The Death of Server-Side Uploads? A Frontend Guide to Direct-to-Cloud Uploads in React

A 100 MB upload through your API server holds a connection, memory, and a worker for the whole transfer. With a few users uploading at once, your app feels slow even though nothing is wrong with your code. The common fix is to let the browser send the file straight to cloud storage (S3, Cloudflare R2, and similar). The backend stops carrying the bytes and only decides who may upload what. This post covers the frontend side of that flow: browser APIs, a React implementation, progress, cancellatio

The Small Emoji Problem in Web Development That Takes More Time Than It Should

Have you ever needed an emoji for a project, only to spend the next few minutes looking for the right version? Sometimes you just need a PNG for your UI. Other times, you need an SVG, a Unicode value, an HTML entity, or an encoded version. And somehow, finding all of these can mean opening multiple websites just to get one little thing. It's not a big problem, but it's the kind of small task that interrupts your workflow, especially when you're already juggling design and development work. We wa

Prop Drilling in React

In React, props are used to pass data from a parent component to a child component. Props are an important part of React because they allow components to share information. However, when data needs to travel through many levels of components, it can lead to a situation called Prop Drilling. Prop drilling means passing data from a parent component to a deeply nested child component through intermediate components, even when those intermediate components do not need the data. For example, imagine

React useState Basics: Build Dynamic UI with Vite

React apps look like normal HTML pages, but they behave differently. When a user clicks a button, types in an input, selects a checkbox, or changes a dropdown, the UI should update immediately. That is why we use state in React. useState stores changing data inside a component. When we call its setter function—for example setCount, setUser, or setForm—React saves the next value, renders the component again, and updates only the required UI parts. State updates are applied for the next render, so

useState in React

When building interactive web applications with React, we often need to store values that can change over time. For example, a counter value can increase, a user's name can change, or a login status can switch between logged in and logged out. React provides a Hook called useState to handle these changing values. useState is a React Hook that allows functional components to create and manage state. State is a value that a component needs to remember between renders. When the state changes, React

One React/Vite product across PWA and Tauri—without pretending they are identical

One React/Vite codebase can power a GitHub Pages site, an installed PWA, an edge-hosted deployment, and a Tauri desktop app. That does not make those surfaces interchangeable.
