XHR/fetch breakpoints are a type of breakpoint available in modern browser developer tools like Chrome DevTools, Firefox Developer Tools, and Microsoft Edge DevTools. They allow you to pause code execution specifically when an XHR (XMLHttpRequest) or Fetch API request occurs . This is incredibly useful for debugging and analyzing network traffic related to your web application. Here's what you need to know about XHR/fetch breakpoints: Triggering Conditions: These breakpoints trigger based on the URL of the request . You can specify a full URL, part of the URL (e.g., using wildcards), or even regular expressions to match specific patterns. Some tools might also offer options to break on specific HTTP methods (GET, POST, etc.) or request types (main request, sub-requests). Benefits: Pinpointing network issues: Use them to identify slow or failed requests, analyze response data, and debug API calls. Understanding request flow: See the order and timing of multiple requests made by yo...

Alternate titles for this article: Unleashing Parallel Power: A Tour of Web Workers, Shared Workers, and More Beyond the Main Thread: How Worker Technologies Transform Web Development Mastering Multithreading: A Guide to Leveraging Worker Technologies in JavaScript Worker technologies in web development offer powerful ways to run JavaScript in the background, separate from the main page thread. This parallelism improves performance, responsiveness, and allows for handling long-running tasks without blocking the main UI. Here are some key worker technologies: 1. Web Workers: Most common option, enabling separate script execution in parallel with the main page. Communicate with the main page through postMessage for asynchronous data exchange. Suitable for computationally intensive tasks, background processes, and long-running operations like image processing or video encoding. 2. Shared Workers: Multiple pages within the same domain can share a single Shared Worker instance. Useful for t...

In CSS, layout modes define how various elements are positioned and arranged on the webpage. Several different layout modes exist, each with its own strengths and weaknesses. Here's a breakdown of the most common ones: 1. Normal Flow: This is the default layout mode for all elements. Elements stack vertically, one after the other, based on the document's flow. Block elements (like paragraphs and headings) occupy the full width of their container, while inline elements (like text and images) flow along the same line. Offers control over element sizes and margins but can be inflexible for complex layouts. 2. Floats: Allows elements to "float" to the left or right of the text flow. Useful for creating sidebars, wrapping text around images, or other basic layout adjustments. Can be tricky to manage and lead to overlapping content or layout instability. 3. Positioning: Offers precise control over the position of elements on the page. You can specify exact coordinates...

Hey everyone, and welcome to my blog! I'm going to be sharing with you the top 10 Telegram hidden features you might not know about,  Telegram is a popular messaging app that's known for its speed, security, and features. But even if you're a longtime Telegram user, there are probably a few features you're unaware of.

This is great for sending messages to people in different time zones or when you don't want to disturb them. To schedule a message, simply type out your message and then long-press on the send button. This will give you the option to schedule the message for a later time. To send a silent message, simply type out your message, then long-press on the send button, then select the option of “Send without sound”. This will send the message without making a notification sound on the recipient's device. Feature 2: Cu...

Nodemon is a development tool that is used to automatically restart your Node.js application when it detects changes to your code. You do not need to have Nodemon installed in production, as your application will be running continuously. To install Nodemon as a development dependency, simply open a terminal window and navigate to the directory of your project and run  one of the following commands: npm install --save-dev nodemon OR npm i -D nodemon This will install Nodemon and add it to your project's devDependencies section in the package.json file. This means that Nodemon will only be installed in your project's node_modules directory if you are using a package manager, such as npm or Yarn. It will not be installed if you are deploying your project to production. Once Nodemon is installed, you can start your Node.js application in development mode by running the following command: nodemon This will start Nodemon and watch for changes to your application files. When it det...
