npm link (in package folder)
npm link <pkgname>
npm ln (with any of the previous argument usage)
DESCRIPTIONPackage linking is a two-step process.
First, npm link in a package folder will create a globally-installed symbolic link from prefix/package-name to the current folder.
Next, in some other location, npm link package-name will create a symlink from the local node_modules folder to the global symlink.
Note that package-name is taken from package.json, not from directory name.
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/redis/
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 redis
That is, it first creates a global link, and then links the global installation target into your project's node_modules folder.
