LetвЂ™s first explore some of the identical commands: Npm and Yarn share many commands, but there are also many non-identical commands. In the next section, weвЂ™ll explore more commands. So far, weвЂ™ve seen that npm and Yarn have different commands for installing packages. But this is changed in versions 2 and 3, where the logs arenвЂ™t so intuitive and human-readable. TheyвЂ™re also ordered in a tree form for easy comprehension. If youвЂ™re using Yarn 1, youвЂ™ll see that the yarn output logs are clean, visually distinguishable and brief. Yarn installs packages in parallel, which is one of the reasons itвЂ™s quicker than npm.

To install the packages with Yarn, we run the yarn command. The output logs in the terminal are informative but a bit hard to read. When we run npm install, the dependencies are installed sequentially, one after another. Now, letвЂ™s see how project dependencies are installed.

HereвЂ™s how to install multiple versions of Node using nvm. To do the same with npm, youвЂ™ll need to have nvm (Node Version Manager) installed. With Yarn we can use a different version for each project.

#Yarn add save dev update#

If we want to update to the latest version, we run this: yarn set version latest In this case, berry is the version we want to set. We do that by running the yarn set version command in the projectвЂ™s root directory: yarn set version berry Then, we can use it on a per-project basis by setting the desired version inside our project. First, we need to install Yarn globally: npm install -g yarn In contrast, Yarn needs to be installed explicitly. Installing the package managers themselvesДЄs I noted above, npm comes preinstalled with Node, so thereвЂ™s no need to install npm manually. WeвЂ™ll start our comparison exploration with the installation process for both npm and Yarn.

In the rest of this tutorial, weвЂ™ll explore the main similarities and differences between npm and Yarn. But there are still several differences that help to determine which we choose to use. Nowadays, both package managers are neck and neck in the package management race, offering similar features and capabilities.

2021: Yarn 3 is released with various improvements.

Both packages come with great new features, as weвЂ™ll see later in this tutorial. Now npm checks security vulnerabilities before dependencies are installed.

2018: npm 6 is released with improved security.It offers auto-generation of a package-lock.json file in answer to yarn.lock. It also generate a yarn.lock file that makes sharing and exact replication of repos much easier and predictable. It shows much greater performance than npm. 2010: npm is released with support for Node.LetвЂ™s quickly travel through time to see the big picture: Yarn was quickly positioned as a safe, fast, and reliable JavaScript dependency management tool.Д«ut the npm team learned their lesson and rapidly filled the npm gaps by implementing the missing features. The original goal of Yarn was to deal with npm drawbacks, such as performance and security issues. The Yarn package manager is an alternative to npm, released by Facebook in October 2016. Yarn stands for Yet Another Resource Negotiator. If youвЂ™d like a deep dive into working with npm, please consult our Node Package Manager Guide. This means you can start using it right away. It ships as a default package manager with each fresh Node installation. However, when most people talk about npm, they usually mean the last one - the CLI tool. a command-line interface (CLI) for interacting with npm via the terminal.a registry for accessing an extensive public database of JavaScript packages.a website for managing various aspects of your npm experience.npm was the magic wand that pushed the Web to the next level. Until then, the project dependencies were downloaded and managed manually. It was released back in 2010, beginning a new era in web development.

All the hard and tedious work is done by the package manager, leaving to us only the fun part - the coding itself.

For example, with the help of a package manager we can install, uninstall, update, and upgrade packages, configure project settings, run scripts, and so on. And this is the place where package managers come into play.ДЄ package manager is a tool that automatically handles a projectвЂ™s dependencies in a variety of ways. Nowadays, itвЂ™s common for even a fairly simple project to have hundreds or thousands of scripts, with complex nested dependencies, which are simply impossible to manage without some kind of automated tool. But since then, the Web has changed drastically. Back in the good old days, a simple text editor was enough for developers to create and manage the large part of their projects.
