description: Handling Module Name Disputes
---

This document describes the steps that you should take to resolve module name
disputes with other npm publishers. It also describes special steps you should
take about names you think infringe your trademarks.

This document is a clarification of the acceptable behavior outlined in the
[npm Code of Conduct](https://www.npmjs.com/policies/conduct), and nothing in
this document should be interpreted to contradict any aspect of the npm Code of
Conduct.

### TL;DR

1. Get the author email with `npm owner ls <pkgname>`
2. Email the author, CC <support@npmjs.com>
3. After a few weeks, if there's no resolution, we'll sort it out.

Don't squat on package names.  Publish code or move out of the way.

### Description

There sometimes arise cases where a user publishes a module, and then later,
some other user wants to use that name. Here are some common ways that happens
(each of these is based on actual events.)

1. Alice writes a JavaScript module `foo`, which is not node-specific. Alice
   doesn't use node at all. Yusuf wants to use `foo` in node, so he wraps it in
   an npm module. Some time later, Alice starts using node, and wants to take
   over management of her program.
2. Yusuf writes an npm module `foo`, and publishes it. Perhaps much later, Alice
   finds a bug in `foo`, and fixes it. She sends a pull request to Yusuf, but
   Yusuf doesn't have the time to deal with it, because he has a new job and a
   new baby and is focused on his new Erlang project, and kind of not involved
   with node any more. Alice would like to publish a new `foo`, but can't,
   because the name is taken.
3. Yusuf writes a 10-line flow-control library, and calls it `foo`, and
   publishes it to the npm registry. Being a simple little thing, it never
   really has to be updated. Alice works for Foo Inc, the makers of the
   critically acclaimed and widely-marketed `foo` JavaScript toolkit framework.
   They publish it to npm as `foojs`, but people are routinely confused when
   `npm install foo` is some different thing.
4. Yusuf writes a parser for the widely-known `foo` file format, because he
   needs it for work. Then, he gets a new job, and never updates the prototype.
   Later on, Alice writes a much more complete `foo` parser, but can't publish,
   because Yusuf's `foo` is in the way.

1. `npm owner ls foo`. This will tell Alice the email address of the owner
   (Yusuf).
2. Alice emails Yusuf, explaining the situation **as respectfully as possible**,
   and what she would like to do with the module name. She adds the npm support
   staff <support@npmjs.com> to the CC list of the email. Mention in the email
   that Yusuf can run npm owner `add alice foo` to add Alice as an owner of the
   foo package.
3. After a reasonable amount of time, if Yusuf has not responded, or if Yusuf
   and Alice can't come to any sort of resolution, email support
   <support@npmjs.com> and we'll sort it out. ("Reasonable" is usually at least
   4 weeks.)

### Reasoning

In almost every case so far, the parties involved have been able to reach an
amicable resolution without any major intervention. Most people really do want
to be reasonable, and are probably not even aware that they're in your way.

Module ecosystems are most vibrant and powerful when they are as self-directed
as possible. If an admin one day deletes something you had worked on, then that
is going to make most people quite upset, regardless of the justification. When
humans solve their problems by talking to other humans with respect, everyone
has the chance to end up feeling good about the interaction.

### Exceptions

Some things are not allowed, and will be removed without discussion if they are
brought to the attention of the npm registry admins, including but not limited
to:

1. Malware (that is, a package designed to exploit or harm the machine on which
   it is installed).
2. Violations of copyright or licenses (for example, cloning an MIT-licensed
   program, and then removing or changing the copyright and license statement).
3. Illegal content.
4. "Squatting" on a package name that you plan to use, but aren't actually
   using. Sorry, I don't care how great the name is, or how perfect a fit it is
   for the thing that someday might happen. If someone wants to use it today,
   and you're just taking up space with an empty tarball, you're going to be
   evicted.
5. Putting empty packages in the registry. Packages must have SOME
   functionality. It can be silly, but it can't be nothing. (See also:
   squatting.)
6. Doing weird things with the registry, like using it as your own personal
   application database or otherwise putting non-packagey things into it.
7. Other things forbidden by the npm
   [Code of Conduct](https://www.npmjs.com/policies/conduct) such as hateful
   language, pornographic content, or harassment.

If you see bad behavior like this, please report it to <abuse@npmjs.com> right
away. **You are never expected to resolve abusive behavior on your own. We are
here to help.**

### Trademarks

If you think another npm publisher is infringing your trademark, such as by
using a confusingly similar package name, email <abuse@npmjs.com> with a link to
the package or user account on [https://www.npmjs.com/](https://www.npmjs.com/).
Attach a copy of your trademark registration certificate.

If we see that the package's publisher is intentionally misleading others by
misusing your registered mark without permission, we will transfer the package
name to you. Otherwise, we will contact the package publisher and ask them to
clear up any confusion with changes to their package's `README` file or
metadata.
