Difference between npm and yarn

Package managers like npm and yarn assist in managing a project's dependencies. A dependency is a component of code that a project needs to function properly. They are necessary because maintaining the project's dependencies is a challenging chore that inevitably grows tiresome and out of control as the project expands. We refer to including, excluding, and updating dependencies as managing them.

What is npm?

The biggest software registry in the world is npm. Every continent's open source developers use npm to exchange and borrow packages, while many businesses use npm to oversee private development. There are three distinct parts to npm:

  1. The website
  2. The command line interface (
  3. CLI)
  4. The Registry

In order to publish open-source Node.js projects, npm is a command-line tool that provides package installation, version control, and dependency management. Its main purpose is to serve as a repository for open-source Node.js projects online. There are many Node.js modules and programs available on npm, and a significant number more are being added daily. These programmes can be researched at https://www.npmjs.com. Once a package is downloaded to your computer, it can be installed with a single command-line command.

Uses of npm

  1. Code packages can be modified for your projects or used just as-is.
  2. Get ready-to-use standalone utilities by downloading them.
  3. Utilize npx to run packages without downloading.
  4. With any npm user, wherever, you may share code.
  5. Establish groups to manage developers, code, and package maintenance.
  6. Control the dependencies and various code versions.
  7. Find various solutions to the same challenge.
  8. Find other developers who are tackling issues and projects that are similar to yours.

What is yarn?

The npm client and other existing package managers' workflows are replaced by yarn, a new package manager that is still compatible with the npm registry. It operates more quickly, more securely, and more consistently while offering the same feature set as current workflows. Any package manager's main job is to install a package—a piece of code with a specific use—into the local environment of an engineer from a global registry. Depending on other packages, each one may or may not be dependent. Within its dependency tree, a typical project may contain tens, hundreds, or even thousands of packages.

Differences between npm and yarn in Tabular form

Parameternpmyarn
Installation procedureNode comes pre-installed with npm.Npm must be installed in order to install yarn.
Output logMassive output logs of npm commands are produced by the tool. In essence, it is a stack trace dump of what npm is doing.The yarn output logs are neat, easily visible, and condensed. For ease of understanding, they are also arranged in a tree format.
The lock fileA file named "package-lock.json" is created by NPM. Due to a compromise between determinism and simplicity, the package-lock.json file is a little bit more complicated. The package-lock will produce the same node modules folder for various npm versions due to this complication. The package-lock file will have a precise version number for each dependency.The yarn creates a file called "yarn.lock." Yarn lock files make merging easier. Due to the lock file's design, the merges are also predictable.
Installing global dependenciesThe command syntax for npm is: npm install -g package name@version number to install a global package.The command template for yarn is yarn global add package name@version number to install a global package.
Fetching packagesEvery time you use the 'npm install' command, npm retrieves dependencies from the npm registry.During a "yarn add" operation, yarn stores dependencies locally and retrieves them from the disc (if the dependency is present locally and has the correct version).
License CheckerBecause of installed dependencies, npm lacks a licence checker that can provide a convenient summary of all the licences that a project is bound by.Yarn provides a nice licencing verification tool. Run yarn licences list to see them.
The ‘why’ commandYet, npm lacks an integrated "why" functionality.Yarn includes a command called "why" that explains why a dependency is included in the project. It could be a dependency, a native module, or a project dependency, for instance.
