) files.

Basic React Setup

Project Structure: Create a src folder and inside it, files named index.js and App.js.
App Component (App.js):
JavaScript
import React from ‘react’;
function App() {
return <h1>Hello from React and Webpack!</h1>;
}
export default App;

Entry Point (index.js):
JavaScript
import React from ‘react’;
import ReactDOM from ‘react-dom/client’;
import App from ‘./App’;
const root = ReactDOM.createRoot(document.getElementById(‘root’));
root.render(<App />);

Next Steps

Adding CSS: Explore Webpack’s CSS loaders (like style-loader and css-loader) to style your components.
Hot Module Replacement (HMR): Learn about HMR for seamless development updates.
Linting with ESLint: Keep your code clean and consistent with a linter.
Production Optimization: Prepare your project for deployment with Webpack’s production-focused features.

Conditional Rendering Basics in React

Published March 27, 2024 | By Matt

One of the core strengths of React lies in its ability to create dynamic and interactive user interfaces. Conditional rendering is a fundamental technique that allows you to control the display of elements or components based on specific conditions within your application. Whether you’re building a simple website or a complex app, conditional rendering will be essential in your React toolkit.

Methods of Conditional Rendering in React

There are several ways to achieve conditional rendering in your React applications. Let’s explore the most common ones:

1. If/Else Statements

The most straightforward approach is using plain JavaScript if and else statements within your components’ JSX.

JavaScript

function UserGreeting(props) {

if (props.isLoggedIn) {

return <h1>Welcome Back!</h1>;

} else {

return <h1>Please Log In.</h1>;

}

2. Ternary Operator

For shorter conditional expressions, the ternary operator offers a more concise syntax:

JavaScript

function UserStatus(props) {

return (

<p>You are currently: {props.isLoggedIn ? ‘Logged In’ : ‘Logged Out’}</p>

);

}

3. Logical && operator

This method is useful when you want to render something only if a condition is true:

JavaScript

function ShoppingCart(props) {

return (

<div>

<h1>Shopping Cart</h1>

{props.items.length > 0 && (

<p>You have {props.items.length} items in your cart.</p>

)}

</div>

);

}

4. Component Extraction

As your conditional logic becomes more complex, extracting conditional parts into separate components can often improve readability and code organization:

JavaScript

function LoggedInButton() {

return <button>Log Out</button>;

}

function LoggedOutButton() {

return <button>Log In</button>;

}

function UserPanel(props) {

return (

<div>

{props.isLoggedIn ? <LoggedInButton /> : <LoggedOutButton />}

</div>

);

}

Choosing the Right Method

For simple if/else scenarios, both if/else statements and the ternary operator are great.
The logical && operator is well-suited for conditionally rendering a single element.
When the logic gets more complex, breaking down your UI into smaller, reusable components improves maintainability.

Why Do We Need Conditional Rendering?

1. Dynamic User Interfaces

Adapting to User State: Imagine you’re building an e-commerce site. If a user isn’t logged in, you’d want to display options to “Sign In” or “Create Account.” Once they’re logged in, those options should switch to “My Account” or “Log Out.” Conditional rendering lets you control what the user sees based on their authentication status.
Responding to Data Changes: Your application might fetch data from an API. While that data loads, you want to show a “Loading…” message. Once the data arrives, you conditionally replace the loading message with the actual content.

2. User Experience (UX) Improvements

Personalization: You can tailor content based on user preferences or previous actions. For example, a news website might display a “Recommended For You” section based on the user’s reading history, determined by conditional logic.
Contextual Guidance: Providing instructions, help text, or tooltips only in specific situations can reduce information overload. For instance, you might show additional help text on a complex form when a user hovers over a particularly tricky field.

3. Performance Optimization

Selective Rendering: By conditionally rendering, you can prevent React from unnecessarily creating and updating elements in the DOM that aren’t currently needed. This can lead to performance gains in larger applications with complex UI structures, as rendering components can be computationally expensive.

