npm link (in package dir) npm link [<@scope>/]<pkg>[@<version>] alias: npm ln
Package linking is a two-step process.
npm link in a package folder will create a globally-installed
symbolic link from
prefix/package-name to the current folder (see
npm-config for the value of
Next, in some other location,
npm link package-name will create a
symlink from the local
node_modules folder to the global symlink.
package-name is taken from
not from directory name.
The package name can be optionally prefixed with a scope. See
The scope must be preceded by an @-symbol and followed by a slash.
When creating tarballs for
npm publish, the linked packages are
"snapshotted" to their current state by resolving the symbolic links.
This is handy for installing your own stuff, so that you can work on it and test it iteratively without having to continually rebuild.
cd ~/projects/node-redis # go into the package directory npm link # creates global link cd ~/projects/node-bloggy # go into some other package directory. npm link redis # link-install the package
Now, any changes to ~/projects/node-redis will be reflected in ~/projects/node-bloggy/node_modules/node-redis/. Note that the link should be to the package name, not the directory name for that package.
You may also shortcut the two steps in one. For example, to do the above use-case in a shorter way:
cd ~/projects/node-bloggy # go into the dir of your main project npm link ../node-redis # link the dir of your dependency
The second line is the equivalent of doing:
(cd ../node-redis; npm link) npm link node-redis
That is, it first creates a global link, and then links the global
installation target into your project's
If your linked package is scoped (see
npm-scope) your link command must
include that scope, e.g.
npm link @myorg/privatepackage
