path-env

Manipulate $PATH-like environment variable

Requirements

• Node.js ≥ 8.9.0

Usage

NOTE:

• Everything is chainable.

Modifying $PATH and get its value

import {pathString} from 'path-env'

const path = pathString()
  .append(['/append/bin'])
  .prepend(['/prepend/bin'])
  .surround(['/surround/bin'])
  .get.string()

console.log(path)

This will print /surround/bin:/prepend/bin:...:/append/bin:/surround/bin in POSIX systems.

Modifying a $PATH-like and get its value

Modifying $NODE_PATH.

import {pathString} from 'path-env'

const path = pathString('NODE_PATH')
  .append(['/append/node_modules'])
  .prepend(['/prepend/node_modules'])
  .surround(['/surround/node_modules'])
  .get.string()

console.log(path)

This will print /surround/node_modules:/prepend/node_modules:...:/append/node_modules:/surround/node_modules in POSIX systems.

Modifying $PATH-like property of env object

You can also modify $PATH-like value directly from an env-like object.

Signature:

import {pathEnv} from 'path-env'

const env = pathEnv() // equivalent to `const env = pathEnv(process.env, 'PATH')`
  .path.append(['/append/bin'])
  .path.prepend(['/prepend/bin'])
  .path.surround(['/surround/bin'])
  .get.env()

console.log(env)

Result: env will looks exactly like process.env except modified PATH property.