4. Code Maintainability

Component Separation: Conditional rendering often encourages you to break down larger components into smaller, more focused ones. This improves readability and makes it easier to manage and reason about your codebase.
Clearer Logic: Explicitly stating the conditions that determine what is displayed helps you (and other developers) quickly understand what your components are doing under different circumstances.

Wrapping Up

Selecting the right conditional rendering method is important for creating clean React code. For simple “this or that” scenarios, if/else statements or the ternary operator are perfectly suitable. The logical AND (&&) operator is ideal when you only want to display a single element if a condition is true. As your logic gets more complex, break out different conditional cases into smaller components. This keeps your code organized, readable, and easier to maintain as your application grows. Prioritize the method that makes your code the most understandable, considering the current complexity and how it might evolve.

Using GraphQL in your Gatsby sites

Published March 27, 2024 | By Matt

Gatsby is a fantastic tool for building blazing-fast static websites. GraphQL simplifies how you manage data in your Gatsby projects, letting you fetch exactly what you need. Let’s dive in and get you started!

What is GraphQL?

The Problem It Solves: Traditional ways of fetching data can lead to getting too much or too little data. GraphQL lets you ask for only the specific fields you need.
Queries Define Your Data: With GraphQL, you write queries that match the shape of the data you want to receive.

Why GraphQL + Gatsby are a Perfect Pair

Built for Performance: Gatsby uses GraphQL to optimize data fetching, making your websites super fast.
Flexible Data Sourcing: Gatsby has plugins to pull data into GraphQL from a variety of sources (CMSs, markdown, databases, and more).

Setting Up GraphQL in Your Gatsby Project

Installation:
Bash
npm install gatsby-source-graphql

Configuration (gatsby-config.js) Provide a minimal example, assuming a basic GraphQL endpoint:
JavaScript
// gatsby-config.js
module.exports = {
plugins: [
{
resolve: `gatsby-source-graphql`,
options: {
typeName: `MySource`, // Replace with your source name
fieldName: `myData`, // Replace with how you’ll refer to this data
url: `https://my-graphql-endpoint.com`,
},
},
],
};

Using GraphQL Data in Your Components

The useStaticQuery Hook: Gatsby provides this hook to query GraphQL data.
Example Component:
JavaScript
import React from ‘react’;
import { useStaticQuery, graphql } from ‘gatsby’;
const BlogPost = () => {
const data = useStaticQuery(graphql`
query {
myData {
title
content
}
}
`);
return (
<div>
<h1>{data.myData.title}</h1>
<p>{data.myData.content}</p>
</div>
);
};
export default BlogPost;

Conclusion

This is just the beginning of your GraphQL and Gatsby journey! Experiment with it in your projects to see how it improves your development experience.

The Ultimate Guide to CSS Units

Published March 27, 2024 | By Matt

Ever wondered how websites magically fit on screens of all sizes? Or how can you adjust your text size if someone zooms in? The secret lies in mastering CSS units. In this guide, we’ll demystify units and help you choose the right ones to build stunning, adaptable layouts.

Absolute Units – The Fixed Sizes

Let’s start with absolute units. They have a fixed size, regardless of screen or other elements. The most common one is the pixel (px), but there are others like inches (in), centimeters (cm), and points (pt).

Pros: Easy to grasp and ideal for print stylesheets where physical size matters.
Cons: Inflexible for varied screen sizes. Using too many absolute units can make your website look awkward on smaller or larger displays.

Example:

CSS

.my-image {

width: 500px;

}

This code keeps .my-image at 500 pixels wide, no matter what.

Relative Units – Adapting to the Environment

This is where things get exciting! Relative units scale in relation to other things. Meet the stars:

rem: Relative to the current element’s font size.
Why They’re Awesome: These help you build responsive websites, ensuring your content looks great on any device. They’re also good for accessibility!

Examples:

CSS
p {
font-size: 1.2rem; /* 20% larger than the base font size */
}

CSS
.sidebar {
max-width: 30%; /* Takes up a maximum of 30% of its parent container */
}

Choosing the Right Unit (The Decision-Making Part)

So, how to pick the right tool for the job? Here’s a quick guide:

Pixels (px): Precision work (thin borders, fixed-size icons)
Percentages (%): Flexible layouts (e.g., making columns take up a certain percentage of their container).
rem: Global scaling (base font size, consistent margins throughout your site).
Viewport units (vw, vh): Elements that relate to the screen size (full-screen sections, large headings that scale with the window).
Watch Out! Be careful with nesting relative units like them within them. It can lead to unexpectedly large or tiny elements.

