Valentine’s Day Breakup: React Dumps Create React App
Vite is a modern frontend build tool used to develop fast and super efficient web applications. It serves files instantly and ensures that changes are updated immediately after they are implemented. It makes use of Rollup for optimized builds and has support for when you want to build a Javascript library (instead of a full app).

Node.js: A brief history of cjs, bundlers, and esm
npm packages dramatically sped up the productivity of developers by being able to leverage other developers' work. However, it had a major disadvantage: cjs was not compatible with web browsers. To solve this problem, the concept of bundlers was born. browserify was the first bundler which essentially worked by traversing an entry point and "bundling" all the require()-ed code into a single .js file compatible with web browsers. As time went on, other bundlers with additional features and differentiators were introduced. Most notably webpack, parcel, rollup, esbuild and vite (in chronological order).

Custom builder for Angular: My way
Micro-frontend has always aroused my curiosity: I wanted to understand how they work, how to build them, what their pros and cons are. In 2018, inspired by this topic, I tried to build something similar to single-spa in one of the pet projects. At that time, there was no Webpack Module Federation (WMF), and Webpack itself seemed inconvenient. The choice fell on ESBuild and importmap. Browser support for importmap at the time was mostly on paper or with special flags in browsers. For this reason, I used a polyfill. But, surprisingly, everything worked and even in several projects.
