Recently, while working on a project, I needed to create a chat feature with a UI similar to iMessage. When I reached the part where I had to implement the curls, I considered three options: One: Use before and after pseudo element. (Challenge: pseudo classes and element do not work in react-native, hence option 2) Two: Use two Views one for the curl and another to overlap it. Something like this <View style={styles.chatBubble}> <Text style={styles.text}> Hey whats up </Text> <View style={styles.curl}></View> <View style={styles.curlOverlap}></View> </View> Enter fullscreen mode Exit fullscreen mode Three: Use an Svg. Less work :) yay! Initially, I…

What is Threads and its use in Node.js

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, node, programming, software, webdev

In the bustling world of computer science, threads are like tiny, independent workers within a larger workshop, a process. Imagine a single process as a factory. This factory has various tasks to complete, from assembling parts to running quality checks. Threads, on the other hand, are the individual workers on the assembly line. They share the same resources (tools, materials) within the factory (process) but can work on different tasks (instructions) concurrently. What are Threads? Threads are lightweight units of execution within a process. They share the same memory space and resources (like CPU time) of the process they belong…

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, javascript, react, software, webdev

Introduction In the world of front-end development, creating user interfaces (UI) that are flexible, maintainable, and scalable is crucial. One approach that helps achieve these goals is the concept of a config-driven UI. This blog will introduce you to config-driven UI, explain its benefits, and provide simple examples to help you understand how it works. What is Config-Driven UI? Config-driven UI is a design pattern where the structure and behaviour of the user interface are defined using configuration files rather than hard-coded in the application. These configuration files are typically in formats like JSON or YAML. By separating the UI…

Seamless State Management using Async Iterators

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, node, software, webdev

In my recent post about AI-UI, I touched on why I developed the library. I wanted declarative markup I wanted type-safe component encapsulation, with composition & inheritance I wanted a small, fast client-side solution with no complex build process (or any build process!) ...but most importantly... I didn't want to learn a whole new API just to manipulate data I already have in my app In my single page apps, I've got remote APIs and endpoints that supply data. Sure, I might want to do a bit of arithmetic, sorting, formatting, but basically, I want to say to the UI:…
