npm-install-if-needed

Node.js script to check if a project needs to run npm install

Usage

The script has no package-dependency, so you can use it even in every scenario.

When running the first time, the script adds semver as dev dependency in your package.json file. You can import the script with require directive and run

const npm_if_needed = require('./npm-install-if-needed');
npm_if_needed.installIfNeeded();

Or with options:

npm_if_needed.installIfNeeded({cwd: process.cwd(), ignoreScript:false, saveDev:true, packages:[]});

Options

You can pass some options to the function installIfNeeded:

• cwd: the current work directory when package.json file is located (default: process.cwd())
• ignoreScript: if true, add --ignore-scripts flag to npm install command (default: false)
• saveDev: if true, add --save-dev flag to npm install command (default: false)
• packages: array of npm packages to install when run the npm command (default: [])
