  • yarn vs npm. Which one's better?

Posted By: shen | 1 Replies | Last Reply On: Jul 21, 2021 12:04:20

I have recetly started working on the Node.js as backend technology for a project and I have come across npm and Yarn. But I do not know which one is better than the other and why. I also read a several articles but found them information overload and hence looking for a much simplistic answer to this question.

To begin with, we will try to understand what these two are used for. Yarn and npm are both package managers, which means they are essentially used to automate installing, configuring and managing software on a system.

npm: Node Package Manager
It is a default package manager for JavaScript programming language and is used for JavaScript runtime environment Node.js.

Yarn: Yet Another Resource Negotiator
Yarn is also a package manager like npm and is developed by Facebook to fix performance and security concerns with npm.

Since its introduction, the yarn has become more popular and has become the preferred package manager over npm for the reasons mentioned below.

Security
npm runs code from dependencies automatically and on the fly, raising a few security concerns. On the other hand, yarn can also be run offline to install packages if you have already installed them in the past.

Version Controlling
npm needs an internet connection to install packages and runs code from dependencies automatically and on the fly. This created many issues as it automatically picked up a new version of a dependency that could break your build. Another major issue programmers have faced is that they have deleted several npm Packages that many users are using. Yarn only installs from your yarn. lock or package.json files. Yarn.lock ensures that the same package is installed throughout all devices. This reduces the possibility of bugs from having different versions installed.

Speed
Yarn can install multiple packages at once compared to npm, which installs one at a time. Yarn installs packages in a parallel manner, which means installing the packages side by side, unlike the serial manner followed by npm.  

 

Conclusion

With new improvements, npm managed to overcome most of its limitations with their version 5. Both npm and yarn are great tools in managing your project's dependencies. But it solely depends on your project requirement that should entice you to choose one over the other.