Units in Action – Real-World Use Cases

Responsive Layout Recipe:
CSS
.container {
max-width: 90%;
margin: 0 auto;
}
.column {
width: 30%;
float: left;
margin: 1rem;
}

This, along with some media queries, builds a basic multi-column layout.
User-Friendly Text: Use relative font sizes (em or rem) to allow people with visual impairments to zoom in on your text more easily.

Conclusion

Think of CSS units as your layout toolkit. Here’s a handy cheat sheet:

px: Fixed sizes
em: Relative to the current font size
rem: Relative to the root font size
%: Relative to the parent element
vw/vh: Relative to the viewport width/height

The more you practice, the more intuitive it becomes. Inspect the code of websites you admire to see how they use units!

JavaScript DOM Methods and Properties

Published March 25, 2024 | By Matt

Have you ever wondered how web pages go from static blocks of text to the interactive experiences we use every day? Think about buttons that change things, menus that appear when you hover over them, or forms that magically validate your input. The secret lies in the Document Object Model (DOM) and JavaScript’s ability to manipulate it.

The DOM Made Simple

Imagine your HTML page as a family tree. Each HTML tag is like a member of that family. At the top, you have the <html> element as the grandparent, then elements like <head> and <body> as its children, and so on. The DOM is this tree-like representation that JavaScript can interact with.

Why It Matters

Understanding the DOM is the foundation for adding any kind of dynamic behavior to your web pages. Without it, websites would be pretty boring!

DOM Properties – Your Access Points

Think of DOM properties as the way you describe different elements in that HTML family tree.

Key Node Properties
- nodeType: Tells you if you’re dealing with an element, text, or something else.
- nodeName: The tag name of an element (like “DIV,” “P,” “IMG”).
- nodeValue: The actual text content within a text node.
Document Properties
- document.body: Represents the entire <body> section of your page.
- document.title: Contains the text within the <title> tag.

Example: Changing the Page Title

JavaScript

document.title = “My New Awesome Title!”;

DOM Methods – Your Power Tools

If properties are for describing elements, methods are the actions you can take on them.

The Art of Selection
- getElementById(‘my-button’): Grabs a single element with the specified ID.
- getElementsByTagName(‘p’): Returns a collection of all paragraph elements.
- querySelectorAll(‘.special-image’): The most flexible, uses CSS-like selectors.
Transformation
- createElement(): Lets you build new HTML elements from scratch.
- appendChild(): Adds a new element as a child of another.
- removeChild(): Removes an element from the page.
Style and Content
- element.textContent: Gets or sets the plain text inside an element.
- element.innerHTML: Gets or sets the full HTML content within an element.
- element.style.color = ‘blue’: Changes CSS styles directly.

It’s Alive! Events and the DOM

The DOM lets you react to user actions:

Brief Intro to Events: Clicks, hovers, form submissions—these are all events.
Example: A Revealing Button

JavaScript

const button = document.getElementById(‘secret-button’);

button.addEventListener(‘click’, function() {

const hiddenMessage = document.getElementById(‘secret-message’);

hiddenMessage.style.display = ‘block’;

});

Leveling Up

There’s Always More: This is a foundational guide – explore resources like MDN Web Docs to dive deeper.
Frameworks and Libraries: React, Vue.js, and others streamline DOM manipulation for large projects.

Conclusion

Now that you have a grasp of the DOM, you’re ready to start making your websites interactive. Start small, experiment, and have fun!

React Router Navigation and Redirects

Published March 24, 2024 | By Matt

Building dynamic React applications often necessitates controlling how users move between different sections of your website. React Router is a powerful library that simplifies routing, but it also provides tools for programmatic navigation (using the navigate function) and automatic redirects (using <Navigate> and related techniques). In this post, we’ll explore both concepts and see how they work in practice, especially with the latest version of React Router (v6).

