I finished coding my Rogue Trader character sheet template! It's now open sourced on GitHub 🤖

☆ Features

Display your character's stats in (almost) the same way as you've seen in Warhammer 40,000: Rogue Trader CRPG

Multiple sections for character building:

Summary: Character origin info, alignment level, history, and biography.

Features: Show off your build by listing abilities & talents that your character has gained throughout the course of the game.

Inventory: Your Rogue Trader's equipment, armour, etc. goes here.

Relations: Detail the relationship of your Rogue Trader and their retinue members.

Gallery: Place to show off your fanart, commissioned art, fanfics, playlist. Anything goes!

Cool floating servo skulls (only visible in certain screen sizes).

Responsive. Not horrible to look at even in small screens.

☆ Requirements

You would need a static site hosting service for this to work. I recommend Neocities or GitHub pages. Both are free.

Some experience with using npm.

Some experience with basic HTML and JS object/JSON is recommended.

I really wish that it's easier to use and set up, but it's just not possible due to the tech stack I chose initially... I did write a beginner's tutorial on the repository's wiki, but I don't know if it makes sense to normal people who do not code... If you have any questions, let me know and I'll see what I can do.

Tech stack: SvelteKit, SCSS, TypeScript

Bonus:

Name too long? No problem :)

Your iterator "voice" clips are cool as fuckkkk would you ever consider taking commissions for them or doing a tutorial on how you make them? You have the sound of them totally nailed

PROOOOBABLY I can do a tutorial but I'm pretty averse to commissions since all my art is self-fufilling

The process is super easy, really, so long as you have a decent audio editing software and fl studio

I still have 2 more clips I want to make before I probably never touch it again for 7 months and I'll do a recording of my process making them

Though if you don't want to wait here are the steps I usually take for making iterator voices - Take a compilation of voice clips from whatever source you want - Reverse + speed up the audio slightly - Adjust pitch to whatever feels right - Add reverb/phaser/whatever you effects you think fit the iterator in question - Splice the audio to HELL. Make it cut out occasionally or lag and repeat

Usually it looks something like this when I'm done: (Quartz, NPM, and Sulfur respectively)

For a bonus you can reverse and pitch edit your results and see if you can still hear the original audio

Mini React.js Tips #5 | Resources ✨

Continuing the #mini react tips series, this time it's SCSS/SASS' time to shine! CSS is great and all but I am a SCSS girlie and I wanted to learn how to add SCSS files to my projects. It's a bit different to how to add CSS files to your project so heads up~!

What you'll need:

know how to create a React project >> click

know the default React project's file structure >> click

know how to create a component >> click

know basic SCSS or SASS

basic knowledge of using the Terminal

What The Project Will Look Like:

*very basic but just want some SCSS styling to prove that the tips work~!

Big disclaimer: I have deleted all the code inside of the App()'s return() so that the default project is gone and the guide starts on a clean slate. I have also created a NavBar component beforehand as my testing component for this guide~!

[ 1 ] Open Terminal And Install Sass: Launch the terminal within your project folder. Execute the following command to install Sass as a development dependency for your project:

npm install -D sass

[ 2 ] Create SCSS File: In the 'src' folder, create your SCSS file - it ends with .scss for SCSS files and .sass for SASS files. Feel free to organize it into subfolders for a structured project.

[ 3 ] Style Your SCSS: Open the newly created SCSS file and add your styles, take advantage of variables, nesting, and more. (This is not all of my SCSS code):

[ 4 ] Import SCSS in Component: In the React component file where you want to apply these styles, import your SCSS file at the top:

import './[location of you SCSS/SASS file]';

[ 5 ] Run the Development Server: Start your development server with the command in the Terminal (the 'Local' link) + make sure your component is in the App() in App.jsx:

npm run dev

Congratulations! You've successfully added SCSS/SASS to your React project~!

06/09/2023 || Day 75

Oh god, I feel like it's been forever since I did some programming even though it's really only been 5 days. However, apparently that was a good enough break for me because I feel rejuvenated and was able to consume more knowledge on programming. So, here's a quick list of things I accomplished today:

Did a refresher on the Bubble Sort and Insertion Sort sorting algorithms, since it's been a few months since I touched their implementation

Continued on with Node.js tutorial videos

Started mySQL videos (specifically, how to use it with Javascript and Node.js)

Abandoned the mySQL videos/topic after 20 mins and decided to get my hands dirty with actually using and connecting Node.js to a frontend client. Will do this with API calls

Realized I didn't want to have to constantly install npm packages when I switch between my laptop and my PC, so I started watching a tutorial on Docker

All in all, I did a bunch of random programming-related stuff today, but didn't delve deeply into any one topic. Tomorrow I plan on actually using Docker to set up a new project that will use Node.js to deal with server stuff and React to deal with the client-side UI. It's gonna be a small project, but hopefully it'll be fun! Will post more about it tmr.

