Convert HTML to Image: A Step-by-Step Guide ✨

Do you want to turn some HTML code you've made that's on your website and have a way to convert it into an image for you to save?

Well, look no further! I too wanted to do the same thing but funny enough, there weren't any straightforward tutorials out there that could show you how! After hours of searching, I finally discovered the solution~!

This is an old tutorial I made 🐼

💛 Set your environment

Before we dive into the conversion process, I'll assume you already have your HTML code ready. What you want to learn is how to turn it into an image file. You should have a good grasp of HTML and JavaScript. For this tutorial, we'll use the following HTML code example:

We won't include the CSS code, as it doesn't affect this tutorial. The JavaScript file (script.js) at the bottom of the body element is where we'll add the functionality for the conversion.

Your page should resemble the following:

As you can see, the "Click me" button will handle the conversion. We aim to convert everything within the div.info-div into an image.

💛 Using the html2canvas JavaScript Library

The html2canvas library allows you to take screenshots of webpages and target specific elements on a screen. Here are the steps to include the library in your project:

The steps to put the library in your project:

Visit the html2canvas website for more information.

Copy the CDN link from here

and include it in a script tag in your project's head tag in the HTML file:

That's it for including the library on the HTML side. Now, let's move on to the JavaScript code.

💛 JavaScript Functionality

Here's the JavaScript code to handle the conversion:

In this code, I want to turn the whole div.info-div into an image, I put it into a variable in const div = document.querySelector(".info-div");.

I also put the button into a variable in const button = document.querySelector("button");

I added a click event listener to the button so when the user clicks the button, it will follow the code inside of the event listener!

You can find similar code like this in the documentation of the html2canvas library:

What is happening here is:

We add the div (or what the element we want to take an image of) into the html2canvas([element]).then((canvas)

Added the image file type url to a variable = const imageDataURL = canvas.toDataURL("image/png"); - You can replace the png to other image file types such as jpg, jpeg etc

Created an anchor/link tag, added the href attribute to imageDataURL

The download attribute is where we will give the default name to the image file, I added "dog.png"

Perform the click() function to the anchor tag so it starts to download the image we created

And that's it!

💛 The End

And that's it! You've successfully learned how to turn your HTML into an image. It's a great way to save and share your web content in a unique format.

If you have any questions or need further clarification, please comfortable to ask. Enjoy converting your HTML into images! 💖🐼

Learn how to code the object pool pattern by pre-allocating memory and reusing objects. Which can greatly improve performance when reusing short lived objects like bullets and particles.

This tutorial will show you how to create and manage a pool of bullet objects. For example, this is useful in shooter and bullet hell games which have thousands of bullets on the screen.

The tutorial is written in the Java programming language, and uses the free Processing graphics library and integrated development environment.

The object pool pattern can be especially useful with programming languages which use automatic garbage collection like Java, C#, JavaScript, Python, etc.

Since automatic garbage collection can stall your program and reduce your frame rates. The object pool pattern gives you more control over when the garbage collector comes to reclaim the memory.

The downside of the object pool pattern is that it complicates the life cycle of the object. Meaning you need to reset the variables of the object before you can reuse it. Since its variables are unlikely to match the defaults after repeated use.

There are a few ways to implement the object pool pattern, this tutorial will show you one method.

JavaScript Frameworks

Step 1) Polyfill

Most JS frameworks started from a need to create polyfills. A Polyfill is a js script that add features to JavaScript that you expect to be standard across all web browsers. Before the modern era; browsers lacked standardization for many different features between HTML/JS/and CSS (and still do a bit if you're on the bleeding edge of the W3 standards)

Polyfill was how you ensured certain functions were available AND worked the same between browsers.

JQuery is an early Polyfill tool with a lot of extra features added that makes JS quicker and easier to type, and is still in use in most every website to date. This is the core standard of frameworks these days, but many are unhappy with it due to performance reasons AND because plain JS has incorporated many features that were once unique to JQuery.

