Generate npm/yarn install commands base on package.json

• Node.js ≥ 6.0.0, and npm
• UNIX-like shell, e.g. sh, bash, zsh

npm install --global generate-npm-install

This will generate npm install --save-{prod,bundle,optional,dev} or yarn add {,--optional,--dev} commands base on package.json in working directory

generate-npm-install # output contains: npm install --save... package1 package2 ... NPM_TAG=latest generate-npm-install # output contains: npm install --save... package1@latest package2@latest ... USE_YARN=true generate-npm-install # output contains: yarn add ...

This will generate npm install commands for /path/to/directory/package.json

generate-npm-install /path/to/directory NPM_TAG=latest generate-npm-install /path/to/directory

This will execute generated npm install commands

generate-npm-install | sh NPM_TAG=latest generate-npm-install | sh generate-npm-install /path/to/directory | sh NPM_TAG=latest generate-npm-install /path/to/directory | sh

const generateNpmInstall = require('generate-npm-install')

generateNpmInstall(options: { process: { env: { TAG?: string, NPM_TAG: string = TAG, USE_YARN: string = 'false' } } = require('process'), fs: { readFileSync: (filename: string) => { toString: (encoding: string = 'utf8') => string } } = require('fs'), path: { resolve: (...args: string[]) => string } = require('path'), directory: string = process.cwd() }): string
