Documented steps
From inside the package you want to develop on, run npm link (no args) to create a global symlink under the npm global prefix (check it with npm prefix -g)
This symlinks the package into {prefix}/lib/node_modules/<package> and links any bins into {prefix}/bin
From the consuming project directory, run npm link <package-name> where <package-name> is the package.json name (not the folder name)
For a scoped package use the slash form: npm link @myorg/privatepackage
One-step shortcut: from the consumer run npm link ../path/to/dep-folder (folder path here, not package name); it creates the global link then links it in
Changes in the linked package are reflected immediately in the consumer's node_modules
To persist the link in package.json, use npm link <dep> --save
Known gotchas
npm link resolves the package NAME from package.json, not from the directory name
Linked deps are NOT saved to package.json by default; if your package.json pins a semver like redis ^3.0.1, npm link redis can shift it to a file: spec (often unwanted) — use --save carefully
The one-step form refers to the directory path, while the two-step npm link <name> refers to the package name
Other developers won't have your symlink layout unless their folders match exactly
For monorepos prefer npm workspaces over npm link (install auto-links workspaces)
