Actually, npm is two things - a package manager and a package registry. Npm is the default package manager bundled with the Node.js runtime. This will mainly focus on where and how packages are installed.

Instead, we're looking at how these package managers do their base job – manage your packages. We won't be looking at features like workspaces, which all three of these share. Today we'll be looking at three package managers: npm, Yarn, and pnpm.Īll of the package managers we'll be talking about have rough parity. Picking the right package manager for your project can save you time, money, and headache. However, in a world of CICD pipelines, we want builds to be a quick as possible so that we can save at least a little money and time. You'll only really interact with them when you're installing new dependencies or running one of those commands mentioned previously. They can affect installation time (and thus build time), but are largely transient outside of those important activities. Package managers have an interesting place in the project structure. Beyond that, package managers also help manage shared code in monorepos and allow developers to create easy-to-access commands in their projects. Simply put, a package manager is software that handles the installation and management of third party packages. By the end of this, you'll have a better understanding of each one and maybe an easier time picking one for your next project.

Today, we're going to look at the prominent three Node package managers. However, that does mean you need an informed opinion about most of your tooling options, which can be be a daunting task. We get to pick exactly what tools we use and there usually isn't one right way to solve a problem.

One of the things I love about the JavaScript ecosystem is the amount of options we have to solve basically every problem.
