  • npm:

    npm supports TypeScript through third-party tools like TypeScript Compiler (tsc) and Babel. However, it does not provide native TypeScript support, and developers must set up their own configurations.

  • bun:

    bun has experimental TypeScript support, but it is not as mature as Deno's. It can handle TypeScript files, but developers may encounter limitations and bugs.

  • deno:

    deno provides first-class TypeScript support out of the box, with no configuration required. It is designed to work seamlessly with TypeScript, making it a great choice for TypeScript projects.

Module System

  • npm:

    npm primarily uses the CommonJS module system, but it also supports ES modules. The dual support allows for compatibility with a vast array of existing JavaScript code.

  • bun:

    bun uses the standard ES module system, which promotes modern JavaScript practices. It also supports CommonJS modules, making it compatible with a wide range of existing code.

  • deno:

    deno uses the ES module system exclusively, with a URL-based import system that eliminates the need for package.json files. This encourages a more modern and modular approach to coding.

Ecosystem and Community

  • npm:

    npm has the largest and most established ecosystem of packages and tools in the JavaScript world. Its long history and widespread use make it the go-to choice for most developers.

  • bun:

    bun is a newer project with a rapidly growing community and ecosystem. It is gaining popularity for its performance and modern features, but it is still in the early stages compared to more established tools.

  • deno:

    deno has a vibrant and active community, with increasing adoption and a growing ecosystem of libraries and tools. Its focus on modern features and security has attracted many developers.

Ease of Use: Code Examples

  • npm:

    npm is widely understood and used, but its complexity can be daunting for beginners. The vast amount of documentation and community resources helps mitigate this. Example: npm install package-name

  • bun:

    bun is designed to be user-friendly, with a simple CLI and intuitive APIs. Its documentation is clear and helpful, making it easy for developers to get started. Example: bun run script.js

  • deno:

    deno is also user-friendly, especially for TypeScript developers. Its security model and clear error messages help users understand and manage permissions. Example: deno run --allow-read script.ts

How to Choose: npm vs bun vs deno
  • npm:

    Choose npm if you are working on a project that requires a mature ecosystem with a vast library of packages. It is the best choice for compatibility and access to a wide range of tools and libraries.

  • bun:

    Choose bun if you prioritize performance, especially for bundling and transpiling JavaScript code. It is ideal for modern projects that can leverage its speed and built-in features.

  • deno:

    Choose deno if you need a secure runtime with first-class TypeScript support and a focus on modern JavaScript features. It is suitable for projects that require enhanced security and a more streamlined module system.

Similar Npm Packages to npm

npm (Node Package Manager) is the default package manager for JavaScript and is widely used for managing packages in Node.js applications. It provides a robust ecosystem for developers to share and reuse code, manage dependencies, and automate various tasks in their projects. While npm is the most popular choice for package management, there are several alternatives that cater to different needs and preferences. Here are a few notable alternatives:

  • bower was a popular package manager for front-end dependencies, allowing developers to manage libraries and frameworks like jQuery, Bootstrap, and others. Although Bower has fallen out of favor in recent years due to the rise of npm and other modern tools, it was once a go-to solution for managing client-side packages. Developers who still work on legacy projects may encounter Bower, but for new projects, it is generally recommended to use npm or other modern alternatives.
  • jspm is a package manager that focuses on module loading and dependency management for JavaScript applications. It leverages the SystemJS module loader and allows developers to import packages directly from the npm registry or other sources. With its emphasis on ES modules and the ability to work seamlessly with modern JavaScript, jspm is a great choice for projects that require a modular approach to package management.
  • npm-check-updates is a command-line tool that helps developers manage and update their npm dependencies. It scans the project's package.json file and checks for newer versions of the installed packages, allowing developers to easily upgrade their dependencies to the latest versions. While it doesn't replace npm, it complements it by providing a streamlined way to keep dependencies up to date.
  • pnpm is an alternative package manager that aims to improve the performance and efficiency of dependency management. Unlike npm, pnpm uses a unique approach to store packages in a global store and creates hard links to them in the project's node_modules directory. This results in faster installations and reduced disk space usage. pnpm is an excellent choice for developers looking for a more efficient package management solution.
  • yarn is another popular alternative to npm, developed by Facebook. It offers a more deterministic approach to package management, ensuring that the same dependencies are installed across different environments. Yarn also includes features like workspaces for managing monorepos, offline caching, and a more user-friendly command-line interface. Many developers prefer Yarn for its speed and reliability, especially in larger projects.

  • deno is a secure runtime for JavaScript and TypeScript that is built on V8, the same engine that powers Chrome. Deno emphasizes security, simplicity, and modern features, such as TypeScript support out of the box. Unlike traditional Node.js environments, Deno does not use a centralized package manager like npm; instead, it allows developers to import modules directly from URLs. This approach can lead to simpler dependency management and improved security, making Deno a compelling choice for developers looking for a modern alternative to Node.js.
  • npm is the default package manager for Node.js, providing a vast ecosystem of libraries and tools for JavaScript development. While npm itself is not a runtime, it plays a crucial role in managing packages and dependencies for Node.js applications. Developers often rely on npm to install, update, and manage their project dependencies, making it an essential tool in the JavaScript ecosystem. For those who are already familiar with Node.js, npm remains a popular choice for managing packages and libraries.

FAQ on Branding

Is it "npm" or "NPM" or "Npm"?

npm should never be capitalized unless it is being displayed in a location that is customarily all-capitals (ex. titles on man pages).

Is "npm" an acronym for "Node Package Manager"?

Contrary to popular belief, npm is not in fact an acronym for "Node Package Manager"; It is a recursive bacronymic abbreviation for "npm is not an acronym" (if the project was named "ninaa", then it would be an acronym). The precursor to npm was actually a bash utility named "pm", which was the shortform name of "pkgmakeinst" - a bash function that installed various things on various platforms. If npm were to ever have been considered an acronym, it would be as "node pm" or, potentially "new pm".
