When dealing with a large and complex web application, you might often run into situations where an operation is slower than it should. Let's see how we can run a performance trace to find out what's slowing things down.

Recently I had work on getting hot reload to work in a module federated CRA. I faced this issue, and couldn't easily find good solutions, and had to dive a bit deep into webpack docs. This post provides a quick solution for this issue.

Recently, I had to integrate a tailwind based design system into a CRA app as a git submodule, and make it work with Storybook, Chromatic, GH Actions and Netlify. This post is a documentation of all the issues I faced.

I had to develop a server in Node which would act as a proxy and hit multiple different servers on behalf of the client, aggregate their responses, and send it back to the client. This post discusses a few approaches to achieve that.

We write JS code, and then send it to the client's browser, where it is executed. To write better code, it's good to have an understanding of how the code we write is going to be executed. This post explores how Chrome's JS engine (V8) runs JS code efficiently.

Understanding the tooling is crucial to understand what exactly is happening to the code we write, which helps us write better, bug-free code. This post is a collection of notes I made to understand more about the tools used in the JavaScript ecosystem.

Recently, I ran into a problem while using setInterval in React. The function you pass to setInterval is defined once and it closes over the old value of your component state. This becomes a problem when you want to use the state to determine whether to clear the setInterval. Read on to find out the solution that worked for me.

A discussion about the asynchronous parts of JavaScript. Is JavaScript really asynchronous? How can it be asynchronous if the browser engine has only one thread? Well, read on to find out!

Concurrency, Parallelism and Asynchrony are basic terms that are often confused with each other. This is a short post explaining the meaning behind the terms and how they differ from each other.
