Usage
To get all entry-points for a package located at ./node_modules/my-package:
import { getPackageEntryPoints } from 'pkg-entry-points'
const packageExports = await getPackageEntryPoints('./node_modules/my-package')
console.log(packageExports)
/*
{
'.': [
[conditions, internalPath],
],
'./entry-file': [
[['types'], './dist/entry-file.d.ts'],
[['import'], './dist/entry-file.mjs'],
[['require'], './dist/entry-file.js'],
],
...,
}
*/
Example: vue - using exports conditions

API
getPackageEntryPoints(packagePath, fs?)
Returns: Promise<PackageEntryPoints>
Type definitions:
type PackageEntryPoints = {
[subpath: string]: ConditionToPath[]
}
type ConditionToPath = [conditions: string[], internalPath: string]
Description
Returns all possible entry-points of an npm package.
If the package has a package.json#exports property, it will return an object where the keys are expanded subpaths and the values are arrays of tuples containing an array of possible import combinations paired with the internal file path it resolves to.
If the package does not have an exports property, it will return an object where the keys are the internal file paths, mapping to arrays of possible import combinations.
Parameters
packagePathType:
stringRequired
The path to the package to get the exports for.
fsType:
typeof import('fs/promises')Optional
Default:
fs.promisesThe file-system to use. Defaults to Node.js's
fs/promisesmodule.
