JSPM vs npm: What are the differences?

Package Manager: JSPM (JavaScript Package Manager) is specifically designed for managing JavaScript packages and modules for front-end development, while npm (Node Package Manager) is primarily used for managing Node.js packages and modules for both front-end and back-end development.
Transpilation: JSPM supports transpilation of ES6 code to ES5 code whereas npm needs additional tools like Browserify or Babel to achieve the same functionality.
Dependency Resolution: JSPM uses SystemJS to provide dynamic dependency loading and resolution at runtime, whereas npm requires static dependency management and resolution during the initial installation phase.
Multiple Environments: JSPM is suitable for building and managing packages for web and Node.js environments, while npm is primarily geared towards Node.js development.
Configuration: JSPM uses a configuration file (jspm.config.js) for managing settings and specifying dependencies, while npm uses package.json for similar purposes.
Tree Shaking: JSPM has built-in support for tree shaking, which helps in eliminating unused code during the build process for better performance, while npm does not have native support for tree shaking.

In Summary, JSPM is focused on managing front-end JavaScript packages with features like transpilation, dynamic dependency resolution, and tree shaking, while npm is a more versatile package manager suitable for both front-end and back-end JavaScript development.

Advice on npm, JSPM

Node.js

Yarn

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?"

React

TypeScript

Yarn

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.

Decided

Why migrated?

I could define the next points why we have to migrate:

Decrease build time of our application. (It was the main cause).
Also jspm install takes much more time than npm install.
Many config files for SystemJS and JSPM. For Webpack you can use just one main config file, and you can use some separate config files for specific builds using inheritance and merge them.

Detailed Comparison

npm	JSPM
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.	It is a package manager for the SystemJS universal module loader, built on top of the dynamic ES6 module loader. You can load npm packages in modern browsers with the native browser ES module loader.

What are some alternatives to npm, JSPM?

Meteor

A Meteor application is a mix of JavaScript that runs inside a client web browser, JavaScript that runs on the Meteor server inside a Node.js container, and all the supporting HTML fragments, CSS rules, and static assets.

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.

Elm

Writing HTML apps is super easy with elm-lang/html. Not only does it render extremely fast, it also quietly guides you towards well-architected code.

RequireJS

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.

Browserify

Browserify lets you require('modules') in the browser by bundling up all of your dependencies.

Julia

Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library.

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.

Racket

It is a general-purpose, multi-paradigm programming language based on the Scheme dialect of Lisp. It is designed to be a platform for programming language design and implementation. It is also used for scripting, computer science education, and research.

Component

Component's philosophy is the UNIX philosophy of the web - to create a platform for small, reusable components that consist of JS, CSS, HTML, images, fonts, etc. With its well-defined specs, using Component means not worrying about most frontend problems such as package management, publishing components to a registry, or creating a custom build process for every single app.

PureScript

A small strongly typed programming language with expressive types that compiles to JavaScript, written in and inspired by Haskell.
