debugging

When it comes to programming, it’s often necessary to test and experiment with code quickly. While it’s easy to debug client-side code using Chrome DevTools, debugging Node.js code with access to the filesystem and other Node.js capabilities might seem a bit challenging. However, it’s actually quite simple. To debug a Node.js app using Chrome DevTools, follow these steps: Open your terminal and run the following command: node --inspect This will start the Node....

Debugging is an essential part of the development process, and having a reliable and efficient code editor is crucial. One of the best code editors out there is Visual Studio Code (VS Code) by Microsoft. Its speed, stability, and extensibility make it an ideal choice for developers. If you’re a Go developer using VS Code, you might be wondering how to debug your Go programs. Fortunately, it’s super easy with Delve, a powerful debugger made specifically for Go by Derek Parker....

Debugging is an essential skill for programmers to overcome challenging situations and improve code efficiency. In Python, the built-in debugger pdb is available in the standard library, enabling developers to easily identify and fix errors. In this blog post, we will explore the key features of pdb and how to utilize it effectively in your Python projects. To start debugging your code, you can add breakpoints at specific locations using the breakpoint() function....

When it comes to debugging a React application, there are a few tools that can help you identify and solve problems. In this blog post, I will discuss some of these tools and how you can use them effectively. One of the best tools available for debugging React applications is the React Developer Tools. This browser extension allows you to inspect and analyze React apps with ease. If you are interested in learning more about this tool, I highly recommend checking out my dedicated blog post on React Developer Tools....

In this tutorial, we will discuss how to disable specific ESLint rules in your code. Sometimes, your tooling may automatically set certain ESLint rules, such as the no-debugger and no-console rules. While these rules may be useful for production code, they can be restrictive during development when you need to access the browser debugger and the Console API. To disable these rules, you have several options: Disabling Rules for a Whole File To disable one or more specific ESLint rules for an entire file, you can add the following comment at the top of the file:...

If you’ve encountered the following error in your Next.js codebase or any JavaScript codebase: TypeError: Attempted to assign to readonly property Don’t worry! This error is not specific to Next.js and can occur in any JavaScript project. After some debugging, I discovered that the issue was related to a database column where I stored data as JSON. The problem arose when I tried to update this JSON object using dot syntax (e....

When writing JavaScript, some developers prefer not to use semicolons for a cleaner code. However, there are situations where we need to be careful, especially when using the require() function in Node.js to load external modules and files. In certain cases, you may encounter an error like this: TypeError: require(...) is not a function This error can be a bit confusing. Let’s go over how this error can occur. For example, let’s say you require a library and then need to execute some code at the root level using an immediately-invoked async function:...

Netcat is a powerful Unix command that allows you to perform various networking tasks. It is often used for debugging purposes and to gain a deeper understanding of how things work. Netcat, also known as nc, is readily available on Unix systems. To connect to a network server using Netcat, use the following syntax: nc DOMAIN PORT For example, to connect to the localhost on port 8000, you can use:...

Alert messages are a useful way to provide feedback to users and aid in debugging applications. In SwiftUI, you can leverage the .alert() modifier to display alerts based on certain conditions. Let’s consider an example where we have a Button with an associated counter: import SwiftUI struct ContentView: View { @State var count = 0 var body: some View { Button("Count: \(count)") { self.count += 1 } .font(.title) } } Suppose we want to show an alert message when the count reaches 10....

Curl is a command-line tool that allows you to transfer data across the network. It supports a wide range of protocols, including HTTP, HTTPS, FTP, FTPS, SFTP, IMAP, SMTP, POP3, and more. This tool is extremely useful for debugging network requests and is considered a programmer’s best friend. Installing Curl Curl is a universal tool that can be installed on Linux, Mac, and Windows. You can refer to the official installation guide to install it on your system....
