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
Building components in React is always a rewarding experience, especially when the result is sleek, reusable, and visually impressive. Today, I’ll walk you through creating a progress bar in React that is always 100% wide, with a dynamic background that visually represents progress through a transparent effect on the right. We’ll use CSS and TypeScript
As a developer, I often find myself needing to generate realistic-looking data for testing purposes. One common requirement is creating phone numbers that mimic real-world formats. For example, in the United States, phone numbers often follow the 999-999-9999 pattern. This is where the Faker library shines—it allows you to generate fake yet convincing data with
Apache Flink is a powerful tool for processing data streams, but setting it up locally can sometimes feel like an uphill task. As someone who appreciates a smooth development workflow, I’ve found that using Docker simplifies the process immensely. In this post, I’ll walk you through setting up Flink locally using Docker Compose, troubleshooting potential
When developing and testing applications that rely on Azure Event Hubs, it’s incredibly convenient to have a local setup. While Azure Event Hubs itself cannot run locally, we can emulate it using a combination of tools like Azurite for Azure Storage and Kafka for event streaming. This setup allows us to test our event-driven applications
Bluetooth Low Energy (BLE) has revolutionized how devices communicate wirelessly, enabling lightweight, low-power connectivity. If you’re diving into BLE with Node.js, understanding how to scan BLE advertisements is essential. I recently tackled this challenge using the @abandonware/noble library and TypeScript, and I want to share the process, step by step. What is BLE (Bluetooth Low
When running a production-grade React application served by Nginx, maintenance mode becomes a handy tool for planned downtime. I recently implemented maintenance mode for a Vite-powered React app and learned a lot about how to make it efficient and dynamic. Here, I’ll share the steps to set it up so that your app checks for
Managing application settings is critical for modern applications, especially when your app needs to adapt dynamically to changes without redeployment. In this blog post, I’ll share how you can use Azure App Configuration in a .NET application to keep your configuration fresh, reliable, and responsive to change. When working with Azure App Configuration, you can
