import-lazy Build Status

Import a module lazily

Note: Version 3 is exclusively Proxy-based and requires Node.js 6+. Use version 2 if you need Node.js <=5 support.

Install

$ npm install import-lazy

Usage

// Pass in `require` or a custom import function
const importLazy = require('import-lazy')(require);
const _ = importLazy('lodash');
 
// Instead of referring to its exported properties directly…
_.isNumber(2);
 
// …it's cached on consecutive calls
_.isNumber('unicorn');
 
// It also works using destructuring assignment in ES2015
const {isNumber, isString} = importLazy('lodash');
 
// Works out of the box for functions and regular properties
const stuff = importLazy('./math-lib');
console.log(stuff.sum(1, 2)); // => 3
console.log(stuff.PHI); // => 1.618033