Master React: A Complete React Tutorial for Beginners

In the ever-evolving landscape of web development, React has emerged as one of the most powerful and popular JavaScript libraries for building user interfaces. Developed and maintained by Facebook, React allows developers to create dynamic, high-performance web applications with ease. If you’re a beginner looking to dive into the world of React, this comprehensive tutorial, "Master React: A Complete React Tutorial for Beginners," will guide you through the essential concepts, tools, and techniques needed to become proficient in React development.

What is React?

React is a declarative, component-based library that enables developers to build reusable UI components. Its primary goal is to make the process of creating interactive user interfaces more efficient and manageable. Unlike traditional web development approaches that manipulate the Document Object Model (DOM) directly, React uses a virtual DOM to optimize rendering performance. This means that React only updates the parts of the UI that have changed, resulting in faster and more responsive applications.

Why Learn React?

Learning React is a valuable investment for any aspiring web developer. Here are a few reasons why you should consider mastering React:

Popularity and Demand: React is widely used by companies of all sizes, from startups to tech giants like Facebook, Instagram, and Airbnb. Proficiency in React can significantly enhance your job prospects and career opportunities. Component-Based Architecture: React’s component-based structure promotes reusability and modularity, making it easier to manage and scale applications. This approach allows developers to break down complex UIs into smaller, manageable pieces. Rich Ecosystem: React has a vast ecosystem of libraries and tools that complement its functionality. From state management solutions like Redux to routing libraries like React Router, the React ecosystem provides everything you need to build robust applications. Strong Community Support: With a large and active community, finding resources, tutorials, and support for React development is easier than ever. Whether you’re facing a coding challenge or looking for best practices, the community is there to help.

Setting Up Your React Environment

Before diving into coding, you need to set up your development environment. The easiest way to get started with React is by using the Create React App (CRA) tool, which sets up a new React project with a single command. To create a new React application, follow these steps:

Install Node.js: Ensure you have Node.js installed on your machine. You can download it from the official website.

Create a New React App: Open your terminal and run the following command:

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

This command creates a new directory called my-first-react-app and starts a development server that you can access at http://localhost:3000.

Understanding React Components

At the heart of React are components. A component is a self-contained piece of UI that can be reused throughout your application. There are two main types of components in React:

Functional Components: These are JavaScript functions that return JSX (JavaScript XML), which looks similar to HTML. Functional components are simpler and easier to read, making them the preferred choice for most developers. Example of a functional component:

function Welcome(props) { return <h1>Hello, {props.name}!</h1>; }

Class Components: These are ES6 classes that extend the React.Component class. Class components can hold state and lifecycle methods, but with the introduction of hooks, functional components are now more commonly used. Example of a class component:

class Welcome extends React.Component { render() { return <h1>Hello, {this.props.name}!</h1>; } }

JSX: The Syntax of React

JSX is a syntax extension for JavaScript that allows you to write HTML-like code within your JavaScript files. It makes it easier to visualize the structure of your UI. JSX expressions can include JavaScript expressions wrapped in curly braces {}.

Example of JSX:const element = <h1>Hello, world!</h1>;

State and Props: Managing Data in React

In React, data flows in one direction, from parent components to child components. This is achieved through props (short for properties) and state.

Props: Props are read-only attributes passed from a parent component to a child component. They allow you to customize components and make them reusable. Example of using props:

function Greeting(props) { return <h1>Welcome, {props.name}!</h1>; }

State: State is a built-in object that allows components to manage their own data. Unlike props, state is mutable and can be updated using the setState method in class components or the useState hook in functional components. Example of using state with hooks:

import React, { useState } from 'react'; function Counter() { const [count, setCount] = useState(0); return ( <div> <p>You clicked {count} times</p> <button onClick={() => setCount(count + 1)}>Click me</button> </div> ); }

Lifecycle Methods and Hooks

In class components, React provides lifecycle methods that allow you to run code at specific points in a component's life, such as when it mounts or unmounts. Common lifecycle methods include componentDidMount, componentDidUpdate, and componentWillUnmount.