JQuery still edges out, because of the very small amount of typing used to write a JQuery app vs plain JS; which saves on time and bandwidth for small-scale applications.

Many other frameworks even use JQuery as a base library.

Step 2) Encapsulated DOM

Storing data on an element Node starts becoming an issue when you're dealing with multiple elements simultaneously, and need to store data as close as possible to the DOMNode you just grabbed from your HTML, and probably don't want to have to search for it again.

Encapsulation allows you to store your data in an object right next to your element so they're not so far apart.

HTML added the "data-attributes" feature, but that's more of "loading off the hard drive instead of the Memory" situation, where it's convenient, but slow if you need to do it multiple times.

Encapsulation also allows for promise style coding, and functional coding. I forgot the exact terminology used,but it's where your scripting is designed around calling many different functions back-to-back instead of manipulating variables and doing loops manually.

Step 3) Optimization

Many frameworks do a lot of heavy lifting when it comes to caching frequently used DOM calls, among other data tools, DOM traversal, and provides standardization for commonly used programming patterns so that you don't have to learn a new one Everytime you join a new project. (you will still have to learn a new one if you join a new project.)

These optimizations are to reduce reflowing/redrawing the page, and to reduce the plain JS calls that are performance reductive. A lot of these optimatizations done, however, I would suspect should just be built into the core JS engine.

(Yes I know it's vanilla JS, I don't know why plain is synonymous with Vanilla, but it feels weird to use vanilla instead of plain.)

Step 4) Custom Element and component development

This was a tool to put XML tags or custom HTML tags on Page that used specific rules to create controls that weren't inherent to the HTML standard. It also helped linked multiple input and other data components together so that the data is centrally located and easy to send from page to page or page to server.

Step 5) Back-end development

This actually started with frameworks like PHP, ASP, JSP, and eventually resulted in Node.JS. these were ways to dynamically generate a webpage on the server in order to host it to the user. (I have not seen a truly dynamic webpage to this day, however, and I suspect a lot of the optimization work is actually being lost simply by programmers being over reliant on frameworks doing the work for them. I have made this mistake. That's how I know.)

The backend then becomes disjointed from front-end development because of the multitude of different languages, hence Node.JS. which creates a way to do server-side scripting in the same JavaScript that front-end developers were more familiar with.

React.JS and Angular 2.0 are more of back end frameworks used to generate dynamic web-page without relying on the User environment to perform secure transactions.

Step 6) use "Framework" as a catch-all while meaning none of these;

Polyfill isn't really needed as much anymore unless your target demographic is an impoverished nation using hack-ware and windows 95 PCs. (And even then, they could possible install Linux which can use modern lightweight browsers...)

Encapsulation is still needed, as well as libraries that perform commonly used calculations and tasks, I would argue that libraries aren't going anywhere. I would also argue that some frameworks are just bloat ware.

One Framework I was researching ( I won't name names here) was simply a remapping of commands from a Canvas Context to an encapsulated element, and nothing more. There was literally more comments than code. And by more comments, I mean several pages of documentation per 3 lines of code.

Custom Components go hand in hand with encapsulation, but I suspect that there's a bit more than is necessary with these pieces of frameworks, especially on the front end. Tho... If it saves a lot of repetition, who am I to complain?

Back-end development is where things get hairy, everything communicates through HTTP and on the front end the AJAX interface. On the back end? There's two ways data is given, either through a non-html returning web call, *or* through functions that do a lot of heavy lifting for you already.

Which obfuscates how the data is used.

But I haven't really found a bad use of either method. But again; I suspect many things about performance impacts that I can't prove. Specifically because the tools in use are already widely accepted and used.

But since I'm a lightweight reductionist when it comes to coding. (Except when I'm not because use-cases exist) I can't help but think most every framework work, both front-end and Back-end suffers from a lot of bloat.

And that bloat makes it hard to select which framework would be the match for the project you're working on. And because of that; you could find yourself at the tail end of a development cycle realizing; You're going to have to maintain this as is, in the exact wrong solution that does not fit the scope of the project in anyway.

