Package Exports

npm-cache-env

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (npm-cache-env) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

npm-cache-env

Get the path of npm cache folder from environment variables

// NPM_CONFIG_CACHE=/foo/bar node ./example.js
const npmCacheEnv = require('npm-cache-env');

npmCacheEnv(); //=> '/foo/bar'

Installation

Use npm.

npm install npm-cache-env

API

const npmCacheEnv = require('npm-cache-env');

npmCacheEnv()

Return: String or null

It finds an environment variable corresponding to the cache config of npm CLI:

https://docs.npmjs.com/misc/config#environment-variables

Any environment variables that start with npm_config_ will be interpreted as a configuration parameter. For example, putting npm_config_foo=bar in your environment will set the foo configuration parameter to bar.

If the cache config parameter doesn't exist in the environment variables, it returns null.

const npmCacheEnv = require('npm-cache-env');

// Npm_Config_Cache=/User/shinnn node ./example.js
npmCacheEnv(); //=> '/User/shinnn'

// node ./example.js
npmCacheEnv(); //=> null

The resultant path always becomes absolute.

const npmCacheEnv = require('npm-cache-env');

// npm_config_cache=123 node ./example.js
npmCacheEnv(); //=> '/path/to/current/working/directory/123'
