npm vs RequireJS: What are the differences?

npm: The package manager for JavaScript. 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; RequireJS: JavaScript file and module loader. RequireJS loads plain JavaScript files as well as more defined modules. It is optimized for in-browser use, including in a Web Worker, but it can be used in other JavaScript environments, like Rhino and Node. It implements the Asynchronous Module API. Using a modular script loader like RequireJS will improve the speed and quality of your code.

npm and RequireJS can be primarily classified as "Front End Package Manager" tools.

"Best package management system for javascript", "Open-source" and "Great community" are the key factors why developers consider npm; whereas "Open source", "Modular script loader " and "Asynchronous " are the primary reasons why RequireJS is favored.

npm and RequireJS are both open source tools. npm with 17.2K GitHub stars and 3.17K forks on GitHub appears to be more popular than RequireJS with 12.2K GitHub stars and 2.3K GitHub forks.

According to the StackShare community, npm has a broader approval, being mentioned in 2642 company stacks & 2666 developers stacks; compared to RequireJS, which is listed in 916 company stacks and 185 developer stacks.

    What are some alternatives to npm and RequireJS?
    Yarn
    Yarn caches every package it downloads so it never needs to again. It also parallelizes operations to maximize resource utilization so install times are faster than ever.
    gulp
    Build system automating tasks: minification and copying of all JavaScript files, static images. More capable of watching files to automatically rerun the task when a file changes.
    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.
    Bower
    Bower is a package manager for the web. It offers a generic, unopinionated solution to the problem of front-end package management, while exposing the package dependency model via an API that can be consumed by a more opinionated build stack. There are no system wide dependencies, no dependencies are shared between different apps, and the dependency tree is flat.
    NuGet
    A free and open-source package manager designed for the Microsoft development platform. It is also distributed as a Visual Studio extension.

    I have mixed feelings on the Yarn/npm/Node.js ecosystem. We use it for Zulip, because you basically have to in order to have a modern JavaScript toolchain. And I like that Yarn lets us pin dependency versions out of the box for predictability in our production releases; we have to do significant work for the Python version of this feature.

    But one also deals with broken third-party dependencies uploaded to npm way too often (even ignoring the malicious packages issues that have gotten a lot of press of late). And one mostly has to use nvm in order to pin a specific version of node itself in a maintainable way, and nvm is a mess.

    We use Yarn because at the time we decided to adopt it, npm had some missing features and issues. We like the speed and determinism provided by Yarn. We could probably use npm at this point, but we have no real reason to switch from Yarn. If you have a convincing argument to switch from npm to Yarn please leave a comment on this decision!

    So when starting a new project you generally have your go to tools to get your site up and running locally, and some scripts to build out a production version of your site. Create React App is great for that, however for my projects I feel as though there is to much bloat in Create React App and if I use it, then I'm tied to React, which I love but if I want to switch it up to Vue or something I want that flexibility.

    So to start everything up and running I clone my personal Webpack boilerplate - This is still in Webpack 3, and does need some updating but gets the job done for now. So given the name of the repo you may have guessed that yes I am using Webpack as my bundler I use Webpack because it is so powerful, and even though it has a steep learning curve once you get it, its amazing.

    The next thing I do is make sure my machine has Node.js configured and the right version installed then run Yarn. I decided to use Yarn because when I was building out this project npm had some shortcomings such as no .lock file. I could probably move from Yarn to npm but I don't really see any point really.

    I use Babel to transpile all of my #ES6 to #ES5 so the browser can read it, I love Babel and to be honest haven't looked up any other transpilers because Babel is amazing.

    Finally when developing I have Prettier setup to make sure all my code is clean and uniform across all my JS files, and ESLint to make sure I catch any errors or code that could be optimized.

    I'm really happy with this stack for my local env setup, and I'll probably stick with it for a while.

    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.

    #Frontend

    I think our #Frontend stack is pretty standard – but we have taken some deviations from a typical modern stack:

    • Flow (JS) instead of TypeScript. Flow was an easy choice 2+ years ago, as both flow and React were (and still are) maintained by Facebook. Today, it seems that the JavaScript community has settled on TypeScript as the winner. For new projects, I'd choose TS, but I don't see the point in migrating an existing project from flowtype to TS, when the end result will be roughly the same. Sure, memory usage is a bit high, and every now and then I have to kill some zombie processes, but our text editors (Sublime Text), CI scripts, and Babel are already set up to take advantage of the type safety that flow offers. When/if the React team writes React itself in TS, then I'll take a closer look – until then, flow works for us.

    • Yarn instead of npm. When yarn debuted, we never looked back. Now npm has pretty much caught up with speed and lockfiles, but yarn gives me confidence that my dependency installs are deterministic. Really interested in the plug-n-play (PnP) feature that removes the need for a node_modules folder, but haven't implemented this yet.

    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?"

    Utilize npm private module to package shared library for different React / React Native clients. Shareable code goes here. Basically deliver Redux Store with Firebase integration and business logic in a library. Each React app utilizes this while delivering a device/target specific UI.

    If you're using Node or Gulp, you can't help but use NPM in some form or another. Fortunately that's never a bad thing with the massive package repository and glowing ecosystem making it a breeze to work with.

    We manages all of our packages, including Angular JS through npm. It is a very quick way of downloading / installing packages into your project.

    Module is published as bpost on the npm registry. Tasks for the module are also defined as npm run tasks with commit hooks for git

    Used Require.js to make the application modular. It provides better dependency management with asynchronous loading of scripts.

    No real definitive reason, I find it to be the most natural way to import libraries and code in nodejs (prior to ES6 / import).

    The RequireJS package manager is used by various web applications and services to manage dependencies on 3rd party libraries.

    It's the front-end version of Composer, so is pretty essential to pull in packages that can be tracked and kept up to date.

    Very nice way to structure a project, as long as you know it will not be a hybrid app.

    RequireJS is the main component until Magento 2.2.x for frontend development.
