NPM Commands

NPM Commands:-

Command Name Definition
npm-access Access controls are set for private packages using this method.

Example:- Click

npm-adduser Create or verify a user named <username> in the specified registry, and save the credentials in the .npmrc file. If no registry is specified, the default registry will be used (see config).

Example:- Click

npm-audit Using the audit command, you will submit a description of the dependencies configured in your project to your default registry and ask for a report of known vulnerabilities. The report will contain instructions on how to act on the information. The command will exit with a 0 exit code if there are no known vulnerabilities.

Example:- Click

npm-bin Print the folder where npm will install executables.

Example:- Click

npm-bugs This command attempts to guess the likely URL of a package’s bug tracker and then attempts to open the bug tracker using the –browser parameter. If a package name is not provided, the command searches for the package.json in the current folder and uses the name property.

Example:- Click

npm-build It is called by npm link and npm install. It should generally be run during installation, but if you need to run it directly, run

Example:- Click

npm-bundle Because the default behavior is now to install packages into the local space, the npm bundle command has been removed in version 1.0.

Example:- Click

npm-cache This command is primarily intended to be used internally by npm, but it can also be used explicitly to add data to the installation cache. clean: Delete all the data in the cache folder. verify: Verify the contents of the cache folder.

Example:- Click

npm-doctor npm doctor runs a series of checks to make sure that your npm installation is properly set up to manage your JavaScript packages. npm is mostly a standalone tool, but it does have some basic requirements:

Example:- Click

npm-edit Selects a (sub)dependency in the current working directory and opens the package folder in the default editor (or whatever you’ve configured as the npm editor config – see npm-config.)After it has been edited, the package is rebuilt so as to pick up any changes in compiled packages. For instance, you can do npm install to connect to install connect into your package, and then npm edit connect to make a few changes to your locally installed copy.