With the introduction of hooks in React 16.8, functional components can now manage side effects and lifecycle events using the useEffect hook. This allows for cleaner and more concise code.

Example of using useEffect:import React, { useState, useEffect } from 'react'; function DataFetcher() { const [data, setData] = useState(null); useEffect(() => { fetch('https://api.example.com/data') .then(response => response.json()) .then(data => setData(data)); }, []); // Empty array means this runs once on mount return <div>{data ? JSON.stringify(data) : 'Loading...'}</div>; }

Routing with React Router

For building single-page applications (SPAs), React Router is an essential library that enables navigation between different components without refreshing the page. It allows you to define routes and render components based on the current URL.

Example of setting up React Router:import { BrowserRouter as Router, Route, Switch } from 'react-router-dom'; function App() { return ( <Router> <Switch> <Route path="/about" component={About} /> <Route path="/" component={Home} /> </Switch> </Router> ); }

State Management with Context and Redux

As your application grows, managing state across multiple components can become challenging. React Context provides a way to share data globally without prop drilling, while Redux is a popular state management library that offers a centralized store and predictable state updates.

Best Practices for React Development

To ensure your React applications are maintainable and efficient, consider the following best practices:

Keep Components Small and Focused: Each component should have a single responsibility, making it easier to understand and test.

Use Functional Components and Hooks: Prefer functional components and hooks over class components for cleaner and more concise code.

Leverage PropTypes or TypeScript: Use PropTypes for type checking or consider using TypeScript for static type checking to catch errors early.

Optimize Performance: Use React. Memo to prevent unnecessary re-renders and implement lazy loading for components to improve performance. Maintain a Modular Folder Structure: Organize your project files in a way that promotes modularity and ease of navigation.

Building Real-World Projects

The best way to solidify your React skills is by building real-world projects. Start with simple applications like a to-do list or a weather app, and gradually move on to more complex projects like an e-commerce site or a social media platform. This hands-on experience will help you apply what you’ve learned and prepare you for real-world development challenges.

Conclusion

Mastering React is a rewarding journey that opens up numerous opportunities in web development. This tutorial, "Master React: A Complete React Tutorial for Beginners," has provided you with a solid foundation in React concepts, tools, and best practices. By dedicating time to practice and build projects, you will gain the confidence and skills needed to create dynamic, high-performance web applications.

