@pnpm/core

Fast, disk space efficient installation engine. Used by pnpm

Install

Install it via npm.

pnpm add @pnpm/core

It also depends on @pnpm/logger version 1, so install it as well via:

pnpm add @pnpm/logger@1

API

mutateModules(importers, options)

TODO

link(linkFromPkgs, linkToModules, [options])

Create symbolic links from the linked packages to the target package's node_modules (and its node_modules/.bin).

Arguments:

• linkFromPkgs - String[] - paths to the packages that should be linked.
• linkToModules - String - path to the dependent package's node_modules directory.
• options.reporter - Function - A function that listens for logs.

linkToGlobal(linkFrom, options)

Create a symbolic link from the specified package to the global node_modules.

Arguments:

• linkFrom - String - path to the package that should be linked.
• globalDir - String - path to the global directory.
• options.reporter - Function - A function that listens for logs.

linkFromGlobal(pkgNames, linkTo, options)

Create symbolic links from the global pkgNames to the linkTo/node_modules folder.

Arguments:

• pkgNames - String[] - packages to link.
• linkTo - String - package to link to.
• globalDir - String - path to the global directory.
• options.reporter - Function - A function that listens for logs.

storeStatus([options])

Return the list of modified dependencies.

Arguments:

• options.reporter - Function - A function that listens for logs.

Returns: Promise<string[]> - the paths to the modified packages of the current project. The paths contain the location of packages in the store, not in the projects node_modules folder.

storePrune([options])

Remove unreferenced packages from the store.

Hooks

Hooks are functions that can step into the installation process.

readPackage(pkg: Manifest): Manifest | Promise<Manifest>

This hook is called with every dependency's manifest information. The modified manifest returned by this hook is then used by @pnpm/core during installation. An async function is supported.

Example:

const { installPkgs } = require('@pnpm/core')

installPkgs({
  hooks: {readPackage}
})

function readPackage (pkg) {
  if (pkg.name === 'foo') {
    pkg.dependencies = {
      bar: '^2.0.0',
    }
  }
  return pkg
}

afterAllResolved(lockfile: Lockfile): Lockfile | Promise<Lockfile>

This hook is called after all dependencies are resolved. It receives and returns the resolved lockfile object. An async function is supported.
