Othernpm

Othernpm provides a way to run npm commands in other directories. A typical use of this module would be to run npm scripts of subdirectories that have own package.json.

Usage

CLI

Othernpm allows you to specify a path where npm commands run.

# 'cd ./templates && npm install'
% onpm ./templates install

You can also define paths in package.json and use them to specify a path.

{
  "name": "package name",
  ...
  "othernpm": {
    "examples": "./examples",
    "site": "./site"
  }
}

# 'cd ./site && npm run build'
% onpm site run build

# 'cd ./examples && npm test'
% onpm examples test

For example, this repository defines a npm-script named eg in its package.json. By this, we can run any npm command in test/example from the root directory like:

# Check defined npm-scripts in 'test/example'.
% npm run eg -- run

# Install Mocha as a dev-dependency of 'test/example'.
% npm run eg -- install --save-dev mocha

Node.js API

Othernpm also provides API used in Node.js scripts. The module loads configurations from package.json automatically so that you can use them as functions.

const onpm = require('othernpm');

// Run the 'start' script in the examples directory.
onpm.examples('start');

// Run the 'build' script in the site directory.
onpm.site('run build');

// Run npm commands in another directory.
onpm('./templates')('test');

The othernpm function returns a spawn object.

const build = onpm.examples('run build');
build.on('exit', exitCode => console.log(exitCode));

Installation

npm install --save-dev othernpm
