Building a feature-rich web application often requires simple yet effective solutions. One such example is managing uploaded images in memory, specifically camera screenshots. Here, I’ll walk you through how to create an Express.js endpoint that stores and retrieves screenshots from memory. This setup is ideal when you want lightweight, temporary storage for uploaded files without
Building a seamless connection between a TypeScript application and a C# application can feel like bridging two worlds. Both languages have strong typing capabilities, but ensuring that they adhere to the same contract can be challenging. In my experience, the best approach is to define a shared schema that governs the data structures and enforce
Testing is one of those steps in software development that separates a hobby project from a professional one. Whether you’re building something small or maintaining a complex codebase, testing ensures your code does what it’s supposed to do. If you’re new to testing in Python, pytest is one of the easiest tools to get started
One of the most exciting moments in a development project is sharing your work with others. If you’re building an app with Socket.IO, whether for real-time messaging, notifications, or interactive applications, you’ll eventually want to make your local setup accessible to the public. This allows collaborators, testers, or clients to interact with your app without
Have you ever run into the frustrating problem of your script not finding the file it’s supposed to read? I know I have, especially when moving a project between environments or sharing it with a teammate. One key lesson I’ve learned is to always rely on relative paths that adapt to the script’s location. This
When I first stumbled upon the need to show differences between strings in a Git-like format, I wasn’t sure where to start. The idea seemed daunting—how could I highlight additions, removals, and changes in a clear, color-coded way? Luckily, Python’s difflib module came to the rescue. What started as a challenge turned into a rewarding
When I first started working with Python, one of the most common tasks I encountered was searching for a specific string in a list (or array) of strings. Whether it was looking up a username, checking for keywords, or validating input, this task came up over and over again. Thankfully, Python offers several easy and
Building a seamless connection between a TypeScript application and a Java application can feel like bridging two worlds. Both languages have strong typing capabilities, but ensuring that they adhere to the same contract can be challenging. In my experience, the best approach is to define a shared schema that governs the data structures and enforce
Working with data in Python often means dealing with various file formats, and JSONL (JSON Lines) is one of the most practical for handling structured data in bulk. If you’ve come across this format and wondered how to read it efficiently, you’re in the right place. JSONL files are a series of JSON objects, each
When I started working on a live QR code scanner in React, I wanted to create something that not only displayed a webcam feed but also scanned and decoded QR codes in real time. With React, TypeScript, and a few powerful libraries, it turned out to be an engaging and surprisingly manageable task. Using react-webcam
Creating a camera preview in an Android application might sound like a daunting task, but it’s a rewarding journey that lets you interact directly with hardware. In this post, I’ll guide you through building an app that shows your camera feed on the screen using the Camera2 API and Kotlin. Along the way, I’ll share
When I first started working with Docker, one of the things I needed to figure out was how to run a Python script efficiently within a container. Docker is a fantastic tool for containerizing applications, and running Python scripts in this environment can simplify dependencies and make your projects more portable. In this post, I’ll
