isrequirable

Node.JS utility function for returning a boolean if a module can be called via require().

Node has a function require.resolve() which returns the path of a module without loading it. However, it throws an error if the module is not found. There are cases when I don't want node to throw an error and this utility function is the solution. Just sharing it in case anyone finds it useful.

Installation

npm install isrequirable

Usage

var isrequirable = require('isrequirable');
 
if (isrequirable('async')) {
    var async = require('async');
} else {
    console.log('Cannot require async.');
}
