SYNOPSIS
The name npm (Node Package Manager) stems from when npm first was created as a package manager for Node.js. All npm packages are defined in files called package.json. The content of package.json must be written in JSON. At least two fields must be present in the definition file: name and version. The easiest way to install a Node.js module locally is to use the npm install command in the folder containing your Cloud Function. For instance, the following command adds the uuid module: npm install uuid This combines two steps: It marks the latest version of the module as a dependency in your package.json file.

npx [options] <command>[@version] [command-arg].
npx [options] [-p|--package <pkg>]. <command> [command-arg].
npx [options] -c '<command-string>'
npx --shell-auto-fallback [shell]
INSTALL
npm install -g npx
DESCRIPTION
Executes
<command>
either from a local node_modules/.bin
, or from a central cache, installing any packages needed in order for <command>
to run.By default,
npx
will check whether <command>
exists in $PATH
, or in the local project binaries, and execute that. If <command>
is not found, it will be installed prior to execution.Unless a
--package
option is specified, npx
will try to guess the name of the binary to invoke depending on the specifier provided. All package specifiers understood by npm
may be used with npx
, including git specifiers, remote tarballs, local directories, or scoped packages.If a full specifier is included, or if
--package
is used, npx will always use a freshly-installed, temporary version of the package. This can also be forced with the --ignore-existing
flag.-p, --package <package>
- define the package to be installed. This defaults to the value of<command>
. This is only needed for packages with multiple binaries if you want to call one of the other executables, or where the binary name does not match the package name. If this option is provided<command>
will be executed as-is, without interpreting@version
if it's there. Multiple--package
options may be provided, and all the packages specified will be installed.--no-install
- If passed tonpx
, it will only try to run<command>
if it already exists in the current path or in$prefix/node_modules/.bin
. It won't try to install missing commands.--cache <path>
- set the location of the npm cache. Defaults to npm's own cache settings.--userconfig <path>
- path to the user configuration file to pass to npm. Defaults to whatever npm's current default is.-c <string>
- Execute<string>
inside annpm run-script
-like shell environment, with all the usual environment variables available. Only the first item in<string>
will be automatically used as<command>
. Any others must use-p
.--shell <string>
- The shell to invoke the command with, if any.--shell-auto-fallback [<shell>]
- Generates shell code to override your shell's 'command not found' handler with one that callsnpx
. Tries to figure out your shell, or you can pass its name (eitherbash
,fish
, orzsh
) as an option. See below for how to install.--ignore-existing
- If this flag is set, npx will not look in$PATH
, or in the current package'snode_modules/.bin
for an existing version before deciding whether to install. Binaries in those paths will still be available for execution, but will be shadowed by any packages requested by this install.-q, --quiet
- Suppressed any output from npx itself (progress bars, error messages, install reports). Subcommand output itself will not be silenced.-n, --node-arg
- Extra node argument to supply to node when binary is a node script. You can supply this option multiple times to add more arguments.-v, --version
- Show the current npx version.
EXAMPLES
Running a project-local bin
One-off invocation without local installation
Invoking a command from a github repository
Execute a full shell command using one npx call w/ multiple packages
Run node binary with --inspect
Specify a node version to run npm scripts (or anything else!)
SHELL AUTO FALLBACK
You can configure
npx
to run as your default fallback command when you type something in the command line with an @
but the command is not found. This includes installing packages that were not found in the local prefix either.For example:
Currently,
zsh
, bash
(>= 4), and fish
are supported. You can access these completion scripts using npx --shell-auto-fallback <shell>
.To install permanently, add the relevant line below to your
~/.bashrc
, ~/.zshrc
, ~/.config/fish/config.fish
, or as needed. To install just for the shell session, simply run the line.Bus Simulator is a driving game where you have to control a bus and you can play it online and for free on Silvergames.com.

When you install a package using
npm install <packagename>
, the latest available version of the package is downloaded and put in the node_modules
folder, and a corresponding entry is added to the package.json
and package-lock.json
files that are present in your current folder.npm calculates the dependencies and installs the latest available version of those as well.
Let's say you install
cowsay
, a cool command line tool that lets you make a cow say things.When you
npm install cowsay
, this entry is added to the package.json
file:Npm Dependency Version Syntax
and this is an extract of
package-lock.json
, where we removed the nested dependencies for clarity:Now those 2 files tell us that we installed version
1.3.1
of cowsay, and our rule for updates is ^1.3.1
, which for the npm versioning rules means that npm can update to patch and minor releases: 1.3.2
, 1.4.0
Omnisphere 2 keygen generator. and so on.If there is a new minor or patch release and we type
npm update
, the installed version is updated, and the package-lock.json
file diligently filled with the new version.package.json
remains unchanged.To discover new releases of the packages, you run
npm outdated
.Here's the list of a few outdated packages in one repository that wasn't updated for quite a while:
Some of those updates are major releases. Running
npm update
won't update the version of those. Major releases are never updated in this way because they (by definition) introduce breaking changes, and npm
wants to save you trouble.To update to a new major version all the packages, install the
npm-check-updates
package globally:then run it:
this will upgrade all the version hints in the
package.json
file, to dependencies
and devDependencies
, so npm can install the new major version.You are now ready to run the update:
Npm Install
If you just downloaded the project without the
node_modules
dependencies and you want to install the shiny new versions first, just run
