Introduction to npm

npm is the standard package manager for Node.js. In September 2022 over 2.1 million packages were reported being listed in the npm registry, making it the biggest single language code repository on Earth, and you can be sure there is a package for (almost!) everything.

What is one way to install npm packages : To publish and install packages to and from the public npm registry or a private npm registry, you must install Node.js and the npm command line interface using either a Node version manager or a Node installer. We strongly recommend using a Node version manager like nvm to install Node.js and npm.

Reinstall all npm packages

  1. To force this behavior, start by deleting the node_modules directory within the project:
  2. Then run the install command to reinstall the packages in a new node_modules folder:
  3. The install command creates the node_modules within your current directory and downloads the package to the project.


Yes, it is possible to install multiple packages using apt-get at the same time. This can be done by listing the package names separated by a space after the "apt-get install" command.

What to download for npm

To publish and install packages to and from the public npm registry or a private npm registry, you must install Node.js and the npm command line interface using either a Node version manager or a Node installer. We strongly recommend using a Node version manager like nvm to install Node.js and npm.The npm modules are first downloaded here and then copied to npm global folder ( %AppData%/Roaming/npm on Windows) or project specific folder ( your-project/node_modules ). In earlier versions of NPM modules were always placed in /usr/local/lib/node or wherever you specified the npm root within the . npmrc file.Installing “globally” means the package is installed in the npm root directory. Typically, globally installed packages are executables, so npm usually creates a shortcut/shim so the package is available on your PATH (i.e. you can run the command anywhere)

All the packages should be installed locally.

If the package is installed globally, then that package can't have different versions for different applications. By installing the package locally, we can ensure that each program can have its local package of the desired version.

Do I need to install npm packages for every project : No, you don't need to install NPM (Node Package Manager) for every project. Once NPM is installed on your system, you can use it for multiple projects without reinstalling it each time. However, for each project, you may need to initialize a `package.

What is the most downloaded package in npm : The most popular NPM list package is Async or Asynchronous. It is widely used in Node js to simplify managing asynchronous programming and enable developers to write cleaner code and identify patterns. It can handle complex workflow, including numerous asynchronous tasks like callbacks and promises.