Well. That's what junior developers are for anyway...

GitHub Repositories Hit by Password-Stealing Commits Disguised as Dependabot Contributions

A new deceptive campaign has been observed hijacking GitHub accounts and committing malicious code disguised as Dependabot contributions with an aim to steal passwords from developers.

"The malicious code exfiltrates the GitHub project's defined secrets to a malicious C2 server and modify any existing javascript files in the attacked project with a web-form password-stealer malware code effecting any end-user submitting its password in a web form," Checkmarx said in a technical report

The malware is also designed to capture GitHub secrets and variables to a remote server by means of a GitHub Action.

The software supply chain security firm said it observed the atypical commits to hundreds of public and private GitHub repositories between July 8 and 11, 2023.

It has emerged that the victims had their GitHub personal access tokens stolen and used by the threat actors to make falsified code commits to users' repositories by posing as Dependabot.

Dependabot is designed to alert users of security vulnerabilities in a project's dependencies by automatically generating pull requests to keep them up-to-date.

"The attackers accessed the accounts using compromised PATs (Personal Access Token) -- most likely exfiltrated silently from the victim's development environment," the company said. Most compromised users are located in Indonesia.

However, the exact method by which this theft may have taken place is currently unclear, although it's suspected that it may have involved a rogue package inadvertently installed by the developers.

This is evidenced by a new data exfiltration campaign targeting both npm and PyPI that uses as many as 39 counterfeit packages to gather sensitive machine information and transmit the details to a remote server.

The development highlights the continued attempts on part of threat actors to poison open-source ecosystems and facilitate supply chain compromises.

JavaScript 17 🧬 closure

New Post has been published on https://tuts.kandz.me/javascript-17-%f0%9f%a7%ac-closure/

JavaScript 17 🧬 closure

a - closure intro closure is a function that retains access to its lexical scope, even when the function is executed outside of that scope. This means that a closure can "remember" and access variables from the environment in which it was created... even after that environment has finished executing. Key Concepts: 1. Lexical Scope: Lexical scope refers to the way variables are scoped according to their location in the code, rather than when they are called. A function's lexical environment is determined by where it was defined, not where it was executed. 2. Execution Context: The execution context is the environment in which JavaScript code executes. It includes the variable and function declarations that are currently accessible. 3. Closure Creation: *When a function is created inside another function, the inner function retains access to the variables of the outer function's scope. Common Misconceptions: Closures Capture Values, Not References → When a closure captures a variable, it captures the value of that variable at the time the closure was created. Changes to the original variable after the closure is created do not affect the closure. In conclusion they enable encapsulation, data hiding, and state management, making them an essential tool for any JavaScript developer. b - closure examples 1. Function Definition → createCounter is defined with a local variable count initialized to 0. Inside createCounter, another function (an anonymous function) is defined and returned. 2. Closure Creation → When createCounter is called, it returns the inner function. This inner function retains access to the count variable from its lexical scope (createCounter). 3. Usage of Closure: The returned inner function (closure) is stored in the counter variable. Each time counter() is called, it increments and logs the count variable. Use Cases for Closures: Encapsulation and Data Hiding → You can use closures to create private variables that cannot be accessed from outside the function. Factory Functions: Closures are often used to create factory functions, which generate objects with specific behavior. Maintaining State Across Asynchronous Operations: Closures can help maintain state in asynchronous operations by retaining access to variables.

Top 10 Challenges in Automation Testing and Their Solutions (with Genqe.ai)

Automation testing is a cornerstone of modern software development. It enables rapid feedback, improved accuracy, and faster release cycles. However, implementing automation isn’t without its hurdles. From script maintenance to tool compatibility and scaling, QA teams encounter various obstacles that can slow down progress and inflate costs.

In this article, we explore the top 10 challenges in automation testing, their real-world implications, and how to solve them effectively — especially using intelligent platforms like Genqe.ai, which leverages generative AI to streamline and simplify automation.

