local-pkg

What is local-pkg?

The 'local-pkg' npm package is designed to help developers manage and interact with local packages in a Node.js environment. It provides utilities to check for the existence of local packages, resolve their paths, and require them conditionally.

What are local-pkg's main functionalities?

Check if a local package exists

This feature allows you to check if a specific local package is installed. The function `isPackageExists` returns a boolean indicating the presence of the package.

const { isPackageExists } = require('local-pkg');

if (isPackageExists('some-local-package')) {
  console.log('Package exists');
} else {
  console.log('Package does not exist');
}

Resolve the path of a local package

This feature helps you resolve the absolute path of a local package. The function `resolvePackagePath` returns the path as a string.

const { resolvePackagePath } = require('local-pkg');

const packagePath = resolvePackagePath('some-local-package');
console.log(`Package path: ${packagePath}`);

Require a local package conditionally

This feature allows you to require a local package conditionally. The function `requireModule` attempts to require the package and returns it if successful, otherwise it returns `null`.

const { requireModule } = require('local-pkg');

const someLocalPackage = requireModule('some-local-package');
if (someLocalPackage) {
  console.log('Package loaded successfully');
} else {
  console.log('Failed to load package');
}

Other packages similar to local-pkg

resolve

The 'resolve' package is a library for resolving module paths in Node.js. It provides similar functionality to 'local-pkg' in terms of resolving paths but does not include utilities for checking package existence or conditional requiring.

pkg-up

The 'pkg-up' package finds the closest package.json file by traversing up from a specified directory. While it helps in locating package.json files, it does not offer the same comprehensive utilities for managing local packages as 'local-pkg'.

find-up

The 'find-up' package is used to find a file or directory by walking up parent directories. It can be used to locate package.json files but lacks the specific package management utilities provided by 'local-pkg'.
