The modern build of lodash exported as Node.js/io.js modules.
Generated using lodash-cli:
$ lodash modularize modern exports=node -o ./
$ lodash modern -d -o ./index.jsUsing npm:
$ {sudo -H} npm i -g npm
$ npm i --save lodashIn Node.js/io.js:
// load the modern build
var _ = require('lodash');
// or a method category
var array = require('lodash/array');
// or a method (works great with browserify/webpack to create smaller builds)
var chunk = require('lodash/array/chunk');See the package source for more details.
Note:
Don’t assign values to the special variable _ when in the REPL.
Install n_ for a REPL that includes lodash by default.
lodash is also available in a variety of other builds & module formats.
