Apache Maven vs npm: What are the differences?

Introduction

Apache Maven and npm are both popular build tools used in software development. While they serve similar purposes, there are several key differences between the two. In this article, we will explore the main differences between Apache Maven and npm.

  1. Dependency Management: Apache Maven is known for its robust dependency management system. It uses a centralized approach where dependencies are defined in a project's pom.xml file, ensuring consistent and reliable builds. On the other hand, npm follows a decentralized approach, where dependencies are managed in a package.json file, allowing for greater flexibility but potentially leading to dependency conflicts.

  2. Build Lifecycle: Maven has a well-defined build lifecycle with various phases such as compile, test, package, and install. This predefined lifecycle ensures that each phase runs in a specific order, enabling developers to easily execute tasks and create project artifacts. In contrast, npm does not have a predefined build lifecycle, and developers can define and execute custom scripts as per their requirements.

  3. Plugins and Extensibility: Maven has a rich ecosystem of plugins that provide additional functionality and integration with other tools. These plugins can be easily configured and executed within Maven's build lifecycle. In comparison, npm provides a minimal set of built-in functionality and relies heavily on external packages for extending its capabilities.

  4. Programming Language Support: Maven is primarily designed for Java projects and has in-built support for Java-specific tasks such as compiling, testing, and packaging Java code. npm, on the other hand, is commonly used for JavaScript projects, but it can also be used for managing dependencies and running scripts for other programming languages like TypeScript, Python, and more.

  5. Scalability and Performance: Maven is known for its scalability and ability to handle large projects with multiple modules and complex dependencies. It excels in managing transitive dependencies and reducing duplication. npm, on the other hand, is optimized for smaller projects and may experience performance issues when dealing with larger codebases.

  6. Community and Ecosystem: Maven has been around for a longer time and has a mature and extensive community. It has a wide range of plugins, documentation, and community support available. npm, being a part of the Node.js ecosystem, also has a vast community with a vibrant package ecosystem, providing access to a plethora of open-source modules.

In summary, Apache Maven is a centralized build tool with a strong focus on dependency management and a predefined build lifecycle, while npm follows a decentralized approach with flexibility in managing dependencies and build scripts. Maven is primarily used for Java projects, while npm is popular for JavaScript projects. Maven has a mature community and extensive plugin ecosystem, while npm benefits from the active Node.js and JavaScript communities.

From a StackShare Community member: “I’m a freelance web developer (I mostly use Node.js) and for future projects I’m debating between npm or Yarn as my default package manager. I’m a minimalist so I hate installing software if I don’t need to- in this case that would be Yarn. For those who made the switch from npm to Yarn, what benefits have you noticed? For those who stuck with npm, are you happy you with it?"

We use Yarn because it allows us to more simply manage our node_modules. It also simplifies commands and increases speed when installing modules. Our teams module download time was cut in half after switching from NPM to Yarn. We now require all employees to use Yarn (to prevent errors with package-lock.json and yarn.lock).

I use npm since new version is pretty fast as well (Yarn may be still faster a bit but the difference isn't huge). No need for other dependency and mainly Yarn sometimes do not work. Sometimes when I want to install project dependencies I got error using Yarn but with npm everything is installed correctly.

p.s.

I am not sure about the performance of the latest version of npm, whether it is different from my understanding of it below. Because I use npm very rarely when I had the following knowledge.

I use Yarn because, first, yarn is the first tool to lock the version. Second, although npm also supports the lock version, when you use npm to lock the version, and then use package-lock.json on other systems, package-lock.json Will be modified. You understand what I mean, when you deploy projects based on Git...

I use npm because I also mainly use React and TypeScript. Since several typings (from DefinitelyTyped) depend on the React typings, Yarn tends to mess up which leads to duplicate libraries present (different versions of the same type definition), which hinders the Typescript compiler. Npm always resolves to a single version per transitive dependency. At least that's my experience with both.

As far as I know Yarn is a super module of NPM. But it still needs npm to run.

Yarn was developed by Facebook's guys to fix some npm issues and performance.

If you use the last version of npm most of this problem does not exist anymore.

You can choose the option which makes you more confortable. I like using yarn because I'm used to it.

In the end the packages will be the same. Just try both and choose the one you feel more confortable. :)

I am a minimalist too. I once had issues with installing Nuxt.js using NPM so I had to install Yarn but I also found that the Dev experience was much better

I use Yarn because it outputs nice progress messages with cute emoji and installs packages quickly if the package is cached. Also, Yarn creates yarn.lock file which makes the developer use the consistent environment.

You should use whichever had the best DX (developer experience) for your team. If you are doing a massive front-end project, consider yarn if not only because it makes it a snap to go from zero to ready. What some people say about npm being more stable or easier for smaller projects is highly true as well. (not to mention, you sometimes have to install yarn) But, note that official NodeJS Docker images ship with both npm and yarn. If you want to use yarn, put package-lock=false and optionally save-exact=true in your project's .npmrc file. Compare whether you prefer the ergonomics of yarn global add over npm install -g or see fewer meaningless warnings for the specific set of dependencies you leverage.

We tend to stick to npm, yarn is only a fancy alternative, not 10x better. Using a self -hosted private repository (via sinopia/npm-mirror) make package locking (mostly) pointless.

As we have to build the application for many different TV platforms we want to split the application logic from the device/platform specific code. Previously we had different repositories and it was very hard to keep the development process when changes were done in multiple repositories, as we had to synchronize code reviews as well as merging and then updating the dependencies of projects. This issues would be even more critical when building the project from scratch what we did at Joyn. Therefor to keep all code in one place, at the same time keeping in separated in different modules we decided to give a try to monorepo. First we tried out lerna which was fine at the beginning, but later along the way we had issues with adding new dependencies which came out of the blue and were not easy to fix. Next round of evolution was yarn workspaces, we are still using it and are pretty happy with dev experience it provides. And one more advantage we got when switched to yarn workspaces that we also switched from npm to yarn what improved the state of the lock file a lot, because with npm package-lock file was updated every time you run npm install, frequent updates of package-lock file were causing very often merge conflicts. So right now we not just having faster dependencies installation time but also no conflicts coming from lock file.

This was no real choice - we switched the moment Yarn was available, and never looked back. Yarn is the only reasonable frontend package manager that's actually being developed. They even aim to heal the node_modules madness with v2! Npm is just copying its ideas on top of introducing massive bugs with every change.

What is Apache Maven?

Maven allows a project to build using its project object model (POM) and a set of plugins that are shared by all projects using Maven, providing a uniform build system. Once you familiarize yourself with how one Maven project builds you automatically know how all Maven projects build saving you immense amounts of time when trying to navigate many projects.

What is npm?

npm is the command-line interface to the npm ecosystem. It is battle-tested, surprisingly flexible, and used by hundreds of thousands of JavaScript developers every day.