Socket.IO setup

Building Real-Time Applications with Socket.IO setup: Step-by-Step Tutorial

Socket.IO setup. In today's interconnected world, real-time applications are becoming increasingly essential. Whether it's for live chat applications, collaborative tools, or gaming, real-time communication enhances user engagement and makes interactions more dynamic. One powerful tool for building real-time applications is Socket.IO. In this tutorial, we will guide you through the process of building a real-time application using Socket.IO, focusing on key concepts and practical implementation. What is Socket.IO? Socket.IO is a JavaScript library that enables real-time, bidirectional communication between web clients (like browsers) and servers. Unlike traditional HTTP requests, which follow a request-response model, Socket.IO provides a persistent connection, enabling instant data exchange between the client and server. Socket.IO works on top of WebSockets, but it provides fallback mechanisms for environments where WebSockets may not be available. This ensures that real-time communication is possible in a wide range of conditions, making it a versatile choice for building interactive web applications. Prerequisites Before we dive into the tutorial, make sure you have the following: Basic knowledge of JavaScript and Node.js Node.js installed on your machine. You can download it from nodejs.org. A code editor (like Visual Studio Code or Sublime Text). Step 1: Setting Up the Project Start by setting up a basic Node.js project. Create a new directory for your project: bash mkdir real-time-app cd real-time-app Initialize a new Node.js project: bash npm init -y Install Express and Socket.IO: bash npm install express socket.io Express is a lightweight web framework for Node.js that simplifies the creation of web servers. Socket.IO will handle real-time communication between the server and the client. Step 2: Create the Server Now that we've set up the dependencies, let's create a simple server. Create a file called server.js in the project root: js const express = require('express'); const http = require('http'); const socketIo = require('socket.io');// Create an instance of Express app const app = express();// Create an HTTP server const server = http.createServer(app); // Initialize Socket.IO with the HTTP server const io = socketIo(server); // Serve static files (like HTML, CSS, JS) app.use(express.static('public')); // Handle socket connection io.on('connection', (socket) => { console.log('a user connected'); // Handle message from client socket.on('chat message', (msg) => { io.emit('chat message', msg); // Emit the message to all clients }); // Handle disconnect socket.on('disconnect', () => { console.log('user disconnected'); }); }); // Start the server server.listen(3000, () => { console.log('Server is running on http://localhost:3000'); }); Step 3: Create the Client-Side Next, we need to create the client-side code that will connect to the server and send/receive messages in real time. Create a public folder inside the project directory. In the public folder, create an index.html file: html Real-Time Chat Real-Time Chat Application Send const socket = io(); // Connect to the server// Listen for messages from the server socket.on('chat message', function(msg){ const li = document.createElement('li'); li.textContent = msg; document.getElementById('messages').appendChild(li); }); // Handle form submission const form = document.getElementById('form'); form.addEventListener('submit', function(event){ event.preventDefault(); const input = document.getElementById('input'); socket.emit('chat message', input.value); // Send the message to the server input.value = ''; // Clear the input field }); Step 4: Run the Application With the server and client code in place, it’s time to run the application! In your terminal, run the following command: bash node server.js Open your browser and go to http://localhost:3000. You should see the chat interface. Open multiple browser windows or tabs to simulate multiple users. Type a message in the input field and click "Send." You should see the message appear in real-time in all open windows/tabs. Step 5: Enhancements and Improvements Congratulations! You've built a basic real-time chat application using Socket.IO. To enhance the application, consider adding the following features: User authentication: Allow users to log in before they can send messages. Private messaging: Enable users to send messages to specific individuals. Message persistence: Use a database (e.g., MongoDB) to store chat history. Typing indicators: Show when a user is typing a message in real time. Emoji support: Allow users to send emojis and other media. Conclusion Socket.IO setup. In this tutorial, we covered the basics of building a real-time application using Socket.IO. We walked through setting up a Node.js server with Express, integrating Socket.IO for real-time communication, and creating a simple chat interface on the client side. Socket.IO makes it easy to add real-time features to your web applications, enabling more dynamic and interactive experiences for users. With this foundation, you can now start exploring more advanced real-time features and take your applications to the next level! Read the full article

Understanding ReactJS – A Beginner-Friendly Guide

Introduction

ReactJS is widely used in various industries, including web development company in Bangalore, which leverage its capabilities to build dynamic and scalable applications.

Imagine a world where building a website is like assembling LEGO blocks—each block representing a specific function. This is exactly what ReactJS does! ReactJS is a powerful JavaScript library developed by Facebook that helps developers create interactive user interfaces in a structured, reusable, and efficient way. Since its release in 2013, it has become a game-changer in web development, powering applications like Facebook, Instagram, and Airbnb.

ReactJS has revolutionized front-end development by making it easier to build large-scale applications with reusable components and a seamless user experience. In this guide, we will break down ReactJS into simple, digestible concepts, making it easy for beginners to grasp and use effectively.

What is ReactJS?

ReactJS is an open-source JavaScript library designed to create fast and dynamic web applications. Unlike traditional HTML and JavaScript, where each change refreshes the entire webpage, React uses a smart feature called the Virtual DOM to update only the necessary parts. This significantly boosts performance and enhances user experience.

Why Choose ReactJS?

Component-Based Structure: Applications are built using reusable components, making development organized and efficient.

Lightning-Fast Performance: The virtual DOM optimizes updates, improving speed.

Strong Community & Support: With a vast developer community, solutions and tutorials are readily available.

SEO-Friendly: Unlike other JavaScript-heavy frameworks, React supports server-side rendering, improving search engine rankings.

Scalability: From small projects to large enterprise applications, React scales seamlessly.

Cross-Platform Development: React Native, a React-based framework, allows developers to build mobile applications using the same concepts.

Core Concepts of ReactJS

1. Components – The Building Blocks

Think of React components as small, reusable pieces of a website, just like individual LEGO pieces. A component can be a button, a form, or an entire page!

There are two types of components:

Functional Components – Simple, stateless components that return UI elements.

Class Components – More powerful components that can manage their own state and lifecycle events.

Components help in modular development, making it easier to maintain and scale applications.

2. JSX (JavaScript XML) – Writing HTML in JavaScript

React uses JSX, a special syntax that looks like HTML but works inside JavaScript. JSX makes UI code easier to read and write, reducing complexity and improving development speed.

