Nommer - Lib

Install, remove and check existence of node_modules

Getting Started

Install

npm install -S nommer

Import

import { nmExists, nmInstall, nmRemove } from 'nommer'

API

nmExists(szPath)

Check whether node_modules exist at (or one directory below) specified path

import { nmExists } from 'nommer'

// Assume "/path/containing/node_modules" is path to installed node_modules

(async () => {
  await nmExists() 
  // --> returns null
  await nmExists("/path/containing") 
  // --> returns true
  await nmExists("/path/containing/node_modules") 
  // --> returns true
  await nmExists("/path/") 
  // --> returns false
  await nmExists("/path/node_modules") 
  // --> returns false
})()

---

nmInstall(szPath)

Run npm install in specified directory

import { nmInstall } from 'nommer'

(async () => {
  await nmInstall() 
  // returns null; does nothing
  await nmInstall(process.cwd()) 
  // --> returns true; run npm install in cwd
  await nmInstall("path/to/child/module") 
  // --> returns true; run npm install in child module
})

---

nmRemove(szPath)

rm -Rf node_modules with some protection

Simple Protection

1. Is this a node_modules directory? If not, stop.
2. Is this the current working directory? If so, stop.

import { nmRemove } from 'nommer'

(async () => {
  await nmRemove() 
  // --> returns null; does nothing
  await nmRemove(process.cwd()) 
  // --> console warning: cannot remove cwd
  await nmRemove("path/containing/node_modules") 
  // --> returns true; removes modules
  await nmRemove("path/containing") 
  // --> returns true; removes modules
  await nmRemove("path/") 
  // --> returns false; does nothing
})
