yarn info

See information related to packages.

Examples

yarn info lodash

Details

This command prints various information related to the specified packages, accepting glob patterns.

By default, if the locator reference is missing, Yarn will default to print the information about all versions of the package in the active workspace dependency tree. To instead print all versions of the package in the whole project, use the -A,--all flag.

Some fields will be hidden by default in order to keep the output readable, but can be selectively displayed by using additional options:

  • The --dependents flag will print all dependents for each matching package.

  • The --manifest flag will print data obtained by looking at the package archive (license, homepage, ...).

  • The --virtuals flag will print each instance of the virtual packages.

Note that this command will only print the information directly related to the selected packages - if you wish to know why the package is there in the first place, use yarn why which will do just that (it also provides a -R,--recursive flag that may be of some help).
