node-require-fallback

node-require-fallback

Require another package in Node.js if your first choice doesn't exist.

Useful for development, where you want to use a local copy of your package, but it shouldn't break the application for your team, which is depending an npm package.

Installation

npm install --save node-require-fallback

Example Usage

var requireIfExists = require('node-require-fallback');

var myModule = requireIfExists('module1', 'module2');

myModule will now hold module1 if it exists or module2 otherwise.
myModule will be null, if module2 wasn't available as well.
