What I learned from making my first OSS NPM package/Component Library
My tech stack was React + Typescript, Storybook for docs, vite.js for build instead of webpack, microbundle for bundling (basically a no-config rollup wrapper), and Google's release please bot for handling release/deployment.

Microbundle is not enough
Setting up a modern Typescript or Javascript development stack is a daunting task, there are a lot of moving parts, and sometimes the whole process seems like magic, so I switched to Microbundle. While microbundle handles the compilation, there are a lot of other moving parts that need to be set up to start developing with Nodejs/Typescript (CI, tests, linting, etc). So I've created an opinionated template repository with Typescript, Microbundle, Jest, eslint, husky, prettier, github actions, pnpm, and a bunch of other scripts. It enables me to start developing a library immediately by using the repository as a starter template. Let me know what you think and if some processes could be improved, or some valuable tools that could be added. Pull requests and suggestions are welcomed.

JavaScript is so redundant
Why are there so many JavaScript build tools? Gulp, Grunt, Webpack, Laravel Mix, Rollup.js, and now Vite. And these are just the ones that I've worked with. Haven't we solved this problem? And why build a new tool? Why not improve existing tools?
