pnpm.installPkgs(pkgsToInstall, [options])

Install packages.

Arguments:

• pkgsToInstall - Object | String[] - either an object that maps package names to version ranges or inputs usually passed to npm install (e.g., foo@1.0.0, foo).
• options.save - Boolean - package will appear in dependencies.
• options.saveDev - Boolean - package will appear in devDependencies.
• options.saveOptional - Boolean - package will appear in optionalDependencies.
• options.saveExact - Boolean - saved dependencies will be configured with an exact version rather than using npm's default semver range operator.
• options.global - Boolean - the packages will be installed globally rather than locally.
• options.cwd - String - the directory in which the installation will be performed. By default the process.cwd() value is used.
• options.quiet - Boolean - false by default. No output to the console.
• options.metaCache - Map - a cache for package meta info.
• options.networkConcurrency - Number - 16 by default. Max amount of network requests to perform concurrently.

  'hello-world': '^2.3.1'
}, { save: true, quiet: true })

pnpm.install([options])

Install all modules listed as dependencies in package.json.

Arguments: (same as in named install and additionally)

pnpm.uninstall(pkgsToUninstall, [options])

Uninstalls a package, completely removing everything pnpm installed on its behalf.

Arguments:

• pkgsToUninstall - String[] - the package names to be uninstalled.
• options.save - Boolean - the package will be removed from dependencies.
• options.saveDev - Boolean - the package will be removed from devDependencies.
• options.saveOptional - Boolean - the package will be removed from optionalDependencies.
• options.global - Boolean - the packages will be uninstalled globally.

pnpm.link(linkFrom, lintTo, [options])

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

Arguments:

• lintTo - String - path to the dependent package.

pnpm.linkToGlobal(linkFrom, [options])

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

Arguments:

Create a symbolic link from the global pkgName to the linkTo/node_modules folder.

Arguments:

• pkgName - String - package to link.
• linkTo - String - package to link to.

pnpm.prune([options])
