npm install foo@next

The package.json and semver docs don't mention next.

Javascript Solutions

Solution 1 - Javascript

next is a version or tag published in your reference npm registry

npm install installs a package.

A package is:

d) a <name>@<version> that is published on the registry (see npm-registry) with (c)
e) a <name>@<tag> (see npm-dist-tag) that points to (d)

You can view the version that each dist-tag points to by running the following commands:

npm view <package_name> dist-tags
npm dist-tags ls <package_name>

e.g. for the react npm package:

npm view react dist-tags


  latest: '17.0.2',
  next: '18.0.0-rc.0-next-3dc41d8a2-20211223',
  experimental: '0.0.0-experimental-3dc41d8a2-20211223',
  beta: '18.0.0-beta-24dd07bd2-20211208',
  rc: '18.0.0-rc.0'


Solution 2 - Javascript

Next is tag. look at the below possible commands.

> A tag can be used when installing packages as a reference to a version instead of using a specific version number:

npm install [<@scope>/]<name>
npm install [<@scope>/]<name>@<tag>
npm install [<@scope>/]<name>@<version>
npm install [<@scope>/]<name>@<version range>

How its added in package? See dist-tag

npm dist-tag add <pkg>@<version> [<tag>]
npm dist-tag rm <pkg> <tag>
npm dist-tag ls [<pkg>]

Check - https://docs.npmjs.com/cli/dist-tag

Solution 3 - Javascript

Appending the @next tag to the package name installs the upcoming version, which is likely unstable.

From npm docs for npm-dist-tag:

> Tags can be used to provide an alias instead of version numbers. > > For example, a project might choose to have multiple streams of > development and use a different tag for each stream, e.g., stable, > beta, dev, canary. > > By default, the latest tag is used by npm to identify the current > version of a package, and npm install (without any @ or > @ specifier) installs the latest tag. Typically, projects only > use the latest tag for stable release versions, and use other tags for > unstable versions such as prereleases. > > The next tag is used by some projects to identify the upcoming > version. > > Other than latest, no tag has any special significance to npm itself.
