In order to distinguish between this and other options, the argument must start with " or " Example:ĭo a install, where is the "tag" config. The package must contain a package.json file with name and version properties.įetch the tarball url, and then install it.npm strips one directory layer when installing the package (an equivalent of tar x -strip-components=1 is run). The package contents should reside in a subfolder inside the tarball (usually it is called package/).Note: if you just want to link a dev directory into your npm root, you can do this more easily by using npm link. Install a package that is sitting on the filesystem. If sits inside the root of your project, its dependencies may be hoisted to the toplevel node_modules as they would for other types of dependencies. Its dependencies will be installed before it's linked. Install the package in the directory as a symlink in the current project. NOTE: The -production flag has no particular meaning when adding a dependency to a project. To install all modules listed in both dependencies and devDependencies when NODE_ENV environment variable is set to production, you can use -production=false. With the -production flag (or when the NODE_ENV environment variable is set to production), npm will not install modules listed in devDependencies. In global mode (ie, with -g or -global appended to the command), it installs the current package context (ie, the current working directory) as a global package.īy default, npm install will install all modules listed as dependencies in package.json. ![]() Install the dependencies in the local node_modules folder. Npm install (in package directory, no arguments): f) a that has a "latest" tag satisfying (e)Įven if you never publish your package, you can still get a lot of benefits of using npm if you just want to write a node program (a), and perhaps if you also want to be able to easily install it elsewhere after packing it up into a tarball (b).e) a (see npm dist-tag) that points to (d).d) a that is published on the registry (see registry) with (c).a) a folder containing a program described by a package.json file.See package-lock.json and npm shrinkwrap. If the package has a package-lock or shrinkwrap file, the installation of dependencies will be driven by that, with an npm-shrinkwrap.json taking precedence if both files exist. ![]() This command installs a package, and any packages that it depends on.
