What specific version is indicated by the @next tag for npm packages?

Which version of the foo package will be installed by running this command?

npm install foo@next

Neither the package.json nor the semver documentation make reference to the use of next.

Answer №1

next represents a specific version or tag available in your chosen npm registry.

npm install is used to add a package to your project.

A package can be defined as:

...
d) a <name>@<version> that has been officially published on the registry (refer to npm-registry) with (c)
e) a <name>@<tag> (check npm-dist-tag) that points to (d)
...

To check which versions each dist-tag directs to, use the following commands:

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

For example, for the react npm package:

npm view react dist-tags

Result:

{
  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'
}

Reference

Answer №2

Up next is the tag. Take a look at the various commands available below.

A tag can serve as a reference when installing packages instead of specifying a specific version number:

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

Wondering how it's added to the package? Check out dist-tag

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

Answer №3

When you append the @next tag to a package name, you are installing a version that is still in development and may be unstable.

According to the npm documentation on npm-dist-tag:

Tags can act as aliases for version numbers.

For instance, a project might have different tags for various development stages like stable, beta, dev, or canary.

By default, npm uses the latest tag to install the most recent version of a package. Running `npm install` without specifying any @ symbol will install the latest tag. Typically, projects reserve the latest tag for stable releases, while using other tags for versions that are less stable, like prereleases.

The next tag is often used to indicate the upcoming version of a project.

Aside from latest, no other tag holds special meaning within npm itself.