3. Props – Passing Data Between Components

Props (short for properties) allow components to communicate with each other by passing data. They help in making components dynamic and reusable.

4. State – Managing Dynamic Data

State is used to store and manage data that can change over time. Unlike props, which are read-only, state can be updated dynamically. This makes applications more interactive and responsive.

5. Virtual DOM – The Secret Behind React’s Speed

Traditional web applications update the entire webpage when a change occurs. React, however, creates a Virtual DOM, a lightweight copy of the actual DOM. Instead of reloading everything, it updates only the changed elements, making applications incredibly fast.

Getting Started with ReactJS

Setting up a React project is simple. Follow these steps:

Install Node.js and npm: React requires Node.js, which comes with npm (Node Package Manager).

Create a React App: Open the terminal and run npx create-react-app my-app.

Navigate to the project folder: Use cd my-app.

Start the development server: Run npm start. Your app will open in the browser at http://localhost:3000/.

This setup creates a structured environment to build React applications efficiently.

Advanced React Features

1. React Hooks – Making Functional Components More Powerful

Hooks allow functional components to manage state and side effects. The useState hook is one of the most commonly used, replacing class components in many cases.

2. React Router – Handling Multiple Pages

React applications often need navigation between different pages. React Router enables this functionality without requiring full-page reloads, ensuring smooth transitions between components.

3. Redux – Managing Complex Application State

As applications grow, managing state becomes challenging. Redux is a popular library that helps manage state in a predictable and structured way, making applications easier to debug and maintain.

4. Context API – An Alternative to Redux

For applications that do not require a complex state management system, React provides the Context API. It allows data to be passed globally without the need for prop drilling, improving code efficiency.

5. Server-Side Rendering (SSR) – Improving Performance and SEO

React supports SSR, which allows content to be rendered on the server before being sent to the client. This enhances page speed, improves SEO, and ensures better user engagement.

Best Practices for React Development

Keep Components Small and Focused: Each component should have a single responsibility.

Use Functional Components and Hooks: They make code simpler and more readable.

Optimize Performance: Use techniques like lazy loading, memoization, and avoiding unnecessary re-renders.

Follow a Consistent Folder Structure: Organizing components, assets, and utilities properly improves maintainability.

Use Error Boundaries: They help in handling errors gracefully without breaking the entire application.

Write Clean and Reusable Code: Reusing components and avoiding redundant code improves efficiency.

Future of ReactJS

React continues to evolve with new features and improvements. Some trends shaping its future include:

Concurrent Mode: Improving performance by allowing multiple tasks to run simultaneously.

React Server Components: Enhancing server-side capabilities.

Better Developer Experience: With updates in developer tools and debugging features.

With strong community support and continuous updates, ReactJS remains a top choice for front-end development.

Conclusion

ReactJS is a powerful tool that makes web development easier, faster, and more efficient. With its component-based architecture, virtual DOM, and advanced features like hooks and routing, it’s no wonder that companies worldwide rely on it.

By learning React, you unlock the potential to create stunning, high-performance web applications. Whether you’re a beginner or an experienced developer, mastering ReactJS will open doors to countless opportunities in the tech world.

With its vast ecosystem, seamless integrations, and continuous improvements, ReactJS remains at the forefront of web development. If you're planning to dive into front-end development, ReactJS is the perfect technology to master.

What is React.js? A Complete Guide for 2025

What is React.js?

What is React js? A Complete Guide for 2025 dives deep into React.js, the groundbreaking JavaScript library that has transformed the way developers build dynamic and interactive user interfaces. As one of the most powerful and widely adopted tools in modern web development, React, originally created by Facebook (now Meta), continues to dominate the industry with its efficient, component-based architecture and unparalleled flexibility. Whether you're a beginner or an experienced developer, this guide will equip you with everything you need to master React.js in 2025 and beyond.

Reasons for Popularity:

Fast and efficient: Utilizes Virtual DOM for performance and optimization

Component-based: Allows for code reusability and organization

Huge ecosystem: There are many libraries and tools out there that enhance the development experience

It is backed by Meta: All the time updates and new features are added

History and Evolution of React.js

React.js was originally launched in 2013 by Facebook. Over the years, it has passed through several major versions:

2015: React 0.14 was introduced with functional components.

2016: React 15 was designed to improve performance, and so was the implementation of the Fiber architecture.

2017: React 16 brought in Hooks and Error Boundaries.

2020: React 17 emphasized easier upgrades and gradual adoption.

