How to list all the Node.js modules I have linked with npm

Question

I am looking for a command that will list the names of global modules that I have npm link'd to local copies, also listing the local path.

In fact, a list of all globally installed modules would be even better, with the npm link'd ones flagged somehow.

Answer 1

To list all globally linked modules, this works (documentation https://docs.npmjs.com/cli/ls):

npm ls -g --depth=0 --link=true

I had to update the version of npm on my machine first, though:

npm install npm@latest -g

Answer 2

Did you try just listing the node_modules directory contents (e.g., ls -l node_modules | grep ^l)? They're normal symbolic links.

If you really need to find all symbolic links, you could try something like find / -type d -name "node_modules" 2>/dev/null | xargs -I{} find {} -type l -maxdepth 1 | xargs ls -l.

Answer 3

This command is simpler as of npm 7:

npm ls --link --global

Credit to Andrew for finding the --link flag

Answer 4

A better alternative to parsing ls is to use find like this:

find . -type l

You can use -maxdepth 1 to only process the first directory level:

find . -maxdepth 1 -type l

You can use -ls for additional information.

For instance, for finding Node.js modules that are npm linked:

find node_modules -maxdepth 1 -type l -ls

Here's an article why parsing ls is not the best idea.

Answer 5

If you want a nice colored output from npm list, you may like:

\ls -F node_modules | sed -n 's/@$//p' | xargs npm ls -g --depth 0

which gives in my current playground directory:

+-- [email protected]
+-- [email protected]
+-- [email protected]
+-- [email protected]
+-- [email protected]
+-- [email protected]
+-- [email protected]
`-- [email protected]

It makes a few assumptions, but it should work in most cases, or be easy to adapt with the explanations below.

• use \ls to bypass possible aliases on your ls command
• the -F option adds an '@' indicator for links
• the sed command selects those links and removes the indicator
• the xargs part passes previous output as arguments to npm ...
• npm is invoked with
  • list or ls to list modules with versions
  • replace with ll to get details about each listed module.
  • -g for the global modules and
  • --depth 0 for a shallow listing (optional)
  • --long false (default with 'list').

Issue: for some reason npm gives extraneous entries for me at the moment (non colored). They would be those I had "npm unlink"ed.

For "a list of all globally installed modules" in current npm path, you just do

npm list -g

For further needs you may want to have a look at

npm help folders

You cannot follow symlinks backwards unless you scan your whole filesystem and (then that's not a npm specific question).

For quickly finding files and directories by name, I use locate which works on an index rebuilt usually once a day.

locate '*/node_modules'

and start working from there (you may want to refine the search with --regexp option.

Answer 6

Use

find `npm root -g` -maxdepth 2 -type l

to show global links, including namespaced packages.

Andrew's answer works some of the time:

npm ls -g --depth=0 --link=true

But it blew up on peer dependency errors for me on some occasions.

Answer 7

I made a Node.js module, symlinked, that uses fs to check for symbolic links made by npm link or otherwise.

var symlinked = require("symlinked")

console.log(symlinked.names())

Answer 8

I found this question after I also wrote my own tool, and here it is for completeness: npm-list-linked.

It will recursively follow all linked packages down in the hierarchy as well. At my work we sometimes may have npm link 2-3 levels deep and this way you can see exactly which are local and which ones are not. It avoids surprises.

npm-list-linked

Output:

Linked packages in /home/user/projects/some-project/
    @prefix/package 0.2.7
        other-package 0.1.2

Answer 9

I see myself and others having this same question a lot. I wrote a small CLI for myself called link-status to display this info, and it may help others out too! Check it out here!

Answer 10

On Windows you can just look at the directory:

C:\Users\[username]\AppData\Roaming\npm\node_modules

You should see any of the symbolic linked libraries listed there, along side any global library installs.
