ls-exports

Given a package name and a version number, or a path to a package.json, what specifiers does it expose?

The package export defaults an async function. It fulfills with an object with the following keys:

name the package name
version: the package version
engines: the package's engines requirements
binaries: the files that are made available as executable programs
errors: any validation errors encountered during parsing. _{Note that these errors do not necessarily interfere with the listed entry points being accessible at runtime.}

For ESM-supporting node versions (at the time of this writing, ^12.17 || >= 13.2):

require: valid specifiers to pass into require
import: valid specifiers to pass into import(), or to use in a static import statement
files: all files on the filesystem that are directly exposed by the above entry points
tree: a hierarchical object structure where each directory is represented as a key containing an object, and each file is represented as a key containing a list of the entry points that expose that file

For node versions prior to ESM support (at the time of this writing, < 12.17 || ~13.0 || ~13.1):

require (pre-exports): valid specifiers to pass into require
files (pre-exports): all files on the filesystem that are directly exposed by the above entry points
tree (pre-exports): a hierarchical object structure where each directory is represented as a key containing an object, and each file is represented as a key containing a list of the entry points that expose that file

Example

ls-exports package resolve@1