Challenge 1: High Initial Investment and Tool Selection

The Problem: Automation testing often requires upfront investment in tools, infrastructure, and training. Choosing the wrong tool can lead to wasted resources and stalled progress.

The Solution: Start with a clear understanding of your application environment, technology stack, and team capabilities. Opt for tools that support cross-platform testing and integrate well with your CI/CD pipeline. With Genqe.ai, teams eliminate the need for complex scripting tools. It allows test creation in plain English, reducing the learning curve and upfront tool complexity.

Challenge 2: Difficulty in Identifying What to Automate

The Problem: Automating every test case is impractical and costly. Teams struggle to identify high-priority test cases that should be automated first.

The Solution: Use a risk-based approach. Automate high-frequency and high-risk functionalities such as login flows, payment systems, and API integrations. Genqe.ai assists with test case prioritization by analyzing application logic and suggesting critical paths that yield maximum coverage with minimal effort.

Challenge 3: Frequent UI Changes Break Tests

The Problem: UI-driven automation is fragile. Even minor UI changes — like button renaming or layout shifts — can cause test scripts to fail.

The Solution: Implement a test automation platform that supports self-healing mechanisms to adapt to UI changes. Genqe.ai automatically updates test scripts using AI-driven pattern recognition. When it detects a UI change, it intelligently adjusts the locator or flow, keeping the test valid without manual intervention.

Challenge 4: Script Maintenance Overhead

The Problem: As applications evolve, maintaining scripts becomes a full-time job. QA teams are often stuck updating old scripts instead of writing new ones.

The Solution: Adopt modular, reusable components for test scripts and avoid hard-coded values. Genqe.ai simplifies this through smart script generation and maintenance. It detects outdated flows and suggests optimizations or updates based on new application behavior — cutting maintenance time drastically.

Challenge 5: Test Data Management

The Problem: Reliable test data is essential for consistent results. However, managing, generating, and maintaining test data for different environments is complex.

The Solution: Use automated data generation tools or integrate your automation platform with data provisioning systems. Genqe.ai supports dynamic data handling, allowing users to define variables in plain language and enabling the tool to fetch or generate relevant test data for different scenarios.

Challenge 6: Lack of Skilled Resources

The Problem: Not every QA team has deep technical expertise. Traditional tools often require knowledge of scripting languages like Java, Python, or JavaScript.

The Solution: Choose no-code or low-code platforms that empower testers without requiring programming knowledge. With Genqe.ai, test cases can be created using natural language prompts. Even non-technical team members can contribute to automation, significantly expanding team capacity.

Challenge 7: Integration with CI/CD Pipelines

The Problem: Automation tools that operate in isolation are less effective. If they don’t integrate with Jenkins, GitLab, Azure DevOps, or other CI/CD tools, automation becomes a bottleneck.

The Solution: Select automation solutions that support API-based or native integrations with DevOps pipelines. Genqe.ai is designed with CI/CD integration in mind, offering plug-and-play compatibility with popular tools. It enables continuous testing as part of your deployment pipeline, ensuring timely feedback for every code change.

Challenge 8: Limited Test Coverage

The Problem: Teams often automate only UI or functional tests, leaving out performance, security, or edge-case testing. This leads to false confidence and missed bugs.

The Solution: Adopt a layered testing strategy that includes unit, integration, performance, and end-to-end testing. Genqe.ai expands testing scope with AI-driven suggestions that cover not just the happy paths but also edge cases and rare failure scenarios. It ensures your coverage is holistic, not just superficial.

Challenge 9: Cross-Browser and Cross-Device Testing

The Problem: With the explosion of devices, browsers, and screen sizes, ensuring consistent behavior across environments is daunting.

The Solution: Use cloud-based platforms or automation tools that allow test execution across multiple devices and configurations. Genqe.ai supports cross-platform automation. You can write a single test in natural language and execute it across different devices and browsers, ensuring uniform performance without duplicating test efforts.

