To unpublish a single package version, run npm unpublish <package_name>@<version> . If all the versions of a package can be unpublished, you can unpublish all versions at once by running npm unpublish <package_name> --force .
Node Packaged Modulesnpm can install packages in local or global mode. In local mode, it installs the package in a node_modules folder in your parent working directory. This location is owned by the current user.
Summary
- Use the npm list to show the installed packages in the current project as a dependency tree.
- Use npm list --depth=n to show the dependency tree with a specified depth.
- Use npm list --prod to show packages in the dependencies .
- Use npm list --dev to show packages in the devDependencies .
Description. This uninstalls a package, completely removing everything npm installed on its behalf. In global mode (ie, with -g or --global appended to the command), it uninstalls the current package context as a global package.
Install Package GloballyNPM can also install packages globally so that all the node. js application on that computer can import and use the installed packages. NPM installs global packages into /<User>/local/lib/node_modules folder. Apply -g in the install command to install package globally.
Updating local packages
- Navigate to the root directory of your project and ensure it contains a package.json file: cd /path/to/project.
- In your project root directory, run the update command: npm update.
- To test the update, run the outdated command. There should not be any output. npm outdated.
“how to uninstall react js” Code Answer

yarn remove <package>Running yarn remove foo will remove the package named foo from your direct dependencies updating your package. json and yarn. lock files in the process. Other developers working on the project can run yarn install to sync their own node_modules directories with the updated set of dependencies.
Yarn can consume the same package. json format as npm, and can install any package from the npm registry. However, you will not be able to take advantage of the Yarn. lock generated by Yarn, because (as the name suggests) it's only supported by Yarn, and npm shrinkwrap is not compatible.
Comparing Yarn vs NPM speed, yarn is the clear winner. Both Yarn and NPM download packages from the npm repository, using yarn add vs npm install command. However, Yarn is much faster than NPM as it installs all the packages simultaneously. It also cashes every download avoiding the need to re-install packages.
npm:
npm yet doesn't has a 'why' functionality built in.
yarn:
Yarn comes
with a 'why' command that tells why a dependency is present
in the project. For example, it is a dependency, a native module, or a project dependency.
Commands changed in yarn after npm.
| command | npm | yarn |
|---|
| Install dependencies | npm install | yarn |
On the other hand, Yarn installs those files which are only from the yarn. lock or package. json files. Therefore it has been deemed as more secured than npm packages.
yarn install is used to install all dependencies for a project. These have been replaced by yarn add and yarn add --dev. For more information, see the yarn add documentation. Running yarn with no command will run yarn install, passing through any provided flags.

- Remove yarn.
- Remove folder node_modules.
- In package.
- Remove all global package of yarn (don't need to remove if you want to use npm for one project)
- Remove yarn if you don't want to use it again.
- Install npm (if you installed, ignore this step)
- Install global and local package you need.
It can also contain other metadata such as a project description, the version of the project in a particular distribution, license information, even configuration data - all of which can be vital to both npm and to the end users of the package. The package. json file is normally located at the root directory of a Node.
You can also specify packages from different locations:
- yarn add package-name installs the package from the npm registry unless you have specified another one in your package.
- yarn add file:/path/to/local/folder installs a package that is on your local file system.
- yarn add file:/path/to/local/tarball.
npm install downloads a package and it's dependencies. npm install can be run with or without arguments. When run without arguments, npm install downloads dependencies defined in a package. json file and generates a node_modules folder with the installed modules.
There is no difference since "npm i" is an alias for "npm install" or "npm i" is the in short term of "npm install". Meaning it is just another name for the command. They both do the exact same thing (install or update all the dependencies in your package-lock.
npm install installs all modules that are listed on package. json file and their dependencies. npm update updates all packages in the node_modules directory and their dependencies. npm install express installs only the express module and its dependencies.
Wrap up
- Use npm outdated to discover dependencies that are out of date.
- Use npm update to perform safe dependency upgrades.
- Use npm install <packagename>@latest to upgrade to the latest major version of a package.
- Use npx npm-check-updates -u and npm install to upgrade all dependencies to their latest major versions.

npm ci (named after Continuous Integration) installs dependencies directly from package-lock. json and uses package. json only to validate that there are no mismatched versions. If any dependencies are missing or have incompatible versions, it will throw an error.
Updating your published package version number
- To change the version number in package.json , on the command line, in the package root directory, run the following command, replacing <update_type> with one of the semantic versioning release types (patch, major, or minor): npm version <update_type>
- Run npm publish .
You can install an old version of an npm package using the @ syntax:
- npm install <package>@<version>
- npm install cowsay.
- npm install cowsay@1.2.0.
- npm install -g webpack@4.16.4.
NPM offers the outdated command to print a list of packages which are out of date. npm outdated. The list of outdated packages includes the currently installed version, the wanted version defined within your package. json file and the latest stable version of the module.
?? Solution
- Delete your package-lock. json file or for yarn users, delete your yarn. lock file.
- So a better solution here would be to only delete the lines corresponding to the vulnerable package in your package-lock. json(or yarn. lock) file.
- Run npm install again.
On most systems, this is /usr/local . On Windows, it's %AppData%npm . On Unix systems, it's one level up, since node is typically installed at {prefix}/bin/node rather than {prefix}/node.exe . When the global flag is set, npm installs things into this prefix.
Clear the npm cache using npm cache clean or delete the modules from your node_modules directory. Turn off your wifi/kill your network connection. Try running that npm install again. Everything should install correctly through the local-npm cache without hitting the network at all.
The n command for installing and activating a version of Node is simple: n 6.17. 1 . You could also use n latest for the latest version of Node or n lts for the latest LTS version of Node. If the version of Node is already installed, then n will simply switch to that version.
Node. js is primarily used for non-blocking, event-driven servers, due to its single-threaded nature. It's used for traditional web sites and back-end API services, but was designed with real-time, push-based architectures in mind.
How to Install Node.js and NPM on Windows
- Step 1: Download Node. js Installer. In a web browser, navigate to
- Step 2: Install Node. js and NPM from Browser.
- Step 3: Verify Installation. Open a command prompt (or PowerShell), and enter the following: node –v.
When you are working on a JavaScript project, you can use npm to install other people's code packages into your own project. Your project might be a web project like a website or web app, or it could be a server-side project using node. Any JavaScript project can use npm to pull in packages of existing code.
package-lock. json is automatically generated for any operations where npm modifies either the node_modules tree, or package. json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.