React Router Navigation

Click here to deploy, manage, and scale cloud applications EASY with $200 credit

“react router navigate”

The navigate function in React Router lets you change the current URL and trigger a navigation within your React app, even from outside of your React components.

Core Usage:

JavaScript

import { useNavigate } from ‘react-router-dom’;

function MyComponent() {

const navigate = useNavigate();

const handleButtonClick = () => {

navigate(‘/profile’); // Navigates to the ‘/profile’ route

};

return (

<button onClick={handleButtonClick}>Go to Profile</button>

);

}

Common Use Cases:

Form Submissions: Redirect to a success page after form submission.
Data Fetching: Navigate to a content page after data is loaded.
Event Handling: Navigate in response to any button clicks or user interactions.

Options

replace: true: Replace the current history entry instead of pushing a new one (useful to prevent the back button from returning to the previous form page).

“react router redirect”

Redirects automatically send users to a different route based on conditions you define.

React Router v5 (Older)

Prior to v6, the <Redirect> component was the standard:

JavaScript

import { Redirect } from ‘react-router-dom’;

</Route>

React Router v6 (Current)

<Navigate> Component: Used within JSX for in-component redirects.
JavaScript
import { Navigate } from ‘react-router-dom’;
function HomePage() {
const isLoggedIn = false;
if (!isLoggedIn) {
return <Navigate to=”/login” replace />;
}
// … Rest of home page content
}
useNavigate Hook: For redirects outside of components or more complex logic handling

Conditional Redirects

Route protection based on authentication is a common redirect use case.

Taking Your Navigation Skills to the Next Level: Advanced React Router Techniques

While the basic navigation and redirect patterns cover many common scenarios, React Router’s capabilities extend much further. Let’s explore some advanced techniques and best practices to elevate your navigation game.

Elaborated Use Cases: Real-World Examples

Form Submissions with Feedback:

JavaScript

import { useNavigate } from ‘react-router-dom’;

import { useState } from ‘react’;

function OrderForm() {

const navigate = useNavigate();

const [submissionStatus, setSubmissionStatus] = useState(null);

const handleSubmit = async (formData) => {

try {

// Send form data (e.g., to API)

await fetch(‘/api/orders’, {

method: ‘POST’,

body: JSON.stringify(formData)

});

// Successful submission

setSubmissionStatus(‘success’);

navigate(‘/order-success’, { state: { formData } });

} catch (error) {

// Error handling

setSubmissionStatus(‘error’);

}

};

// … form UI, including conditional rendering based on submissionStatus

}

In this example, we add error handling and use the submissionStatus state to provide visual feedback to the user before redirection.

Data Fetching with Loading States:

JavaScript

import { useNavigate, useParams } from ‘react-router-dom’;

import { useEffect, useState } from ‘react’;

function ProductPage() {

const { productId } = useParams();

const navigate = useNavigate();

const [product, setProduct] = useState(null);

const [isLoading, setIsLoading] = useState(true);

useEffect(() => {

async function fetchData() {

const response = await fetch(`/api/products/${productId}`);

const data = await response.json();

setProduct(data);

setIsLoading(false);

}

fetchData();

}, [productId]);

if (isLoading) {

return <div>Loading…</div>;

}

if (!product) {

return <Navigate to=”/not-found” />;

}

// … render product details

}

Here, we fetch product data based on the route parameter (productId). While loading, we display a “Loading…” message; if no product is found, we redirect to a “Not Found” page.

Advanced Redirect Scenarios and Troubleshooting

Role-Based Redirects: Use conditional logic within your components or route definitions to redirect users based on their authentication status or roles.
Delayed Redirects: Leverage setTimeout within a useEffect hook to trigger a redirect after a specified delay (e.g., for splash screens).
Query Parameter Preservation: Utilize the useLocation hook to access and preserve query parameters during redirects.
Infinite Redirects: Carefully examine your redirect conditions to ensure they don’t create endless loops.
Redirect Flash: Consider using a loading state or a transition animation to prevent a brief flash of the redirected page.
