Yarn vs. NPM: Which one should you use?

As a developer, it takes time to decide which dependency manager to use. Several of them, such as Yarn and NPM, but which is better? You’ve got a Yarn vs NPM battle in your mind, but what if they’re not as similar as they seem? Is one better than the other? Let’s try and answer these questions!


A yarn package manager is a tool that enables you to organize your dependency management. It is capable of installing, updating, and removing dependencies. This concept is also known as “dependency management.”

It is a package manager that runs in Node.js and has a similar interface to npm. It’s used for managing dependencies and modules, simplifying working with JavaScript libraries.


NPM is a package manager for NodeJS projects. It allows you to manage your packages and publish them on npmjs.com. NPM is also commonly used with front-end development, where it can help with tasks such as installing plugins or setting up your project’s build process.

It is a package manager that runs in Node.js and has a similar interface to Yarn. It’s used for managing dependencies and modules, simplifying working with JavaScript libraries.

Ways you can use Yarn

  1. Yarn is a handy package manager that efficiently manages your dependencies. It supports many languages, like JavaScript and Python, and can automatically install packages via npm or bower. 
  1. You can also use it to build your packages with the help of plugins such as Yarn Start and Yarn Test.
  1. Another benefit of using Yarn is that it makes building projects easier by allowing users to specify different versions of dependencies at different times during development. This means that developers can change dependency versions during development, which can cause inconsistent builds and slow down the process.
  1. When building your packages, you want to ensure they are compatible with whatever build tool is used. The best way to do this is by using yarn check. This will ensure that all dependencies are compatible, so there aren’t any issues when compiling or running tests for your project.
  1. Using yarn check will also ensure that your project is compatible with the local system’s package manager (if there is one). This can save you a great deal of time if you work in an environment where multiple people work on the same project.

Ways you can use NPM

1. NPM can be used to run your local server (e.g. for development purposes)

2. NPM is the package manager for Node.js, which means that you can use it to install other packages

3. NPM is a module manager that allows you to install, update and remove packages from your project’s dependencies

4. You can use npm as a tool for managing your workflow when developing an application or library

5. You can use npm to manage your project dependencies

6. NPM allows you to create a package. JSON file to define the components of your application

7. Developers also use NPM as a way to share and publish libraries and packages

Difference between Yarn vs. NPM

Here are some critical differences between Yarn vs NPM:

1.SpeedYarn is generally faster and more reliable.NPM is not faster and more reliable than Yarn.
2.Dependency managementYarn uses a flat dependency graph, i.e., only allows one package version to be installed at a time.NPM uses a nested dependency graphi.e NPM allows multiple versions of a package to be installed and used in different application parts.
3.CompatibilityYarn is compatible with the npm registry.All npm packages are not compatible with Yarn.
4.SecurityYarn includes security features such as automatic checking for known vulnerabilities.Security features such as automatic checking for known vulnerabilities are unavailable in NPM
5.WorkspacesYarn has built-in support for workspaces, which allows multiple packages to be managed in a single repository.NPM does not have this feature but can be implemented using third-party tools.

Overall, both Yarn and NPM are popular and widely used package managers, and both have their strengths and weaknesses. It ultimately depends on your specific requirements and preferences regarding which one to use. Some developers prefer to use Yarn for new projects and NPM for existing projects to take advantage of the strengths of each.

Yarn vs. NPM: Which one should you use?

Yarn and npm are package managers, but they have some critical differences.

Yarn is the more flexible of the two systems. It supports many package formats, including Bower, Component, and NPM. Yarn can also manage private dependencies, so it packages you don’t want to publish on your public server privately. 

Yarn uses a rolling-release model, which downloads newer versions of your dependencies when updated. This means you don’t have to worry about downloading old versions of dependencies and having them break your app. However, this also means that new versions of dependencies may only work with old versions of the dependency packages if they are updated.

NPM supports a few package formats (currently just npm and npm-shrinkwrap) and does not support private dependencies or rolling releases. NPM has built-in caching functionality to avoid downloading unnecessary files for future requests. This can be very useful as it prevents unnecessary requests, which can be a problem if your app has a lot of dependencies. 

Dependency tree resolution is a feature of NPM that automatically finds all the dependencies an npm package needs to run. This is great for development because you can test only one package at a time instead of installing everything in the node_modules directory of your project.


When choosing Yarn vs NPM, remember that finding a solution that works with your workflow is essential. Both tools mentioned above do precisely what they say they do and can significantly help streamline your process. NPM has most of the same features as Yarn and will only keep adding more as time goes on. Use whichever you feel most comfortable with—both are fantastic solutions for developers!