Challenge 10: Inadequate Reporting and Debugging

The Problem: When tests fail, poor reporting makes it hard to trace the issue. Debugging becomes time-consuming and frustrating.

The Solution: Look for tools that offer detailed logs, visual reports, and actionable feedback. Genqe.ai excels in this area by providing AI-generated insights, visual step-by-step breakdowns, and natural language explanations of what went wrong. This accelerates root cause analysis and helps teams respond quickly to issues.

Why Choose Genqe.ai for Automation Testing

Start Coding Today: Learn React JS for Beginners

Start Coding Today: Learn React JS for Beginners”—will give you a solid foundation and guide you step by step toward becoming a confident React developer.

React JS, developed by Facebook, is an open-source JavaScript library used to build user interfaces, especially for single-page applications (SPAs). Unlike traditional JavaScript or jQuery, React follows a component-based architecture, making the code easier to manage, scale, and debug. With React, you can break complex UIs into small, reusable pieces called components.

Why Learn React JS?

Before diving into the how-to, let’s understand why learning React JS is a smart choice for beginners:

High Demand: React developers are in high demand in tech companies worldwide.

Easy to Learn: If you know basic HTML, CSS, and JavaScript, you can quickly get started with React.

Reusable Components: Build and reuse UI blocks easily across your project.

Strong Community Support: Tons of tutorials, open-source tools, and documentation are available.

Backed by Facebook: React is regularly updated and widely used in real-world applications (Facebook, Instagram, Netflix, Airbnb).

Prerequisites Before You Start

React is based on JavaScript, so a beginner should have:

Basic knowledge of HTML and CSS

Familiarity with JavaScript fundamentals such as variables, functions, arrays, and objects

Understanding of ES6+ features like let, const, arrow functions, destructuring, and modules

Don’t worry if you’re not perfect at JavaScript yet. You can still start learning React and improve your skills as you go.

Setting Up the React Development Environment

There are a few ways to set up your React project, but the easiest way for beginners is using Create React App, a boilerplate provided by the React team.

Step 1: Install Node.js and npm

Download and install Node.js from https://nodejs.org. npm (Node Package Manager) comes bundled with it.

Step 2: Install Create React App

Open your terminal or command prompt and run:

create-react-app my-first-react-app

This command creates a new folder with all the necessary files and dependencies.

Step 3: Start the Development Server

Navigate to your app folder:

my-first-react-app

Then start the app:

Your first React application will launch in your browser at http://localhost:3000.

Understanding the Basics of React

Now that you have your environment set up, let’s understand key React concepts:

1. Components

React apps are made up of components. Each component is a JavaScript function or class that returns HTML (JSX).

function Welcome() { return <h1>Hello, React Beginner!</h1>; }

2. JSX (JavaScript XML)

JSX lets you write HTML inside JavaScript. It’s not mandatory, but it makes code easier to write and understand.

const element = <h1>Hello, World!</h1>;

3. Props

Props (short for properties) allow you to pass data from one component to another.

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

4. State

State lets you track and manage data within a component.

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> ); }

Building Your First React App

Let’s create a simple React app — a counter.

Open the App.js file.

Replace the existing code with the following:

import React, { useState } from 'react'; function App() { const [count, setCount] = useState(0); return ( <div style={{ textAlign: 'center', marginTop: '50px' }}> <h1>Simple Counter App</h1> <p>You clicked {count} times</p> <button onClick={() => setCount(count + 1)}>Click Me</button> </div> ); } export default App;

Save the file, and see your app live on the browser.

Congratulations—you’ve just built your first interactive React app!

Where to Go Next?

After mastering the basics, explore the following:

React Router: For navigation between pages

useEffect Hook: For side effects like API calls

Forms and Input Handling

API Integration using fetch or axios

Styling (CSS Modules, Styled Components, Tailwind CSS)

Context API or Redux for state management

Deploying your app on platforms like Netlify or Vercel
