Synopsis

npm publish<package-spec>

Description

Publishes a package to the registry so that it can be installed by name.

By default npm will publish to the public registry. This can be overridden by specifying a different default registry or using ascope in the name, combined with a scope-configured registry (seepackage.json).

Apackage is interpreted the same way as other commands (likenpm install) and can be:

a) a folder containing a program described by apackage.json file
b) a gzipped tarball containing (a)
c) a url that resolves to (b)
d) a<name>@<version> that is published on the registry (seeregistry) with (c)
e) a<name>@<tag> (seenpm dist-tag) that points to (d)
f) a<name> that has a "latest" tag satisfying (e)
g) a<git remote url> that resolves to (a)

The publish will fail if the package name and version combination already exists in the specified registry.

Once a package is published with a given name and version, that specific name and version combination can never be used again, even if it is removed withnpm unpublish.

As ofnpm@5, both a sha1sum and an integrity field with a sha512sum of the tarball will be submitted to the registry during publication. Subsequent installs will use the strongest supported algorithm to verify downloads.

Similar to--dry-run seenpm pack, which figures out the files to be included and packs them into a tarball to be uploaded to the registry.

Files included in package

To see what will be included in your package, runnpm pack --dry-run. All files are included by default, with the following exceptions:

Certain files that are relevant to package installation and distribution are always included. For example,package.json,README.md,LICENSE, and so on.
If there is a "files" list inpackage.json, then only the files specified will be included. (If directories are specified, then they will be walked recursively and their contents included, subject to the same ignore rules.)
If there is a.gitignore or.npmignore file, then ignored files in that and all child directories will be excluded from the package. Ifboth files exist, then the.gitignore is ignored, and only the.npmignore is used.
.npmignore files follow thesame pattern rules as.gitignore files
If the file matches certain patterns, then it willnever be included, unless explicitly added to the"files" list inpackage.json, or un-ignored with a! rule in a.npmignore or.gitignore file.
Symbolic links are never included in npm packages.

Seedevelopers for full details on what's included in the published package, as well as details on how the package is built.

Configuration

`tag`

Default: "latest"
Type: String

If you ask npm to install a package and don't tell it a specific version, then it will install the specified tag.

It is the tag added to the package@version specified in thenpm dist-tag add command, if no explicit tag is given.

When used by thenpm diff command, this is the tag used to fetch the tarball that will be compared with the local files by default.

If used in thenpm publish command, this is the tag that will be added to the package submitted to the registry.

`access`

Default: 'public' for new packages, existing packages it will not change the current level
Type: null, "restricted", or "public"

If you do not want your scoped package to be publicly viewable (and installable) set--access=restricted.

Unscoped packages can not be set torestricted.

Note: This defaults to not changing the current access level for existing packages. Specifying a value ofrestricted orpublic during publish will change the access for an existing package the same way thatnpm access set status would.

`dry-run`

Default: false
Type: Boolean

Indicates that you don't want npm to make any changes and that it should only report what it would have done. This can be passed into any of the commands that modify your local installation, eg,install,update,dedupe,uninstall, as well aspack andpublish.

Note: This is NOT honored by other network related commands, egdist-tags,owner, etc.

`otp`

Default: null
Type: null or String

This is a one-time password from a two-factor authenticator. It's needed when publishing or changing package permissions withnpm access.

If not set, and a registry response fails with a challenge for a one-time password, npm will prompt on the command line for one.

`workspace`

Default:
Type: String (can be set multiple times)

Enable running a command in the context of the configured workspaces of the current project while filtering by running only the workspaces defined by this configuration option.

Valid values for theworkspace config are either:

Workspace names
Path to a workspace directory
Path to a parent workspace directory (will result in selecting all workspaces within that folder)

When set for thenpm init command, this may be set to the folder of a workspace which does not yet exist, to create the folder and set it up as a brand new workspace within the project.

This value is not exported to the environment for child processes.

`workspaces`

Default: null
Type: null or Boolean

Set to true to run the command in the context ofall configured workspaces.

Explicitly setting this to false will cause commands likeinstall to ignore workspaces altogether. When not set explicitly:

Commands that operate on thenode_modules tree (install, update, etc.) will link workspaces into thenode_modules folder. - Commands that do other things (test, exec, publish, etc.) will operate on the root project,unless one or more workspaces are specified in theworkspace config.

This value is not exported to the environment for child processes.

`include-workspace-root`

Default: false
Type: Boolean

Include the workspace root when workspaces are enabled for a command.

When false, specifying individual workspaces via theworkspace config, or all workspaces via theworkspaces flag, will cause npm to operate only on the specified workspaces, and not on the root project.

This value is not exported to the environment for child processes.
