Nevertheless, it’s bundled with the Node.js runtime. Mistakenly, many people believe npm is an acronym for “Node package manager” but this is not the case. Npm is the forefather of package managers. Let’s dive into a brief history of how these needs were identified after npm rose to prominence, how Yarn Classic solved some of them, how pnpm has expanded on these concepts, and how Yarn Berry, as Yarn Classic’s successor, tried to break the mold set by these traditional concepts and processes.

Different degrees of configurability and flexibility.

Relatedly, different needs for extensibility through plugins and community tools.

Differing needs for new tools and commands, each of which have DX implications.

Different support for multi-package projects (a.k.a., workspaces), which impacts the maintainability and speed of large monorepos.

Different approaches to storing packages on disk, which has implications on disk-space efficiency.

Different lock file formats, each of which have performance implications.

Different support for hoisting, which has security implications.

Different dependency resolution algorithms with different node_modules folder structures (nested vs.

If npm has been around for over 10 years, why are there any alternatives at all? Here are some key reasons why that have emerged: It established the core principles of how package managers work today. The very first package manager ever released was npm, back in January 2010. A brief history of JavaScript package managers This is the project I also used to create the performance table in the below section of this post.Īlthough the type of application is not important for the topic of this article, I have chosen a mid-size and realistic project to be able to illuminate different aspects as an example from the recent past, Yarn Berry’s PnP mechanism caused some heated discussions about compatibility issues that this project is suited to help examine. There exists a corresponding Git branch for every package manager variant. I’ve created a companion React app to demonstrate some of the different package managers’ unique concepts.

A brief history of JavaScript package managersįeel free to skip around and read what’s most relevant to you.

In this article, we’ll cover the following things, comparing implementation options where applicable:

Yarn Berry goes even further by ditching node_modules completely with its Plug’n’Play (PnP) mode. Thus, pnpm has introduced some new concepts to store dependencies more efficiently in a nested node_modules folder. But this dependency resolution strategy is not free of criticism. Traditionally, npm and Yarn have installed dependencies in a flat node_modules folder.

Batch install or update all dependenciesĭespite this parity, though, package managers differ under the hood.You can do the following with any of these package managers: Of course, how you choose to use each package manager will differ, but they all share a set of main concepts. Virtually, we’ve achieved feature-parity among all package managers, so most likely you’ll decide which package manager to use based on non-functional requirements, like installation speed, storage consumption, or how it meshes with your existing workflow. Yarn - We will see shortly that Yarn can refer to either Yarn Classic (Three major players exist in the field of package managers today: JavaScript package managers compared: npm, Yarn, or pnpm?Įditor’s note : This post was completely rewritten 16 February 2022 to reassess the package manager landscape, reference and compare new tools and workspaces, discuss Corepack functionality and performance impacts, provide a bird’s-eye view of package manager usage among popular open source projects, and more thoroughly explain the evolution of package managers since 2010.

My fire for web development still blazes. I have followed the GatsbyJS theme tutorial pretty much verbatim, except I made multiple "site" packages.Sebastian Weber Follow Frontend developer from Germany. Here is what my root package.json contains. Because themes are almost like "mini" GatsbyJS sites.

Your dependencies can be linked together, which means that your workspaces can depend on one another while always using the most up-to-date code available. Because my biggest disk eater is node_modules folders littered across my computer. Workspaces allow you to develop multiple packages in one way that only requires a single yarn install and shared dependencies.
