The web is inherently unreliable. Whether you're calling an external API, performing a complex calculation, or waiting for a user operation to complete, things can go wrong. One of the most insidious issues is when operations simply hang - they neither succeed nor fail, leaving your application in limbo. This is where timeout patterns come to the rescue.

In modern distributed systems, failures are inevitable. Whether it's a network outage, service downtime, or resource exhaustion, your application needs to gracefully handle these scenarios. This article explores various fallback patterns in TypeScript that can help build more resilient systems.

Learn about resilience patterns and how to implement the Circuit Breaker pattern in TypeScript to build robust applications.

In today's web applications, handling user input efficiently is crucial for performance. One common challenge is managing frequent events like window resizing, scroll events, or real-time search input. This is where the debounce function comes in handy – a powerful technique to control how often your code executes.

Learn how to simplify your TypeScript classes with the constructor shorthand syntax. This technique helps you write cleaner and more concise code.

Despite useReducer has been always linked to redux, it's the most awesome hook and way more superior than useState to handle the state.

It's quite impressive the technical skills chatGPT has developed, at least to evaluate the adoption of a technology. Change DDD by any other technology and you'll get the same result.

One of the rule to optmize context api performance is to split make them small. This can be translated in a bigger amount of smaller contexts, and just like that, you will end up with the Context pyramid of hell.

Let’s take a look at how to test a react component that is dependent

Think about everything that involves making requests: loading states, error handling, cache, latency...

Sometimes, you need to render JSX conditionally based on some conditions or state. Read how we can use reducers to avoid ternary operations abuse.

Polling, in computer science, refers to actively sampling the status of an external source of data. For instance, it's a common technique when you upload a file to the server and you want to measure the progression. It's useful also when you want to check if some external library has been loaded and it's ready to use.

Last week I was coding a feature in my current project and I learned something new. Well, better said, something I didn't know or something I was using wrong.

I’ve been reading a lot about _design tokens_ lately, and I think they’re super interesting. Design tokens are tiny pieces of UI information to store design related information such as colors, fonts, spaces, animations, etc...

State management in complex React applications was a hard task before redux came up. Redux is a small library designed to manage the state of data in JavaScript applications.

Documentation is a key part and more often under-rated aspect of any product.

Everyone knows what popup notifications are, but what does `Toast` mean?

Our unit tests should never rely on code that is outside our control and they certainly shouldn't be calling across the network to a server. A good test needs to be repeatable and fast and relying on outside systems and/or data doesn't help us meet those goals.

Vivimos una crisis sanitaria y económica sin precedentes, en todo el mundo. Más de un tercio de la población mundial está en confinamiento, trabajando desde casa, los que podemos, sin la libertad de salir a dar un paseo, algo tan simple y que todos damos por hecho.

First of all, is css reset still needed in 2019? I actually think it never has been necessary. But a CSS reset will help you to make your project maintain the look and feel between every browser and might save you a lot of time of browser-testing and debugging.

Vivimos tiempos complejos, donde el nivel de exigencia es altísimo. Lo que llamamos social media, nos bombardea a diario, a todas horas, con contenido acerca de lo que podríamos ser y como conseguirlo.
