Editor’s note: This article was updated on 10/25/22 by our editorial team. It has been modified to include recent sources and to align with our current editorial standards. React was developed to create interactive UIs that are declarative, modular, and cross-platform. Today, it is one of the more popular—if not the most popular—JavaScript frameworks for writing performant front-end applications.

Motion has a profound impact on the user experience of digital products, but if interface elements don’t exhibit basic motion design principles, usability is undermined. In the context of user interfaces, motion is more than a visual garnish. It is a compelling force that bolsters product engagement and extends the reach of design communication. Our world is one of movement. Even in still moments,

Hooks were introduced in React 16.8 in late 2018. They are functions that hook into a functional component and allow us to use state and component features like componentDidUpdate, componentDidMount, and more. This was not possible before. Also, hooks allow us to reuse component and state logic across different components. This was tricky to do before. Therefore, hooks have been a game-changer. In

Leveraging the stale-while-revalidate HTTP Cache-Control extension is a popular technique. It involves using cached (stale) assets if they are found in the cache, and then revalidating the cache and updating it with a newer version of the asset if needed. Hence the name stale-while-revalidate. How stale-while-revalidate Works When a request is sent for the first time, it’s cached by the browser. T

When starting a new React project, you have many templates to choose from: Create React App, react-boilerplate, and React Starter Kit, to name a few. These templates, adopted by thousands of developers, are able to support application development at a very large scale.

By 1999, eBay had become America’s leading auction site and was expanding into new global markets. With its eyes on Japan, eBay replicated its US model, bought a local domain, and translated its site into Japanese. Three years after launching, dire performance forced eBay to pull out. Aside from strong local competition, eBay’s failure was due to a limited understanding of the cultural differences

In recent years, with the advent of concepts such as cloud computing and big data, distributed systems have gained popularity and relevance. One such type of system, distributed caches that power many high-traffic dynamic websites and web applications, typically consist of a particular case of distributed hashing. These take advantage of an algorithm known as consistent hashing. What is consistent

Ruby on Rails ships with everything you need to prototype your application quickly, but when your codebase starts growing, you’ll run into scenarios where the conventional Fat Model, Skinny Controller mantra breaks.

Let’s take the GET /users/:id/projects endpoint: Say I want to show only the projects’ titles on the home page, but projects+tasks on the dashboard, without making multiple REST calls. I would call: GET /users/:id/projects for the home page. GET /users/:id/projects?include=tasks (

Why Should We Care about iOS ARKit Now? Every experienced developer is probably aware of the fact that AR is an old concept. We can pin down the first serious development of AR to the time developers got access to individual frames from webcams. Apps at that time usually were used to transform your face. However, humanity didn’t take long to realize that transforming faces into bunnies wasn’t one

Understanding the Input/Output (I/O) model of your application can mean the difference between an application that deals with the load it is subjected to, and one that crumples in the face of real-world use cases. Perhaps while your application is small and does not serve high loads, it may matter far less. But as your application’s traffic load increases, working with the wrong I/O model can get