2022+: React 18 introduced concurrent rendering with automatic batching.

Why to Learn React.js by 2025?

Performance and Speed

With fast UI updates made possible by the React Virtual DOM and concurrent rendering, React will be an indispensable framework for modern applications.

Large Community Support

React has a vast user base consisting of millions of developers, and thus, finding resources, tutorials, and support is easier than before.

Flexibility and Scalability

Applications of any size can be developed using React, whether they are small projects or enterprise-level applications.

Core Features of React.js

Virtual DOM

In React, unlike in the normal DOM, only those parts of the UI that were actually changed would be updated, thereby giving faster performance.

Component-Based Architecture

In React, an application is made up of building blocks called components, which are reusable, thereby minimizing redundancy.

JSX (JavaScript XML)

JSX enables developers to write markup directly inside the code.

One-Way Data Binding

This aids in keeping tighter control over the data flow, which is beneficial for easier debugging.

Setting Up React.js in 2025

Install Node.js and npm.

Create a React app using:

npx create-react-app my-app

cd my-app

npm start

Use Vite for faster builds:

npm create vite@latest my-app --template react

Building a Basic React.js Application

Creating Components

function Welcome(props) {

  return <h1>Hello, {props.name}!</h1>;

}

Using State with Hooks

import { useState } from 'react';

function Counter() {

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

  return (

    <button onClick={() => setCount(count + 1)}>

      Count: {count}

    </button>

  );

}

React.js Best Practices for 2025

Functional components are preferred over class components.

Keep components small and reusable.

Render optimization through memoization (React.memo, useMemo).

Follow proper folder structures.

Error boundaries should be implemented.

HEIC (High-Efficiency Image Format) is a popular image format used by Apple devices, offering high-quality images with smaller file sizes compared to JPEG. However, this format is not universally supported, which might necessitate converting HEIC images to a more accessible format like PDF. In this article, we'll explore how to convert HEIC images to PDF using JavaScript Node.js. A working example of this tool is available on this page . Prerequisites To follow along with this tutorial, you'll need: Basic knowledge of JavaScript and Node.js. Node.js installed on your system. Familiarity with npm (Node Package Manager). Step-by-Step Guide Step 1: Set Up Your Project First, create a new directory for your project and initialize it with npm. mkdir heic-to-pdf cd heic-to-pdf npm init -y Step 2: Install Required Packages We'll use the following npm packages: heic-convert to convert HEIC images to PNG. pdf-lib to create PDF documents. Install these packages by running: npm install heic-convert pdf-lib Step 3: Write the Conversion Script Create a new JavaScript file, convert.js, in your project directory. This script will handle the conversion process. const fs = require('fs'); const heicConvert = require('heic-convert'); const PDFDocument = require('pdf-lib'); async function convertHeicToPdf(inputPath, outputPath) // Read the HEIC file const heicBuffer = fs.readFileSync(inputPath); // Convert HEIC to PNG const pngBuffer = await heicConvert( buffer: heicBuffer, format: 'PNG', quality: 1 // Set quality to 1 (highest) ); // Create a new PDF document const pdfDoc = await PDFDocument.create(); // Embed the PNG image into the PDF const pngImage = await pdfDoc.embedPng(pngBuffer); const pngDims = pngImage.scale(1); // Add a blank page and draw the PNG image on it const page = pdfDoc.addPage([pngDims.width, pngDims.height]); page.drawImage(pngImage, x: 0, y: 0, width: pngDims.width, height: pngDims.height ); // Serialize the PDF document to bytes (a Uint8Array) const pdfBytes = await pdfDoc.save(); // Write the PDF to a file fs.writeFileSync(outputPath, pdfBytes); console.log(`Converted HEIC to PDF: $outputPath`); Example Usage of the function // Example usage convertHeicToPdf('input.heic', 'output.pdf'); Running the Script To convert a HEIC image to a PDF, run the following command: node convert.js Ensure you have an input.heic file in your project directory. The script will generate an output.pdf file in the same directory. Conclusion Converting HEIC images to PDF using JavaScript is straightforward with the help of heic-convert and pdf-lib. This solution reads a HEIC file, converts it to a PNG image, embeds the PNG into a PDF document, and saves the PDF file. This approach can be extended and integrated into larger applications, providing a practical solution for handling HEIC images in a more accessible format. With this method, you can efficiently convert HEIC images to PDF, making them easier to share and view across different devices and platforms.
