NPM stands for Node Package Manager. It is a package manager for the JavaScript programming language. It is used to install, share, and manage code packages that are used in JavaScript projects. It helps developers to easily find, share, and reuse code with other developers from around the world. It also helps maintain the versioning of libraries, making sure that everyone is using the same version of the code.

Yarn: From Design to Implementation
In this talk, we'll go over the various iterations the Yarn team went through designing one of the most critical software in the JavaScript ecosystem. We'll discuss some of the main choices, trade-offs, errors, and successes we faced, and think about evolutions to come and future challenges that await us. By the end of this talk you'll have a better understanding of the work large-scale open-source teams do behind the team, and hopefully a better understanding of what makes open-source so special.

Package-based Monorepos - Speed Up in Under 7 Minutes
They gave me just 7 minutes! So this is a no-slides, just code talk! I'm gonna show you a Yarn/NPM/PNPM workspaces-based monorepo implementation and how we can speed it up. In particular, I'm using Nx on top to get better parallelization, the ability to define task pipelines, caching, and more. Curious? Join me!
